ABIs (download) - YouthChain

This page hosts the full ABI JSON for every contract on the testnet. Drop these into your ethers/wagmi/viem app to read or write any function.

ABIs are auto-generated by Foundry from the contract source. They match the bytecode deployed at the addresses listed in the Smart Contracts Overview.

File format

Each .json is shaped:

{
  "name": "YCEToken",
  "abi": [
    { "type": "function", "name": "balanceOf", "inputs": [...], "outputs": [...] },
    { "type": "event", "name": "Transfer", "inputs": [...] },
    ...
  ]
}

Compatible with ethers v5/v6, wagmi, viem, web3.js, ape, foundry — every standard EVM tool consumes plain ABI arrays.
