open-sourced another building block on the path to cross-chain swaps: a reference implementation of a minimalistic server-based allocator for The Compact it's called Smallocator š¤ https://github.com/Uniswap/smallocator if you're wondering "what the hell is an allocator" then read on ā

so the way that The Compact works is that you deposit into resource locks when you do, you choose an allocator for that lock then when you create a compact (e.g. a request to take some action) they make sure you're not double-spending & "attest" that the compact's good to go

arguably the most straightforward allocator would be a purely onchain contract to fill a cross-chain swap, you'd call this contract, it'd check your balance and your pending compacts, and reserve the tokens for you for a little while but this is slow, pricey, and not private

another approach is to run it in a server like Smallocator granted, fillers and solvers are counting on the server not to let users double-spend but it's fast & basically free it also delays revealing info about the cross-chain swap or other action to help avoid getting š„Ŗ'd

this codebase is meant to serve as a reference if you want to learn more about allocators you can click around on the frontend (link on the readme) as well as with the API (the "main course") it's also a good starting point if you're looking into running an allocator yourself!

one final caveat here: this is really not meant for production use at all if you're working on chain abstraction & curious about how The Compact works i highly encourage you to give Smallocator a whirl much more to come; this is just another small step š¤
