01Add-on: faucet
Create a testnet faucet. Free coins, with sensible limits.
Builders need coins to test your chain, and new users need a first coin to try a wallet. A faucet hands out small amounts on request, with limits so one person cannot take it all.
- $79 one-time
- Limits against draining
- Works on every base

02Why it matters
Nobody tries a chain they cannot touch.
The first question from a developer is always the same: where do I get coins to test with?
Without a faucet
- Every new tester waits for you to answer
- Your best builders give up on day one
With a faucet
- Test coins in seconds, at any hour
- You are not the bottleneck
Builders can test right away
Wallets, apps and scripts need a little balance to run.
Tutorials that actually work
Step one: get coins from the faucet. No waiting.
A first coin in a new wallet
The quickest way to see a wallet come alive.
03How it works
Create a faucet that cannot be drained in an afternoon.
Three checks stand between a request and a payout. Each one stops a different trick.
1. Human check
A CAPTCHA keeps simple bots out.
2. Per-address limit
One claim per address per time window.
3. Per-IP limit
Switching wallets does not get more.
4. The faucet wallet pays
A fixed amount, on chain. You keep the wallet funded.
Rate limits are the whole job. Without them a faucet is empty in an afternoon.
Limits only work when the server enforces them. The browser can be faked.
Keep the faucet wallet small. If it is drained, the loss is capped.

Who is your faucet for?
Test network
For developers
Generous drips of coins with no value. The classic faucet.
Community launch
For first users
Tiny amounts so people can try a wallet. Hard caps.
Main network
For onboarding
Rare, because the coins have value. Keep it small and capped.

Hosted, on your own domain, ready the day you share your first tutorial.
Small and steady
A drip, not a flood.

07Clear lines
What faucet messages mean, and what is not included.
Faucets fail in a few predictable ways. Here is what typical messages mean, in plain words.
Typical messages, explained
“Too many requests, try again later”
The rate limit worked. The person already claimed in this window.
“Human check failed”
The human check did not pass. Refreshing usually fixes it.
“Sent, but not on the explorer yet”
The payout is sent but not yet indexed, or no explorer is attached.
Not included
- Coins to fund the faucet wallet
- Social-account login gates
- Marketing the faucet
- Bot protection beyond limits and a human check
- Advice on giveaways, which can raise tax questions

09Questions
Faucet questions
Real questions people ask before they run a faucet.
How can I create my own faucet for my coin?
Add the faucet in the builder or your dashboard for $79 one-time. It goes live on its own small server under your domain. You fund the faucet wallet.
So, you want to run a faucet: what does it take?
A funded wallet, a small website, a human check and rate limits enforced on the server. The add-on covers all of it except the coins.
How to make a captcha faucet?
The human check is part of the faucet: a CAPTCHA has to pass before any payout. On its own it is not enough, which is why limits per address and per IP sit behind it.
How many times can a wallet request coins from a faucet?
Once per time window, usually a day. Live faucets range from one request an hour to a weekly allowance, per wallet or IP.
What does "Too many requests. Please try again after X minutes" mean?
The person already claimed in this window, so the rate limit is doing its job.
Who pays for the coins a faucet gives away?
You do. The faucet sends from a wallet you fund, so keep it small and top it up when it runs low.
Should a faucet run on the test network or the main network?
Usually the test network, where coins have no value. Main network faucets exist but are rare. If you run one, keep amounts tiny and capped.
Is a faucet for a real-value coin a good idea?
Only with small amounts and hard caps. Giveaways can raise tax questions where you live.
Can people drain the faucet with many wallets?
Limits per IP stop most wallet-hopping, and a small faucet balance caps what anyone could take.
Can I add a faucet after launch?
Yes. Add it from your dashboard whenever testers start asking, and it goes live on your chain automatically.
