Ethereum Stamp
The Ethereum Stamp recognizes your on-chain activity across Ethereum and compatible networks. It offers tiered credentials based on your transaction history.
Quick Facts
| Detail | Value |
|---|---|
| Cost | Free |
| Time | ~2 minutes |
| Supported Networks | Ethereum, Arbitrum, Base, Optimism, Polygon, zkSync |
| Validity | Until activity thresholds change |
Tiers
The Ethereum Stamp has three credential tiers based on cumulative on-chain activity:
| Tier | Requirements |
|---|---|
| ETH Enthusiast | Entry-level on-chain activity |
| ETH Advocate | Moderate on-chain activity |
| ETH Maxi | Extensive on-chain activity |
Activity Metrics
Your activity is evaluated across the supported networks using these metrics:
- Gas spent — 0.25+ ETH in total gas fees
- Transaction count — 100+ total transactions
- Active days — 50+ distinct days with on-chain activity
Meeting higher thresholds across these metrics qualifies you for higher tiers.
Step-by-Step Verification
- Navigate to the Passport App and connect your wallet.
- Select the Ethereum Stamp.
- The system will scan your on-chain activity across all supported networks.
- Based on your activity, you will be assigned the appropriate tier.
- The stamp will be added to your Passport.
Supported Networks
Activity is aggregated across the following networks:
- Ethereum Mainnet
- Arbitrum
- Base
- Optimism
- Polygon
- zkSync
Troubleshooting
- Lower tier than expected — Activity is measured across specific metrics (gas, transactions, active days). Check that your wallet has sufficient activity across all criteria.
- Activity not detected — Ensure you are connecting the wallet with the most on-chain history. Activity from multiple wallets cannot be combined.
- Network not counted — Only the six listed networks are supported for this stamp.
