Polymer is excited to announce we are partnering with Epoch Protocol - the first ever universal coordination layer for agents and solvers - to realize their mission of abstracting web3 complexity with intent-based interactions.

Once live, any user or developer will be able to easily incorporate Epoch’s solver and agent ecosystem to enhance transaction flows, improve network and dApp onboarding, and reduce developer efforts.

Epoch: The Era of Intent-Centric Abstraction

Solver networks are now widely acknowledged as the antidote to fragmentation. By offloading execution to sophisticated third party solvers, these networks address one of crypto’s biggest challenges—crosschain latency, and have since become the bedrock of chain abstraction infrastructure.

But to Epoch, solvers and agents are the key to abstracting all crypto interactions, not just chains. This philosophy is evident in Epoch’s self-characterization as a “middle layer for intent-centric abstraction”. Simply put, Epoch connects users, app builders, solvers, and agents with a sophisticated but easy-to-integrate intent coordination layer.

For users, Epoch provides an interface for simplifying multi-step + protocol + chain interactions into natural language intents that are settled in the most resource and path optimized way possible. 

For solvers and agents, Epoch provides a layer for coordinated collaboration and deeper order flow coming from external dApps, wallets and other AI agents. On the flipside, this enables app builders to easily integrate solvers and agents to improve user flows for their protocols and optimize execution for end-users. 

What makes Epoch unique is its Sub-Intent Orchestration feature, which breaks down intents into smaller sub-intents, before orchestrating various purpose-built solvers and agents to fulfill user intents more quickly and efficiently. 

Polymer facilitates crosschain communication between end user wallet, escrow contracts, andrelevant solvers.

Intent & Solver Orchestration with the Prove API

The Polymer Protocol is a Proving Engine. It generates proofs of on-chain activity from rollups and shares the proofs between rollups natively. Instead of passing and verifying messages, applications can simply use Polymer’s Prove API to verify any on-chain event with a proof– all in real-time, and in the most efficient and trust-minimized way possible. 

Polymer benefits Epoch’s protocol in three key areas:

Efficient Solver Coordination: Polymer enhances sub-intent orchestration by facilitating backend “accounting” among solvers, enabling smooth settlement for multi-party fulfillments.

For example, a user wants to bridge $60,000 from Optimism to Base. A single solver may not have the funds available, but three separate solvers could each contribute $30,000, $20,000, and $10,000 respectively. While the user's intent was to simply bridge $60,000, this action required a more complex settlement process where each solver receives their portion of the funds. Polymer facilitates this coordination process for Epoch, by enabling solvers with different specialties and systems to coordinate without significant protocol-level changes.

Single Proof Settlement: Epoch solvers can use Polymer’s Prove API to validate batched intents and multi-party intents simultaneously with a single proof. This significantly reduces the latency and costs associated with verification.

Real-Time Solver Claims: Faster claims increases money velocity for Epoch solvers, increasing profitability while starting a liquidity flywheel for all stakeholders.

Build with Polymer

Solvers will commoditize as adoption increases. This makes purpose-built solvers and solver orchestration increasingly important in the near future for powering abstracted user experiences.

We look forward to closely collaborating with Epoch to realize their vision of a user-friendly solver-centric on-chain economy.
