Sign a closure request
Someone sent you a link asking you to co-sign an account closure. Here is how to review it and sign safely.
You received a link like https://demolisher.app/sign?id=.... It asks you to add your
signature to a transaction that permanently closes a Stellar account.
Read the page before you sign. It shows you exactly what the transaction does.
What you see
The page opens on Review, then sign.
What you're signing. The account being closed, and a decoded list of every operation in the transaction, one line each. Operations that destroy something are marked in red. You never sign opaque base64 here.
Progress. A Signing weight collected bar, then every signer on the account with its weight and a Signed or Pending badge. This updates live as other people sign.
Check these before signing
Signing helps permanently close the account. Confirm all three of these first.
- The account being closed is the one you expect. It is shown in full near the top.
- The operation list matches what you agreed to. Look at the destination address on the merge operation in particular.
- The network badge is right. It sits beside the What you're signing heading.
Sign
Two ways, both entirely local:
- Connect wallet and sign. Opens your wallet, which shows its own confirmation.
- Paste your secret key. Your key is used only in this browser to sign and is never uploaded or shared.
When your signature is accepted you see Your signature is in, telling you either that the close now has enough signatures or that it still needs more signers.
Things the page refuses to do
The app re-computes the transaction's hash from the link id and compares them before anything renders. That means a link cannot show you one transaction and have you sign another.
| Message | What it means |
|---|---|
| This request can't be opened | The link is missing its id, the transaction does not match the link, or the request could not be loaded. Ask the sender for a fresh link. |
| This request can't be verified | The transaction is not a single account close on this network. Do not sign it. |
| This key isn't a signer on the account | The key you signed with is not authorized on that account, so the signature does not count. Sign with one of the keys listed on the page. |
After you sign
Nothing else is required from you. The person who started the close submits it once enough signatures arrive. Your signature alone does not close the account unless your weight meets the threshold on its own.
Your signature cannot be reused elsewhere. A Stellar signature covers one transaction on one network, so it cannot be replayed against a different close or a different network.
