v0.12.0

Summary

Added optional addressResolver override for autoload:

const result = await whatsabi.autoload(address, {
  provider: provider,
  // ...
  // Example: Use viem to resolve ENS addresses
  addressResolver: async (name) => {
    return await publicClient.getEnsAddress({ name })
  },
}

Otherwise minor improvement to disassembling and the test suite.

What's Changed

• disasm: Detect inverted selector jump condition (with fallback) by @shazow in #85
• auto: Add addressResolver config by @shazow in #91
• src/tests/env.ts: Use public RPC by @shazow in #92

v0.11.0

Summary

Our ABI loaders learned about contract metadata with ABILoader.getContract(address): Promise<ContractResult>, thanks to @SonOfMosiah!

const loader = new whatsabi.loaders.SourcifyABILoader();
// Previously: const abi = await loader.loadABI(address);
const { abi, name, evmVersion, compilerVersion, runs, ok } = await loader.getContract(address);
if (!ok) throw new Error("contract not found");
...

What's Changed

• README, .env.example: Add env example by @shazow in #79
• feat: getContract by @SonOfMosiah in #77
• loaders: getContract returns non-nullable ContractResult by @shazow in #81
• Release v0.11.0 by @shazow in #82

v0.10.1

Summary

• loaders.defaultsWithApiKeys is now loaders.defaultsWithEnv, supporting more overrides: SOURCIFY_CHAIN_ID, ETHERSCAN_BASE_URL, ETHERSCAN_API_KEY (thanks @SonOfMosiah).

Example:

const result = await whatsabi.autoload(address, {
  provider: provider,
  ... whatsabi.loaders.defaultsWithEnv({
    SOURCIFY_CHAIN_ID: 42161,
    ETHERSCAN_BASE_URL: "https://api.arbiscan.io/api",
    ETHERSCAN_API_KEY: "MYSECRETAPIKEY",
  }),
});

What's Changed

• Add a baseURL param to defaultsWithAPIKeys by @SonOfMosiah in #73
• loaders.defaultsWithEnv by @shazow in #74
• Switch to tsx, pnpm update by @shazow in #75

• @SonOfMosiah made their first contribution in #73

Full Changelog: v0.10.0...v0.10.1

v0.10.0

Summary

• loaders.defaultsWithAPIKeys(env) [Update: Use loaders.defaultsWithEnv in v0.10.1]: New helper for initializing default loaders with your own API keys (and more):

  const env = { ETHERSCAN_API_KEY: "<YOUR KEY>" }; // or process.env
  const r = await whatsabi.autoload(address, {
    provider,
    ...whatsabi.loaders.defaultsWithEnv(env),
  });

• proxies.DiamondProxy now knows how to load all registered facets with proxy.facets(provider, address) or proxy.selectors(provider, address). Shoutout to @banteg for helping figure this out.
• selectorsFromBytecode will now return as soon as the jump table is processed, for faster performance when just extracting selectors.
• Shoutout to @cdump for making and sharing a benchmarking suite (#66), this prompted several improvements to whatsabi (false positives should be fixed, and performance improved). Also check out evmole, the bytecode-based parameter type guessing is very impressive!

What's Changed

• Fix syntax issues in the code in the 'usage' section of README by @Autosaida in #64
• DiamondProxy: Load internal facets and selectors by @shazow in #65
• disasm: Fix false positive selectors when looking for ISZERO selectors by @shazow in #68
• examples/benchmark-selectors.ts: Add benchmark example, improve selector loading performance when bypassing full parsing by @shazow in #71

• @Autosaida made their first contribution in #64
