Eco Routes enable high-performance cross-chain bridging and swap execution, optimized for stablecoins. Today, we’re releasing Routes V2, with changes that upgrade Routes from an EVM-specific protocol to a universal cross-chain execution layer.

Enhancing Routes V1 for Maximum Chain Compatibility

Routes V1 made architectural choices optimized for EVM chains, including EVM-only addressing, self-destruct operations for gas efficiency, fixed token decimal handling, and ABI-encoding non-dependability. Routes V2 is designed to work beyond just EVM-compatible blockchains by introducing universal encoding for non-EVM chains, eliminating self-destruct dependencies to support zkEVM chains, and implementing modular proving.

Streamlined architecture in Routes V2

Routes V2 streamlines Routes into three core contracts: Portal, Vault, and Prover.

Portal: One gateway contract, simpler integration

Routes V2 consolidates IntentSource and Inbox functionality into a single Portal contract deployed on every chain. This unified contract:

Publishes intents and manages intent lifecycle on source chains
Fulfills intents and prevents double-fills on destination chains
Coordinates with Vault contracts for fund management
Interfaces with modular provers for settlement verification

The consolidation eliminates the need for separate entry-point contracts on the source and destination, reduces deployment overhead, and simplifies the mental model for developers. A single contract address on each chain now handles all Routes operations.

Vault: Enabling universal chain compatibility for Routes

Routes V1's Vault pattern used Create2 with self-destruct for gas efficiency—elegant but incompatible with zkEVM and other alt-VM chains. V2 replaces this with thin proxy Vault contracts:

Vaults are deployed via a thin proxy to have near the same gas efficiency as self-destructs
The intent hash is used as salt to derive and deploy the vault deterministically, and now the vault logic is completely decoupled from the deployments
Design supports all EVM variants (CREATE2) and alt VMs like SVM (PDA), including zkEVMs that prohibit self-destruct

These improvements enable universal chain support with Routes v2.

Prover: Choose your security model for Routes

Routes V2 extends beyond V1's fixed Hyperlane prover to support other arbitrary proving mechanisms, including:

LayerZero prover another AMB allowing for push-based settlement
Polymer prover pull-based settlement using efficient proofs
Local prover for same-chain intent execution

Each prover operates independently through a standard interface, giving Eco developers control to configure speed, cost and security requirements to fit their use case, while enabling Routes to integrate future verification methods without protocol changes.

Key capabilities in Routes V2

Support any blockchain with universal addressing

Routes V1's token addressing used bytes20 (Ethereum addresses), fundamentally limiting the protocol to EVM chains.

V2 implements universal encoding with bytes32 identifiers that accommodate any blockchain's addressing scheme. Ethereum addresses pad to bytes32, Solana addresses encode directly, and future chains can represent their native formats without protocol changes. Beyond addressing, V2 handles variations in token specifications. When USDC has 6 decimals on Ethereum but 18 on BSC, or when non-EVM chains use entirely different token standards, the universal encoding automatically manages these conversions. This shift from EVM-specific bytes20 to universal bytes32 transforms Routes from a closed EVM system to an open, chain-agnostic protocol.

Enhanced deadline mechanisms to guarantee execution time

V1 used a single deadline for both execution and rewards, creating tension between user urgency and solver economics. V2 separates these concerns:

Execution deadline: Guarantees when intents must be fulfilled on the destination chain
Reward deadline: Provides solvers flexibility for capital-efficient claim timing

This dual-deadline approach ensures users receive timely execution while solvers can batch operations for gas optimization.

Simplified ERC-7683 integration with additional gas savings

V1 supported ERC-7683 through separate Eco7683OriginSettler and Eco7683DestinationSettler wrapper contracts. V2 moves these functions directly into the Portal contract, eliminating an abstraction layer, reducing gas costs by approximately 15% and simplifying integration for applications already using the standard.

Execute complex actions in a single transaction

V1 handled basic contract interactions but required multiple transactions or auxiliary contracts for complex operations. V2's Portal contract coordinates with an internal Executor contract to enable sophisticated multi-hop routes:

Automatic ETH/WETH conversion
Sequential swap-bridge-swap operations
Arbitrary contract interactions in a single atomic transaction

This eliminates wrapper contracts and reduces complexity for advanced DeFi strategies.

Enable gasless transactions with same-chain intents

V1 required cross-chain operations for all intents. V2's local prover enables same-chain execution through the Portal contract:

Users specify actions to be executed on the same chain
Solvers execute and pay gas on users' behalf
Combined with Permit3, enables completely gasless experiences

Users can now perform swaps, stakes, or any contract interaction without holding native gas tokens.

What This Means for Developers Building with Stablecoins

Eco Routes V2 unlocks powerful new possibilities for intent-based cross-chain execution. With chain-agnostic encoding that enables seamless multi-VM support, streamlined integration through a single gateway contract per chain, and innovative gasless same-chain operations, V2 empowers builders to create experiences that were previously impossible through a single integration.

Whether you're building payment cards with instant cross-chain settlement, wallet platforms offering seamless swaps, or DeFi applications executing sophisticated multi-chain strategies, Eco provides the infrastructure to innovate faster and scale without limits.
