gno.land - /r/gnoswap/router

Overview

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

Router domain proxy for single-hop and multi-hop exact-in, exact-out, and dry-route operations.

Live exact-in and exact-out calls validate a deadline and the corresponding amount limit (minimum output or maximum input). DrySwapRoute is a read-only quote path with no deadline or token transfer.

The router fee is charged on output tokens. It defaults to 15 bps (0.15%) and is configurable by admin/governance from 0 through 1000 bps (0–10%); the current rate is fixed for each individual execution.

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

Function

SetSwapFee


              func SetSwapFee(cur realm, fee uint64)

SetSwapFee sets the router fee rate.

Parameters:

cur: current realm context; callers use cross(cur) when crossing into this realm
fee: fee rate in basis points

Halt check: reverts while the Router or ProtocolFee halt scope is active.
