How to withdraw Kaspa (KAS) from Finst to a wallet

Why withdraw to self-custody at all

Finst holds your KAS for you (custodial). For anything you plan to keep — even a few weeks — a self-custody wallet gives you the keys and removes exchange risk. This guide assumes you have already created a Kaspa wallet (see our best Kaspa wallet guide) and bought KAS on Finst.

There are three reasons to withdraw sooner rather than later:

1. Counterparty risk — a custodial balance is a claim on Finst, not your coins.
2. Kaspa’s unique network — KAS does not work in most generic wallets; confirming your wallet handles it early avoids surprises.
3. The €2.50 baseline — every Finst crypto withdrawal carries a fixed baseline, so one planned withdrawal beats several small ones.

The one thing that causes lost funds

Sending KAS to an address on the wrong network. Kaspa is its own network with its own address format. If Finst’s withdrawal screen ever shows anything other than the Kaspa network, stop.

Kaspa addresses start with kaspa: — the format is the tell. If the destination does not start with kaspa:, it is not a Kaspa address.

Before you start

• A Kaspa wallet with a verified receiving address — Kaspium (mobile), Kasware (browser), Tangem or OneKey^Sponsored (hardware).
• Your recovery phrase backed up — create the wallet, write down the phrase, and test a restore before withdrawing real KAS.
• A verified Finst account — withdrawals require completed verification.
• A plan for the €2.50 baseline — withdraw a test amount, then the rest in one transaction.

Step-by-step walkthrough

Step 1 — Create a Kaspa receiving address in your wallet

Open Kaspium (or your Kaspa wallet) and tap Receive. The app generates a Kaspa address starting with kaspa:. Copy it with the copy button — never type it from memory.

Step 2 — Open the Finst withdrawal screen

In the Finst app or website, open your KAS balance and choose Withdraw. The network must say Kaspa — it is its own network, not Ethereum or BNB Chain.

Step 3 — Paste the address and double-check it

Paste the Kaspa address and compare it character by character. On a hardware wallet, verify the address on the device screen if the wallet offers it.

Step 4 — Check the fee

Finst shows the total before confirming: the €2.50 fixed baseline plus the current Kaspa network fee. This is the moment to decide whether the amount is worth withdrawing now.

Step 5 — Send a small test amount first

Withdraw a few KAS and wait for it to arrive — Kaspa confirms quickly. Only after the test confirms should you send the rest in one transaction (one baseline, not many).

Step 6 — Verify the balance and secure the phrase

Once the full amount lands, confirm the balance in your wallet and keep the recovery phrase offline.

The €2.50 baseline: plan your withdrawals

Unlike Bitvavo, which charges only the network fee, Finst adds a fixed €2.50 baseline to every crypto withdrawal. For small test withdrawals that is fine — but it means frequent small withdrawals are inefficient. Withdraw a test amount first, then move the rest in one transaction.

The math: five small withdrawals cost 5 × €2.50 = €12.50 in baselines alone. One planned withdrawal costs €2.50. If you dollar-cost-average KAS monthly, withdraw monthly — not weekly.

Fees and timing

• Finst withdrawal fee: €2.50 fixed baseline + current Kaspa network fee (typically under €0.10).
• Speed: Kaspa’s BlockDAG confirms quickly; most withdrawals arrive within minutes, plus exchange processing.
• Minimum: the withdrawn amount must cover the baseline and network fee — very small withdrawals are proportionally expensive.

Safety checks before you confirm

• ✅ The destination starts with kaspa:.
• ✅ The network shown is Kaspa.
• ✅ The address matches your wallet character by character.
• ✅ The total fee (baseline + network) is shown and acceptable.
• ✅ Your recovery phrase is written down and tested.

Troubleshooting

The withdrawal is pending. Exchange withdrawals can take minutes during busy periods; if it exceeds a couple of hours, check Finst’s status or support.

The balance hasn’t appeared. Verify the transaction in a Kaspa explorer — if it succeeded and the address was correct, the funds are in your wallet; check you are viewing the right account.

I sent to the wrong network. If the address was not Kaspa, the funds are likely unrecoverable — the test-amount step exists for exactly this reason.

