Testnet is a blockchain environment where developers and users can test things without involving real money. Testnets are the go-to solutions for tinkering before deploying the real deal on mainnet.

Ethereum's Holesky is a public testnet designed for comprehensive staking, infrastructure, and protocol-level testing, specifically for Ethereum's core infrastructure and protocol upgrades. It replaces the Goerli testnet and is focused on enabling developers to thoroughly test changes before implementing them on the main Ethereum network.

Right now, faucet is sending ETH per address, but this may change in the future depending on demand, remaining balance and network congestion.

We use queueing and bundling which means we collect requests & send ETH to those addresses in one shot via smart contract, and this happens every 5 minutes or so. When transaction is broadcasted, it usually takes 15-30 seconds before funds arrive to an address.
