# Frost Testnet Faucet

> Drips testnet FROST (the native token) on the Frost L1 (an EIP-8141 post-quantum testnet,
> chain id 8141). Rate limiting is a proof-of-work:
> grind ML-DSA-44 keypairs until SHA3-256(pk || token) has the required
> number of leading zero bits, then prove possession by signing the claim.

Flow: GET /api/challenge?address=0x… returns a sealed token and difficulty
(base 15 bits, escalating +2 bits per claim
per address or subnet in 24 h). Grind an ML-DSA-44 keypair matching the rule,
sign "frost-faucet-v1" || token || address with it, then POST /api/claim with
{address, token, pk, sig} (hex-encoded pk and sig). Tokens expire after
300 s and are single-use. Drip: 1000000000000000000 wei.

## API

- [Challenge](https://faucet.frostfi.net/api/challenge): GET, query param `address`
- [Claim](https://faucet.frostfi.net/api/claim): POST JSON {address, token, pk, sig}
- [Status](https://faucet.frostfi.net/api/status): GET faucet balance, budget, queue depth

## Optional

- [Web UI](https://faucet.frostfi.net/): grind in the browser via a Web Worker
- [Explorer](https://explorer.frostfi.net): Frostscan block explorer for the chain
