Relayers

Get Started

  • Run a Custom Relayer


    This section guides you through developing your own custom off-chain relaying service, giving you greater control and flexibility than using Wormhole-deployed relayers.


    Benefits of running your own relayer:

    • You can add logic to customize the delivery of messages
    • You can perform off-chain computations resulting in optimized gas costs


    Requirements for running your own relayer:

    • You are responsible for developing and hosting your relayer
    • You are responsible for paying target chain fees
    • You are responsible for the liveness of your relayer
