Bitcoin Signet Faucets
A curated list of working signet faucets, an address validator, and the quickest explanation of signet you'll find. Signet is where Bitcoin development actually happens these days — testnet has been unusable for years.

What is signet?
Signet is a private, stable testnet for Bitcoin — like testnet3, but with a signed block scheme that prevents unlimited hash-rate wars, so blocks arrive on a predictable schedule and chain reorganizations are rare. Most modern Bitcoin software development has migrated from testnet to signet because testnet coins became essentially un-faucetable due to abuse and chain instability.
Signet shares all address prefixes with testnet (tb1…,2…,m/n…). To use signet you run bitcoind -signet or set your wallet to signet mode.
Useful commands
Start a signet node
bitcoind -signet
Pruned signet node (~3 GB)
bitcoind -signet -prune=550
Run a private custom signet (you sign blocks)
bitcoind -signet -signetchallenge=<script_hex>
