Extending to ERC20's

[aodhgan]

Cool repo. In the case of (create2-based) SneakyAuction, at auction end you could potentially deploy preset bytecode to transfer/sweep an ERC20 to the highest bidder, and similarly for withdrawing to non-winning bids back to the original account. Is it possible/did you consider this and what if any difficulties did you foresee?

Thanks! Yes it's definitely possible and I did consider implementing ERC20 support, but it would add a bit of extra complexity for the balance proof –– you would need to perform some additional Merkle proof steps because ERC20 balances are in contract storage.
i.e. for ERC20 you'd be doing this instead of this
