LND Lightning Network Software Adds Cap on External Bitcoin Fee Estimates

WHY IT MATTERS

Think of Bitcoin transaction fees like postage for sending a letter. You need to pay a fee to get your transaction processed by the network. Lightning Network software like LND sometimes asks outside services how much that postage should cost. The problem is, sometimes those outside services might give a wildly high estimate, like being told a stamp costs $100 instead of $1. This new feature acts like a price ceiling, telling the software to never pay more than a certain amount no matter what the outside estimate says. For anyone running a Lightning node, this kind of safeguard helps prevent accidentally spending too much on fees, which is especially important since these processes often run automatically without a human checking each transaction.
