What Is zkLink Nova?
zkLink Nova is a Layer 3 blockchain built atop Ethereum and multiple Ethereum Layer 2 networks. Designed to bridge liquidity across fragmented Layer 2 ecosystems, zkLink Nova consolidates decentralized finance (DeFi) assets while maintaining Ethereum's security. Its native transactional token is ETH.

Understanding Token Approvals on zkLink Nova
Token approvals grant smart contracts permission to spend your tokens on your behalf—a standard practice for decentralized exchanges (DEXs) and dApps. While essential for DeFi functionality, unmonitored approvals pose security risks if left unchecked.
Key Risks:
- Over-permissioned contracts: Unused approvals may expose assets to exploits.
- Phishing vulnerabilities: Malicious actors can manipulate outdated approvals.
Step-by-Step Guide to Revoking zkLink Nova Approvals
- Enter Your Wallet Address
Input your zkLink Nova-compatible wallet address (e.g., MetaMask, Trust Wallet) into the approval checker. Analyze Active Approvals
The tool displays:- Token: Approved asset (e.g., USDC, WBTC)
- Spender: Contract with spending rights
- Amount: Limit granted (specific sum or unlimited)
- Date: Approval timestamp
Filter and Revoke
- Sort by high-risk approvals (e.g., unlimited amounts)
- Click "Revoke" and confirm the transaction via your wallet
- Pay nominal gas fees (typically under $1)
👉 Compare gas fees across networks for cost efficiency
Pro Tip:
Regularly audit approvals—especially after interacting with new dApps.
FAQs
Q1: Can I revoke approvals without paying gas fees?
A1: No. Revoking requires an on-chain transaction, but fees are minimal on zkLink Nova.
Q2: What happens if I don’t revoke unused approvals?
A2: Dormant approvals increase exposure to smart contract exploits or phishing attacks.
Q3: How often should I check my approvals?
A3: Monthly audits are recommended, or after every 10 dApp interactions.
Q4: Does revoking affect active dApp usage?
A4: Yes. You’ll need to re-approve tokens for currently used dApps.
Best Practices for zkLink Nova Security
- Limit approval amounts: Avoid "unlimited" grants; specify spending caps.
- Use hardware wallets: Store ETH and tokens offline when not trading.
