The safety rules, and why
Closing an empty account and trimming an overfunded one destroy nothing. Burning is permanent. Every rule below exists to keep the second thing from happening by accident.
What is never burned
- Anything with a market. If an aggregator will route a sale, the token is sellable, and the planner refuses to burn it whatever it is worth.
- Anything worth more than a dollar, even if it is flagged as spam.
- Anything we could not price. An unknown value is not the same as worthless, so a failed price lookup means the token is left alone. We would rather leave rent unclaimed than destroy something you wanted.
- Anything frozen by its mint authority, which cannot be burned or closed anyway.
- Anything at all, unless you explicitly tick the burn box. It is off by default.
What happens before you are asked to sign
- Every transaction is built and then simulated against the live chain. A batch the chain will not accept is dropped before you ever see it, with the reason recorded.
- The plan is rebuilt at the moment you press the button, because a Solana transaction is only valid for about a minute. If the numbers changed while you were reading, you are shown the new ones instead of signing the old ones.
- Each batch is confirmed on chain before the next is sent, so the second is judged against a chain that already contains the first.
- If your approval takes so long that the transaction expires, what is left is rebuilt and you are asked once more, rather than the job being abandoned half done.
What DustJar can never do
- Take custody. Rent is returned by the Solana runtime to the account owner. There is no configuration for that and no way for us to redirect it.
- Move a token you keep. We never request an approval, a delegate, or a change of authority.
- Act later. There is no session, no saved permission, and nothing that persists after your transaction lands.
The check that matters most is the one your own wallet performs. It simulates the transaction and shows the balance changes before you approve. A DustJar claim shows SOL arriving. If you see anything else, refuse it.
