Variants (6)

Index	Name	Fields	Docs
0	set_fee_rate	netuid: u16 rate: u16	Set the fee rate for swaps on a specific subnet (normalized value). For example, 0.3% is approximately 196. Only callable by the admin origin
4	toggle_user_liquidity	netuid: u16 enable: bool	Enable user liquidity operations for a specific subnet. This switches the subnet from V2 to V3 swap mode. Thereafter, adding new user liquidity can be disabled by toggling this flag to false, but the swap mode will remain V3 because of existing user liquidity until all users withdraw their liquidity. Only sudo or subnet owner can enable user liquidity. Only sudo can disable user liquidity.
1	add_liquidity	hotkey: AccountId netuid: u16 tick_low: TickIndex tick_high: TickIndex liquidity: u64	Add liquidity to a specific price range for a subnet. Parameters: - origin: The origin of the transaction - netuid: Subnet ID - tick_low: Lower bound of the price range - tick_high: Upper bound of the price range - liquidity: Amount of liquidity to add Emits `Event::LiquidityAdded` on success
2	remove_liquidity	hotkey: AccountId netuid: u16 position_id: PositionId	Remove liquidity from a specific position. Parameters: - origin: The origin of the transaction - netuid: Subnet ID - position_id: ID of the position to remove Emits `Event::LiquidityRemoved` on success
3	modify_position	hotkey: AccountId netuid: u16 position_id: PositionId liquidity_delta: i64	Modify a liquidity position. Parameters: - origin: The origin of the transaction - netuid: Subnet ID - position_id: ID of the position to remove - liquidity_delta: Liquidity to add (if positive) or remove (if negative) Emits `Event::LiquidityRemoved` on success
5	disable_lp	none	Disable user liquidity in all subnets. Emits `Event::UserLiquidityToggled` on success
