Null Basket
Buy 2–5 assets across networks with one ETH funding transaction.
One payment, several assets
Choose 2–5 receiving assets, their percentage shares and full destination addresses. Start with native ETH on Base, Robinhood Chain or Arbitrum. Receiving assets come from the available exchange catalog; supported Robinhood stocks use an automatic final Uniswap swap.
Shares must total exactly 100%. Each leg must meet its provider minimum and have a live quote. Changing an asset clears its destination address to prevent sending on the wrong network.
Build a basket ↗Review, reserve, fund
- Connect the sending wallet. Receiving wallets do not need to connect.
- Request fresh quotes for the complete basket. Review every address, amount and network.
- Reserve all routes. If any route cannot be prepared, the app does not offer payment.
- Confirm one native ETH transaction. It distributes the exact amounts to the provider orders and pays the aggregate service fee.
Costs and staking
The Null Cash service fee is 0.5% of the ETH allocation, added on top. A verified sending wallet with a qualifying $250 stake can receive a 0% service fee quote. Provider costs remain included in the quoted outputs and source network gas is additional.
Stock outputs are estimates with a 1% slippage limit. A fixed provider quote does not fix the price of a subsequent stock swap. This feature does not promise investment returns or portfolio performance.
Track every part and recover
Keep the basket open for automatic status checks every 15 seconds. A provider-confirmed crypto delivery is labeled accordingly; automatic stock delivery requires its on-chain settlement event. Temporary status failures preserve the last result and never mark the basket complete.
Provider refunds go to your sending wallet. If a final stock swap cannot execute within its terms, the received ETH or WETH is returned to that leg’s destination after the delivery deadline. A completed part cannot be rolled back.
Saved baskets and templates are kept in this browser. Download the private receipt; its access key restores tracking on another device. Do not share the key publicly. Templates are not recurring orders: buying again always requires fresh quotes and another wallet confirmation.
