The problem
Plain Solana RPC is generous, free, and self-serve. The trade-off is that any product that needs wallet balances with token metadata and pricing ends up stitching togethergetTokenAccountsByOwner, per-mint metadata lookups, and price sources.
GoldRush ships the primitive below as decoded, typed data over REST. SPL transfer history, Solana transactions, NFTs, and pricing REST endpoints are not covered today.
SPL token balances for a wallet
Public RPC requires agetTokenAccountsByOwner call plus per-mint metadata lookups. GoldRush returns SPL balances with mint metadata and USD pricing where available in one REST call.
