## Abstract On the back of the positive feedback received from the community on the prototype deployed on testnet ([here](https://forum.pyth.network/t/express-relay-prototype/569)) and the completion of the security audit, this proposal is to implement the first instance of the Express Relay in production. To vote on this proposal, please proceed below: > **[Realms](https://app.realms.today/dao/PYTH/proposal/FCL7LsNooG5y5xPSJAmgTh5jTRQVPnZieoJRzgmkfKRz)** ## Rationale - DeFi protocols and DeFi users will benefit from the Express Relay primitive to reduce value leaking to block builders - Liquidation Searchers will benefit from broadening their access to liquidation opportunities - Pyth DAO will benefit from helping DeFi grow through additional revenue. Such revenue can be used to further Pyth ecosystem ## **Description** Express Relay consists of on-chain smart contracts and a off-chain user driven auction system infrastructure. DeFi protocols expose liquidation opportunities to Express Relay, and Searchers compete over the opportunity to liquidate through an auction system running off-chain. Liquidations are resolved in one-transaction within the same block. - this first instance will be on EVM chains (details in the implementation plan), with further deployments delegated to the Pythian Council, based on demand - the selection of ecosystem projects to provide a reliable infrastructure for the off-chain system and monitor their performance is delegated to the Pythian Council - Express Relay in production will continue to be oracle agnostic. Searchers and Protocols can use separate oracles to measure health factors and price the liquidation opportunities - Pyth DAO to earn 26% of the revenue collected by the Express Relay protocol. Such revenue is defined as the bonus paid by the winning Searcher for each of the liquidations processed through Express Relay. 4% is allocated to infrastructure providers and 70% is allocated to the DeFi protocols using Express Relay, inline with the design goal for DeFi to recoup most of the value ## **Implementation Plan** 1. DAO constitution changes to add Express Relay: [link](https://github.com/pyth-network/governance/blob/pip-er/docs/constitution/pyth-dao-constitution.md) 2. Security Audit report: [link](https://github.com/pyth-network/per/blob/main/audit-reports/pyth_per_audit_final.pdf) 3. Technical deployment: - Deploy contracts on mainnet with Pyth DAO as the sole admin of the express relay contract - Set the relayer via DAO proposal in the contract once the server is live on mainnet accepting new liquidation opportunities and conducting auctions - Conduct final tests with mainnet assets in small quantities to double check searchers and the relayer correct integration - Protocols upgrade to use express relay as their main entry point for their liquidations ---

Lets see what happens with this one… Not the most technical person over here but as far as I understand it looks like a thing that might affect pyth for the good ---

The proposal has passed with already 67.5% of the total staked tokens in favour. Many thanks to all Pythians for their continued participation in the future of the Network ---
