so there are two "sides" to a cross-chain swap using The Compact or other resource locks the "fill side" is the chain where their output tokens are received the "claim side" is the chain where their input tokens are held & claimed by a filler

most development effort thus far for The Compact has focused on the claim side that's where the resource locks are, of course allocators (mediating resource locks) & arbiters (processing claims) both live on the claim side too but arbiters need to act on a cross-chain action

that's where Tribunal comes in it serves two core functions first, it protects fillers from settling a swap that another filler got to first second, it protects swappers from having claims processed from unrelated payments (like if you tried to do 2 cross-chain swaps at once)

this initial version of Tribunal is focused on fill side chains with sequencers that enforce priority ordering this just means the sequencer orders all transactions in the block by gas price it's the de-facto behavior on all OP-stack chains today, & Unichain will enforce this
