SYLPHY
Private trading for autonomous agents
INTENT. POLICY. AUDIT.
EVERY TRADE YOU MAKE IS PUBLIC
Right now, when you buy or sell a token on Uniswap or any DEX, your order is visible before it executes — bots can frontrun your trade, and your intent, amount, and strategy are exposed.
Copy traders follow your moves. Bots frontrun your orders. Competitors see your workflow. You lose money just by being visible.
Sylphy solve this. Your order intent is encrypted before execution, processed inside a sealed TEE environment, and settled on Base with an encrypted audit proof.
No account needed, No identity check, No minimum amount, start trading with encrypted intent.
BUILT FOR THE AGENTIC TRADE
ENCRYPTED INTENT
Your trade order, direction, amount, and CA are encrypted instantly in your browser before ever hitting the network.
PEDERSEN COMMITMENTS
On-chain trade amounts are completely hidden behind math, preventing front-runners from viewing order sizes.
TEE ENCLAVE MATCHING
Orders are matched confidentially off-chain inside secure enclave hardware with timing jitter to stop timing attacks.
TEE-SIGNED ZK SETTLEMENT
Settlement only executes on-chain after verifying ZK proofs and enclave hardware signatures — ensuring every trade is cryptographically proven before it settles.
x402 API GATEWAY
AI agents and third-party APIs pay per-request in USDC on Base via the x402 Protocol, while web interface users trade 100% free.
ENCRYPTED AUDIT TRAILS
Every settled trade generates an encrypted audit summary. Authorized agents and owners can retrieve it on-demand via the x402 pay-per-request API — no central gatekeeper required.
PRIVATE BY DESIGN
Final settlement on Base stays public and verifiable. Everything around it — your intent, strategy, and workflow — stays sealed.
