Relayer

Relayer is responsible for retrieving data and proof of other chains

Relayers act as intermediaries between the source chain and the destination chain. Their main functions are as follows:

• Monitor and receive query requests emitted from the Gateway Contract on the source chain

• Obtain proof based on the query requests

  • Use eth_getProof to obtain account proof and a storage proof

• Send the proof as a transaction to the Gateway Contract on the source chain

Today, Futaba operates its own Relayer. In the future, we will provide a module to customize Relayer more easily to support Proof of Block Hash when using Konoha, and aim to build a Permissionless Relayer.

The current Fee for Relayer can be found in Estimate fee.
