<p><code>fallbackfee</code> takes a fee rate as a parameter, not a boolean. The fee rate is denominated in BTC/kvB. For a 1 sat/byte fee rate, you would do <code>fallbackfee=0.00001</code>.</p>

`fallbackfee` takes a fee rate as a parameter, not a boolean. The fee rate is denominated in BTC/kvB. For a 1 sat/byte fee rate, you would do `fallbackfee=0.00001`.
