2025-07-21 07:42:09

Main Idea

Coinbase director Conor Grogan reports that 913,111 ETH, worth $3.4 billion, has been permanently lost due to user errors, representing 0.76% of the total ETH supply.

Key Points

1. A total of 913,111 ETH (0.76% of supply) is lost forever due to user errors like incorrect address transfers, smart contract mistakes, or failed multisig wallets.

2. Examples include the Parity wallet incident (306,000 ETH frozen) and QuadrigaCX's undocumented wallets (60,000 ETH lost).

3. The Akutars NFT project lost $34 million due to smart contract bugs during a Dutch auction mint.

4. Grogan notes 25,000 ETH was sent to burn addresses, but the $3.4 billion estimate likely undercounts losses (excludes lost private keys).

5. Around 5.3 million ETH has been burned since EIP-1559's implementation in 2021.
