Automatically migrate your codebase from @solana/web3.js v1 to @solana/kit.

bash

What It Does

10 deterministic transforms. ~85% automation coverage. Zero false positives.

Transform	What changes
`01-imports`	`@solana/web3.js` → `@solana/kit` named imports
`02-connection`	`new Connection(url)` → `createSolanaRpc(url)`
`03-publickey`	`new PublicKey('str')` → `address('str')`
`04-keypair-generate`	`Keypair.generate()` → `await generateKeyPairSigner()`
`05-keypair-props`	`.publicKey` → `.address`, `.secretKey` → `.privateKey`
`06-system-transfer`	`SystemProgram.transfer({...})` → `getTransferSolInstruction({...})`
`07-send-confirm`	`sendAndConfirmTransaction(conn, tx, [s])` → kit signature
`08-cluster-api-url`	`clusterApiUrl('devnet')` → `'https://api.devnet.solana.com'`
`09-rpc-send`	`rpc.getBalance()` → `rpc.getBalance().send()` (all 40+ RPC methods)
`10-type-annotations`	`PublicKey`, `Keypair`, `TransactionInstruction` type annotations → kit equivalents

Before:

typescript

After:

typescript

These patterns are intentionally left for human review:

Keypair.fromSecretKey(bytes) → use createKeyPairSignerFromBytes()
new PublicKey(buffer) → non-string PublicKey construction
Multi-instruction Transaction.add().add() chains → rewrite to pipe() pattern
Commitment level configuration → must move to per-call options
sendAndConfirmTransactionFactory wiring → requires rpc + rpcSubscriptions in scope

bash

Transforms are numbered — run them in order (01 → 10) if applying manually.

24 test fixtures across all 10 transforms. All passing.
