Ethereum’s $23B Ghost Ledger: Lost, Burned, or Just Lost? 💸

by

Coinbase Head of Product Conor Grogan has revealed that at least 913,111 Ethereum worth $3.43 billion has been permanently lost due to user errors. 🤷‍♀️💸

Summary

  • 913,111 ETH worth $3.43b is lost forever due to user mistakes and contract bugs 😅
  • Parity Multisig bug in 2017 caused the biggest loss, locking over $1.9b in ETH 🧠💥
  • Total ETH destroyed, including EIP-1559 burns, exceeds 5% of all ETH created 🧙‍♂️🔥

The analysis reveals that 0.76% of ETH’s total supply has been destroyed due to various technical errors and protocol vulnerabilities. 🕵️‍♀️

When including EIP-1559 burned Ethereum (ETH) totaling 5.3 million tokens, over 5% of all Ethereum ever created has been permanently removed from circulation, representing $23.42 billion in destroyed value. 💸

Parity Multisig bug leads largest single Ethereum loss

The 2017 Parity Multisig library vulnerability, which permanently locked 513,746.47 ETH worth $1.93 billion across 178 wallets, is the source of the most significant individual loss. 🧨

An anonymous user exploited a vulnerability in the shared library component and subsequently destroyed it. This blocked access to funds in 587 dependent wallets. 🧠

The Web3 Foundation accounts for 306,000 ETH trapped in this incident, while other organizations and individuals lost additional funds through the same exploit. 🧙‍♂️

Based on my research, a minimum of 913,111 Ethereum is lost forever due to user error. This is 0.76%+ of ETH supply, or $3.43 billion in lost funds 😅

If we include EIP‑1559 burned ETH (5.3M), then >5% of all ETH ever made ($23.42B) have been permanently destroyed — Conor (@jconorgrogan) July 20, 2025

Other major losses include 250,000 ETH worth $939.7 million lost by Rain Lohmus due to misplaced private keys, and 85,476.17 ETH valued at $321.3 million locked in buggy contracts including Splitter and AkuAuction deployments. 🧠

Grogan’s research identified 36,419.23 ETH, worth approximately $136.9 million, sent to addresses through typing errors or “fat-finger” transactions across 2,639 wallets. 😅

These losses occur when users enter recipient addresses incorrectly, resulting in funds being sent to uncontrolled or non-existent addresses. 🧠

An additional 26,814.16 ETH valued at $100.8 million has been sent to burn addresses (0x0 and 0xdead), with users apparently intentionally destroying tokens for unknown reasons. 🧙‍♂️

The research also found 654.29 ETH, worth approximately $2.5 million, trapped in wrapped ETH contracts due to technical issues. 🧠

Actual losses likely exceed documented amounts

Grogan stressed that the $3.4 billion figure “significantly undershoots the actual lost/inaccessible ETH amount” because it only includes cases in which Ethereum is permanently locked. 🤷‍♀️

The analysis excludes lost private keys, forgotten Genesis wallets, and other forms of inaccessibility that cannot be definitively measured. 🧠

The documented losses provide a conservative baseline for Ethereum permanently removed from circulation through technical failures rather than intentional burning mechanisms. 🧙‍♂️

Lost private keys from early adopters and exchange failures likely contribute additional billions in inaccessible ETH. 🌌
