Loopring is a protocol for building decentralized exchanges. Besides the
protocol smart contracts, Loopring also offers a collection of open-sourced
software to help you build decentralized exchanges.
Non-custodial & On-chain settlement
Loopring does not require users to send tokens to any party for custody.
Tokens always remain in users' blockchain addresses during the entire trading/transaction
life cycle. Loopring orders do not lock users' assets, which means users
can transfer tokens around even after orders have been submitted - Loopring
will automatically adjust order amounts during settlement. Loopring protects
users from threats such as exchange bankruptcies and hacking.
Loopring's generic design ensures it may be deployed on top of any public
blockchain that has smart contract support. It can also be integrated into
blockchains as part of their native codebase. We have deployed Loopring
on the Ethereum mainnet, and have deployed an implementation on the NEO
Loopring provides higher liquidity and price improvement by matching orders
in the form of order-rings. Each ring may consist of 2 to 16 orders, and
tokens are transferred atomically in a circular manner during ring settlement.
Loopring is designed to provide matching-as-a-service, and its orders
are unidirectional and do not differentiate takers and makers. Loopring's
order-rings generalize trading pairs and enable a built-in mechanism for
Loopring orders do not hold any tokens and can thus be shared with as
many relayers as possible. We encourage order sharing to speed up order
matching and avoid single points of failure.
With order sharing, multiple relayers can form a consortium for building
a shared liquidity pool to compete with established exchanges. The overall
liquidity of Loopring-powered exchanges will be less fragmented.
Our patented "Dual Authoring" technology prevents orders and rings from
being stolen by any middlemen or blockchain miners without binding orders
to any dedicated relayers. The decoupling of orders from relayers makes
orders genuinely sharable.
Building on Loopring
Loopring is an open-sourced and transparent protocol for building decentralized
exchanges. Also, DEXs and wallets building on top of Loopring Protocol
can combine off-chain order sharing and on-chain settlement. The following
products all integrate with Loopring Protocol to provide digital assets
