Ethers.js – How to Create an Empty bytes or bytes32 in Ethers.js

ethers.js

I have a function that takes a bytes in solidity, and I want to pass it an empty bytes string without doing "0x000…", can I do this in ethersjs?

Best Answer

ethers.js has a Constants object that contains common values. One of those is ethers.constants.HashZero, which represents an empty bytes32 string.

There are more constants that you could read about here: https://docs.ethers.io/v5/api/utils/constants

For bytes, you would place an empty array ([]) as input in ethers.js. This is due to bytes being an array-based value.

Both Contract and ContractFactory objects have a method called connect that you can use to do this. See docs for Contract and ContractFactory.

Assuming you have an instance of the Signer object called signer, you can do something like this:

// Connect signer to contract and call the eat method on contract
contract.connect(signer).eat('Pizza');

Ethers.js – Retrieving the Provider Object from a Wallet Object

If your wallet is connected to the provider you should be able to get the providers object using wallet.provider

if you are trying to access the send function of the provider try creating a provider with JsonRpcProvider like:

create a provider with new ethers. providers.JsonRpcProvider(<networkUrl>)
but I guess this send function is used to fetch blockchain with raw data

if you are trying to send transaction using ethers provider directly. use provider.sendTransaction(<signedTransaction>) this will send your signed Transaction to blockchain
