This repository contains the Relayer that allows the Solana Gateway to communicate with Axelar Amplifier API.
The relayer is built of composable plug-n-play items, called components, which can communicate with each other via channels and (optionally) persist in their storage.
- Solana Listener: Receives transaction log data from Solana using WebSockets. Listens to Gas Service and the Gateway.
- Solana Event Forwarder: Parses transaction logs into events and combines the Gas Service events with the Gateway logs. Forwards them to the Amplifier component.
- Rest Service: Receives an off-chain payload from the end-user, combines it with an on-chain event and sends it to the Amplifier API.
- Solana Gateway Task Processor: Receives tasks from Amplifier API and composes transactions to interact with the Gateway and the destination contract.
- File-based storage: Simple file-based memory-mapped buffer storage for tracking metadata for different components.
- Retrying Solana HTTP Sender: Solana RPC client wrapped with a retrying mechanism to account for Solana node fluctuations. Used by all components that require Solana RPC access.
- Effective TX Sender: Evaluate the necessary compute budget and unit price and prefix this new instruction inside the transaction.
- Gateway Gas Computation: The Axelar Solana Gateway has a multi-computation model; therefore, figuring out how much money was spent on a single gateway action needs to be summed together based on all the actions that the relayer did across many transactions.
- Solana Contracts: The Solana on-chain contracts and home to some of the utillty crates used in this repository.
- Relayer Core: All Axelar-related relayer infrastructure. Used as a core building block for the Solana Relayer. The Axelar-Starknet and Axlelar-Aleo relayers also use it.

We are engineers. We contribute to various ecosystems by building low-level implementations and core components. We work on several Axelar and Solana projects, and connecting these two is a fundamental goal to achieve cross-chain execution.
