As a developer
I want Sygma erc20 transfer to behave as all other bridges
So that I can integrate it as a drop-in solution.
Background
Right now, sygma bridge ux is weird as you approve tokens to the erc20 handler and potentially to the fee handler and then call the bridge contract. Which is sketchy at best.
Details
Create ERC20 adapter to be usability proxy where you will approve your tokens (ideally upgradable so that we can fix it in case a vulnerability is found) and on the same address. That proxy will then approve tokens to fee handler and erc20 handler.