Alternatives to Finst

• Bitvavo also lists KAS and charges only the network fee — cheaper for frequent withdrawers.
• Direct exchange-to-exchange transfers are not recommended — every hop adds fee and risk; withdraw to self-custody once.

The one-withdrawal rule, one more time

Finst’s €2.50 baseline makes withdrawal planning part of the guide, not a footnote. The rule in practice:

• Test first with a tiny amount — pay the baseline once to confirm the address works.
• Then move everything in one transaction — one baseline total, not one per withdrawal.
• Align withdrawals with your DCA cadence — monthly, not weekly; quarterly, not monthly, if the amounts are small.

The math is simple: €2.50 per withdrawal, regardless of size. The best way to pay it once is to treat withdrawals as a deliberate, planned event rather than a habit.

After the withdrawal

Your KAS is now on-chain in your wallet. The wallet’s recovery phrase is the only way to restore it — keep it offline and never share it with anyone, including ‘support’.

Fees and the €2.50 baseline, in practice

Kaspa network fees are small — normally a fraction of a cent — but the Finst withdrawal flow adds a flat €2.50 baseline on top of the network fee for every crypto withdrawal. What that means in practice:

• One withdrawal: the baseline is a rounding error compared with the amount you move.
• Monthly withdrawals: €2.50 × 12 = €30 a year before network fees.
• Coin-by-coin withdrawals: every separate KAS transfer carries its own baseline, so three moves cost €7.50 in baselines alone.

The fix is bundling: accumulate the position and withdraw once or twice a month instead of after every purchase. If you move KAS regularly and the baseline bothers you, compare the withdrawal cost on Bitvavo, which passes on only the Kaspa network fee.

Checking the address, twice

Kaspa addresses start with kaspa: and are longer than most — the format is unique to the network, so it cannot be pasted into an Ethereum or Bitcoin withdrawal field by accident without visibly failing. The real risk is a wrong character inside the address itself. Copy the address from your wallet, paste it at the exchange, and compare the first and last ten characters on screen before confirming. Because Kaspa is not supported natively by Ledger or Trezor, the receiving wallet is usually Kaspium, Kasware, Tangem or OneKey — make sure the wallet you are sending to actually lists Kaspa before the transfer.

If the receiving wallet does not explicitly list Kaspa, stop and verify before sending — a “compatible” claim without a Kaspa entry is the kind of detail that turns a test withdrawal into a lesson.

Step-by-step

1. Create a Kaspa receiving address in your wallet

   Open Kaspium (or your Kaspa wallet) and create a receiving address for KAS. Copy the address — do not type it from memory.

2. Go to the Finst withdrawal screen

   In the Finst app or website, open your KAS balance and choose Withdraw. Select the Kaspa network — it is its own network, not Ethereum or BNB Chain.

3. Paste the address and double-check it

   Paste the KAS address and compare it character-by-character. Confirm the network shown is Kaspa. On a hardware wallet, verify the address on the device screen if possible.

4. Check the withdrawal fee

   Finst charges a fixed baseline of €2.50 per crypto withdrawal plus the current Kaspa network fee. Consider withdrawing a larger amount in one go instead of several small ones.

5. Send a small test amount first

   Withdraw a small amount first and wait for it to arrive. Only then send the rest.

6. Verify the balance and store your recovery phrase safely

   Once the test amount arrives, keep your recovery phrase offline — never in a screenshot or cloud note.

Frequently asked questions

Does Finst charge a fee for KAS withdrawals?

Yes — a fixed baseline of €2.50 per crypto withdrawal plus the current Kaspa network fee. Because of the baseline, withdrawing in one larger transaction is usually cheaper than several small ones.

Can I withdraw KAS from Finst to Tangem?

Yes. Tangem supports Kaspa natively. Open the Tangem app, create a Kaspa address, and follow the same steps.

What happens if I send KAS to the wrong network?

The funds are likely lost. Always confirm the network shown in Finst is Kaspa before confirming the withdrawal.

How is Finst different from a wallet?

Finst is a custodial exchange — it holds your KAS on your behalf. A self-custody wallet such as Kaspium or Tangem gives you the private keys and the recovery phrase.
