THE SESSION WALLET

Stay in control.
Stay in flow.

Your wallet, with room to play. NYX gives games a temporary key with a spending limit and an expiry—so every move doesn’t need another wallet popup.

No login. No wallet needed. Just explore.

02 / THE IDEA

More freedom.
Defined boundaries.

A wallet approval shouldn’t break the rhythm of a game. NYX explores a simple idea: approve a limited session once, then let a temporary key handle the actions you allowed.

01

One session, fewer prompts.

The session key signs each game move. Your main wallet authorizes the session, so it doesn’t need to interrupt every action.

02

Small permissions. Clear limits.

Choose how much the session can spend and how long it lasts. Its access is restricted to the Signal Tap game.

03

The final say stays with you.

Stop a session whenever you choose. An expired, revoked or fully spent key can no longer make game moves.

03 / HOW IT WORKS

Set it once.
Get into the game.

From your wallet to a temporary key, every step has a clear purpose.

Explore the full flow
  1. 01

    Start with your smart account

    The demo gives you 100 simulated USDC. In testnet mode, connect your wallet and fund your smart account with test assets.

  2. 02

    Create a limited session

    Set a spending cap and duration. Authorize a temporary key that can only perform the game’s permitted action.

  3. 03

    Play without repeated approvals

    Tap the glowing tile. Each move costs 0.10 USDC from your session budget and is signed by your session key.

  4. 04

    Finish on your terms

    Check the activity log, watch your remaining budget or revoke the session. Access ends when its time or budget runs out.

04 / PERMISSION BY DESIGN

A key to the game.
Not to everything.

A session is a narrow permission, with rules the smart account checks before allowing a move.

  • Only the approved game action
  • A total token budget you choose
  • An expiry time and owner revocation

Try a 0.30 USDC example: three moves, then the budget stops play. Or revoke access early.
