Session Keys

Session keys require that you whitelist specific contracts and calls with Argent on mainnet. Please reach out to [email protected] On Sepolia testnet, there is no whitelist

To use session keys, make sure your Argent account has co-signers enabled (cfr. the bottom of this page)

What are session keys ?

Solving UX issues in the crypto space have always been the main focus of Argent. With session keys, a user can perform several actions in a dapp without having to manually sign each transactions. In fact, the user authorizes the app the act on his behalf for a limited period of time and within certain constraints (only a few function calls for instance).

Use cases

A great use case is gaming. Session keys enhance the user experience of games by allowing uninterrupted gameplay. Users can authorize dapps to sign required transactions on their behalf, creating a more immersive gaming experience. To experience session keys firsthand, play Influence.

We could also imagine new payment possibilities. Dapps could implement new payment models such as recurring payments, dollar-cost-averaging, subscriptions and more.

The DeFi space could also benefit from Session keys. Apps such as DEXs can achieve the ease and smoothness of CEXs without their many drawbacks. Potential uses include:

• Automatic claim of DeFi rewards

• Automatic rebalancing of liquidity pools

• User safety protections in lending applications, such as the automatic closing of positions approaching liquidation

💡 You can see sessions in action by playing Influence with web wallet. Session keys are also powering the Argent card and the Argent Telegram wallet.

Security considerations

Sessions maintain security through multiple features:

1. User-defined permissions specify exactly what actions are allowed

2. Time-bounded sessions automatically expire

3. On-chain revocation is always possible and so independently from the Argent backend

4. Argent's backend co-signs each transaction

5. Sessions become inactive if backend verification is unavailable

Under the hood

Initializing a session.

Use a session

The Dapp generates a public/private key pair on its side. With this key pair, the dapp can cosign transactions with Argent Backend on behalf of the user. Of course, the dapp can only send transactions that the user specifically allowed. No surprises are possible!
