Verifiably fair perpetuals
A high-performance perpetual DEX with a deterministic, replayable matching engine. Self-custody collateral, on-chain vaults, and public liquidations — trade with confidence.
Built to be trusted
Fairness you can check, custody you keep, and risk that clears in the open.
Verifiably fair
Every fill is produced by a deterministic matching engine and replayable from the write-ahead log. The state root is committed on-chain — trust the math, not the operator.
Self-custody
Your collateral sits in an on-chain vault and you sign every order yourself. Pactol never holds your keys or moves funds without your signature.
On-chain vaults
Open a copy-trading vault or follow a leader's. Shares are minted at a NAV published on-chain from the engine's audited equity, and are redeemable on-chain once the 1-day deposit lockup has passed.
Public liquidations
Under-margined positions are closed by the engine itself: an on-book partial close first, then the protocol backstop and ADL. Every step is a sequenced, replayable rule — no dark backstop.
