Airdrop (Devnet/Testnet)

The process of receiving free, valueless SOL on Devnet or Testnet via the Solana CLI (`solana airdrop`) or public faucet endpoints, used to fund accounts for testing without spending real SOL. Airdrops are rate-limited per IP and per address (typically 1–2 SOL per request, a few requests per hour) to prevent abuse. The term is also used colloquially for token distribution events on Mainnet Beta, but in a network/infrastructure context it specifically refers to the test-cluster faucet mechanism.
