Smart wallets let owners set per-app session limits (e.g., max 0.1 ETH per transaction, 1 ETH per day). Contracts enforce the cap on-chain. Spending limits can be time-based, per-transaction, or cumulative. They complement approvals by limi
Spending limits are a key smart-wallet security feature — they turn an infinite-approval vulnerability into a bounded risk. They protect against phishing and malicious dapps and are a defining UX of account abstraction.

1. What Is a Spending Limit
A spending limit is a cap on how much a wallet, session, or approval can spend within a period — a security control that bounds losses if keys or sessions are compromised.
2. How It Works
Smart wallets let owners set per-app session limits (e.g., max 0.1 ETH per transaction, 1 ETH per day). Contracts enforce the cap on-chain. Spending limits can be time-based, per-transaction, or cumulative. They complement approvals by limiting exposure even if a dapp is malicious.
3. Why It Matters
Spending limits are a key smart-wallet security feature — they turn an infinite-approval vulnerability into a bounded risk. They protect against phishing and malicious dapps and are a defining UX of account abstraction.
4. Key Facts
- Session keys with limits allow safe dapp automation
- Limits can be reset by the owner at any time
- ERC-4337 wallets support per-session policies
- Limits reduce the blast radius of key compromise
