v2.0.0-rc.0 (2024-07-31)

This is an open invitation to test out what we intend to release as v2.0. Your feedback in these final moments before release will help us catch any bugs and rough edges that we missed during development.

To install the Release Candidate:

npm install --save @solana/web3.js@rc
  • Try the runnable examples in the examples/ directory to get a feel for the API.
  • Use the example dApp at https://solana-labs.github.io/solana-web3.js/example/ – source available here – for an example of how to build transactions with the new web3.js for use with wallets.
  • Install TypeScript clients for on-chain programs like System and Token, then build a useful application or backend service.

Before the general release of web3.js, shortly before Breakpoint 2024 in September, we want to collect as much feedback as possible from you. If you find a bug, are missing a feature, or would like an API modified, file a GitHub Issue.

Changelog since Technology Preview 4

  • #2907 677a9c4 Thanks @steveluscher! - __DEV__ mode will now be the default if you don't set process.env.NODE_ENV at all. This means fewer people ‘accidentally’ finding themselves in production mode with minified error messages.
  • #2905 56fde06 Thanks @steveluscher! - Fixed the type of config on getComputeUnitEstimateForTransactionMessage. It is now optional and does not include transactionMessage.
  • #2968 9239e6e Thanks @lorisleiva! - Tighten return type of isProgramError
  • #2928 bac3747 Thanks @steveluscher! - Added a useSignIn hook that, given a UiWallet or UiWalletAccount, returns a function that you can call to trigger a wallet's ‘Sign In With Solana’ feature.
  • #2950 29821df Thanks @mcintyre94! - Refactor rpc-spec to remove requirement for transports to implement parts of JSON RPC spec
  • #2910 42a70f4 Thanks @Jac0xb! - Fixed a bug where the RPC would fail to throw errors in the event that you configured it with an AbortSignal
