We’re excited and proud to announce that RiftLend is partnering with Polymer.
Polymer expands RiftLend’s vision by enabling support for chains outside the Superchain, expanding them beyond this cluster and making them a truly multichain protocol.
By integrating the Prove API, RiftLend is able to provide its users with a single interface to deposit assets and access yield across multiple rollups.
RiftLend: A New Kind of Cross-chain Application
RiftLend is the only cross-chain lending platform that is truly multi-chain. Instead of having isolated instances deployed across rollups, RiftLend operates as a single application that has multiple lending pools deployed across multiple chains.
To achieve this, they required real-time updates for rates, parameters, liquidations, withdrawals and deposits from ALL chains. Achieving this with traditional messaging protocols is difficult as:
- RiftLend would have to greatly modify the existing contract logic to fit the rigid structure of messaging protocols
- Adding a new rollup means reconfiguring all existing instances, which is time-consuming and prone to errors
- Each contract instance requires the sending of new messages point to point to keep them in sync. If there are 20 rollups, each rollup would have to send 19 messages, i.e., a single synchronization would need 40 transactions!
All of this means that simply setting up RiftLend across a few rollups would take months of development time. Upgrades would also consume a lot of bandwidth – for example, if RiftLend was set up on 19 rollups and wanted to add support for a 20th rollup, RiftLend devs would have to sit and manually connect all 19 rollups to the 20th one.
Before Polymer, RiftLend could access the Superchain ecosystem by integrating Superchain interoperability, but other chains were still out of reach.
With Polymer however, RiftLend can now access:
- Superchain rollups
- OP stack rollups
- Arbitrum Orbit rollups, and
- Ethereum mainnet
Prove API: Any Action, Any Chain
The Polymer Protocol is a Proving Engine. Polymer generates proofs of on-chain activity from rollups using Ethereum as a settlement layer, and shares the proofs between rollups natively.
Applications can simply use Polymer’s Prove API to verify any data or action with a proof – all in real-time, and in the most efficient and trust-minimized way possible. Today, Prove API can generate and share real-time proofs for all OP stack and Arbitrum Orbit stack chains.
By integrating the Prove API, RiftLend is able to keep a watch on all their cross-chain contracts while keeping them in sync. It's like using a server monitoring tool that keeps an eye on all your different servers that are hosting your data, ensuring they’re in sync with each other.
This enables RiftLend to give its users access to attractive APY – regardless of which chain the yield opportunity is on.
Build with Polymer
Polymer doesn’t just let you build cross-chain applications; it enables use cases that other interop providers cannot scalably support. Polymer is building infrastructure for real-time multi-chain applications that scales infinitely.
