FIO Handle Resolution

Image Added

• Overview

  • When user has the FIO Snap installed, FIO Handles will be resolved inside MetaMask on send.

• Manifest spec - this ensures OnNameLookupHandler receives any data typed for any chain

"endowment:name-lookup": {}

• Look-up logic

  • Verify that the string received matches the FIO Handle format

  • Convert chainID to chain_code and token_code - DEV NOTE: mapping static file TBD, e.g. eip155:1 is chain_code: ETH, token_code:ETH

  • Execute /get_pub_address

  • Return public address

  • Example OnNameLookupHandler

export const onNameLookup: OnNameLookupHandler = async (request) => {
  const { chainId, address, domain } = request;

  if (domain) {
    const resolvedAddress = '0xc0ffee254729296a45a3885639AC7E10F9d54979';
    return {
      resolvedAddresses: [{
        protocol: 'FIO Handle',
        resolvedAddress: resolvedAddress,
        domainName: domain,
      }]
    };
  }

  return null;
};
