Fees & FX Methodology

Last updated: 2 October 2025 (Europe/Warsaw)

This page explains how prices, FX, and fees are formed (methodology). Numbers and specific rates may vary by pair, liquidity, and risk.

1) Pricing components

  • Reference rate (mid): blended from reputable market data sources (e.g., multiple aggregators/liquidity venues).
  • Spread / margin: markup applied to cover liquidity, volatility, and operational risk. Spread can differ by asset/pair, size, and risk profile.
  • Network fee: blockchain fee required for the payout transaction; varies by network conditions.
  • Processing fees: card/payment processor fees where applicable.
  • Rounding & quote validity: quotes are rounded to supported decimals and valid for a short window to reduce slippage.

2) Indicative formula (no numbers)

For a pair BASE/QUOTE:

  • mid = blend( sources[BASE/QUOTE] ) (weighted average, with fallbacks)
  • price_quote = mid × (1 + spread%)
  • Final amount you pay/receive = price_quote × size ± network_fee ± processing_fee

Where applicable, cross-currency FX is applied before spread.

3) Execution & updates

  • Quotes refresh frequently and may be frozen for a brief time once you confirm an order.
  • In abnormal markets (low liquidity/high volatility), quotes may be paused or recalculated.

4) Visibility

  • We show the pair, direction, quote, validity window, and an estimate of network fees before you confirm.
  • After execution, you see a receipt with the parameters used.
