SwapWidget

Trade BTC and ETH from your own wallet, with exchange-style tools: stop-losses, a level map, and a safety check on every swap.

Works with ETH, USDC and cbBTC (Coinbase's Bitcoin token) on the Base network.

Stop-losses from your own wallet

Set a stop-loss, take-profit or limit order on BTC or ETH. Our server watches the price day and night, and your phone signs the trade when it's on.

A level map for your stops Pro

See support, resistance and how far the price usually moves in a day, plus where a stop belongs. Set that stop in one tap.

A safety check on every swap

Before your phone signs, our server checks the swap quote. It can spend only the coin and amount you chose; if it asks for more, there's nothing to sign.

We never hold your key

How stops work

  • Our server checks your stop-losses, take-profits and limits about every 25 seconds.
  • When one is hit, your phone gets an alert and signs the swap from your wallet, as long as it's online and you're signed in. Tap Stop swap on the alert to cancel before the trade is sent.
  • Phone off? Nothing trades, and that stop is used up, so set it again. An alert that arrives more than 2 minutes late is skipped, so a stop can't sell long after it fired.

On both plans, SwapWidget takes 0.2% of each swap, 0x (the swap service behind every trade) takes about 0.15%, and the Base network fee is a few cents. The swap screen shows each fee before you confirm; widget buttons and stops pay the same fees without showing them.
