New (Non-Breaking) Import Statement for GoldRush SDKs

https://goldrush.dev/docs/unified-api/quickstart/typescript-sdk/

Following the rebrand of Covalent’s data products to “GoldRush”, the following import statement is now supported through the SDKs: import { GoldRushClient } from "@covalenthq/client-sdk";

This is a non-breaking change, so projects using import { CovalentClient } from "@covalenthq/client-sdk"; will be unaffected.

​
New Premium Wallet Activity Endpoint

For wallet apps, making multiple API calls to see if an address has activity on a certain blockchain is costly and inefficient.

To solve this issue, GoldRush has beta released a new Wallet Activity endpoint - exclusively available to Premium users!

This endpoint streamlines wallet development by locating where an address is active across 100+ chains with a single API call, returning the last active timestamp.

​
Address Activity Endpoint Goes Public

https://www.covalenthq.com/blog/identify-address-activity-across-100-chains/

In May, we exclusively released a beta version of an Address Activity endpoint to Premium users.

Now, we’re excited to officially release Get address activity to all GoldRush API users!

This endpoint enables you to locate where a wallet address is active across 100+ chains with a single API call and returns the last active timestamp.

Forget wasting API calls to check for activity on each individual blockchain - use the address activity endpoint as your blueprint!

​
New GoldRush SDK, Typescript and Python

We’ve just released the GoldRush SDK, a comprehensive tool for modern developers that allows you to use function calls instead of HTTP requests!

Many users have had to create internal clients in the past, which are often lacking certain data and miss out on updates to our API.

To improve the developer experience, we’ve created a Typescript SDK and a Python SDK, offering comprehensive coverage of our endpoints grouped under various Services.

Save time and code easier with the GoldRush SDK!

​
Sunsetting Boba Avalanche

As of October 31, 2023, Boba is sunsetting the Boba Avalanche network. GoldRush API support for both Boba Avalanche mainnet and testnet will no longer be available.

​
New Viem-Compatible Client SDK

We now offer The Covalent Viem SDK, developed in TypeScript, which leverages the viem framework to offer a seamless integration path with the GoldRush API.

Reduce the number of API calls required to power your application and gain access to Covalent’s detailed, historical data across 200+ blockchains.

​
Cached NFT Thumbnail Data Added

We just majorly updated our NFT endpoints with new cached thumbnail data!

This update includes several key fields: thumbnails, which provide various sizes of asset thumbnails like image_256, image_512, image_1024, and image_opengraph_url, tailored to different use cases including OpenGraph protocol; image_preview, an unmodified thumbnail of the asset; and asset_properties, detailing dimensions and the dominant color of the asset.

Devs can also benefit from the thumbhash feature, which allows for the decoding of thumbnail hashes into a blurred image preview, useful for enhancing loading experiences and privacy in NFT galleries and marketplaces.

This suite of enhancements supports a wide range of asset types, from images and videos to audio files, catering to diverse NFT displays.

​
Current NFT Owner Data Added

We’ve added a current_owner field to our NFT ownership endpoints:

The current_owner field gives you the wallet address of the current owner of that NFT. This new feature applies to all chains with NFT support.

​
Introducing GoldRush Decoder: Decode, Visualize, Understand

In November 2023, we launched GoldRush Kit, a series of customizable React components for dApp frontends. Now, we introduce GoldRush Decoder, a transformative tool that translates raw log events from blockchain transactions into structured, human-readable formats.

GoldRush Decoder pairs directly with GoldRush Kit for easy visualization, however, it can be used as a standalone tool.

Traditional block explorers keep their data transformations private and inaccessible to users. GoldRush Decoder is different. This open-source tool acts as a public good for decoded data.

​
CrossFi Testnet, Syndr Testnet, Celo and Taiko Katla Testnet Indexed

CrossFi Testnet, Syndr Testnet, Taiko Katla Testnet and Celo are now fully indexed! Users can query all on-chain data through our Class A endpoints.

New Gas Parameter in Transaction Summary Endpoint

We recently added a new with-gas query parameter to the Get transaction summary for address endpoint.

