Frequently asked
What's the cheapest network to withdraw ETH from Coinbase?
As of our last check (2026-07-03), Base at 0.000005 ETH — a typical value; this exchange passes the live network fee through. If your destination is elsewhere, a withdraw-then-bridge route may still beat the direct withdrawal — run the live comparison above.
Is it safe to withdraw on a cheap network and bridge after?
Generally yes — the major intent-based bridges (Across, Relay, deBridge) and routes vetted by LI.FI settle in seconds to minutes and avoid long-lived wrapped-asset custody, though all bridging carries some smart-contract risk. You do need a small amount of the intermediate chain's gas token; the calculator flags this on each route.
Does Coshpay touch my funds?
No. Comparisons are read-only — live quotes and step-by-step instructions, with no signup and no wallet. If you use the optional one-signature execution on supported cash-out routes, you connect your own wallet and sign the transaction yourself; funds settle through the routing provider's audited contracts and Coshpay still never holds them.
