A place for developers to talk about building on Farcaster.

ChatGPT failed me on this question so I'm asking here:

I'm trying to use Viem to recreate a solidity function that computes an address. Viem has abi.encodePacked but no abi.encode. How do I do the abi.encode part of this?

Got it! For anyone who stumbles on this in the future, here is the solution:

gigameshmusic.com | fc.hot100.xyz (@hot100) | farther.social /farther | formerly optimism.io & sound.xyz

That's how the outer abi.encodePacked call works, but the inner abi.encode is something different. It apparently adds padding. Web3.js has a function for it but I'm trying to avoid importing another library.

I think just pass in the raw parameters without all the abi? Just the types 

encodePacked(
  ['address', 'string', 'bytes16[]'], 
  [
    '0xd8da6bf26964af9d7eed9e03e53415d37aa96045', 
    'hello world',
    ['0xdeadbeefdeadbeefdeadbeefdeadbeef', '0xcafebabecafebabecafebabecafebabe']
  ]
)

What about https://viem.sh/docs/abi/encodeAbiParameters.html?

I’m a builder looking for the next challenge. 

That's used when the variables have names, but thank you.
