# Fund MNT wallet

> Top up the bot's MNT wallet — it pays the on-chain builder fees on Mantle.

Each user gets an **MNT wallet** that pays the bot's **on-chain fees on Mantle** — the gas for
committing the strategy before a trade and attesting the verified outcome after, plus the small
builder fee per closed episode. Keep a little MNT in it so launches and closes can write their proofs.

<Steps>
  <Step title="Open your wallet">
    In the bot, tap **👛 Wallet**. It shows your MNT address and balance, e.g.
    `MNT wallet: 0.8943 MNT — pays fees`.
  </Step>

  <Step title="Open the faucet (testnet)">
    Tap **💧 Top up**. The bot opens the **Mantle Sepolia faucet**
    (`https://faucet.sepolia.mantle.xyz`) and shows your address to paste.
  </Step>

  <Step title="Claim testnet MNT">
    Paste your wallet address into the faucet and claim. It pays your builder fees on Mantle.
  </Step>

  <Step title="Re-check">
    Back in the bot, send `/wallet` (or tap **🔄 Refresh**) — your new balance should show.
  </Step>
</Steps>

<Note>
  This is **testnet MNT** on Mantle Sepolia (chainId 5003). It only covers the bot's on-chain proof
  fees — it is not your trading capital (that stays on Bybit). Low on MNT? Just `/topup` again.
