Relay is an App and API that enable instant, low-cost bridging, swapping, and cross-chain calling. The API allows a user to pay for transactions on any chain with currency from any other chain. Additionally, the API aggregates swap routes across chains, meaning a user can pay for for swaps and cross-chain transactions by leveraging the best available liquidity directly via the API.

Relay is designed for both same-chain and cross-chain excecution, and leverages the Relay Protocol to minimize gas costs and execution latency across chains. The speed and low cost makes the API ideal for price & time sensitive applications, such as payments, bridging, nft minting and gas abstraction, and cross-chain swaps.

Relay features the following key properties:

  • Fast: Cross-chain transactions confirm in seconds.
  • Cheap: Designed to reduce gas and capital costs, meaning the best possible price for users.
  • Chain-extensible: Easily extensible to any new chain. We currently support Bitcoin, Solana, and 44+ EVM chains, including appchains.
