Unichain’s public mainnet is expected to launch early 2025 Uniswap says

Unichain, a DeFi Layer 2 solution built on the OP Stack by Uniswap, is set to launch its public mainnet in early 2025. It has been operating on Ethereum’s Sepolia testnet since October, processing over 50 million transactions and deploying 4 million contracts, with 99% uptime.

From Jan. 6, 2025, Sepolia will undergo maintenance to activate permissionless fault proofs, which enable participants to verify and challenge invalid transactions, enhancing security. Following this, the mainnet will open to the public, allowing users to bridge funds and use Unichain apps.

Future updates include Flashblocks, reducing block times to 250 milliseconds for nearly instant transactions.
