Polygon Labs, in collaboration with Conduit, has introduced an enhanced version of its Chain Development Kit (CDK), named AggLayer CDK. The newly launched toolkit is designed to support interoperability between diverse blockchain technologies while automatically linking developers’ networks to Polygon’s liquidity aggregation layer, AggLayer. This integration streamlines access to shared liquidity and accelerates the development of decentralized applications (dApps).
With the latest update, developers now have the flexibility to utilize a variety of technology stacks, including those based on the OP Stack architecture. This setup, derived from Ethereum’s open-source modular framework, provides tailored configurations for different project needs. Notably, one version named cdk-opgeth connects directly to AggLayer and operates on the Geth execution client, a foundational component utilized by over half of Ethereum’s nodes.
Boosted Performance and Fee-Free Integration
The AggLayer CDK architecture brings substantial performance improvements. Developers benefit from a system capable of executing more than 4,700 transactions per second, while handling gas throughput of up to 100 million units per second. These enhancements result in a low-cost yet highly efficient execution environment.
One standout feature of this architecture is its non-rent-seeking model. Developers are not required to pay fees to connect their chains to the AggLayer network, a move that underscores Polygon’s emphasis on fostering independent development. In terms of security, the system is underpinned by pessimistic zero-knowledge (ZK) proofs, which ensure the integrity of the entire infrastructure by enabling each connected chain to contribute to system-wide security.
Next-Generation Security and Faster Withdrawals
Planned upgrades to the system’s execution proof mechanism are set to remove the typical seven-day delay associated with transaction withdrawals on optimistic rollups. The implementation is powered by a combination of Succinct’s SP1 system and Polygon’s Plonky3 prover. This setup aims to deliver instant finality and drastically reduce transaction fees to less than half a cent.

We’ve been in the lab with Polygon building a new implementation of CDK that combines the @Optimism OP Stack, ZK security, and Agglayer interoperability.

The newly supported OP Stack configurations join the pre-existing CDK Erigon offering. The Erigon version is managed by Gateway.fm and is engineered to support custom deployments using native gas tokens. It functions across zkRollup, Validium, and sovereign blockchain environments. Real-world tests of CDK Erigon demonstrated the ability to handle 500 million transactions with minimal downtime and achieve throughput rates of up to 1,000 transactions per second.
Expanding the Multistack Ecosystem
Polygon’s adoption of multistack solutions is positioning the network as a hub for versatile blockchain development. The organization is reportedly working toward integrating additional stacks such as Arbitrum Orbit and ABC Stack, expanding the toolkit options for developers. This ongoing transformation is intended to provide builders with the technological freedom to work across Layer 1, Layer 2, ZK-based systems, and optimistic rollup protocols.
Through the deployment of AggLayer CDK, Polygon is aligning its infrastructure with the evolving needs of the Web3 ecosystem. The modular design not only enhances developer autonomy and cross-chain interoperability but also brings the blockchain community a step closer to achieving a cohesive decentralized future.
