Optimism, the Ethereum scaling network behind the OP Stack framework, has partnered with Succinct, a provider of zero-knowledge proof infrastructure, to bring validity proofs to its core architecture for the first time.
The integration designates Succinct as the preferred ZK proof provider for Optimism’s ecosystem. Transactions will be verified cryptographically rather than through the dispute-based system that optimistic rollups traditionally use, removing the multi-day waiting period currently required for withdrawals.
The upgrade, branded OP Succinct, will first deploy on OP Mainnet before becoming available to other chains built on the OP Stack.
Withdrawing assets from Layer 2 networks to Ethereum’s base layer can take up to seven days under existing fraud-proof mechanisms. The new system aims to compress that timeline substantially by confirming transactions through mathematical proofs rather than challenge windows.
For institutional participants, the shift addresses longstanding friction around capital deployment. Custody services would no longer need to reserve funds during extended settlement periods, while trading firms could move liquidity between venues more rapidly.
Succinct’s proof systems currently secure billions of dollars in onchain value across multiple protocols.
The partnership fits within Optimism’s broader multi-proof strategy, which envisions letting OP Stack chains choose from different proving networks based on their specific needs.