This endpoint is commonly used to fetch the earliest and latest transactions, and the total transaction count for a wallet. The new with-gas parameter allows you to see the total gas quote for the wallet, as well as the average quote per transaction, and other insightful metadata.

​
New Gas Prices Endpoint

We just added a new endpoint; Get gas prices!

This endpoint enables users to get real-time gas estimates for different transaction speeds on a specific network, for the following event types:

  • erc20 token transfers
  • nativetokens transfers
  • uniswapv3 swap events

Using these estimates, optimize your transaction costs and/or build your own gas tracker!

Note: the l1_gas_quote field is only relevant for queries on OP stack chains like Optimism, Base, etc.

​
Decibling, StarkSport and Public zkSync Indexed

The Lumoz Rollups Decibling, StarkSport and Public zkSync are now fully indexed! Users can query all on-chain data through our Class A endpoints.

​
New Approvals Endpoint

https://www.covalenthq.com/blog/covalent-solves-for-approvals-risk-protecting-user-funds/

Covalent has released a new approvals endpoint that shows you all the approvals across all token contracts categorized by spenders for a wallet’s assets.

This new endpoint shows you the value of assets at risk for a wallet. Basically, if the spender were to be hacked, the value at risk is how much they could stand to lose.

Get approvals is currently available on Ethereum, BNB Smart Chain and Polygon and will be added to all remaining supported networks in a few weeks!

​
New XY=K Endpoints

https://www.covalenthq.com/blog/xyk-announcement/

Covalent has introduced a list of Class B endpoints under the XY=K family which provide the richest and most robust on-chain DEX data available today.

​
New Solana Balances Endpoint

https://www.covalenthq.com/blog/solana-balances-announcement/

Covalent launches non-EVM support with Solana balances, bringing the industry-leading unified API experience to tens of thousands of developers in the Solana ecosystem. The Get token balances for address endpoint enables developers to fetch token balances including NFTs for any wallet address on Solana with a single API call. With this new data, developers can include Solana assets in multi-chain crypto wallets, NFT galleries and more. This is just step one in the process of fully indexing Solana across all of our Class A endpoints.

​
New NFT Endpoints Added

This month we expanded our ever-growing suite of NFT endpoints to include:

Try them out!

​
Bitcoin, Class C, New Transactions Endpoints and Updates to Premium API

This month, we unveiled support for Bitcoin as part of our new class of endpoints: Class C!

Class C is the next generation of endpoints, which partners and community members can build using SQL.

Users can now access Bitcoin balance and transaction data through the Class C section on our docs and other protocols like Aave, Compound and Lido.

Additionally, we released new transactions endpoints allowing users to get transactions by block and get all transactions for large addresses with reliable pagination.

Lastly, the Covalent Premium API tier now supports BNB Smart Chain (BSC) through the balances endpoint! This means Premium users will get access to 50 requests per second when querying token balances on Binance.

​
New NFT Endpoints

With so much growth in the NFT sector, we saw fit to expose better pathways to this data with NFT transactions, traits, attributes, ownership and more. We released a new suite of NFT endpoints offering:

Try them out!

​
New Token Holders Endpoint

We just released a new token holders endpoint, supporting ERC20, ERC721, and ERC1155 tokens. This endpoint will have the same parameters as the original one we deprecated, apart from page-size, which is fixed at 100. Users can fetch historical token holders with the parameter block-height.

​
New Transactions Endpoints

This month we’ve released two new transaction endpoints amid a series of product updates that help simplify wallet development. Check them out:

  1. Get transaction summary for address - This endpoint allows you to get the earliest and latest transactions for an address as well as a total count, giving you quick insights into a user’s activity.
  2. Get earliest transactions for address - This endpoint gives all the decoded details of the very first transaction by a wallet on a chain. From there you can use the next URL to continue bulk fetching the transaction history.

