Solvere

Your key never moves

You sign in your own wallet, or offline on your own machine with a 430-line signer that has no dependencies and makes no network calls. No website ever asks you for a private key. Any that does is a phishing site — including one that looks like this one.

You see every instruction before signing

The signer decodes the actual transaction bytes and prints every destination and every lamport. An instruction it cannot decode is refused rather than waved through, and a transaction that disagrees with its own description is rejected outright.

One transaction, or nothing

Your money and the fee move together in a single atomic transaction, checked against a simulation of what it will really do. There is no moment where somebody else is holding your SOL.

A fee only if it works

10% of what is recovered, and nothing if nothing is recovered. The rent floor of 0.001462 SOL stays behind permanently on every account — it is not recoverable, and it is not counted as though it were.

We build it and cover the network fee

You receive one file, deal.json. It contains a transaction and no key of any kind. If your authority cannot pay its own fee — which is the usual reason people land here — we pay it.

You check it before signing anything

The signer below decodes the real transaction bytes and prints every destination and every lamport, including our fee. It refuses outright if the file's description disagrees with what the transaction actually does. It signs nothing unless you add --yes.

You sign, on your machine, offline

Your key never moves. The signer makes no network calls and has no dependencies — you can disconnect entirely and it still works.

You send back a signature, not a key

Signing writes deal.signed.json. That file is safe to email: it carries your signature, and altering any amount or address in it invalidates that signature and the network rejects it.
