A Bitcoin user accidentally paid 1.60 BTC, worth about $102,800, in network fees after an automated replace-by-fee, or RBF, script malfunctioned, according to BlockBeats. The transaction did not send any BTC to the intended recipient. On-chain data shows it had a single input totaling 160,343,885 satoshis and an output value of zero, meaning the full amount was absorbed as miner fees. The transaction was included in Bitcoin block 962142 on Aug. 12. The reported issue stemmed from an automation script that raised the RBF fee once per second without a reasonable fee cap, allowing the fee to keep increasing until it consumed the entire input. SpiderPool mined the block, and the transaction accounted for 88% of the block’s roughly 1.82 BTC in total fees. The case highlights how misconfigured fee-bumping tools can produce extreme outcomes on-chain within a short period.

A Bitcoin user paid 1.60 BTC in network fees, worth about $102,800, after an automated replace-by-fee (RBF) script malfunctioned, according to BlockBeats. No BTC was sent to the recipient in the transaction.

On-chain records show the transaction was included in Bitcoin block 962142 on Aug. 12. It had a single input totaling 160,343,885 satoshis, with an output value of zero, leaving the entire amount to be collected by miners as fees.

The issue came from an automated fee-bumping script

The reported cause was an automation script that increased the RBF fee once every second without a reasonable upper limit. As the fee kept rising, it gradually consumed the full input amount.

The transaction made up about 88% of the block’s total fees

The block was mined by SpiderPool. Based on the disclosed figures, this single transaction contributed 88% of the block’s roughly 1.82 BTC in total transaction fees.
