Constants¶

DefaultMaxAddLiquidityLimitPerBlock¶

The maximum percentage of a pool's liquidity that can be added in a block. Represented as an optional non-zero fraction (nominator, denominator) with the max value being 10_000. If set to None, the limits are not enforced.

Value¶

(500, 10000)

Python¶

constant = substrate.get_constant('CircuitBreaker', 'DefaultMaxAddLiquidityLimitPerBlock')

DefaultMaxNetTradeVolumeLimitPerBlock¶

The maximum percentage of a pool's liquidity that can be traded in a block. Represented as a non-zero fraction (nominator, denominator) with the max value being 10_000.

Value¶

(5000, 10000)

Python¶

constant = substrate.get_constant('CircuitBreaker', 'DefaultMaxNetTradeVolumeLimitPerBlock')

DefaultMaxRemoveLiquidityLimitPerBlock¶

The maximum percentage of a pool's liquidity that can be removed in a block. Represented as an optional non-zero fraction (nominator, denominator) with the max value being 10_000. If set to None, the limits are not enforced.

Value¶

(500, 10000)

Python¶

constant = substrate.get_constant('CircuitBreaker', 'DefaultMaxRemoveLiquidityLimitPerBlock')

Errors¶
