Contextualizing getContractAbi

  • getContractAbi takes the address of a verified contract and returns the complete ABI. It will return null if the contract is not verified.

If you’re unsure whether a given contract is verified, Etherscan displays verification status on the Contract tab of smart contracts

Check it at: https://etherscan.io/address/YOUR_CONTRACT_ADDRESS#code
