Tier models describe maintenance margin: “With deduction” subtracts a tier-specific amount; “No deduction” does not. This is not a fee comparison. Feature availability depends on region and account eligibility.

Official data sources and comparison methods

dexgc independently collects public contract, funding and margin data, then calculates normalised rates and history statistics. These documentation links make source fields verifiable; they do not imply endorsement by a venue.

Venue	Official reference	How this site uses it
Binance	USDⓈ-M Futures API	Collect mark prices, funding and contract rate periods; 8h is not assumed for every contract.
OKX	Public Data API	Read funding per instrument, retaining contract multiplier, quote and settlement currency to distinguish linear and inverse contracts.
Bybit	V5 Market Tickers	Collect current funding, next funding time and turnover; read risk tiers and maintenance deductions separately.
Gate	APIv4 Futures · Risk limit tiers	One contract listing carries the current rate, settlement interval and fees; sizes count contracts and are converted to the base asset with the contract multiplier. Risk tiers, with their deductions, are read per contract.
Bitget	Futures market API · Position tiers	The ticker listing omits the next settlement time, so it is derived from the contract’s interval; tiers carry no deduction, so maintenance margin is the flat rate of the tier a position falls in.
Hyperliquid	Info API · Margin tiers	Funding settles hourly; the contract’s referenced margin table determines leverage and tier requirements.
Lighter	Funding Rates API · Funding rules	The collector annualises its 8h-equivalent rate separately from the actual hourly settlement interval.
Aster	Aster API documentation	Collect Aster’s own instruments and rates; missing margin tiers remain unavailable rather than borrowing another venue’s tiers.
