Hi this is live now!

Make a multichain faucet are very useful in testnet any project in crypto world

Thanks - this is planned.

Faucets are good for early testing of smart contracts, and having them in one place makes it easier to maintain for people running them, and avoids having to go through multiple websites during cross-chain development... I've seen some multi-chain faucets that don't actually work and allow claiming only for one chain.
