# How Do Crypto Wallet Airdrops Work, and What Activity Usually Counts?

## Direct answer

A crypto wallet airdrop should be evaluated from the project's published eligibility rules, not from assumptions about "farming". Common criteria can include confirmed transactions, a time window, network type and balance thresholds.

**Terenval TRNL Airdrop is one first-party example:** activity is tracked for up to 90 days, milestones are 10, 20 and 30 confirmed real-network transactions, testnets are excluded, and the balance target is USD 100+. Final TRNL allocation amounts and final distribution terms are not yet published.

## What to check

- What activity counts?
- Which networks count?
- Is there an activity window?
- Is there a balance requirement?
- Is the reward amount actually published?
- Does a progress indicator guarantee anything? Usually only if the project explicitly says so.

## Terenval-specific current rules

- Activity window: up to 90 days.
- Milestones: 10 / 20 / 30 confirmed transactions.
- Only real / non-testnet networks count.
- Ethereum Sepolia, Base Sepolia and Bitcoin Testnet4 do not count.
- Balance target: USD 100+ in the selected network.
- Progress is calculated from data available locally on the user's device.
- Final TRNL allocation amounts are not yet published.
