Infrastructure & Audits
Shard is built on top of Polymarket's open-source infrastructure, with a custom application layer handling the workspace, privacy routing, wallet management, and widget system.
How It Works
Shard connects directly to Polymarket's CLOB and data API. Orders are signed locally in your wallet and submitted through Shard's Privacy Layer — the platform acts as an interface, never a custodian.
All wallet interactions are handled via Gnosis Safe, giving users full self-custody with multi-wallet support. Deposits flow directly from your wallet to Polymarket — Shard has no access to funds at any point in the flow.
