Early access

A Telegram approval inbox where your AI agent asks, you read a plain-language simulation, and your wallet signs.

It is not another agent or a policy contract. It is the approval surface for any agent, built around readable simulation and a signature from the user's own wallet, so it works alongside whatever limits an agent already has.

Questions.

Short answers. The docs have the rest.

What is Countersign?

A Telegram approval inbox where your AI agent asks, you read a plain-language simulation, and your wallet signs. It is not another agent or a policy contract. It is the approval surface for any agent, built around readable simulation and a signature from the user's own wallet, so it works alongside whatever limits an agent already has.

What works today?

Countersign is in development. Every feature is on the status list with what ships next, and the app opens in a sample workspace so you can see how it will work.

Do I need a wallet?

No. You can explore without one. Connecting a Solana wallet only shares your public address so Countersign can read your balances; it never asks you to sign a transaction.

Who is it for?

Developers and power users running trading, treasury or ops agents on Solana who want a human check on out-of-policy actions.
