Answer
Can I launch a coin from an exchange wallet?
No — an exchange wallet cannot sign a launch transaction, so you have to withdraw SOL to a self-custody wallet before you can create a coin.
The exchange holds the keys, not you
When your SOL sits on an exchange you hold a balance in their ledger, not a wallet. The exchange controls the private keys and signs only the transactions its own systems build: withdrawals, trades, transfers between accounts. Creating a coin needs an arbitrary program instruction signed by a keypair you control, and no mainstream exchange offers that as a product.
This is not a policy quirk you can talk your way past. A deposit address is a receiving account the exchange signs for, and the exchange will not sign this transaction, so nothing is created. There is no half-launch to recover from: the mint never exists and no fees are paid.
- Exchange deposit addresses receive; they do not sign.
- Custodial balances cannot be used as a launch authority.
- If a site offers to launch from your exchange login, it is not doing what it says.
What to do instead
Withdraw SOL to a wallet you control, ideally a fresh one used only for this coin. A measured mainnet launch cost 0.01495 SOL total: 0.0144428 SOL of refundable deposits and 0.00051 SOL of network fee, with no platform fee from pump.fun. Withdraw more than the minimum so there is SOL left for the first buy and for network fees.
- Check you are withdrawing native SOL on Solana, not a bridged version on another chain.
- Send a small test withdrawal the first time you use a new address.
- Wait for confirmation before you open the launch site.
- Keep the launching wallet separate from the wallet holding the rest of your SOL.
Third-party creation tools do not change this
Vendors advertise coin creation as a service. Quoted prices read on 30 October 2026 ran from 0.05 SOL plus a 0.002 SOL network charge at Jumpbit, with revokes free and 0.01 SOL per bundled buy, up to 0.5 SOL plus 0.1 SOL per revoke at Smithii and soltokencreator.io. None of them solve the exchange problem, because they still build a transaction for your wallet to sign.
If the signature comes from a wallet the exchange controls, the creator fees are not yours to collect. That is the whole difference between launching a coin and paying somebody to launch one at you.
- Cheap creation is not the same as ownership of the mint.
- Read what the tool asks you to sign; a revoke add-on should mean the authorities end up null.

Can I use a Coinbase or Binance deposit address to launch?
No. A deposit address is an account the exchange signs for, and it will not sign a token launch, so nothing can be created.
What if I only hold SOL on an exchange?
Withdraw it. The launch needs about 0.01495 SOL in total, so a modest withdrawal creates the coin with more left over for trading.
Will a failed attempt cost me anything?
Nothing is submitted, so nothing is charged. On-chain fees only apply once a transaction actually reaches the network, and they are charged even if it then fails.

Mint a Brand draws the icon, banner and stickers, builds the token site on its own subdomain and prepares the launch for your wallet to sign, for $30. Your wallet pays the network fee and is the creator of record.
