Aspens Documentation

Aspens is a non-custodial multichain 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 (MidribV3 on EVM and Tron, the Midrib Anchor program on Solana), orders match instantly and cost no gas to place, and every trade settles natively on the chains involved — no bridges, no wrapped assets.
