Your first paid call in three steps

Each step checks your wallet as you go, so you can see exactly what is left to do. Building an agent instead? Start with the developer guide or the MCP server.
  1. 1

    Connect a Solana wallet

    Any Solana wallet works: Phantom, Solflare, Backpack or another browser or mobile wallet. Shadealpha only reads your address and balances.

  2. 2

    Hold some USDC

    Skills are paid in USDC on Solana. Most calls cost less than one cent, so a dollar goes a long way. You don't need SOL: Shadealpha pays the network fee for every payment.

    Buy USDC on an exchange and withdraw it to your address on the Solana network, or swap for it inside your wallet. Before you send, check the token mint below: it is the only USDC Shadealpha accepts.

  3. 3

    Call your first skill

    Open a skill, tick the confirmation and press Pay. Your wallet shows one USDC transfer for the exact price; you approve it, and the result comes back with its Solana transaction.

Shadealpha never holds your funds and never asks for your seed phrase or private key. Every payment is signed in your own wallet, for the exact amount shown, and you are responsible for it. Terms
