2. Stargate Finance Dominates Bridging Volume

Stargate Finance is a prominent player in the crypto bridging space, dominating the bridging volume with over $2.3 billion per month. As one of the leading decentralized bridging solutions built by LayerZero, Stargate Finance allows users to move assets across different EVM-based chains securely and efficiently. The platform's user-friendly interface and robust security measures have contributed to its widespread adoption.

The next most popular bridging protocols include the zkSync Era Bridge ($1.25b), Arbitrum Bridge ($1b), Polygon POS Bridge ($775m) and Core Bitcoin Bridge ($487m). The popularity of these bridges highlights that most of the cross-chain bridging flows are between Ethereum mainnet and optimistic or zk-rollups like Arbitrum and zkSync.

3. Polygon Boasts the Highest Bridge TVL

Polygon has emerged as a leader in the crypto bridging space, boasting the highest bridge Total Value Locked (TVL) with over $2.8 billion in assets. In the past month alone, Polygon has seen deposits worth $917,342,998 and net flows of $172,740,8151. This significant activity on Polygon's bridge is a testament to the network's scalable and efficient infrastructure, which has attracted a wide range of DeFi projects and users.

4. USDC is the Most Popular Bridging Asset

USDC accounts for a staggering 98.62% of tokens bridged out of Ethereum. This dominance reflects USDC's stability and widespread acceptance as a trusted stablecoin. Being pegged to the US Dollar, USDC provides a stable and reliable medium for transferring value across different chains, making it the preferred choice for bridging activities.

The popularity of USDC in bridging underscores the importance of stablecoins in the decentralized finance (DeFi) space. It highlights the need for stability and trust in cross-chain transactions, attributes that USDC enables. The extensive use of USDC in bridging also points to the growing integration of traditional finance with decentralized systems, bridging the gap between fiat and crypto.

5. Crypto Bridge Hacks Exceed $2.6 Billion

Crypto bridge hacks have become a concerning issue in the decentralized finance (DeFi) space, with exploits and hacks resulting in over $2.66 billion in assets lost. These incidents have exposed various vulnerabilities in bridging protocols, ranging from private key compromises to flaws in protocol logic. Some of the largest bridge-related hacks include:

  • Ronin (23 Mar, 2022): $624 million lost due to private key compromise through social engineering.
  • Poly Network (10 Aug, 2021): $611 million lost due to an access control exploit in the protocol logic.
  • Binance Bridge (6 Oct, 2022): $570 million lost due to a proof verifier bug in the protocol logic.
  • Wormhole (2 Feb, 2022): $326 million lost due to a signature exploit in the protocol logic.
  • Harmony Bridge (23 Jun, 2022): $100 million lost due to private key compromise by an unknown method.

The alarming frequency and magnitude of these bridge hacks underscore the urgent need for robust security measures within the crypto bridging space. The diversity of techniques used by attackers highlights the complexity of securing cross-chain transactions.

Bottom Line

Cross-chain interoperability through crypto bridging has revolutionized the digital asset ecosystem in 2023, enabling seamless transactions and bolstering market efficiency and liquidity. Our insights reveal substantial growth in bridged assets, spearheaded by players like Stargate Finance and Polygon, along with the prevalence of USDC in bridging activities.

However, the alarming $2.66 billion in losses from bridge hacks emphasizes an urgent need for robust security. The trends and statistics explored here not only illustrate a dynamic and rapidly evolving space but also underscore the need for vigilance, transparency, and continuous innovation in decentralized finance.
