Polymer: the Ethereum interoperability hub

Polymer is Ethereum's interoperability hub, connecting Ethereum's Layer 2's using the Inter-Blockchain Communication Protocol.

Welcome to the developer hub for Polymer! We're excited to collaborate with you on building the future of interoperability together.

Get started

Here's a quick overview of our documentation, depending on what your goals are:

I want to ...

• Start testing Polymer's features with quickstart tutorials

  Go to Tutorials to quickly experience a cross-chain dApp leveraging Polymer with ready-made demo applications.

• Evaluate why to build cross-chain using Polymer

  Go to Why Polymer to understand the context around the interoperability space, why it's an important issue to tackle and why the current landscape leaves a hole for Polymer to fill.

• Learn the foundations of Polymer, IBC and virtual IBC

  Go to Concepts to dive deep into the concepts making up the Polymer protocol. IBC, virtual IBC as well as the stack to build the Polymer L2 are reviewed.

• Learn how to build dApps that are compatible with Polymer

  Go to Build to find out how to build IBC-enabled Solidity smart contracts and how to find the vIBC core contracts deployed by Polymer that relayers listen to.
