Live on Robinhood Chain Testnet. Mainnet coming soon.
Built for Robinhood Chain

Know what you sign.

Your wallet shows you code. Glossa tells you in plain words what it will do, before you approve it. When it cannot tell, it says so.

Free. No token. No account. Nothing to sign.

26 seconds, no sound needed.
Try it

See what a request really does

An example is already filled in. Pick another one, or paste your own testnet transaction, its hash, or a signature request. Nothing is sent from your wallet.

Data is the long code a wallet shows as "data" or "hex". A hash is 0x followed by 64 characters. A signature request is the text a wallet shows when it asks you to "sign" (it starts with {).
Where do I find this in my wallet?
  1. Before you click confirm, look on the wallet’s confirm screen for a tab or link called Data, Hex, Raw or Advanced details.
  2. Some wallets hide it until you turn on a setting such as “Show hex data” in their advanced settings.
  3. Copy the long code that starts with 0x, or for a signature the text that starts with {, and paste it here.
  4. Already sent it? Copy the transaction hash from your wallet’s activity list instead.

If you cannot find it, do not sign until you know what the request does.

Glossa can be wrong. If a sentence and the facts disagree, or anything looks off, do not sign.

Your wallet

What has a testnet wallet already approved?

Every approval stays open until you take it back. Paste an address and Glossa lists the open ones, the riskiest first, and shows how to close each. Read-only.

Read-only. Glossa never asks you to sign anything. The address is sent to our server and to the chain explorer to find the permissions.
How it works

Three steps. You stay in control.

  1. 01

    Paste it

    Copy what your wallet asks you to approve or sign, or pick one of the examples.

  2. 02

    Read it

    Fixed rules work out who gets what, how much, and for how long. The danger comes first, in plain words. No AI decides anything.

  3. 03

    Decide

    If the sentence worries you, or Glossa says it cannot tell, do not sign. Glossa never signs or sends anything for you.

Our rules:Never guess.Never ask for a signature.Keep the code open.Sell no token.
Mainnet

Coming soon, once we can prove it.

Before Glossa reads requests where real money is at stake, we test it on real transactions labelled by hand and publish how often it gets one wrong. The target: it never calls a dangerous request harmless.

The real Glossa never

  • asks you to sign or approve anything
  • sells a token, runs an airdrop or a presale
  • messages you first, on X, Telegram or Discord
  • asks for a seed phrase or a private key

The only official addresses: useglossa.app.

If Glossa gets it wrong

It can be wrong or incomplete, and a calm sentence is not a promise that a request is safe. If the sentence and the facts disagree, or it says it cannot verify: do not sign.

Beta. Provided as is, without any warranty. You decide what you sign.

Questions

Why testnet first?

Test tokens have no value, so a mistake costs nobody anything. We open mainnet when we have measured how often Glossa is wrong on real transactions, and published the result.

When does mainnet open?

When the accuracy test is done. We will not give a date before then. Follow us on X to hear first.

Is there a token?

No. Glossa has no token and plans none. If you see one that uses our name, it is not ours.

Does AI decide whether something is safe?

No. Fixed rules read the request and raise the warnings. Nothing guesses.

Can it be wrong?

Yes. Treat it as a second pair of eyes, not a guarantee. Every sentence is shown next to the facts it came from. If they disagree, or Glossa says it cannot verify, do not sign.

Why does connecting a wallet not ask me to sign?

Glossa only needs your address to look up what you have already approved. A site that asks you to sign just to connect is a warning sign.

Can Glossa revoke a permission for me?

No, on purpose. It shows you the exact transaction that closes a permission, and you send it from your own wallet. Sites that offer to "revoke everything" for you are a common trick.

Are you part of Robinhood?

No. Glossa is an independent project, built for Robinhood Chain.
