Client Wallets

Clients in the Okto ecosystem can manage user onboarding, sponsor gas fees for user transactions, and perform their own on-chain operations. Okto provides two specialized wallet constructs to support these client activities: Treasury Wallet, Paymaster Wallet, and Sponsor Wallet.

1. Treasury Wallet

The Treasury Wallet serves as the client's own on-chain identity. It allows clients to perform on-chain actions independently of user wallets (e.g., invoking their own smart contracts, executing airdrops, or other DApp-specific operations).

• Key Features:
  • Client-Initiated Transactions: Execute transactions directly from a wallet controlled by the client.
  • Aggregated Transaction Execution: Can be used for operations like batch token transfers or aggregated smart contract interactions.

2. Paymaster Wallet

The Paymaster Wallet is a specialized wallet that authorizes and validates gas sponsorship when the sponsorship feature is enabled.

• Key Features:
  • Sponsorship Authorization: Serves as the authorizing entity (feePayerAddress) for transactions where gas fees are covered by the Sponsor Wallet.
  • No Funding Required: The Paymaster Wallet does not require any funds. Its sole purpose is to authorize gas sponsorship.

3. Sponsor Wallet

The sponsor wallet is primarily designed for gas sponsorship. The Sponsor Wallet holds the funds that will be used to pay gas fees for user transactions on supported blockchain networks, enabling a gasless experience for your users.

• Key Features:
  • Gas Fee Sponsorship: Automatically covers transaction fees for user operations when sponsorship is enabled for the specific chain and a valid Treasury Wallet is set as the fee payer.
  • Funding Mechanism: Clients deposit funds directly into the Sponsor Wallet via the Okto Developer Dashboard. These funds are then used exclusively for gas sponsorship.
  • Chain-Specific Sponsorship: Clients can enable sponsorship and fund Sponsor Wallets on a per-chain basis.
  • Policy Integration: (Future scope) Clients will be able to specify policy constraints (e.g., daily volume limit, per-transaction limit) to manage sponsored funds.
