Metis Hybrid Rollup Launches Devnet, Withdrawal Wait Time Reduced to Hourly Levels

Metis has announced that its Hybrid Rollup is now live on Devnet, introducing validity proofs into the existing optimistic Rollup architecture to shorten withdrawal wait times through on-chain verification of execution results. This design was first proposed in March 2023 at ETHDenver, aiming to reduce the withdrawal wait period from 7 days to hourly levels. The upgrade includes two components: combining optimistic challenges with validity proofs based on Ziren, an open-source zkVM developed by the ZKM project, and support for decentralized sequencer DSeq for ML-DSA post-quantum signatures. The Devnet employs a cryptographic agility design, with the codebase supporting both ECC and PQC paths, initially enabling ECC and later transitioning module by module to post-quantum cryptography. The testnet is planned to launch in the first quarter of 2027, demonstrating the operation of both ECC and PQC verification paths and further testing the upgraded Hybrid Rollup architecture. Additionally, Metis has proposed a public discussion draft for converting OVM Tokens into native assets, which has not yet been approved by governance, with the snapshot block and timeline to be determined.
