Base fee in either direction; final fee varies
Know the cost before you pay
The base fee is 2% in either direction. The liquidity adjustment lowers fees for payments that replenish the bridge and raises them for payments that deplete it. This fee component ranges from 0.5% to 5%; market-risk premiums can increase the final fee above 5%.
Your quote shows the exchange rate, bridge fee and amount to pay before you proceed. Your wallet may also charge a Lightning routing fee.
The 100,000-sat payment limit and shared 200,000-sat daily limit use Spamcoin (BTC) sats, not XBT sats. For XBT → Spamcoin (BTC), the payout counts toward the limits. For Spamcoin (BTC) → XBT, the incoming payment including bridge fees counts. Available liquidity may limit payments further.
