Overview

• EIP-1559 fee burns have destroyed 5.3 million ETH, equal to roughly $20 billion in removed supply.
• Technical failures and user errors account for at least 913,111 ETH (about $3.43 billion) lost forever through mislaid keys, fat-finger transactions and buggy contracts.
• The 2017 Parity Multisig vulnerability alone locked 513,746 ETH across 178 wallets, amounting to $1.93 billion in inaccessible funds.
• Major incidents include Rain Lõhmus’s 250,000 ETH loss from misplaced keys and 60,000 ETH trapped by Quadriga’s faulty contract.
• Conor Grogan cautions that these figures are conservative estimates since many losses—such as forgotten Genesis wallets—cannot be definitively measured.
