Check it before you move it.

Getting coins off an exchange is a priced decision: which network, which fee, bridge or no bridge. We enumerate the routes and show what actually arrives — ranked by the net units you keep after every measured cost, never by anything else.

What v1 covers — exactly

  • BTC → Bitcoin network: Binance, Bybit, OKX, KuCoin, MEXC, Bitget, Crypto.com, Kraken, Bitpanda — nine venues with an officially published fee.
  • ETH → Ethereum: Binance, Bybit, OKX, KuCoin, Bitget, Crypto.com, Kraken, Bitpanda — eight venues.
  • ETH → Arbitrum One:KuCoin and Bitget — the two venues whose official public fee APIs let us verify the number today. Binance’s and Kraken’s Arbitrum fees could not be verified from an official source at build time, so they have no row yet — absence means “not verified”, never “not offered”.
  • Bridge leg: Ethereum ↔ Arbitrum One, quoted live via LiFi — keyless, neutral, no affiliate.
  • Coinbase & Gemini: publish no fixed withdrawal fee (they pass the live network fee through, disclosed on their own withdrawal screen) — shown as an explanation, never ranked.
  • More assets, chains and venues follow as they can be verified from official sources — the roadmap tracks it honestly.

Method, in short

Withdrawal fees are the venues’ published schedule values, each row backed by an official source with its verification date (most venues adjust them with network conditions). Bridge routes are quoted on the amount that arrives after the withdrawal fee, gas uses the route’s own estimate with a network oracle as fallback — and when no gas estimate exists, the route says “excl. gas” instead of pretending. Routes below a venue’s published minimum withdrawal are not executable and therefore never ranked. Amounts below the published minimums, unquotable bridges, unverifiable fees: all shown as exactly what they are. Full method on the methodology page.

Moving is one decision — trading is the other. The published withdrawal fees live in the withdrawal-fee table, the all-in trading cost in the True-Cost comparison, and whether you get your money out at all is the Reliability Score. Some venue links earn us a disclosed affiliate commission — it never changes the ranking. Data, not advice.
