Description

21X Exchange is a regulated trading and settlement system for tokenized financial instruments. The system uses a central limit order book implemented via smart contracts on the Polygon proof-of-stake blockchain to enable issuance, listing, multilateral trading, and atomic settlement of DLT financial instruments including tokenized equities, bonds, and fund tokens. A compliance layer enforces KYC, AML, and participant whitelisting in accordance with MiFID II and MiCAR requirements. Participants connect through self-custody wallets, REST API, WebSocket API, or smart contract interface. Settlement occurs atomically within the same blockchain transaction as order matching, eliminating counterparty risk.
