• 1adb83804d5f6c3f36d5f293de88532330d52dc7 Thanks @jxom! - Breaking (viem/tempo): chainId is now required when signing access key authorizations with signKeyAuthorization. It is recommended to use client.accessKey.signAuthorization instead for inferred chain ID.

  import { client } from './viem.config'
  import { Account } from 'viem/tempo'
  
  const account = Account.from({ privateKey: '0x...' })
  const accessKey = Account.fromP256(generatePrivateKey(), {
    access: account,
  })

  + const keyAuthorization = await client.accessKey.signAuthorization({
  +   account,
  +   accessKey,
  + })
