Fees

The protocol fee is charged in basis points and falls as the trade grows. The bands are expressed in US dollars at the time of the trade.

Trade size	Fee	Basis points
Up to $1,000	15 bps	0.15%
$1,000 – $10,000	10 bps	0.1%
$10,000 – $100,000	7 bps	0.07%
Above $100,000	5 bps	0.05%

The boundary is inclusive. A trade of exactly $1,000 is charged at 15 bps, not 10. The bands are a step function, not an interpolation, so there is never a size at which splitting a trade is cheaper than filling it whole at the next tier — the rate only ever falls.

What that costs in practice

Trade	Rate	Protocol fee
$500	15 bps	$0.75
$5,000	10 bps	$5.00
$50,000	7 bps	$35.00
$500,000	5 bps	$250.00

Calculating it

The SDK exports calculateProtocolFee and the tier table itself as FEE_TIERS. The daemon reimplements the same calculation in Rust and is conformance-tested against the TypeScript implementation, so the two cannot silently diverge.

import { calculateProtocolFee } from '@dash-intents/sdk';

calculateProtocolFee(500);      // 0.75   — 15 bps
calculateProtocolFee(5_000);    // 5.00   — 10 bps
calculateProtocolFee(50_000);   // 35.00  —  7 bps
calculateProtocolFee(500_000);  // 250.00 —  5 bps
