summary: >-
  Alpen ships a public testnet as its sandbox. There is no production/mainnet developer
  surface yet (mainnet v1 contracts are under active audit); all documented endpoints are
  testnet. Value on the network is Signet BTC (sBTC), obtained from a public PoW faucet,
  so no live funds are at risk.
