Requirements

Be sure to comply with the requirements while building connectors for better compatibility.

• Import common files from contracts/common directory.

• The contracts should not have selfdestruct().

• The contracts should not have delegatecall().

• Use uint(-1) for maximum amount everywhere.

• Use getEthAddr() to denote Ethereum (non-ERC20).

• Use address(this) instead of msg.sender for fetching balance on-chain, etc.

• Only approve() limited amount while giving ERC20 allowance, which strictly needs to be 0 by the end of the spell.

• Use getId() for getting value that saved from previous spell.

• Use setId() for setting value to save for the future spell.
