Loopring Exchange has listed KEEP, the token of the Keep Network, a privacy layer for Ethereum.

Right now on Loopring Exchange, the trading pair KEEP/USDT is supported.

Users can trade the token from this highly anticipated project in a self-custodial fashion, and at the highest speeds and lowest costs of any Ethereum DEX.

Keep is an ERC-20 token, with the contract address of https://etherscan.io/token/0x85eee30c52b0b379b046fb0f85f4f3dc3009afec.

The KEEP token is quite new, having only been deployed in late April. As such, Loopring Exchange is one of the only venues to trade the asset. To our knowledge, KEEP is only on Uniswap in terms of other DEXs.

About Keep Network

The following information is taken mainly from Keep’s ‘primer’ doc which can be found on their website.

The Keep network features off-chain containers for private data called keeps that give smart contracts deep interactivity with private data without compromising transparency or auditability.

Protected by secure multi-party computation (sMPC), keeps are used to securely encrypt private data. Keep is one of the first production-ready sMPC systems for distribution on the public Ethereum blockchain.

For anonymity and flexibility beyond what multi-signature can offer, Keep builds on Threshold Elliptic Curve Digital Signature Algorithm (T-ECDSA) for keep signers. ECDSA is a cryptographic algorithm that allows a single signing key to be backed by a group of signing nodes, ensuring only rightful owners can spend their funds. Specifically, T-ECDSA leverages zero-knowledge proofs to provide confirmation of transactions and signers without exposing the information or players themselves.

About the KEEP Token

Keeps must be highly available, robust against data loss, and maintain both confidentiality and data integrity. The Keep network’s operating system is driven by incentives, underpinned by a staking-based economic consensus mechanism.

Used for staking, the KEEP token is a type of utility token, sometimes called a ‘work token,’ that is required for participation on the network. Node operators and keep providers are required to prove and lock up their holdings; to “stake” their network cryptocurrency. Staking incentivizes these players to run a reliable system by rewarding them with fees for their work.


Keep Network is part of the group who designed and developed the open source tBTC project — a trustless method of porting BTC to Ethereum. tBTC launched recently, with the first TBTC having been minted on mainnet just yesterday. As you may imagine, tBTC has thoroughly interested us at Loopring, as it provides a way for our users to trade BTC on Ethereum, while maintaining non-custodial guarantees throughout. We are among the launch partners, and will have news on TBTC trading on Loopring Exchange next week.
