A place for talking about the Ethereum Virtual Machine on Farcaster.

In writing Solidity smart contracts, what's the best way to batch transfer ETH to a large group of recipients?

yea was trying to see if I could skip the withdraw step and just directly send ETH, but seems like it might be risky

There is no easy way without consuming lots of gas ⛽️
Pull-based approach, using a Merkle Tree is the safest and cheapest but you have to compromise on UX, users must claim their allocation.

Create a payable function that is predicated with onlyOwner and has multiple address parameters and uint256 for token amount (you could also use a structure for tuples if you know how). Then use the transfer function to disburse the funds.
