What We're Building

Lightning is a decentralized network using smart contract functionality in the blockchain to enable instant, high volume transactions across a network of participants.

Instant Payments. Lightning-fast blockchain payments without worrying about block confirmation times. Security is enforced by blockchain smart-contracts without creating a on-blockchain transaction for individual payments.

Scalability. Capable of millions to billions of transactions per second across the network. Capacity blows away legacy payment rails by many orders of magnitude. Attaching payment per action/click is now possible without custodians.

Low Cost. By transacting and settling off-blockchain, Lightning allows for very low fees, which allows for emerging use cases such as instant micropayments.

Cross Blockchains. Cross-chain atomic swaps can occur off-chain instantly, enabling instant transactions between blockchains without custodial risk.
