T-ECDSA - Local Testing. Am I doing something wrong

Hi @skilesare

I don’t know about any Motoko examples, but for Rust there are several resources that could maybe help you:

  1. basic_ethereum example
  2. ICP alloy from @kristofer

Regarding the RLP encoding, could it be that the length of the list was forgotten in the RLP encoding (just a guess)? For debugging purposes I would suggest to test your implementation against some known test vectors.
