# solana-codemod

> Automated migration from @solana/web3.js v1 to @solana/kit (v2). jscodeshift-based AST transforms. 6 transforms, 26 tests.

## Usage

Run all transforms: `npx solana-codemod ./src`
Specific transform: `npx solana-codemod ./src -t public-key-to-address`
Dry run: `npx solana-codemod ./src --dry`

## Transforms

1. `public-key-to-address` - new PublicKey("...") → address("..."), PublicKey type → Address
2. `connection-to-rpc` - new Connection(url) → createSolanaRpc(url), appends .send() to RPC calls
3. `keypair-to-signer` - Keypair.generate() → await generateKeyPairSigner(), auto-adds async
4. `system-program-transfer` - SystemProgram.transfer → getTransferSolInstruction, renames props
5. `transaction-to-pipe` - new Transaction() + .add() → pipe(createTransactionMessage(...))
6. `rewrite-imports` - cleans up @solana/web3.js imports, deduplicates @solana/kit imports

## Not covered (manual migration needed)

VersionedTransaction, connection.sendTransaction(), subscription methods, BN to BigInt, Anchor IDL clients, @solana/spl-token v1 to v2.
