Create a spending limit to enable controlled, recurring payments without requiring full account authority signatures. Spending limits provide a secure way to delegate payment authority for specific tokens and amounts.

​
Spending Limit Concepts

​
Period Types

  • ONE_TIME: Single-use allowance
  • DAILY: Resets every 24 hours
  • WEEKLY: Resets every 7 days
  • MONTHLY: Resets every 30 days

​
Key Components

  • Amount: Maximum spendable amount in smallest token units
  • Mint: Token contract address (e.g., USDC, SOL)
  • Period: How often the limit resets
  • Spending Limit Signers: Authorized addresses that can use the limit
  • Destinations: Optional list of allowed recipient addresses
  • Expiration: Optional expiration timestamp

​
Security Model

Spending limits operate with reduced security requirements compared to full account operations:
  1. Creation: Requires full account authority signatures
  2. Usage: Only requires spending limit signer authorization
  3. Updates: Requires full account authority signatures
  4. Deletion: Requires full account authority signatures

​
Use Cases

  • Employee Expenses: Allow employees to spend within limits
  • Subscription Payments: Automate recurring payments
  • DeFi Operations: Enable automated DeFi strategies
  • Bill Payments: Simplify recurring bill payments

​
Important Notes

  • Amounts are specified in the token’s smallest unit (e.g., 1 USDC = 1,000,000 units)
  • Spending limits reset automatically based on the period
  • Unused amounts don’t carry over to the next period
  • Multiple spending limits can exist for different tokens
  • Spending limit addresses are generated deterministically
