Early Builders Program

Free Hyperliquid API access for pre-revenue teams. Up to 1 million GoldRush credits over 12 months, monthly cohorts, REST and WebSocket from day one.

The Early Builders Program gives pre-revenue Hyperliquid teams free access to the GoldRush API - up to 1 million credits over 12 months. We run monthly cohorts with limited spots, so we can actually get to know the teams we’re backing.

GoldRush has been indexing onchain data since 2018. Hyperliquid is one of the most data-rich environments in crypto, and this program puts the full surface in your hands from day one - no infra to run, no schemas to design.

Apply now

~5 minutes. We respond as soon as we’ve reviewed your application.

Who can apply

Two tracks. Apply on the one that fits.

Data-native apps

You’re building an app where data is the core value - portfolio tracker, trader analytics, leaderboard, alert system, or similar.

• Must be non-custodial.
• Must not include trading execution.

Builder code apps

You’re building an app you plan to monetize, but can’t commit to a paid plan today.

• Share your app, your team, and your Hyperliquid builder address.
• Get full GoldRush API and WebSocket access while you build.
• Billing starts when your builder wallet starts generating revenue from users.

What’s included

Approved teams get the same surfaces our paid customers use:

Surface	What you get	Where to start
Hyperliquid Info API	Drop-in replacement for POST https://api.hyperliquid.xyz/info with POST https://hypercore.goldrushdata.com/info. Same request body, no rate limits, faster orderbook reads, batched user state, builder-attribution data, and HIP-4 outcome metadata.	Info API Overview
Hyperliquid WebSocket API	Drop-in replacement for wss://api.hyperliquid.xyz/ws with wss://hypercore.goldrushdata.com/ws. Same subscription payloads, no 1000-subscription-per-IP cap, and coin is optional on l2Book (stream every asset on one subscription). Adds the GoldRush-native l2BookDiff L2 snapshot-plus-diff stream (single coin, list of coins, or wildcard) and l4Book order-level diff stream with user, oid, cloid, and trigger metadata per order.	WebSocket API Overview
Foundational API	HyperEVM token balances, transfers, approvals, NFTs, gas, blocks.	HyperEVM Chain Page

Program details

• Cost. Free while you qualify. Up to 1 million credits per team across cohorts, redeemable over 12 months.
• Eligibility. Strictly pre-revenue teams. Either data-native (non-custodial, no trade execution) or builder code (with a builder address).
• Rate limits. No public Hyperliquid /info rate limits and no GoldRush WebSocket subscription cap during the program. See Hyperliquid API limitations addressed by GoldRush.
• After 12 months or first revenue. You move to a paid plan that fits your usage. We reach out before that happens with options based on your traffic shape and (for builder code apps) your builder revenue.
• Review SLA. We don’t queue applications for weeks. If you’ve applied and haven’t heard back, ping us.
