# Deposit & withdraw

Fund the primary Flips wallet on Robinhood Chain, or bridge ETH out.

The trade ticket spends **ETH already on Robinhood Chain**. Deposit is how it gets there. Withdraw is the reverse.

## Deposit

Open **Deposit**. Three paths:

1. **Direct send** — copy the primary address and send ETH that is already on chain 4663. Mainnet ETH to this address is the wrong chain.
2. **Buy ETH** — on-ramp into the Flips address when Account funding is enabled on the Privy app.
3. **Bridge** — from a connected wallet on Ethereum, Base, Arbitrum, Optimism, Stable, or Solana via Relay.

Change the receiving address on [Wallets](/docs/wallets). Direct sends always go to the **primary**.

## Withdraw

Open **Withdraw**.

- Bridge ETH off Robinhood Chain to another supported chain.
- Or send ETH to any 4663 address.

You sign. Flips never holds the keys. Relay quotes can include an app fee when a recipient is configured; if it is not, there is no extra app take on the bridge.

## Activity

Deposit and Withdraw both show recent bridge activity for the primary address. A pending bridge is not a failed trade. Do not retry a swap because a bridge is still settling.

## Common mistakes

- Sending Ethereum-mainnet ETH to the Flips address and expecting the ticket to unlock.
- Bridging to a wallet that is not the primary, then wondering why Pulse still shows zero.
- Treating a Relay origin confirmation as a Robinhood Chain credit. Wait for the destination tx.
