gno.land - /r/gnoswap/router/

Overview

Package router provides swap routing and execution across GnoSwap liquidity pools.

The router handles token swaps with multi-hop routing, slippage protection, and automatic GNOT wrapping/unwrapping. It supports both exact input and exact output swap modes with deadline validation.

Key features: - Multi-hop routing across up to 3 pools - Quote distribution for optimal execution - Native GNOT handling with automatic wrap/unwrap - Slippage protection via min/max amounts - Router fee (0.15%) on all swaps - Deadline enforcement to prevent stale transactions

The router acts as a proxy to version-specific implementations, currently routing to v1 for all swap operations.
