How to convert address type to bytes32 via web3?

Question

I have contract which require input in bytes32, so I need convert address to bytes32, but no see this method in web3.

Answer 1

Ethereum addresses are 20 bytes, so you convert hex address to bytes and then pad it to 32 bytes from left.

web3.utils.padLeft(web3.utils.hexToBytes(yourAddressString), 32);

Answer 2

If you read the PadLeft documentation, you'd see that you don't need to do any conversion. You simply should do a web3.utils.padLeft(address, 64). Given that you want bytes32, that is a total of 64 hex digits, you just need to fill the difference in 0s for in order to have 64 digits.
