The Layerswap V8 protocol is a peer-to-peer system for bridging/swapping crypto assets from one blockchain network to another. The protocol is implemented as a set of persistent, non-upgradable smart contracts, deployed to all supported networks.

  • V8 is built on top of an improved version of Atomic Swaps, which allows two parties to exchange assets trustlessly across different chains. Specifically, the two parties are the user and the liquidity provider. Users send requests to liquidity providers, who fulfill them using Atomic Swaps. There are no third parties or gatekeepers; the security of the exchange is fully ensured by the cryptographic protocol.
  • Permissionless on-chain Discovery registry, where new LPs and new networks can register.
  • Permissionless addition of new networks/assets and liquidity providers.
