To remove a website’s saved Cardano wallet connection, use the wallet’s connected-dApp or allowlist settings. In Eternl, go to Settings > App Settings > DApp Allowlist, delete the site, then refresh the dApp. This stops the saved browser connection; it does not undo a transaction you already signed or change your stake or voting delegation.
First, identify what you want to revoke
“Wallet permission” can mean several different things. A website connection, permission to request signatures, ADA collateral, and on-chain delegation are separate controls, so removing one does not automatically change the others.
| What you mean | What it controls | What removal changes |
|---|---|---|
| Saved dApp connection | A website’s access to the wallet’s browser API, where the wallet supports managing saved connections. | Removes that saved access in the wallet. It does not reverse past transactions or change on-chain delegation. |
| Transaction or data signature | A wallet-mediated approval for a specific request. | Rejecting a pending request prevents that approval. Disconnecting later does not reverse a signature or transaction already submitted. |
| Collateral | A wallet setting used for some smart-contract interactions. | Withdrawing it changes collateral availability, not the site connection. A dApp may require collateral to be set again for later use. |
| Stake or DRep delegation | An on-chain delegation choice. | Changing it requires a separate delegation action; removing a site from a wallet connection list does not alter it. |
Remove a saved connection in Eternl
- Open Eternl and go to Settings > App Settings > DApp Allowlist.
- Find the website you want to disconnect and delete its entry.
- Refresh the dApp’s browser tab. If you want to use it again, reconnect; the wallet can then show a fresh permission prompt.
Eternl documents this route in its DApp Allowlist instructions. Menu labels can vary by wallet version, so if the path differs, consult Eternl’s current help information.
For other wallets, use that wallet’s connection controls
Cardano’s CIP-30 standard describes a browser-wallet interface, but it does not define one universal menu for revoking saved website connections. Look in your wallet for connected dApps, approved sites, a DApp connector, or an allowlist, and follow that wallet’s current official instructions. Do not assume the same steps apply across wallets.

CIP-30 requires a wallet to request permission before exposing its API to a website. A connected dApp may read wallet addresses and unspent transaction outputs (UTxOs), and may ask the wallet to sign transactions or data. The wallet mediates those requests; the connection is not the same as giving a website your seed phrase or private keys. See the CIP-30 standard and Cardano developer documentation on wallet connections.
Handle signature requests and completed transactions separately
If a wallet prompt is open and you do not understand or want the requested action, reject it. Removing a saved connection is not a substitute for deciding whether to approve a pending signature.

If you already approved and submitted a transaction, disconnecting the dApp does not cancel it. Check the transaction’s status and contact the wallet or dApp for help specific to that transaction. Do not assume a browser disconnect can undo an on-chain action.
Nor should you assume that a Cardano wallet connection is an ERC-20-style token allowance. The wallet-connection and signing documentation describes the browser API and wallet-mediated approvals; it does not establish a universal model for every Cardano contract or dApp. For a specific contract interaction, check the relevant dApp and transaction details.

Collateral is a separate wallet setting
If your concern is ADA set aside as collateral, use the wallet’s collateral controls rather than its connected-site list. Lace says collateral can be withdrawn at any time, though a dApp may require it to be set again for a later interaction. Lace’s FAQ specifies 5 ADA when collateral is required in Lace; that figure is Lace-specific, not a universal Cardano network requirement. See Lace’s FAQ.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Stake and DRep delegation require separate on-chain changes
Removing a dApp from an allowlist does not change stake delegation or DRep delegation. Cardano describes stake delegation as an on-chain delegation certificate; DRep delegation is a separate governance action that lends voting power without ADA leaving the wallet. To change either, use the wallet’s delegation controls and follow its current instructions. See Cardano’s documentation on stake delegation and DRep voting delegation.
