Non-CustodialFrequently Asked Questions
Everything you need to know about Cliff Protocol
Cliff Protocol is a privacy-preserving marketplace for vesting tokens. Sellers can list their locked tokens from standard vesting contracts, and buyers can pool funds to purchase them at a discount. All transactions use stealth addresses to protect participant identities.
When you contribute to a pool, you generate a one-time stealth address derived from your private spending key. Tokens are delivered to this unique address that only you can access. This breaks the on-chain link between your main wallet and your purchases.
If a pool fails to reach its minimum threshold by the funding deadline, all deposited USDC is automatically refundable. You can withdraw your contribution at any time after the deadline passes.
Yes. The protocol uses Oasis Sapphire's confidential computing to encrypt deal data, and stealth addresses ensure token deliveries cannot be traced back to your wallet. Neither sellers, other buyers, nor blockchain observers can identify you.
Cliff Protocol works with any ERC-20 token held in a standard vesting contract (like OpenZeppelin's VestingWallet). The seller must be the beneficiary of the vesting contract and approve the protocol for token transfers.
As tokens vest in the seller's contract, the protocol agent automatically executes deliveries. Tokens are distributed pro-rata to all pool contributors based on their share, delivered directly to their stealth addresses.
The protocol takes a small percentage of each successful deal as a fee. The exact fee structure depends on the deal grade selected by the seller, with lower grades (faster upfront release) having slightly higher fees.
