How to deposit and withdraw

Everything happens on the app page. You need a wallet, some USDG, and a little ETH on Robinhood Chain for gas.

Before you start

• A wallet. MetaMask, Rabby, Coinbase Wallet, or any WalletConnect-compatible wallet.
• USDG on Robinhood Chain. The only token the vault accepts is the official one, listed below.
• A small amount of ETH on Robinhood Chain to pay gas. Transactions usually cost a fraction of a cent.

Network details

The app offers a one-click switch. If your wallet asks you to add the network manually, use these official values:

Deposit, step by step

1. Open the app and connect your wallet. Check that the site address in your browser is the one linked from @CrumbRH.
2. Switch network if asked. A red banner appears when your wallet is on another chain; one click switches it to Robinhood Chain.
3. Enter an amount, or press MAX to use your whole wallet balance (or whatever room the vault caps leave).
4. Tick the box confirming you understand that the yield and the crumbs are simulated.
5. Confirm the approval in your wallet. The app requests an allowance for the exact amount you typed, never an unlimited one. Your wallet shows the amount; check that it matches.
6. Confirm the deposit in your wallet. This is the transaction that moves your USDG into the vault.
7. Watch the status. Each step shows "confirm in your wallet", then "pending", then "confirmed" or "failed", with a link to the transaction on the explorer.

Your deposited balance updates, and the simulation panel switches from preview to live data computed from your on-chain deposit.

Withdraw, step by step

The withdraw panel is always on the page, directly under the deposit panel. It is never hidden, disabled by the team, or subject to a timer.

1. Enter an amount and press "Withdraw amount", or just press "Withdraw everything".
2. Confirm in your wallet. One transaction, no approval needed.
3. Done. The USDG is back in your wallet as soon as the transaction confirms. No fee is taken.

Withdrawing without this website

Your funds do not depend on this site being online. If it ever disappears, open the CrumbVault contract on the block explorer, go to the write tab, connect your wallet and call withdrawAll(). That is the entire recovery procedure.

Troubleshooting

• "You rejected the request". You closed or declined the wallet prompt. Nothing was sent; try again.
• The approval confirmed but the deposit failed. Your USDG never left your wallet. The unused allowance is for that exact amount only; press deposit again and the app will reuse it.
• The deposit button says the cap is reached. The vault was deployed with immutable safety caps. They limit new deposits only; withdrawals always work.
• Balances show a dash. The RPC could not be reached. Your funds are unaffected; the app retries on its own.
