Terms of use

These terms apply to builder.registrai.cc and its API (the "site"). By using the site you accept them. If you don't, please don't use it. Our Privacy notice explains what personal data we process, and the Pilot rules are part of these terms for the points pilot.

1. What the site is

• Builder registry and project data. Profiles of projects on Arc, built from public on-chain data and public sources, each fact with its evidence. See How we publish.
• Arc indices. ABI (Arc Builders Index), AII (Arc Integrations Index) and AEI (Arc Ecosystem Index): hourly figures computed from public Arc data by the published method.
• Points pilot. A game in which signed-in wallets take long or short positions on ABI, AII and AEI with play points. It is closed until we announce it open.

The site asks you to send a transaction only to lock, withdraw or claim REGI in your own vault contract for the points pilot (locking first approves that contract to move the REGI you lock). Orders are never transactions, and the site never asks you to deposit funds. Signing in is a free message signature.

2. Who may use it

You must be at least 18 years old and able to agree to these terms. Signing in to the points pilot confirms both. Don't use the site where doing so would be against the law that applies to you.

3. Data, indices and attributions

• Data is provided as is, for information. It can be incomplete, delayed or wrong, and we may correct, recompute or restate it, including past index values, when the method or the inputs change.
• Company and wallet attributions come from public sources. Where one rests on a third-party label (for example an explorer name tag), the site says so. Projects can ask us to correct a fact at [email protected].
• Nothing on the site is investment, legal or tax advice, an offer, or a recommendation to buy, sell or hold any asset.
• The indices are not provided for use as a benchmark in financial instruments, financial contracts or investment funds. Don't use them that way.
• Project names, logos and trademarks belong to their owners. Independent. Not affiliated with Circle or Arc.
• The Data API at builder.registrai.cc/api/v1 is free to use under the Creative Commons Attribution 4.0 licence (CC BY 4.0): credit "Data: Registrai" with a link to builder.registrai.cc. The points above still apply to data from the API. Rate limits apply, and we may block abusive use.
• Paid extras on the Data API are sold per request through x402 in USDC on Arc. The payment buys delivery of that response; the data is under the same CC BY 4.0 licence. Payments are final once the response is delivered. A request whose payment fails is not charged; if a payment's outcome can't be confirmed at once, retrying the same request with the same payment returns the data once it is confirmed, or contact us at [email protected].

4. The points pilot

• Points only. Points have no value. They can't be bought, sold, transferred, exchanged or withdrawn, and they give no right to any payment, token, prize or other benefit. There are no prizes.
• Locked REGI. REGI you lock stays in your own vault contract on Arc, which only your wallet can move it out of. You can withdraw it at any time, and the pilot never takes or spends it. The pilot only reads how much is locked. Locked REGI keeps its REGI holder distributions, which you claim from the vault yourself.
• Markets. The pilot trades ABI, AII and AEI. One points balance per wallet covers all three. You hold one direction at a time in each market. The economy (house, fee pool, insurance and weekly split) is kept per market.
• Accounting shown in points. The economy figures (house, fee pool, insurance, weekly split, including the treasury share and its buyback line) are bookkeeping in points inside the game. They are not payments and not a commitment to buy REGI or anything else.
• Eligibility. You must hold at least $10 of REGI in the wallet when you sign in and when you place each order; closing a position needs none, and a wallet with open positions can sign in without it, to close them. Leverage above 1× needs at least $50 of REGI locked in your own vault. Dollar amounts use the median price of the REGI/USDC pool over the last 24 hours. Each leveraged position keeps the lock amount needed when it opened; a withdrawal that leaves less than that closes the position at the next price, with the normal close fee, funding and borrow. The leaderboard lists only wallets that currently hold the amount needed to join. Holding or locking REGI is only an eligibility check; it gives no rights in the pilot. We don't sell REGI.
• One person, one wallet. Running several wallets to improve leaderboard places is not allowed.
• Fair play. Don't try to move the index to profit in the pilot (for example with self-made or wash payments into tracked contracts), exploit bugs, automate abusive traffic, or interfere with the site. We may reset, adjust or remove points, positions or accounts that result from such conduct or from errors.
• Changes. We may change the rules and parameters, pause trading, start a new season, reset balances, or end the pilot at any time. The current rules are on the Pilot rules page.
• Public leaderboard. The leaderboard shows a shortened wallet address and its points.

5. Your wallet and signatures

You are responsible for your wallet and the messages and transactions you sign. We never ask for a private key or seed phrase. Check that a sign-in message names this site before you sign it, and check what your wallet shows before you confirm a lock, withdrawal or claim. Transactions on Arc are public and can't be reversed.

6. Acceptable use of the site and API

Use the site and the public API in a way that doesn't harm it or other users: no attempts to break security, no traffic meant to overload it, and no circumventing rate limits. We may block requests that do.

7. Availability and third parties

We provide the site without any guarantee that it is available, uninterrupted or error-free. It relies on third parties we don't control, including the Arc network and its RPC providers, your wallet software and our hosting providers.

8. Liability

To the extent the law allows, Registrai is not liable for losses arising from the use of the site, its data or the points pilot, including decisions you make based on them. Nothing in these terms limits liability that can't be limited by law, or rights you have as a consumer that can't be waived.

9. Changes to these terms

We may update these terms. The date at the top shows the current version; continuing to use the site after a change means you accept it.

10. Law and contact

Polish law governs these terms, without depriving consumers of the protection of the mandatory law of their country of residence. Questions, corrections and complaints: [email protected].
