Documentation for the propAMM settlement infrastructure Biconomy is bringing to Arbitrum: chain-agnostic EVM contracts, built and load-validated on a public L2 testnet, designed to scale propAMM volumes on Arbitrum One.
docs/propamm-on-arbitrum.md: partnership context. The problem propAMMs hit on permissionless L2 deployments, what we built to close the dominant toxic-flow vector at the contract layer (ERC-8211 freshness predicates developed with the Ethereum Foundation), why Arbitrum is the right operational home (250ms blocks, private-mempool sequencing, an evolving ordering-policy surface), MM commitments, unit economics.docs/transaction-ordering.md: how PropAMM would use new transaction-ordering primitives on Arbitrum. A commit lane scoped to price commits, application-declared ordering as a standing rule, why ordering matters for Arbitrum, and open questions for the Arbitrum team.
