The Autheo Node Sale Platform is a decentralized application where you purchase node licenses represented as ERC-721 NFTs on the Arbitrum blockchain. Each license grants its holder the right to participate in the Autheo network — either by operating a validator node or delegating stake to earn rewards. Platform URL: https://tsp.autheo.com

Connect your wallet

  1. Click Connect Wallet
  2. A wallet selector modal appears — choose MetaMask or Trust Wallet
  3. Your wallet extension opens and prompts you to connect your account. Approve the connection.
  4. You will be asked to sign a message in your wallet. This is a Sign-In With Ethereum (SIWE) authentication step — it does not cost gas and simply proves ownership of your wallet address.
  5. Review the message content and click Sign in your wallet.
Upon successful sign-in, you are automatically redirected to the Purchase page.Connect wallet step 1 — wallet selector modalConnect wallet step 2 — wallet extension approvalConnect wallet step 3 — SIWE signature request
About SIWE authentication — Autheo uses Sign-In With Ethereum (EIP-4361) for login. No password is required. Your wallet signature proves your identity. The sign-in message is human-readable and shown in your wallet before signing. The signature only authorizes a session — it does not transfer funds or approve on-chain actions.
If you close the wallet popup or reject the signature request, the login will not complete. Try again by clicking Connect Wallet. To disconnect, click your wallet address in the top-right corner of the header. You will be logged out and redirected to the login page.
