Approval transaction FAQ#

A CRC-20 approval lets a specified spender transfer up to an allowed amount from your account. CenturionDEX may request one before a token swap or liquidity deposit.

Does approval move my tokens?#

Not by itself. It records an allowance. The spender can later transfer covered tokens when another authorized contract action uses that allowance.

Why are there two wallet confirmations?#

The first transaction may approve the token, and the second performs the swap or liquidity action. A smart-account wallet can batch them, but each underlying permission and call still matters.

Does native CTN need approval?#

No. Native CTN is not a CRC-20 token. WCTN is CRC-20 and does use allowances.

What should I verify?#

Check the Centurion network, token contract, spender address, allowance amount, and whether the request matches the action you started. Cancel if the wallet shows a different token or an unknown operator.

Exact or broad allowance?#

An exact or limited allowance reduces continuing exposure but may require another approval later. A very broad allowance is convenient but remains usable until reduced, revoked, or exhausted.

Does disconnecting CenturionDEX revoke approval?#

No. Disconnecting only removes the browser connection. The onchain allowance remains until you change it with another transaction.

How do I revoke an approval?#

Use a trusted Centurion-compatible approval interface reached through verified sources. Select the correct network, confirm the token and spender, and submit the revocation. Revocation itself costs CTN because it is onchain.

Why does the interface ask again?#

The prior allowance may be too small, belong to a different spender, apply to another token contract, or have been reset. Some tokens also require an allowance to be cleared before a new value is set.

Are NFT approvals different?#

Yes. CRC-721 and CRC-1155 operator approvals can authorize transfers of many assets from one contract. Review their scope carefully.

What is the main scam risk?#

A fake site can request an approval that appears harmless and drain tokens later. Never sign from an unsolicited link, and never share a recovery phrase, private key, or password.
