About Connext

At Connext, our goal is to build the cross-chain routing and micropayment layer of the decentralized web. Vector sits on top of Ethereum, evm-compatible L2 blockchains, and other turing-complete chains, and enables instant, near free transfers that can be routed across chains and over liquidity in any asset.

Task

The overall goal of this task is to create a gRPC-based communication layer on top of Vector server-nodes. Currently, the server nodes have an HTTP REST interface for communication. This is okay for user-node actions, but in a high-throughput microservice architecture, we need something more performant and flexible.

The Vector router is a microservice that is designed to run in a stack with a server node. The router currently interacts with the server node through HTTP requests. We would like to enable bidirectional communication between the server node and the router, which will be easily enabled through gRPC.

Requirements

• Create gRPC server in server-node that implements the API that is defined by the endpoints here: https://github.com/connext/vector/blob/main/modules/server-node/src/index.ts
• Create a gRPC client in router that can communicate with the server-node.
• Create gRPC server in router which can push events back to the server-node.
• Make sure protobuf specs have corresponding Typescript types (even better if they are automatically generated!).
• Follow the code style of Vector repo.

Bounty

A total of $200 DAI is allocated to this bounty.