​
Multiple Lumoz Rollups Indexed; Opside Chain Pre-Alpha Testnet, Opside Public zkEVM, XThrill, Era7, CB zkEVM and LAW Chain

https://www.covalenthq.com/faucet/?utm_source=mantle&utm_medium=twitter&utm_campaign=testnet-faucet&utm_id=faucet

Our Testnet Faucet now supports Mantle, providing free test MNT for developers who want to build and test their dApps on the Mantle Testnet.

This faucet drips 100 MNT!

​
Sunsetting Bobabeam and Bobabase

The Boba team has sunsetted the Bobabeam and, therefore, Bobabase appchains. These networks have been marked as suspended on our Supported Networks page and will no longer be supported.

​
New Historical Bitcoin Balances

We’ve added a new endpoint that retrieves the historical token balances for a wallet address at a specified date or block height!

GET /v1/{chainName}/address/{walletAddress}/historical_balances/

Currently, this endpoint is exclusive to the Bitcoin blockchain. Use chainName: btc-mainnet or 20090103.

Example query structure:

Stay tuned for Ethereum, Polygon and BNB Smart Chain support!

​
Lens Address Resolution Added

Lens Protocol address resolution is now supported through our API! Now, you can substitute a Lens handle wherever an address is usually required. This enhancement simplifies address inputs and allows you to build unique, user-friendly applications in the Lens ecosystem. Try it out

​
Light NFT Responses Added

We’ve added a new query parameter called no-nft-asset-metadata to the Get token balances for address and Get NFTs for address endpoints.

If  true, the response shape is limited to a list of collections and token ids, omitting metadata and asset information.

This produces faster response times, which is helpful for wallets holding a lot of NFTs. These light NFT responses enable to developers to optimize their applications by querying only the required NFT metadata.

​
NFT Asset and Metadata Caching for Arbitrum and Optimism

https://www.covalenthq.com/docs/unified-api/data-coverage/

Often, NFT token metadata and assets are tucked away off-chain, hidden behind APIs with strict rate limits, presented in non-uniform formats, and bundled with oversized files – not to mention the lack of thumbnails and unoptimized images.

Covalent simplifies this process by downloading and caching the metadata, assets, and related information to create a smooth developer experience.

So far, we’ve cached over 100 million assets between Ethereum, Polygon and BNB. Now, we’ve started the process of crawling Arbitrum and Optimism. Monitor the progress on our data coverage page below!

​
Neon Mainnet Indexed

Neon mainnet, an EVM on Solana, is now fully indexed! Users can query all on-chain data through our Class A endpoints.

​
Gas Metadata Added

We’ve added new gas_metadata fields to our transactions endpoints!

Previously, transactions responses only included the gas fee amounts, but it did not have what the gas fees are denominated in. This caused practical problems, such as the inability to render the name of the network token that’s attached to a transaction.

Now, all transactions responses have gas_metadata fields attached to them, taking the guess work out of your frontend and making it east to render contract details like contract name, ticker symbol, logo, and address.

​
New Testnet Faucet

https://www.covalenthq.com/faucet/?utm_source=linea&utm_medium=social&utm_campaign=testnet-faucet&utm_id=faucet

We just released a new Testnet Faucet with our partners Linea and Base, providing free testnet ETH for developers who want to build on Linea Testnet and Base Testnet.

Features:

  • 24-hour cooldown period: the cooldown period helps to maintain a fair distribution system and prevent malicious users.
  • Smooth UX: the simple and intuitive interface is designed to streamline the process of getting testnet tokens.
  • (coming soon) Multi-chain token dispensation: soon this faucet will expand to more supported networks to make it easier for developers to deploy and test their dApps in a variety of ecosystems.

​

​
MELD and Gunzilla Testnets Indexed

The Avalanche Subnets MELD Testnet and Gunzilla Testnet are now fully indexed! Users can query all on-chain data through our Class A endpoints.

​
New Human-Readable Transactions

We are thrilled to announce a significant enhancement to our Get a transaction endpoint - new human-readable event fields!

To address the lack of standardization across blockchains and protocols, we’ve semantically decoded a broad spectrum of information for DEX trades, lending and NFT sales.

