Pool Ratio

weight: 0.30

Your deposit size relative to total pool TVL. Larger pools provide better privacy.

score = min(100, (pool_tvl / 10,000,000) x 100)

$10M+ pool = 100. $5M pool = 50. Smaller pools = lower privacy.

Anonymity Set

weight: 0.40

Number of similar-sized deposits you blend with. Higher = harder to trace.

score = min(100, (anon_set / 512) x 100)

512 depositors = 100. 256 = 50. 64 = 12.5.

Deposit Delay

weight: +bonus

Waiting blocks before withdrawal breaks timing correlation.

bonus = min(20, delay_blocks x 2)

10 blocks = +20%. 5 blocks = +10%. Instant = +0%.

Relayer Usage

weight: +bonus

Using a relayer hides your gas-paying wallet from the withdrawal.

bonus = use_relayer ? 10 : 0

Relayer = +10% privacy. Direct withdrawal = +0%.

Privacy Levels

LEVEL	SCORE	DESCRIPTION
MAXIMUM	90-100	Full anonymity. Large pool, high anon set, delayed withdrawal, relayer.
HIGH	70-89	Strong privacy. Good pool size, reasonable anon set, some delay.
STANDARD	50-69	Moderate privacy. Acceptable for most use cases.
LOW	30-49	Weak privacy. Small pool or few depositors. Consider waiting.
NONE	0-29	Insufficient privacy. Pool too small or timing too obvious.
