Seamless infrastructure is the missing piece for scaling crosschain building. Real interoperability — not in whitepapers, but in production. Not bespoke integrations, but a developer experience as intuitive as web2. This is how we move from bridges and chains to apps that just work.
Today’s crosschain development is like an IKEA bed: complex, slow, and hard to scale. With over a hundred steps, parts, and tools, IKEA products feel like complex puzzles rather than ready-to-use furniture.
App developers face the same reality when expanding across chains like Ethereum and its L2s, Solana, or Tron, etc. Integrating crosschain infrastructure equals months of slogging away at developer docs and coding. The experience is painfully slow.
Now compare that to Thuma, a minimalist bed that snaps together in a few minutes…no tools needed. Going from unboxing to usable is fast, effortless, and adaptable. This is the crosschain experience Polymer offers developers.
Instead of wrestling with interop, Polymer enables crosschain features like flipping a switch, so devs can focus on building and improving apps. No puzzle. No slog. Just a few simple lines of code to save months of engineering work.
Crosschain Is Pain
Crosschain development has historically been a liability for developers. Most interop protocols have steep learning curves, and require developers to self-integrate and maintain - almost like building and operating a separate application. The setup is often:
-
Time-Intensive: Developers have to learn an entirely new feature set and its smart contracts, build everything, then eliminate any bugs and vulnerabilities. Integrations drag on for months.
-
Labor Intensive: Because of how these protocols were designed, adding a new chain is like rebuilding an IKEA bed from scratch for each chain.
-
Fragmented & Complicated: Each interop protocol has its own quirks, setup, and smart contracts that require additional engineering to work smoothly together.
Crosschain should be a competitive advantage, not a burden. Polymer simplifies this mess into a plug-and-play suite of APIs that make interop as easy as snapping together a Thuma bedframe.
Out of the box, Polymer offers the following advantages:
- Low Code: Configure APIs with minimal code, like customizing a pre-built app.
- **Time to Market: **Apps become crosschain in hours, not months.
- One-Click Chain Expansion: Quickly expand to new chains and grow with your users.
- **Efficient Scaling: **Scale your app across 100s of chains without 100x-ing your cost.
- All-Purpose: Adaptable for any crosschain use case, from multi-chain proofs to data-driven features.
Crosschain, Configured Your Way
Polymer has a set of APIs—Prove, Execute, Connect, and Query—that act like modular blocks. Each handles a piece of a crosschain transaction, letting devs choose what fits their app without rewiring their stack.
A crosschain transaction has three steps:
- Send a signal (e.g., a deposit or vote) on one chain.
- Confirm it on another chain to verify it happened.
- Act on the destination chain, like minting tokens.

Polymer APIs cover the tx cycle from end to end, making it effortless for developers to build and manage crosschain apps.
-
Prove API: Verifies a signal happened on the source chain with a quick, secure proof—like checking a package’s tracking. No complex setups or slog. Just a few lines of code to start proving events across Polymer’s entire network. Learn more here.
-
Execute API: Performs the action on the destination chain, streamlining omnichain wallet, gas, and private key management that’s typically required.
-
Connect API: Adds new chains in hours, not weeks. It’s like plugging in an extension cord to expand your app’s reach. We’re testing this internally, with a public version available soon. Here’s a recent demo where we connected Plume Network in seconds.
-
Query API: Unlocks a new way of development by allowing Users to search for data across chains, like a search option for blockchain data. Need to perform an action based on recent deposits or votes? Query finds them, and Prove verifies.
Instead of coding event by event “I want to prove Event A on Chain B”
An App builder can say “For my address, find and prove all events in the last 7 hours”.
This is how devs build in web2 already. Time for us to evolve.
Build Apps. Not Interop.

Crosschain shouldn’t slow you down—it should power your app’s growth.
Polymer offers a modular approach to building crosschain that emphasizes speed and ease of use, replacing months of engineering with a few API calls. Teams like Lucid Labs, Everclear, Superform, and many others have already integrated our toolkit into their workflows to scale crosschain more efficiently.
