zkSync & MYKEY

  1. Data format

We decide to accept your sugesstion with a few modification.

bytes32 salt = keccak256(abi.encode(someData, zkSyncPubKey));

See https://github.com/clar/keyid-eth-contracts/commit/b672b3909fed8580688980fd620f30484deb2b65

  1. About SDK libraries

Actually we implemented web3js standard interface in our own browser environment, and we use golang to self-implement the specific web3 functionality against on MYKEY, then golang part are packaged into C++ library, then using by both on ios and android as a framework lib.
So for ethereum supporting, we provide javascript sdk to handle it for 3rd-party application on client side.
For zkSync, the first choice for us is go sdk or source code provided for both side, it only needs one code copy for multi platform to us. For sure, Java sdk on Android and Swift sdk on ios also work for us.

  1. We need a test network to test(Currently we're on Ropsten)
