Launch a real pair, step by step

  1. 01Top up both wallets with the amounts above.
  2. 02Open Launch and connect MetaMask (Side A), then Phantom (Side B). Approve the network switch to Robinhood Chain if asked.
  3. 03Enter name, ticker, description and image, and pick a fee model: Creator Fees or Automated Buyback.
  4. 04Check that every readiness item is green, then press Launch.
  5. 05Approve the MetaMask signature first. Twinx waits for Robinhood Chain to confirm.
  6. 06Approve the Phantom signature next. Twinx waits for Solana to confirm.
  7. 07If one side fails, only that side is retried — the confirmed side is kept.
  8. 08Open Dashboard and press “Read live sources now” to pull real prices, liquidity and volume for both tokens.

Fees and gas vary with network load; amounts above are estimates, except the Pons fee, which is read live at launch.
