What is the Address of Ethereum Contract
An Ethereum contract address is a unique identifier for a smart contract deployed on the Ethereum blockchain. It consists of 40 hexadecimal characters (0-9 and A-F), prefixed with "0x." For example, a sample contract address is 0x5b38da6a701c568545dCfcB03FcB875f56beddC4.
Steps to Find Ethereum Contract Address:
Check Etherscan:
- Go to etherscan.io and enter the contract name or bytecode in the search bar.
- Click on the "Contract" tab to view the contract details.
- The contract address will be displayed prominently at the top of the page.
Use Truffle/Web3:
- If you have access to the contract's Truffle or Web3 instance, you can use the
getAddress()
method to retrieve the contract address. For example, in Truffle:
const contractAddress = myContract.getAddress();
- If you have access to the contract's Truffle or Web3 instance, you can use the
Decode Transaction Receipt:
- When you deploy a smart contract, the transaction receipt will contain the newly created contract address.
- You can decode the transaction receipt using Etherscan or a web3 library.
- The contract address will be within the
logs

Check Contract Info:
- Some popular contract deployments, such as ERC-20 tokens, have dedicated websites or services that track their contract addresses.
- Visit these websites or use their APIs to obtain the correct contract address.
Interact with Blockchain Directly:
- Connect to an Ethereum node via RPC or WebSocket and execute a call to the
eth_getCode
endpoint, passing in the contract's address. - The response will include the contract's bytecode, which can be used to determine the contract's address.
- Connect to an Ethereum node via RPC or WebSocket and execute a call to the
Using Contract Address:
Interact with the smart contract using its address through various methods:
- Call its functions
- Send transactions
- Check its state
- Monitor its events
- Remember: Contract addresses are permanent and cannot be changed once deployed.
