Polymer Labs


Polymer’s1 modular IBC2 design allows for chains, like Ethereum3, to easily integrate IBC transport and become interoperable across all ecosystems in a decentralized manner.

Our protocol combines a novel consensus engine4, zero knowledge technology5, and modular IBC6 to create the most efficient and scalable IBC routing solution. Polymer is the first chain dedicated to the routing of IBC packets.

  1. An Introduction to Polymer Labs, Cosmos, and IBC (Inter-Blockchain Communication): Polymer Chain provides a seamless way to provide cross chain communication by utilizing IBC to connect chains even when they may not support IBC natively. 

  2. INTER‑BLOCKCHAIN COMMUNICATION PROTOCOL: IBC is an interoperability protocol for communicating arbitrary data between arbitrary state machines. 

  3. The Multi-hop IBC upgrade will take IBC to Ethereum and beyond: A discussion on some key areas of improvement that Polymer is tackling to upgrade IBC functionality and expand the IBC network across the industry. 

  4. zkMint: The First ZK-friendly Tendermint Consensus Engine: Polymer’s solution that optimizes IBC across all major chains. 

  5. Developing the Most Truly Decentralized Interoperability Solution : Polymer ZK-IBC: ZK-IBC allows different blockchain protocols to communicate with each other without trusting third parties. It does this by verifying the blockchain consensus on-chain. 

  6. Modular IBC for the Modular World: IBC network topology is changing from a homogenous and densely connected network to a heterogenous and sparsely connected network. Modular IBC adapts the IBC protocol to this dynamic environment.
