Try it on testnet

testnet.nuntio.finance runs the same app and the same contracts on Monad testnet (chain 10143). Money there is test AUSD with no value. The app shows a [ TESTNET ] mark beside the logo.

#The Sandbox

The Sandbox is a shared test team anyone signed in can join. Joining gives you this policy, granted by the Sandbox's owner:

Cartograph Maps and Pinehill Design Studio are left off on purpose, so you can see a refusal and an approval request.

To join, sign in at testnet.nuntio.finance and choose Try the Sandbox. Joining moves no money. It is a policy grant and one approval per service, sent one after another, so it takes a little while, and the screen shows the progress.

Joining is limited:

• 3 tries an hour per person
• at most 300 members
• new members are turned away while the Sandbox holds less than $50

#Two minutes to see the product work

1. Join the Sandbox.
2. Pay Acme Inference API $1. It settles and you get a receipt.
3. Try to pay $3. The contract would refuse it, because it is over your $2 cap, and the app tells you so before anything is sent. It offers to ask for approval instead.
4. Ask Nini to pay Pinehill Design Studio $1. It is registered but not on your approved list, so Nini prepares a request for approval instead of a payment.

#Your own test team

You can also create a team on testnet. Nuntio's grant wallet sends each new testnet team $20 of test AUSD, once, while it has funds. The grant wallet can only send AUSD, at most $20 a transfer.

#Where test AUSD comes from

The public test AUSD faucet is empty: nobody can claim from it any more. Every test dollar Nuntio uses came from earlier claims, so the Sandbox and the $20 team grant are the ways in.
