The most popular wayto build on Ethereum.
50+ chains built on the OP Stack, including Ink by Kraken, Soneium by Sony, and Xlayer by OKX. The same codebase that processes billions of transactions per year is the one your team deploys on day one.

Every chain has different requirements. The OP Stack lets you swap data availability providers, set your own fee logic, define gas token rules, and add integrations - all through configuration, not custom engineering.

Sequencing
Dozens of developers contributing to the OP Stack.
The same modular stack behind Ink by Kraken, Soneium by Sony, Base by Coinbase and 50+ more chains. Battle-tested at billions of transactions, ready to run your chain.

Powered chains
Your team ships from day one. The OP Stack runs standard Solidity and works with the tools developers already use - Hardhat, Foundry, Viem.
EVM compatibility
Deploy existing Solidity contracts without changes. EVM tools your team already uses (Hardhat, Foundry, Viem) work out of the box.
Simple upgrade path
The OP Stack ships continuous protocol upgrades. Your chain picks them up through version bumps - no migrations, no downtime, no re-audits.
Documentation
API references, deployment walkthroughs, and worked examples. Go from zero to a running testnet in under an hour.
