const quote = await fetch('https://1click.chaindefuser.com/v0/quote', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    dry: false,
    swapType: 'FLEX_INPUT',
    slippageTolerance: 100,  // 1% - allows slight amount variation
    originAsset: 'nep141:btc.omft.near',  // Bitcoin
    destinationAsset: 'nep141:wrap.near',
    amount: '100000000',  // 1 BTC in satoshis
    recipient: 'user.near',
    refundTo: 'bc1q...',  // Bitcoin refund address
  })
}).then(r => r.json());
```

```tsx
function PassiveDeposit({ quote, originSymbol }) {
  const { depositAddress, depositMemo, amountInFormatted, deadline } = quote.quote;

  return (
