Built by Sarthak Biswas

Every trade on-chain is public

  • Investors panic-sell on unrealized losses
  • Your strategy alpha decays because it is visible

Umbra makes trading private

Three primitives from the Umbra SDK that change everything.

Encrypted Balances

Portfolio value hidden via encrypted token accounts. On-chain observers see ciphertext, not amounts.

Confidential Transfers

Trade amounts invisible on-chain. Swap SOL/USDC without revealing position size.

🔑

Viewing Keys

Scoped auditor access via Poseidon-derived keys. Prove solvency without exposing strategy.
