SolIndex — embeddable Solana program/account indexer SDK with realtime websockets

PublicWeb3-infraOn-chain-dataSolanaDevTools

TypeScript SDK that wraps Helius/Triton RPCs and the Metaplex/Anchor IDLs to give a viem-style read API for Solana: typed getAccount, getProgramAccounts with memcmp filters, and event subscriptions via WebSocket.

PROBLEM

EVM tooling (wagmi, viem) feels cohesive; Solana tooling is a patchwork of @solana/web3.js, anchor, and a different IDL loader per program. Web3 developers coming from EVM have to relearn pagination, memcmp filters, base58+base64 encoding quirks, and slot-based confirmations. There is no 'wagmi for Solana' that exposes a typed, event-driven read API.

TARGET USER

Web3 developers coming from EVM (the persona's exact learning path) and indie hackers who want to ship a Solana dApp without a week of relearning.

MVP SCOPE

NPM package `@solindex/sdk` that wraps Helius RPC + a typed program registry (Token, Token-2022, Metaplex, Jupiter); React hooks for useProgramAccount, useProgramAccounts (with memcmp), useProgramEvents via WebSocket; Next.js example app.

WHY ME

I'm explicitly learning Solana; building the tool is the fastest way to learn, and EVM expertise (viem patterns, wagmi hooks) is the unfair advantage that lets me port those abstractions over correctly.

WHY A GENERALIST CAN'T BUILD IT

Requires knowing the difference between getMultipleAccounts and getProgramAccounts (memcmp/dataSize filters), the base58 vs base64 encoding rules for memcmp, the slot vs block confirmation model, Anchor account discriminator (first 8 bytes of sha256('account:Name')), and Token-2022 extension decoding.
