Purchasing a license

Node licenses are ERC-721 NFTs on the Arbitrum blockchain. This page covers platform navigation and the full purchase flow.

​

Before you start

Before purchasing a node license, make sure you have:

1. MetaMask installed and configured. You will use your connected wallet to complete the purchase.
2. MetaMask set to Arbitrum One. Node license purchases are performed on Arbitrum One.
3. Enough ETH on Arbitrum One to complete the purchase. ETH is used to pay for the license when ETH is selected as the payment currency.
4. A small amount of ARB on Arbitrum One for network fees.
5. Completed any required KYC/KYB verification. Purchase completion may require verification through the payment process.

After purchasing the license, you will need to import the NFT into MetaMask and bridge it to Autheo Chain. See License setup for the complete post-purchase flow.

​

Platform navigation

Once logged in, the main navigation is a tab bar at the top of the content area: The header includes the Autheo logo (returns to the Purchase page), links to the LitePaper and Autheo Explorer, social links, and your connected wallet address. On mobile, these are accessible via the hamburger menu (☰) in the top right.

Purchasing a node license

​

Step 1 — Choose a node type

Click the node type you wish to purchase to see the current price and available supply.

​

Step 2 — Configure your purchase

Quantity — Use the + and − buttons (or type directly) to set how many licenses to purchase. The maximum is governed by the per-user cap in the smart contract.

Network: Node license purchases are performed on Arbitrum One. Make sure your wallet is connected to the correct network before selecting a payment method.

Currency Promo / Referral code (optional) — Enter a referral code in the Promo Code field and click Apply to receive a discount and credit the referrer with a commission. Safety Fund (optional) — Enabling the Safety Fund checkbox allocates a small additional amount as a network safety reserve.

​

Step 3 — Confirm the purchase

1. Review the order summary and click Purchase
2. A Purchase Confirmation modal appears with a real-time transaction progress flow

For ETH / USDT / USDC payments:

1. Approve the transaction in your wallet. ERC-20 payments require a token approval before the purchase transaction can be submitted.
2. Confirm the purchase transaction in your wallet.
3. Pay the applicable network gas fees.
4. On success, you are redirected to the Success page.

For FIAT payments:

• You are redirected to a hosted payment page
• On successful payment, you are redirected to the Success page
• If you cancel, you are redirected to the Cancel page with no charge applied

Important: Do not close your browser or disconnect your wallet while a purchase transaction is in progress.

​

Supply limits and blacklist check

Each pricing tier has a fixed supply. When a tier sells out, it automatically advances to the next tier. Current supply availability is shown on the purchase page. If your wallet is on the Autheo blacklist, the purchase button will be disabled. Contact Autheo support if you believe this is in error.

​

After your purchase

After a successful purchase, you will see a transaction summary on the Success page. Your new license NFT will also appear in your wallet. Before you can use the license on Autheo Chain:

1. Import the NFT into MetaMask so that it is visible in your wallet.
2. Bridge the license NFT from Arbitrum One to Autheo Chain.
3. Verify the resulting license record on Autheo Chain.
4. Bind the license according to its license tier.