The new response includes protocol labels, logos, token pair information, and the following labelled events:

DEX events

  • add_liquidity
  • pair_created
  • remove_liquidity
  • swap

Lending events

  • borrow
  • deposit
  • flashloan
  • liquidation
  • repay
  • withdraw

NFT sales

We’ve reverse-engineered the array of transaction types that occur in NFT sales across different markets to provide a consistent, easy-to-understand format like “Harry.eth sent Sally.crypto this monkey NFT”.

​
SKALE Appchains Indexed; 0xBattleGround and Nebula Gaming Hub

The SKALE appchains 0xBattleGround and Nebula Gaming Hub are now fully indexed! Users can query all on-chain data through our Class A endpoints.

​
Multiple Blockchains Indexed; Dexalot, Calypso, Omnus/Cryptoblades, Razor and Europa Hub

​
New Testnets Indexed; Base, Polygon zkEVM, ConsenSys zkEVM, Scroll Alpha

The Base Testnet, Polygon zkEVM Testnet, ConsenSys zkEVM Testnet and Scroll Alpha Testnet are now fully indexed! Users can query all on-chain data through our Class A endpoints!

​
Multiple Blockchains Indexed; Oasis Sapphire, Mantle, KCC, Oasys, Findora and SX Network

In the month of March, we indexed another handful of new blockchains, including Oasis Sapphire, Mantle, KCC, Oasys, Findora and SX Network. Users can query all on-chain data for these chains through our Class A endpoints. This brings our total count of blockchains supported at the end of Q1 2023 to over 100!

​
Multiple Blockchains Indexed; CLV Parachain, Energi and Horizen EON Testnets

The CLV Parachain and Energi blockchains are now fully indexed along with Horizen EON Testnets, Yuma and Gobi! Users can query all on-chain data through our Class A endpoints.

​
Sepolia Testnet Indexed

We’ve indexed the Sepolia Testnet - Ethereum’s recommended default testnet for application development! Users can query all on-chain data through our Class A endpoints.

​
New Pretty Value Quotes

If you’ve used the Covalent API to fetch balances or transactions before, you’re probably familiar with the quote field which denotes the value of token amounts in fiat currency. The default currency is USD, but developers can change this with the query parameter quote-currency!

This month, we augmented this already-popular feature to include additional “pretty” quotes, which come with a dollar sign ($) and rounded decimals. This makes it even easier to build user-friendly interfaces, minimizing data transformations for developers.

You can find pretty_quote, pretty_gas_quote, pretty_quote_24h and pretty_value_quote throughout all relevant Class A endpoints!

​
NFT Spam Field Added

We added an is_spam field to the following endpoints:

This field returns true if an NFT is part of a collection that is flagged as spam, and is useful for filtering out spam NFT data, protecting users from interacting with scammy or fraudulent tokens, and overall improving user experience.

This field is currently supported on Ethereum and Polygon and will soon be expanded to more chains.

​
Spam Filter Parameter Added

Following the recent release of our is_spam field that indicates whether or not an NFT is part of a collection flagged as spam, we’ve added a new no-spam query parameter that allows you to filter out spam contracts & transactions!

The no-spam parameter is supported for the following endpoints:

If is_spam returns true the suspected spam NFT is removed.

This feature is currently supported for eth-mainnet and matic-mainnet.

​
New Premium Endpoints Added

https://www.covalenthq.com/docs/unified-api/pricing/

In April, we upgraded the following endpoints to the Premium API tier:

These endpoints will now count against monthly Premium credits. Check out our pricing page for more details by clicking the button below.

​
Credit Changes to Free Endpoints

https://www.covalenthq.com/docs/unified-api/pricing/

Starting April 1, 2023, we are changing the credit rate for select Free endpoints. These endpoints will count against the monthly Free tier credit cap of 100,000 API credits.

The endpoints with associated credit rate changes are:

For a detailed breakdown of each endpoint and credit rate, please see our pricing and rates card page here.

If you require a higher volume of API credits beyond 100,000 per month, switching to our Premium plan gets you unlimited access to Free endpoints, higher rate limits, and other perks.

