1. KMS Recovery Path on Sui (15 May 2026)
Overview: This update introduced an additional recovery method for Marlin's Key Management Service (KMS). It provides a backup path powered by the Sui blockchain, operating independently from the existing system.
The enhancement integrates Seal on the Sui Network, with enforcement logic handled by Sui smart contracts. This creates a redundant, on-chain verified recovery option for critical keys, strengthening the protocol's fault tolerance without altering its core relay mechanics.
What this means: This is bullish for POND because it makes the network more resilient and secure by adding a verifiable backup system. It demonstrates active development focused on enterprise-grade security and expands Marlin's interoperability with other leading blockchain ecosystems like Sui.

2. MEV Support & Gateway Updates (September 2021)
Overview: This older suite of updates brought Maximal Extractable Value (MEV) functionality to the Polygon network and upgraded communication gateways. It allowed validators to earn extra income and protected users from front-running.
The engineering work included repurposing the mev-inspect-py tool for Polygon, updating Ethereum and Polygon gateways to the eth/66 protocol, and adding cancellation features to the bridge. These were significant technical improvements for their time.
What this means: This was bullish for POND at the time, as it expanded the protocol's utility to a major Layer 2 network (Polygon), creating new use cases and potential fee revenue. It showcased Marlin's adaptability to support emerging blockchain needs like MEV protection.
