No. 01
Sealed Bids
EIP-712 signed bid; only commitment onchain. CRE stores the confidential message and finalizes after the blind deadline.
SILENTBID
Privacy-Focused CCA & Sealed-Bid Token Launches
A fork of Uniswap's Continuous Clearing Auction with sealed-bid confidentiality. You sign your bid with EIP-712; only a commitment goes onchain. Chainlink CRE stores and verifies the confidential message offchain, then finalizes and forwards bids after the blind deadline. No MEV sniping, fair onchain price discovery.

WHY BLINDPOOL
02 / Mechanism
HOW IT WORKS
EIP-712 signed bids, CRE workflows, and commitment-onchain. Privacy-first token launches.
Core Mechanism
Sealed-Bid CCA
Chainlink CRE orchestrates sealed bids. You sign with EIP-712; only the commitment is onchain. CRE verifies and stores the confidential message, then finalizes and forwards after the blind deadline.
Continuous Auction
Price Discovery
Bids integrate over time to determine a fair market-clearing price onchain.
Privacy Layer
No MEV Leak
Bid price and amount stay in CRE; only the hash is onchain. Bots and MEV cannot see your bid before close.
Liquidity
Pool Seeding
Auction outcome seeds a Uniswap pool. Permissionless, onchain.
Confidential Messages
CRE + EIP-712
Chainlink CRE and EIP-712 signed bids. Confidential HTTP keeps request/response private; CRE workflow enforces fairness and settlement.
Fair Access
Equitable Launches
More equitable token launch experience for all participants.
03 / Chainlink CRE
CRE WORKFLOWS
Three offchain workflows keep bid data private. Only commitments and settlement results touch the chain.
Step 01
Bid Ingestion
/api/cre/bidOffchain (CRE)
Verify EIP-712 signature, compute keccak256 commitment, store bid privately. Optional compliance check via Confidential HTTP.
Onchain
submitBlindBid(commitment) + msg.value escrow. Only the hash touches the chain.
Step 02
Finalize
/api/cre/finalizeOffchain (CRE)
Load all sealed bids, run uniform-price discovery (sort by maxPrice desc), compute clearing price and winner allocations.
Onchain
forwardBidsToCCA(clearingPrice, bids) — one batched transaction forwards all bids into CCA.
Step 03
Settle
/api/cre/settleOffchain (CRE)
Build settlement plan from allocations: winner payouts, excess-escrow refunds, loser full refunds.
Onchain
Execute transfers via compliant private calls. Individual payouts stay confidential.
Key point
Sensitive data (bid prices, amounts, identities, payout details) is handled only in CRE workflows. The chain sees only commitments and the batched forward / settlement results. In production, CRE + Confidential HTTP ensures API keys and bid data never appear onchain or in public logs.
04 / Principles
BLINDPOOL VALUES
SEALED BIDS
You sign your bid with EIP-712. Only a commitment is onchain; CRE stores and verifies the confidential message. No leakage to MEV or snipers until the auction closes.
FAIR DISCOVERY
Continuous, onchain price discovery. Market-clearing outcome seeds liquidity.
PRIVACY BY DESIGN
Chainlink CRE and confidential EIP-712 messages. Bid data stays offchain; CRE workflow finalizes and forwards. Cryptographic confidentiality, onchain enforceability.
EQUITABLE LAUNCHES
More equitable token launch experience. Built on Uniswap's CCA, extended with CRE for privacy.
