$BNB Confirmed it’s a slippage failure. Increase it only a little—don’t max it out all at once.

[Conclusion]
Once you’ve confirmed it’s a slippage issue, increase it by 0.1 to 0.3 percentage points, then check the minimum received amount again.

[Steps]
1. Don’t jump straight to 5%.
2. After increasing it, check the minimum amount you’ll receive.
3. If it still fails, reduce the amount.

How much have you increased it by at once?

$SOL On Jupiter, the output token is the first thing to check, and the priority fee is the last.

【Bottom line】
Priority fees and slippage both matter, but if the output token is wrong, getting the fee right won’t help.

【Check in this order】
1. Check the mint first
2. Then check the price impact
3. Finally, check the priority fee

What order do you check when looking at a quote?

2. Check the allowance for Approve
3. Check the recipient and amount for Transaction

$USDT authorization succeeded, but you still need to check whether you authorized the contract you intended.

【Conclusion】
A successful transaction only means the authorization was recorded on-chain. It doesn’t mean the recipient was correct.

【What to do】
1. Check the spender after it succeeds
2. Revoke it if it’s wrong
3. Don’t make another exchange before revoking it

Will you check the recipient again after it succeeds?

2. Lower the amount or reject it
3. If you’ve already approved it, plan to revoke it

$SOL Price impact is too high, so the first adjustment is to halve the amount.

[Conclusion]
When price impact is high, reducing the amount is cleaner than increasing slippage.

[Try this]
1. Halve the amount first
2. Get a new quote
3. Consider trading once the impact comes down

Are you more used to reducing the amount or increasing slippage?

The other party wants an on-chain hash for $USDT, but Binance Convert records can’t provide one.

【Conclusion】
A Convert record isn’t enough to prove to someone that funds arrived on-chain.

【What to do】
1. Only on-chain transfers have a hash.
2. Convert happens only between Binance accounts.
3. First clarify which type the other party wants.

Have you ever used a Convert record as proof of a transfer?

2. For rent, top up SOL
3. Handle only one issue at a time

Have you ever mixed up these two messages?

2. Then look through Internal Transactions
3. Count it as received only when the amount matches

Have you checked Internal Transactions?

2. Paste it into your wallet
3. Use the symbol only as a secondary check

Do you add tokens by searching or by contract address?

2. Copy the receiving address from the deposit page
3. Even if both start with 0x, make sure you can tell them apart

Can you tell a contract address from a deposit address?

Would you feel reassured seeing price impact close to 0?
