Faucet user guide (testnet)

The faucet is testnet-only and is intended to provide small amounts of KAT for development and testing.

You will need​

  • Your Catalyst pubkey32 address (0x + 64 hex chars) as requested by the faucet UI/API
  • Access to the hosted faucet UI (or your operator’s faucet)

Official public faucet:

  • https://faucet.catalystnet.org/

Steps​

1) Request funds via the UI​

  1. Enter your address.
  2. Complete the captcha (Turnstile).
  3. Submit the request.

On success, the faucet returns a tx hash and an optional “next eligible” timestamp.

2) (Optional) Request funds via API​

Fetch faucet settings:

FAUCET_API_BASE_URL="https://<your-faucet-api-base-url>"

curl -sS "$FAUCET_API_BASE_URL/v1/info" | jq

Expected shape (from faucet backend docs):

{
  "networkName": "Catalyst Testnet",
  "chainId": "0xbf8457c",
  "symbol": "KAT",
  "amount": "0.1",
  "cooldownSeconds": 86400
}

Request funds:

curl -sS -X POST "$FAUCET_API_BASE_URL/v1/request" \
  -H 'content-type: application/json' \
  -d '{ "address": "0x...", "turnstileToken": "token-from-turnstile" }' | jq

Expected shape:

{ "txHash": "0x...", "nextEligibleAt": "2026-02-23T14:06:22.806Z" }

Verify​

  • Open the explorer tx page (template): https://explorer.catalystnet.org/tx/<txHash>
  • Or verify via RPC receipt polling:
    • catalyst_getTransactionReceipt(txHash)

Troubleshooting​

  • Cooldown: faucet enforces per-address and per-IP cooldown (typically 24h).
  • Wrong chain: the production faucet backend enforces a chain id allowlist (testnet only).
