## Solana Kit

`@solana/kit` is the recommended TypeScript SDK for building on Solana. You
assemble a client from composable plugins, add React bindings when you need
them, and pull in generated program clients for the on-chain programs you call.

### Program clients

Generated clients that expose instruction builders and client plugins (for
example `tokenProgram()` → `client.token`).

## Signing & Key Management

For kit-compatible backend signing across multiple key management backends:

custody-model guidance.

## Solana Web3.js

`@solana/web3.js` is the legacy TypeScript SDK for Solana. New apps should use
`@solana/kit`; see [Migrating to Kit](/docs/frontend/web3-compat).
