sending eth directly to buyusdc.eth gets you more usdc and saves about three dollars on gas versus swapping on any of the popular routers on mainnet. This is efficiency at a per-lego level. Zwaps should be simple.

the trick here is modifying code to match the tokens and pool on each chain

I write. I code. I law. Building ægentic software nani.ooo ʞK kali.gg. fmr. consensys, sushiswap.

cool idea. Yeah, I think that can be done as a batch relay. Shall cook

Love it! Can this extend it into crypto dust sweeper? 

I send all my dust tokens to one address and you take a cut and send back as eth?

yeah, moneypipes (no longer running, but loved the UI). 

bridge variant isn't hard. Simplest and most trustless I think would be to just complete the swap on L1 and then call `depositTo` (etc) of that output token for the benefit of the eth sender on the bridge. I will work on that a bit later.

Very cool. Reminds me of one a bit ago. Pipes/tubes can’t remember the name but same idea. I think they also a had a bridge version. Where you could send manner ETH and get L2 ERC-20. Don’t believe it’s around anymore. 420 $degen.

nice lol. Adapting any output is easy.

What you want to check is basically pool "token order". In terms of what you want to get out of sent ETH. Just affects the swap params (whether `zeroForOne` sent to pool is "true" or not) and the fallback receipt amount.

If you have any tokens in mind, I can whip a gist quick.

i just tried this and it's amazing. haven't read the contract yet - how easily does this generalize to other erc-20s?
