Testnet airdrops explained

Testnet tokens are free. You request them from a faucet, so participation costs time and attention rather than capital. Nothing is at risk beyond the hours spent, which makes this the one route open to people without money to deploy.

The cost is patience. Across every archived case, the gap between a testnet opening and a token arriving ran from one to three years.

Berachain ran two public testnets across roughly two years and weighted people who stayed through both, then distributed around $690M, the largest of 2025.

Sei ran its testnet in phases long enough to separate sustained participants from wallets that appeared once. Walrus required actually storing and retrieving files, which produced a cleaner record than a transaction count would. Initia ran a structured campaign across multiple connected rollups.

• Completing the tasks set. Most campaigns publish a list. Working through it is the baseline.
• Returning across phases. Testnets run in rounds, and weighting has consistently favoured people present in several.
• Using the distinctive feature. Walrus rewarded storing data because storage is what it does. The action that matters is usually the one the chain exists for.
• Reporting problems. Finding bugs is the original purpose, and contributors are often recognised separately.

Most testnets do not lead to an airdrop. The seven in our archive are the ones that did; many more have run without a distribution, and a project can abandon a launch entirely.

Testnets are also the easiest thing to farm at scale, since participation is free, which means they carry the heaviest sybil filtering. See how sybil detection works.
