Polygon Labs has partnered with Conduit to launch an improved chain development kit (CDK) called the Agglayer CDK. Recent releases introduce interoperable blockchain infrastructure that allows developers to choose from a variety of technology stacks and automatically connect to Polygon’s Agglayer’s liquidity aggregation layer.
Conduit’s latest rollup framework is here: AgglayerCDK by @0xPolygon
We were in the lab building polygons that would build a new implementation of the CDK that combines @optimism op Stack, ZK security, and agglomerator interoperability.

Toolkit updates allow developers to choose from OP stack configurations built using Ethereum’s open source modular framework. The CDK-Opgeth version connects the Agglayer directly and runs it on the Geth Execution client. It supports more than half of Ethereum Network nodes.
Through this architecture, developers have acquired robust and inexpensive execution systems that offer transaction speeds that offer transaction speeds that exceed 4,700 transactions per second, offering gas delivery with up to 100 million seconds of gas.
Safety and rights as a foundation
One important feature of this operation is that developers do not have to pay to join the network with Agglayer. The non-rent-seeking model supports builder independence and provides security thanks to the pessimistic ZK proof. Security measurements allow individual chains to maintain their entire system safe from potential threats to its integrity.
Planned execution proof upgrades eliminate the traditional 7-day transaction leave delay of optimistic rollups. The concise SP1 system, along with Polygon’s Plonky3 Prover, strengthens this implementation to provide immediate finality while maintaining transaction fees for less than half a cent.
Legacy CDKs available to users
The OP stack option will participate in the lineup of existing products, including Polygon’s original CDK Erigon configuration. The CDK Erigon version works under Gateway.fm management to build bespoke deployments that support native gas tokens, while operating across Zkrollup, Validium and Sovereign networks. Experiments in live environments allowed CDK Eligon to achieve Flores uptime while processing 500 million transactions, reaching a TPS output level of up to 1,000.
Construction towards a multi-stack future
The adoption of multi-stack solutions by Polygon creates new possibilities for blockchain systems interaction across the network landscape. Polygon is actively planning to integrate new stack solutions, including Arbitrum Orbit and ABC Stack, with others. Strategic transformation allows builders to build with tools that support their development needs via Layer 1, Layer 2, ZK Tech, optimistic rollups.
Through the Agglayer CDK, developers access performance-focused modular frameworks that prioritize developer sovereignty and flexibility, and gain interoperability that drives Web3 adoption closer to unified decentralization.
