The zero-knowledge validity proofs will become canonical across the OP stack.
Ethereum Layer 2 Optimism is partnering with Succinct as its first zero-knowledge (ZK) proving provider, in order to provide instant and real-time withdrawals from the L2, according to an announcement shared exclusively with The Defiant.
The move makes Succinct Optimism’s first official ZK partner, and by leveraging Succinct’s proof system, users can off-ramp capital from Optimism to any other chain in a timely fashion, as opposed to the bridge’s traditional, multi-day wait time.
By accelerating the bridge time from Optimism, large on-chain operators such as market makers or treasuries, can move capital quickly without having to rely on a third party bridging solution.
In addition to its withdrawal time upgrade, Optimism is also working towards a larger ZK proof infrastructure launch on the chain, which will allow teams building across the OP Stack to upgrade to ZK validity proofs “seamlessly” per a release shared with The Defiant.
Karl Floersch, the co-founder of Optimism commented on the news:
“Succinct offers one of the most trusted proof systems in the industry, securing billions of dollars in TVL. We’re excited to bring validity proofs to the Superchain as we focus on fast, cost-effective scaling for Optimism and our partners in 2026 and beyond.”
“We’re honored to partner with Optimism to bring ZK to the Superchain, starting with OP Mainnet. As rollups consolidate around ZK, Succinct is building the proving infrastructure the ecosystem can rely on,” said Uma Roy, CEO and co-founder of Succinct.
The news comes shortly after Optimism unveiled OP Enterprise — a new chain deployment suite for enterprise clients who are looking to build their own native blockchains.
