Millions in Crypto Unclaimed in Forgotten Bridge Contracts, Arkham Intelligence Reveals

Arkham Intelligence, a crypto analytics firm, has uncovered a surprising trend in the world of decentralized finance (DeFi) - millions of dollars worth of cryptocurrencies are languishing unclaimed in various bridge contracts. These funds, belonging to both prominent crypto personalities and lesser-known entities, have been stuck for periods ranging from several months to over two years. The issue stems from the difference in operation between cross-chain bridges and native bridges, where the latter requires manual retrieval of funds, leading to situations where users have forgotten about their assets. Notable cases include a wallet linked to Vitalik Buterin with over $1 million stuck in the Optimism bridge for over seven months, Bofur Capital with $1.8 million stuck in the Arbitrum bridge for 27 months, and even Coinbase with $75,000 in unclaimed USDC via the Optimism bridge. Arkham has identified dozens of accounts with six to seven-figure sums stuck in bridge contracts, forgotten by their owners, prompting the firm to urge individuals and entities to revisit their transaction histories and bridge activities to ensure all assets are accounted for.

Arkham Intelligence Reveals Millions of Dollars in Unclaimed Crypto Assets Dormant in Bridge Contracts

In a startling revelation, Arkham Intelligence, a leading crypto analytics firm, has uncovered an alarming trend in the decentralized finance (DeFi) landscape: vast sums of cryptocurrencies, amounting to millions of dollars, are languishing unclaimed in various bridge contracts. These funds, belonging to both prominent crypto personalities and lesser-known entities, have been trapped for extended periods, ranging from several months to over two years, highlighting the prevalent oversight and potential risks associated with bridge contract usage.

Cross-Chain Interoperability and Bridge Contracts

DeFi bridge contracts play a crucial role in the interoperability of blockchain networks, enabling the seamless movement of assets and data between different ecosystems. However, not all bridges operate in the same manner. While cross-chain bridges automatically transfer users' assets to the target chain, native bridges require manual retrieval of funds. This distinction has led to a situation where users have inadvertently forgotten about their assets, leaving them dormant in these contracts.

Notable Cases of Unclaimed Assets

Among the most noteworthy cases identified by Arkham is a wallet linked to Ethereum co-founder Vitalik Buterin. This wallet, which received 50 Ether (ETH) from Buterin himself, has amassed over $1 million worth of assets trapped in the Optimism bridge for more than seven months. Although this amount represents a relatively small portion of Buterin's estimated $789 million cryptocurrency portfolio, it underscores the magnitude of the issue.

Other prominent entities affected by this phenomenon include Bofur Capital, potentially related to a Celsius creditor, which has $1.8 million in wrapped Bitcoin (WBTC) stuck in the Arbitrum bridge for 27 months. An NFT user known as Mike Macdonald appears to have forgotten about claiming approximately $117,000 in assets linked to CryptoPunks sales on a bridge contract.

The list of affected wallets extends far beyond these high-profile cases. Arkham has identified dozens of accounts with six to seven-figure sums forgotten in bridge contracts. One such example is a wallet with the ENS name thomasg.eth, which has left approximately $800,000 in the Arbitrum bridge for nearly two years.

Coinbase Implicated

Even major cryptocurrency exchanges like Coinbase have fallen victim to this trend. Arkham reported that Coinbase attempted to bridge $75,000 in USD Coin (USDC) to Ethereum via the Optimism bridge six months ago, but the funds remain unclaimed on Ethereum's base layer.

Oversight and Forgotten Assets

While it is conceivable that some wallet owners have intentionally parked their funds in these bridge contracts, the sheer scale and duration of the unclaimed assets imply that many users have simply forgotten about them. The decentralized and often complex nature of DeFi protocols and bridge contract interactions may have contributed to this oversight.

Call to Action

Arkham Intelligence has issued a stark warning to individuals and entities involved in DeFi to thoroughly review their transaction histories and bridge activities to ensure that all assets are accounted for. The firm has taken the initiative to notify the owners of the identified wallets, reminding them of the potential millions of dollars they may have misplaced.

Implications and Recommendations

This revelation underscores the importance of responsible asset management in the DeFi space. Users should be aware of the implications of bridge contract usage and the potential risks associated with manual retrieval of funds. It is crucial to maintain meticulous records of all transactions and bridge activities to avoid inadvertently forgetting about or losing access to valuable assets.

To mitigate the risks associated with bridge contracts, users are advised to consider the following recommendations:

• Carefully review bridge contract functionality and ensure full comprehension before using them.
• Maintain accurate records of all transactions and bridge activities.
• Set reminders or conduct regular audits to ensure that assets have been claimed promptly.
• Consider using cross-chain bridges that offer automated or simplified retrieval mechanisms.

By adhering to these guidelines, users can safeguard their assets and prevent them from falling into the forgotten realm of bridge contract purgatory.
