How Network Fees Work #

When you send cryptocurrency, you pay for two things:

1. Amount Sent → goes to the recipient
2. Network Fee → goes to Blockchain validators/miners

⚠️ Fees are in addition to the amount you send (not deducted from it).

Sending Native Tokens

• Example: Sending 1 ETH
• Recipient receives: 1.000000 ETH
• Network fee: 0.000420 ETH
• Total deducted: 1.000420 ETH

⚠️ Common Mistake: If you only have exactly 1 ETH and try to send it all, the transaction will fail.

✅ Use the “Max” button to auto-calculate the correct amount.

Sending Tokens (USDT, USDC, etc.)

• Fees are always paid in the native coin of the network, not in the token.
• Example: Sending 100 USDT on Ethereum
• Recipient receives: 100 USDT
• Fee: 0.000420 ETH (paid in ETH, not USDT)
• Required: 100 USDT + 0.000420 ETH

❌ 100 USDT + 0 ETH → transaction fails

✅ Always keep a small ETH/BNB/MATIC balance for fees.

Fee Settings on EVM Networks

• Gas Price → cost per unit of gas (in Gwei)
• Gas Limit → maximum gas units allowed
• Total Fee = Gas Price × Gas Used

⏳ Lower fees = slower confirmations (minutes to hours)

⚡ Higher fees = faster confirmations (seconds to minutes)

Transaction Warnings in Wallet

✅ Green → Sufficient balance for amount + fees

⚠️ Yellow → Borderline, may fail if fees rise

❌ Red → Insufficient balance, transaction will fail

👉 Reminder: Even failed transactions consume Gas Fees!

Cold Wallet Timing Rules

• Fees are calculated and locked at signing time (offline)
• Once signed: Recipient, Amount, Max Fee, Nonce, and Signature are final
• If network conditions change before broadcasting, your transaction may be:
  • ⏳ Stuck (if fees rise above your signed gas price)
  • ✅ Faster but costlier (if you signed above current gas prices)

Best Practice:

• Sign & broadcast promptly
• For delayed use: prepare multiple signed versions with different fee levels (“Fast / Normal / Slow”)

Quick Reference

Q: Why did my transaction fail?

• Not enough for amount + fees
• No native coin for gas
• Network congestion raised fees

Q: How do I send my full balance?

• Use “Max” to auto-deduct fees

Q: Why can’t I send my tokens?

• You need the network’s coin for gas (ETH, BNB, MATIC, etc.)

⚠️Critical Cold Storage Rule:

• Check fees online → Sign offline → Broadcast promptly.
• Outdated gas settings = unconfirmed or failed transactions.
