Advanced + CEX

A route with a CEX exchange step#

Advanced + CEX connects the selected assets through a centralized exchange provider. It can add separate wallet swaps where an asset is not offered directly. “Advanced” describes routing flexibility; it is not a promise of a better rate, faster execution or stronger privacy for every pair.

The provider quote is floating-rate. The estimated receiving amount can change before settlement because of execution price and route costs. Always review the amount again after a source wallet swap.

When both assets are directly supported#

1. Select the sending and receiving assets, their networks and an amount above the quoted minimum.
2. Enter the receiving wallet and a refund wallet you control. Both addresses are validated for their selected networks.
3. Select Review route. Read the estimated receiving amount and any route notices.
4. Create the order after review. Save its ID and receipt before payment.
5. Fund the order on the sending network while its deposit window is open. Follow the order’s exact instructions.
6. Track the provider’s progress and the actual receiving transaction.

For example, ETH on Robinhood can be exchanged for ETH on Arbitrum. The symbol stays ETH while the funds move to a different network. This route still has provider costs and source gas.

When your source asset needs Uniswap#

For a supported stock or token, the app first checks a token → ETH Uniswap V3 route on that asset’s chain. It also checks the provider leg and receiving address before offering the first wallet transaction.

1. Connect the wallet holding the source token and switch to its network.
2. Approve the required token amount, then confirm the source swap. Some tokens require an allowance reset before the approval.
3. Wait for the swap receipt. The ETH output remains in your source wallet.
4. The app reserves ETH for gas and requests a fresh provider quote based on the actual swap output.
5. Review again, create the provider order and fund it separately.

If the provider is unavailable after the first swap, your ETH stays in your wallet. You can request a new quote later. Do not repeat a source swap whose transaction is already submitted.

When your destination asset needs Uniswap#

New Advanced orders use a dedicated, recipient-bound execution address on supported networks. The provider sends ETH there; the server then executes Uniswap V3 and sends the selected token directly to the destination address. The recipient can be another person’s wallet and never needs to connect or sign.

The final swap has a 1% minimum-rate limit relative to the reviewed quote, scaled to the actual ETH payout. Null Cash pays execution gas. Processing continues when the browser is closed, and Transactions shows completion only after the final token transfer is confirmed.

If the swap cannot satisfy the reviewed terms within one hour of order creation, the ETH received is returned to the fixed destination address; an address that rejects ETH receives WETH instead. Save the receipt: it also contains a permissionless recovery transaction usable after that deadline. This is not an atomic cross-chain transaction.

Provider completion and actual delivery#

For supported native ETH payouts and native SOL, the app checks the receiving chain before displaying Funds delivered · verified on-chain. A provider’s completed flag can arrive before an independently readable receipt.

Direct ETH verification checks the network, successful receipt, transaction hash, destination and value. Contract-batched transfers may need tracing that this verifier does not provide. Other assets can show Provider reports completion; use the explorer and your wallet to check the actual asset.
