Assorted checks and validations for writing safer Solana programs.

Motivation

Solana's fee mechanism is unlike Ethereum's, in that the number of bytecode instructions executed does not add to the cost of a transaction. Due to this, it is wise to design Solana code with excessive safety checks in order to minimize the chance of exploits.

This library provides several utilities for Anchor programs to validate account structs and check for invariants.

    Release notes

    v0.21.0

    For a list of changes in this release, see the Change Log.

    Changelog

    Sourced from anchor-lang's changelog.

    [0.21.0] - 2022-02-07

    Fixes

    • ts: Fix the root type declaration of the Wallet / NodeWallet class (#1363).
    • ts: Improve type mapping of Account fields into Typescript with additional support for Option<T> and Vec<String> types (#1393).

    Features

    • lang: Add seeds::program constraint for specifying which program_id to use when deriving PDAs (#1197).
    • lang: Context now has a new bumps: BTree<String, u8> argument, mapping account name to bump seed "found" by the accounts context. This allows one to access bump seeds without having to pass them in from the client or recalculate them in the handler (#1367).
    • lang, ts: Automatically infer PDA addresses (#1331).
    • ts: Remove error logging in the event parser when log websocket encounters a program error (#1313).
    • ts: Add new methods namespace to the program client, introducing a more ergonomic builder API (#1324).
    • ts: Add registry utility for fetching the latest verified build (#1371).
    • cli: Expose the solana-test-validator --account flag in Anchor.toml via [[test.validator.account]] (#1366).
    • cli: Add avm, a tool for managing anchor-cli versions (#1385).

    Breaking

    • lang: Put init_if_needed behind a feature flag to decrease wrong usage (#1258).
    • lang: rename loader_account module to account_loader module (#1279)
    • lang: The Accounts trait's try_accounts method now has an additional bumps: &mut BTreeMap<String, u8> argument, which accumulates bump seeds (#1367).
    • lang: Providing bump = <target> targets with init will now error. On init only, it is required to use bump without a target and access the seed inside function handlers via ctx.bumps.get("<pda-account-name"). For subsequent seeds constraints (without init), it is recommended to store the bump on your account and use it as a bump = <target> target to minimize compute units used (#1380).
    • ts: Coder is now an interface and the existing class has been renamed to BorshCoder. This change allows the generation of Anchor clients for non anchor programs (#1259).
    • cli: [[test.clone]] key in Anchor.toml is renamed to [[test.validator.clone]] (#1366).
