Discussion

• Allowances problem with multiple transfers. See #97
• Fees included in the eth-connector. See here
  • Pros: makes a user interaction with the bridge condensed into a single transaction; provides a safe way for a user without NEAR account to transfer ETH directly into the EVM.
  • Cons: relaying logic is not as a part of this connector but rather separate thing; relaying fee fixed in the beginning of the transfer might not account for the the rate slippage for 7 min
  • Decision: to discuss more. See the discussion here
