Metis Hybrid Rollup Launches on Devnet, with post-quantum proof pathway under development
BlockBeats reports that November 11，Metis announced that its Hybrid Rollup has launched on Devnet. The solution introduces validity proofs into Metis's existing optimistic Rollup architecture, shortening withdrawal wait times by verifying execution results onchain.Metis first proposed the design at ETHDenver in 2023 March. The original proposal aimed to reduce the withdrawal waiting period from 7 days to hours.Metis said the upgrade covers components: combining optimistic challenges with Ziren-based validity proofs (Ziren is an open-source ZKM developed by the zkVM project) and support in the decentralized sequencer (DSeq) for ML-DSA post-quantum signatures. The Devnet is designed for cryptographic agility, with the codebase supporting both the ECC and PQC pathways. Initially, only ECC will be enabled, followed by a module-by-module transition to post-quantum cryptography.
The testnet is scheduled to launch in 2027 Q1 to demonstrate the operation of both the ECC and PQC verification pathways and further test the upgraded Hybrid Rollup architecture.
In addition,Metis published a draft for public discussion proposing to convert the OVM Token into a native asset to align more closely with a standard EVM execution environment. The draft has not yet received governance approval, and the snapshot block and timeline remain undetermined.

Key points
01
According to BlockBeats,Metis announced that Hybrid Rollup has launched on Devnet, introducing validity proofs into the existing optimistic Rollup architecture.
02
Metis first proposed the design at ETHDenver in 2023 March. The original proposal aimed to reduce the withdrawal waiting period from 7 days to hours.
03
The upgrade combines optimistic challenges with Ziren validity proofs; Ziren is an open-source ZKM developed by the project zkVM。
04
The upgrade includes support in the decentralized sequencer DSeq for ML-DSA post-quantum signatures. The codebase supports both the ECC and PQC pathways, but initially only ECC will be enabled, followed by a module-by-module transition.
05
The testnet is scheduled to launch in the first quarter of 2027 to demonstrate the ECC and PQC verification pathways and further test the upgraded architecture.

AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
This launch is on Devnet. The solution combines validity proofs with the existing optimistic challenge mechanism, aiming to shorten withdrawal wait times by verifying execution results onchain. Code support for post-quantum cryptography does not mean the relevant pathway has already been enabled: initially, only ECC，ECC is enabled. A demonstration of both the PQC pathways is scheduled for the subsequent testnet. The token conversion remains a discussion draft.
Why it matters to readers
Key points to watch are whether withdrawal wait times can actually be shortened and the results of subsequent testing of the post-quantum verification pathway. The current report provides Devnet progress and future plans.
The Devnet launch should not be interpreted as completion of a mainnet upgrade, nor should the original design goal of withdrawals within hours be treated as an achieved result. The token conversion proposal has not necessarily been approved.
Risks and unknowns
The original report did not provide a mainnet deployment date or test results for actual withdrawal wait times.
The post-quantum pathway is not enabled initially, and the specific timing of the subsequent module-by-module transition has not been clarified.
2027 The testnet launch in the first quarter remains planned, and results from testing the verification pathways have not yet been provided.
OVM Token conversion draft has not yet received governance approval, and the snapshot block and implementation timeline remain undetermined.
