Dear Lido community,

Manifold Finance will soon be transitioning to a new relay codebase that we believe provides several advantages, described below. We have been running the relay, called **mev-freelay** , on Goerli for several months without issue, and will have a security audit conducted in the coming weeks. After this we will transition to mev-freelay on mainnet.

We’ll post an update after the audit is completed, and are happy to answer any questions in the meantime.

**Principal advantages of mev-freelay:**

- Use of a single process and embedded bbolt database for persistence, leading to lower latency and resource usage for operations

- Automatic archiving of submitted payloads to S3, which keeps the operation database length approximately constant

- Simple backup and restore process

It’s great to see a new relay codebase and open source too!
