Unlike traditional finance, where banks can reverse mistaken transactions, crypto offers no such safety net. In the decentralized world of Ethereum, once a transaction is confirmed on the blockchain, it is permanent and irreversible.
How Much Ethereum Has Been Lost?
According to Conor Grogan, Director at Coinbase, over 913,111 ETH—worth approximately $3.4 billion at current prices—has been permanently lost due to human and technical errors. This staggering figure represents around 0.76% of Ethereum’s total circulating supply, currently standing at 120.7 million ETH.

Why Is Ethereum Lost?
A significant amount of Ethereum has been lost due to three main reasons.
- Wrong address transfers: where users mistakenly send ETH to incorrect or non-recoverable addresses. This includes typos, sending funds to contract addresses not designed to receive them, or using incompatible blockchain networks.
- Smart contract vulnerabilities. Bugs or coding errors in smart contracts can lead to funds being locked, redirected, or exploited, often permanently, with no way to recover them.
- Multisig wallet failures. If a multi-signature wallet is misconfigured, destroyed, or if the required keys are lost, the ETH stored becomes permanently inaccessible.
Notable Ethereum Loss Incidents
| Incident | ETH Lost | Cause |
| Parity Wallet Bug | 306,000 ETH | Contract destroyed due to bug |
| QuadrigaCX | 60,000 ETH | Poorly managed wallets after CEO’s death |
| Akutars NFT | $34M in ETH | Two smart contract bugs |
| Burn Address Mistakes | ~25,000 ETH | Sent to unrecoverable addresses due to typos |
Can Lost Ethereum Be Recovered?
No. Due to Ethereum’s immutable blockchain design, once ETH is sent to an invalid or inaccessible address, it cannot be retrieved. There is no central authority to reverse or recover funds.
Grogan believes the actual number of lost Ethereum may be much higher than $3.4 billion, as many incidents go unreported or unnoticed.
