Making DeFi Truly Cross-Chain
summary
Proposes a single unified auction to cut solver capital needs by matching and batching cross‑chain intents into executable bundles, claiming a combinatorial batch auction where multiple solvers win non‑overlapping subsets and execute in parallel. Uses an on‑chain settlement plus an account ledger whose validators co‑sign balance updates, and an insurance fund (CCTP v2 style) for optimistic finality. Leverages standing limit orders and peer matches because 80% of crosschain volume touches five tokens, versus solver capital example of $10M to cover 10 tokens × 10 chains for $100k trades.
