The SOST DEX is a non-custodial, cross-chain exchange built on the SOST protocol. There is no pooled custody and no order-book operator holding funds: trades settle as atomic swaps and offers are cryptographically signed by the party that makes them. The DEX never holds a seed or a private key — it only requests addresses and signatures from your own wallet.
How it works
RETIRED
Atomic-swap HTLC settlement. Each trade locks both legs in Hash-Time-Locked Contracts. The protocol is designed so that a party cannot successfully claim one leg without revealing the information required to claim the other; if settlement does not complete within the timelocks, the refund paths become available — so no counterparty can take one side and leave the other stranded. The SOST-side HTLC primitive has been live on-chain since block #16,000.
Signed offers
Signed-offer orderbook. Offers are discovered off-chain, each signed with a nonce and an expiry and validated bilaterally before anyone funds an HTLC. Placing or cancelling an offer never moves funds on its own; funds move only when you approve an HTLC reservation.
