Parasol
The engine that makes Solana the on-chain perps machine.
Parasol is an execution engine for on-chain perpetual futures on Solana, using zero-knowledge proofs to verify off-chain computation. Order matching, deposits, and withdrawals are processed off-chain, with resulting state commitments settled on Solana as SPL tokens. The engine provides dedicated blockspace per application and deterministic transaction ordering, targeting 25 millisecond order execution.
