This package contains utilities for converting from legacy web3js classes to the new data structures. It can be used standalone, but it is also exported as part of the Solana JavaScript SDK @solana/web3.js@next.

Functions

fromLegacyPublicKey()

This can be used to convert a legacy PublicKey object to an Address type

import { fromLegacyPublicKey } from '@solana/compat';
const address = fromLegacyPublicKey(new PublicKey('49XBVQsvSW44ULKL9qufS9YqQPbdcps1TQRijx4FQ9sH'));
Copy

fromLegacyKeypair()

This can be used to convert a legacy Keypair object to a native Ed25519 CryptoKeyPair object

import { fromLegacyKeypair } from '@solana/compat';
const { privateKey, publicKey } = await fromLegacyKeypair(Keypair.generate());
Copy

fromVersionedTransaction

This can be used to convert a legacy VersionedTransaction object to a Transaction object.

import { fromVersionedTransaction } from '@solana/compat';

// imagine a function that returns a legacy `VersionedTransaction`
const legacyVersionedTransaction = getMyLegacyVersionedTransaction();
const transaction = fromVersionedTransaction(legacyVersionedTransaction);
