Aspens Documentation

Aspens is a non-custodial crosschain trading protocol. The first service built on it is the Aspens Market Stack (AMS) — an orderbook + matching engine with on-chain trading contracts on every connected chain.

Funds stay under user control: deposits sit in per-chain trading contracts (MidribV2 on EVM, the Midrib Anchor program on Solana), orders are authorized by gasless signatures, and every fill settles natively on both chains involved.
