This documentation is work in progress and web3. You can find the current documentation for web3 0. The web3-eth package web3 ethereum mistake you web3 ethereum mistake interact with an Ethereum blockchain and Ethereum smart contracts.
All Ethereum addresses returned by functions of this package are returned as checksum addresses. This means some letters are uppercase and some are lowercase. Based on that it will calculate a web3 ethereum mistake for the address and prove its correctness.
Incorrect checksum addresses will throw an error when passed into functions. If you want to circumvent the checksum check you can make an address all lower- web3 ethereum mistake uppercase. Contract see the Contract reference documentation. Iban see the Iban reference documentation.
