Introducing MEV support for Polygon
A lot has been written about miner-extractable value (MEV) so instead of reiterating the same information, let’s dive straight into the topic. We present…

Last month, we introduced the Flashbots architecture for Polygon through mev-bor. However, some validators expressed concerns over directly switching to mev-bor on mainnet. We thus introduce Loki, a Polygon MEV testnet dedicated to testing mev-bor and bundles sent via a compatible relay.
Current Polygon PoS architecture
Polygon PoS consists of two chains: Heimdall and Bor which work in tandem with each other.
Goals of the Polygon MEV testnet
The Polygon MEV testnet has been designed with the following goals in mind:
Architecture of the Polygon MEV testnet
Given the goals set above, it is clear that the Heimdall and Ethereum layers of the mainnet Polygon architecture are not strictly required. The Polygon MEV testnet consequently makes the following decisions:
In addition, to listen to MEV bundles, operators are required to run the Marlin gateway which connects to the Marlin relay. More information can be found in our docs here.
Source code for the testnet design can be found at https://github.com/marlinprotocol/loki. We hope the Polygon MEV testnet can be used to carry out interesting experiments in a lighter environment with different network parameters in addition to testing the stability of mev-bor.
