According to Foresight News, Mempool has announced that F2Pool has refunded the overpaid transaction fee of 19.82108632 BTC to Paxos. Previously, Foresight News reported that on September 11, a Bitcoin transaction with a payment fee worth over 19 BTC (more than $500,000) occurred. Paxos later claimed responsibility for the transaction fee exceeding 19 BTC (over $500,000), stating that it had 'overpaid the Bitcoin network fee on September 10, 2023'. The reason for the overpayment was a bug affecting a single transfer, which has since been fixed.
