Frequently asked questions and what to do when you're stuck

An access right (MCP access) for your AI to connect to the knowledge in the book “Physical AI — AI Begins to Move the World.” The book's text, a PDF and a physical card are not included.

A one-time purchase of 1,000 JPYC or 10 USDC (either: tax included, fixed amount). The yen value of 10 USDC is not guaranteed to equal 1,000 yen. Service is guaranteed for at least 3 months from the date of purchase. It does not stop working automatically after 3 months — you can keep using it as long as the service continues — but provision is not guaranteed forever. Fees on the AI service side and the network fee for the transfer are separate.

Payment is in JPYC or USDC. Please use only the currencies and networks shown on the purchase screen. For USDC, the amount is 10 USDC (fixed).

No. You can use MetaMask and other wallets shown on the purchase screen. Even if a wallet can be used to log in, only the currency and network combinations shown on the purchase screen can be used for payment. You do not need to prepare HashPort Wallet for Biz (a wallet for sellers).

It can take a few seconds to appear. If it doesn't appear or has expired, close it and show it again. Do not send the QR code or the “Copy link” connection link to anyone else.

Go from the WalletConnect icon. It is different from the QR for sending funds. The display may change with wallet app updates, so check the connection URL.

This notice appears when connecting to an external service. When logging in, continue with “このまま接続する” (connect as is) without changing settings. If you are asked for a transfer or an Approve while logging in, do not approve it.

Your AI must be able to add a custom MCP connection (connector). Supported plans and features vary by company, so check in advance whether your own account can add one. Requirements for each AI are summarized in the AI connection guide.

In Cursor, you can register the MCP connection for all projects (~/.cursor/mcp.json) or for a specific project only (.cursor/mcp.json inside the project). If you register it for one project only, it may not appear in other folders. Your purchased access right and connection codes are not tied to a folder. We usually recommend registering it in the shared settings. If you have already connected with project-only settings, you may need to authenticate again in the shared settings. Do not re-enter a used connection code — issue a new one on your page.

Any AI that can set up a connection to a remote MCP server (with OAuth authentication) can connect with the same connection URL and connection code. Steps for Antigravity and Gemini CLI are also in the AI connection guide.

For refunds and what happens with mistaken transfers, please see the terms of use and the legal notice under the Specified Commercial Transactions Act shown on the purchase screen (in Japanese).

WhenBefore starting a purchase

Prepare a supported wallet and keep your recovery information, such as the recovery phrase, safely yourself. Prepare JPYC or USDC and the network fee (gas) needed for the transfer, and pay with a combination shown on the purchase screen.

WhenBefore choosing a wallet

No. Even if a wallet can sign the login message, it may not be usable for payment. Use a wallet, chain and currency shown as available on the purchase screen.

WhenBefore logging in

You may need to switch back and forth between the wallet app and the browser. Check the supported environments on the purchase screen to see whether you can buy with a phone alone. We recommend scanning a QR code shown on a PC with your phone's wallet.

WhenWhile logging in

Open the QR-scanning feature in your phone's wallet app, such as “connect to an external service,” and scan the QR code on your PC. If it can't be scanned, show the QR code again and try once more. Do not share the connection link or QR code with anyone.

WhenWhile logging in

Connecting and signing are separate actions. Check the connection, the wallet and the account you are using, and log in again. If the signature screen asks for a token transfer or an Approve, do not approve it and cancel.

WhenBefore ordering

No. Once the identity-check signature is complete, an order confirmation screen appears. Check the amount, network, currency, gas and so on, then approve the transfer as a separate action. Signing alone costs nothing.

WhenBefore approving payment

Check your balance of the currency needed for payment and the fee (gas) for the network you chose. If it's not enough, don't approve the transfer in your wallet; top up your balance and check again on the purchase screen.

WhenDuring payment

If you cancelled, the purchase has not been completed (it's normal that it doesn't show as paid). Check the order status on your page, then go through the steps again.

WhenConfirming payment

Do not send again. Log in to your page with the wallet you bought with and check the order status. If it isn't resolved, contact us with your order number and transaction ID (no private key needed).

WhenConfirming payment

Open “Already purchased” on the product page and log in with the wallet you bought with. You can check the status of the order and payment.

WhenAfter purchase

The Access Pass is tied to the wallet you used to buy it. Logging in with a different wallet won't show your purchased Access Pass. Switch to the wallet you bought with and log in again. The access right cannot be moved to another wallet.

WhenAfter purchase

Continue from “AIにつなぐ（マイページへ）” (connect your AI — to your page) on the purchase-complete screen. Later, return to the same page from “Already purchased” on the product page or in the guide, and log in with the wallet you bought with. When using a phone wallet with a PC, show the QR code with “スマホWalletでログイン（WalletConnect QR）” (Log in with phone wallet) on the PC, approve the connection and signature on your phone, and your purchase appears on your page on the PC.

WhenAfter purchase

It may not appear if you haven't bought yet or payment is still being confirmed. Also check that you are logged in with the wallet you bought with. If it still doesn't appear, don't send again; contact us with your order number and transaction ID.

WhenAfter purchase

Log in to your page with the wallet you bought with and issue a connection code for the AI you want to use. No need to buy again. An AI you have already connected doesn't need the code every time.

WhenAfter purchase

Check whether you can restore the original wallet. If you lose your recovery information, identity checks become impossible and you may no longer be able to access your Access Pass. Never send your private key or recovery phrase, not even to support.

WhenWhen connecting your AI

A connection code can be used only once. Return to your page from “Already purchased,” issue a new code, and enter it only on your AI's authentication screen.
