Important Notice

Router Chain has been sunset. The previous Router Chain documentation is no longer valid as the old infrastructure has been discontinued.

This documentation focuses on swap and bridge functionality via the new Open Graph Architecture (OGA) framework built by the Router team. All integrations should use the OGA APIs and infrastructure described in these docs.

About Router OGA

Welcome to Router Open Graph Architecture (OGA) - the most efficient onchain swap network; open, permissionless, and built for scale.

What is Router OGA?​

Router OGA (Open Graph Architecture) is a non-custodial, chain-agnostic programmable execution graph designed to unify fragmented liquidity across EVM, non-EVM, and Layer 2 networks.

Router Protocol tackles the fragmentation, high slippage, and brittle settlement that hinder cross-chain trading by introducing a routing layer that achieves sub-10 bps execution costs on block-size trades and 99.5% settlement reliability—while requiring only minimal node-integration overhead and preserving full trustlessness.

Key Highlights​

  • 🚀 Sub-10 bps execution costs on trades up to $50 million
  • ✅ 99.5% settlement reliability across five live chains
  • 🔒 Non-custodial - full trustlessness preserved
  • 🌐 Chain-agnostic - works across EVM, non-EVM, and Layer 2 networks
  • ⚡ <0.5% revert risk with isolated revert logic
  • 🔌 Permissionless - instantly onboard bridges, DEXs, and solver nodes

Core Components​

Router OGA is optimized for institutions, professional market-makers, and DeFi builders through:

  • Permissionless Node Registry & Reputation: Instantly onboards bridges, DEXs, and solver nodes under EIP-712 authentication, with on-chain reputation scoring to favor reliable execution.

  • Split-and-Optimize Engine: Parallelizes large orders into sub-tranches across multiple venues, achieving sub-10 bps slippage on trades up to $50 million.

  • Unified Messaging Hub & Isolated Revert Logic: Adapts between cross-chain protocols (LayerZero, Wormhole) at runtime and confines failures to individual hops, reducing end-to-end revert risk below 0.5%.

  • Modular Hook Architecture: Exposes on-chain hooks for dynamic fee modules, governance-driven routing policies, and custom workflows—enabling seamless integration with developer SDKs and composable order NFTs.

  • Execution & Liquidity Oracles: Provides time-weighted average execution cost and on-chain liquidity metrics to power automated risk management and back-testing.