Some of these Free endpoints will also be converted to Premium endpoints in the future, meaning they will count against the included number of credits in the Premium tier and beyond that as Flex credits. Endpoints added to the Premium tier will feature benefits like support for 50 requests per second, faster response times and decreased response time variance.

​
Covalent Soft-Launches Premium API with Select Users

https://www.covalenthq.com/docs/unified-api/pricing/

The Premium tier is available for users who want to scale with us. The Covalent Unified API has always been free and will always have a free tier. We believe in making data easily accessible, but that has led us to rate limit this shared resource to maintain a good experience for everyone. In the Premium tier, we are adding updated endpoints with faster and more reliable engines in the backend, allowing us to support higher RPS and a higher volume of requests.

The launch of the Covalent Premium API exclusively features our most popular endpoint: Get token balances for address on the Ethereum blockchain, and is currently only available to select users. In 2023 the Premium API will go public and include multiple upgraded endpoints.

​
Astar Indexed

The Astar blockchain is now fully indexed! Users can query all on-chain data through our Class A endpoints. We’ve also added support for ArthSwap to our XY=K DEX endpoints.

​

​
Cronos Indexed

The Cronos blockchain is now fully indexed! Users can query all on-chain data through our Class A endpoints. We’ve also added support for MMF and VVS Finance to our XY=K DEX endpoints.

​
New Chain Name Feature

We added a feature that allows users to pass in human-readable, non-numeric chain IDs -these are chain names. For example, instead of specifying chain_id as 1 for Ethereum Mainnet, users can now use the chain-name: eth-mainnet. This feature becomes helpful when chain IDs become particularly large and/or hard to remember in cases like Palm (11297108109) and Harmony (1666600000).

To get the network name to use for the chain_id, refer to the name field of the Get all chains endpoint response.

We’ve also updated our Get transactions for address endpoint with a pagination improvement. Previously, this endpoint would timeout for addresses with too many transactions. Now the user can specify the page-number parameter with small values and the endpoint will successfully retrieve those transactions.

Additionally, we fixed an issue where the fees_paid field was null in the Get a transaction and Get transactions for address endpoints’ response.

​
Multiple Blockchains Indexed; Gather, Oasis, Scroll and Boba

This month we have rapidly indexed a handful of appchains!

This includes Gather Network, the Oasis Emerald ParaTime blockchain, the Scroll ZK-rollup (in its Pre-Alpha Testnet phase) and Boba Network! Users can query all on-chain data through our Class A endpoints.

The Boba Network includes the following supported Layer 1 blockchains: Ethereum, BNB Smart Chain, Avalanche, and Moonbeam.

​
New Balances Engine Complete

Covalent’s Get token balances for address endpoint has long been a favourite of our developer community. This year, we rebuilt the entire backend engine powering this endpoint in order to support our rapidly growing user base and their applications. In November, we completed QA testing and seemlessly made the switch from balances_v2 to balances_v3. This is the first of many upgrades to our existing endpoints in order to build for scale, and the next release will be transactions.

​
Covalent Balances Endpoint Available Now Available Through NodeReal

https://www.covalenthq.com/blog/covalent-nodereal-announcement/

In a partnership with blockchain infrastructure provider NodeReal, Covalent’s best-in-class balances endpoint is now available through the NodeReal Web3 API Marketplace. This integration makes it easy for developers to go beyond the RPC layer with aggregated blockchain data across multiple chains, starting with Ethereum mainnet.

New NFT Market Data Endpoints

https://www.covalenthq.com/blog/nft-market-data-announcement/

Covalent has introduced 2 new Class A endpoints which provide granular NFT market data for numerous marketplaces across 5 blockchains – Ethereum, Binance Smart Chain, Polygon, Avalanche, and Moonriver. The new endpoints provide both a global view of NFT collections ranked by market cap, as well as a detailed view of historical sale and floor price information for a particular collection. Thus far, it’s been hard to understand markets outside of Ethereum/OpenSea. These APIs address this gap by providing unprecedented access to this much-requested on-chain data.
