Contract Utilities

Utilities to fetch and parse contract ABI and sources from any imported contracts.

Getting the ABI of a contract​

You can obtain the ABI of any contract with the following code:

const sdk = new ThirdwebSDK(chain, {
  // pass your cliendId or secretKey...
});

const contract = await sdk.getContract("0x...");
const ABI = contract.abi;

Getting all functions and events definitions from a contract​

Get parsed function and event definitions from a contract:

const sdk = new ThirdwebSDK(chain, {
  // pass your cliendId or secretKey...
});

const contract = await sdk.getContract("0x...");
const functions = await c.publishedMetadata.extractFunctions();
const events = await c.publishedMetadata.extractEvents();

Getting the sources of a contract​

To get the source code of a deployed contract:

const sdk = new ThirdwebSDK(chain, {
  // pass your cliendId or secretKey...
});

const contract = await sdk.getContract("0x...");
const sources = await contract.publishedMetadata.extractSources();

Getting the implementation address of a Proxy​

Resolve the implementation address and bytecode of a given proxy contract

const sdk = new ThirdwebSDK(chain, {
  // pass your cliendId or secretKey...
});

const { address, bytecode } = await resolveImplementation(
  "0x...", // the proxy address
  sdk.getProvider(),
);
console.log("Implementation address", address);
