Unraveling the Mystery Behind the Largest-Ever Bitcoin Transaction Fee
- Bitcoin user inadvertently pays a historic $3 million transaction fee, overshadowing the previous record.
- User claims to be a victim of hacking, creating a new account and disclosing the incident.
- Cryptocurrency community scrutinizes verification, mining details, and explores possible causes as Mononaut advises enhanced security measures.
In a groundbreaking event last week, a Bitcoin user inadvertently paid a staggering $3 million transaction fee, catapulting the incident into the annals of cryptocurrency history. The sheer magnitude of the fee not only raised eyebrows but set a new record for the highest transaction fee ever recorded.
The colossal transaction fee reported by The Block amounted to 83.65 BTC, surpassing $3.1 million. This accidental payment dwarfed the previous record fee of $500,000 witnessed in September. Following the transaction, the user took swift action, creating a new X account and publicly disclosing the extraordinary incident.

Verification and Mining Details
To substantiate ownership claims, the user signed a message from the Bitcoin address, a move validated by both Mononaut and Jameson Lopp. However, this verification comes with a caveat—a potential compromise of the wallet, leaving room for an alternate, malicious signer.
The transaction was processed by AntPool in block 818,087, adding a layer of complexity to the unfolding narrative. Drawing parallels to a previous record fee incident in September, involving Paxos and F2Pool, AntPool’s response remains shrouded in mystery, with no public comments to date. Adding to the intrigue, a community member, “niftydev,” has offered testimony, claiming personal knowledge of the account owner.
Possible Causes, Analysis, and Lessons
The incident prompts speculation on the vulnerability of a low-entropy wallet, susceptible to hacking due to insufficient randomness. Additionally, the use of replace-by-fee (RBF), a Bitcoin protocol feature allowing fee adjustment on unconfirmed transactions, is considered a contributing factor. Multiple attackers vying for stolen funds through automated scripts add another layer of complexity.
Mononaut’s evaluation focuses on the vulnerability of low-entropy wallets and unveils insights into an automated script theory, explaining the correlation between the 60% fee and the total amount stolen. As a reflection on the incident, a stern reminder emerges—to avoid shortcuts with entropy. Mononaut advocates for enhanced security measures, recommending the use of multisig for large sums to mitigate future risks.
