Testnet wallet.

3Get free testnet DNDR

A new wallet holds nothing. The public faucet gives free testnet DNDR for a short computation your computer runs (a proof-of-work), which makes mass claims costly. It runs in a terminal, not on this page.

1. Copy your address (step 2).
2. Use a terminal on Linux or macOS, or the WSL Linux terminal on Windows (not PowerShell), with curl and Python 3. Open the command below and run its curl line alone: it prints the amount and the difficulty (pow_bits). Then put your address in ADDR and that number in BITS, and run the rest.
3. Refresh the balance and trust it, not the faucet's reply: the faucet uses plain HTTP, so its reply is not authenticated.

# 1. Run this line alone: it prints the amount and pow_bits.
curl -s http://testnet-api.dendranetwork.com:4500/
# 2. Set ADDR and BITS below, then run the rest.
python3 - <<'EOF'
import hashlib, itertools, json, urllib.request
ADDR = "dendra1..."          # your address, copied above
BITS = 20                    # pow_bits, as reported by the line above
for n in itertools.count():
    h = hashlib.sha256(("%s:%d" % (ADDR, n)).encode()).digest()
    if int.from_bytes(h, "big") >> (256 - BITS) == 0:
        break
req = urllib.request.Request("http://testnet-api.dendranetwork.com:4500/",
    json.dumps({"address": ADDR, "pow": str(n)}).encode(),
    {"Content-Type": "application/json"})
print(urllib.request.urlopen(req).read().decode())
EOF

Only a public address and a number travel to the faucet. A refusal says why; the limits are in the Docs.

4Send DNDR

The memo is written on the chain: public and permanent. An address can send only after it has received DNDR.

The chain-id names the network; this page reads it from the chain endpoint, the server it talks to. A transfer is signed for that network only: while it shows “?”, Send is refused.
