tl;dr

  • Agglayer CDK now supports OP Stack (cdk-opgeth), enabling developers to design and launch custom blockchains using Conduit’s lightning fast G2 sequencer
  • Chains using CDK OP Stack connect natively to Agglayer for unified liquidity and seamless cross-chain UX
  • Optional ZK proofs for CDK OP Stack chains, for additional security, now live
  • Agglayer charges nothing to connect and extracts no tax
  • Conduit supports CDK OP Stack, providing the high-performance G2 sequencer

Projects that want to grow need to build chains that can connect seamlessly for unified liquidity and users, without experiencing max value extraction. It shouldn’t matter what stack: L1, L2, OP Stack, zero-knowledge (ZK) chains. Whatever. Like TCP/IP before it, Agglayer unifies all of crypto.

Agglayer CDK gives builders the freedom to custom spec chains, without imposing tax or design requirements. 

Developers can now launch Agglayer CDK OP Stack chains natively connected to Agglayer for fast, low-cost cross-chain interop. And a ZK unified bridge on Ethereum means secure, capital efficient access to liquidity and users. Combining fast finality of ZK proofs (vs. 7 day window for fraud proofs) with the widely adopted development environment of the OP Stack.

Now that Agglayer v0.3 is live, Agglayer CDK OP Stack supports fast ZK finality with optional validity proofs, and transactions that are fractions of a cent.

Ready to begin? Reach out now.

CDK OP Stack chains aren’t subject to Superchain tax or chain governance requirements. No added fee to access shared liquidity and no seven-day withdrawal lockup

That means seamless bridge UX, shared state, and unified liquidity without interop delays. 

That means sovereignty to build a custom chain, your way. 

Connected and secured by Agglayer.

Launch performant, low-cost CDK OP Stack chains 

Agglayer CDK OP Stack (cdk-opgeth) is not a fork or a wrapper, but a native configuration supported directly by Polygon Labs and Conduit. Built on Geth, Ethereum’s most widely adopted execution client, CDK OP Stack is natively optimized to utilize Conduit's G2 sequencer to unleash superior performance. 

Here’s what builders get with CDK OP Stack:

  • No interop tax. Agglayer does not charge rent-seeking fees.
  • No design constraints. ZK tech means chains can safely interop
  • Launch with Geth, Ethereum’s most battle-tested execution client
  • Reach up to 100+ Mgas/s throughput with the G2 sequencer
  • Deploy faster with familiar OP Stack tooling 

CDK OP Stack gives teams familiar infrastructure, performance at scale, and the freedom to connect without constraint.

Build what you want, interoperate across dozens of chains and counting, with a secure bridge to tap into Ethereum’s liquidity and users.

Ready to build?

Agglayer CDK OP Stack already has chains live in testnet, and, with Katana, mainnet. Conduit works directly with teams building with this stack, lending custom-support for custom-designed chains.

Build the chain your users deserve.
