Cross-Chain Solutions Move Away From Bridges
A narrative is growing around the security risks of traditional bridges, with a focus on "bridgeless" alternatives. Pact Swap is being highlighted on social media for its bridge-free architecture that allows direct native asset swaps. Separately, a project named Beyond is connecting Bitcoin L1 to over 80 blockchains using LayerZero's OFT standard, which avoids wrapped or synthetic assets.
- Cross-chain bridge hacks have resulted in over $2.8 billion in losses, accounting for nearly 40% of all value stolen in Web3, highlighting the systemic risk of these protocols. High-profile examples include the $624 million Ronin Bridge exploit and the $326 million Wormhole hack, which often stem from compromised private keys or smart contract vulnerabilities. - Traditional bridges are prime targets because they create central points of failure; they often lock assets in a single smart contract or multi-sig wallet, which becomes a massive honeypot for attackers. The Ronin hack, for instance, occurred after attackers gained control of five of the nine validator keys, a vulnerability created by centralized validation. - LayerZero's Omnichain Fungible Token (OFT) standard works by burning tokens on the source chain and minting an equivalent number on the destination chain. This mechanism keeps the token's total supply constant and allows assets to exist as native tokens on multiple blockchains, rather than as wrapped versions that carry custodial risk. - Demonstrating growing adoption of this "bridgeless" model, BitGo, the primary custodian for Wrapped Bitcoin (WBTC), has adopted the OFT standard to make WBTC native across multiple blockchains, starting with Avalanche and BNB Chain. - Pact Swap operates on the Coinweb PACT framework, which uses "reactive smart contracts" to monitor and react to events on different blockchains without an additional consensus layer. This allows it to coordinate native asset swaps directly between chains. - To secure trades, every swap on Pact Swap is 2x over-collateralized and enforced by on-chain logic. If one party fails to settle, the system automatically compensates the other with the locked collateral, removing the need for intermediaries or external validators. - The Pact Swap protocol supports native, permissionless swaps across seven key networks: Bitcoin, Ethereum, BNB Chain, Litecoin, TRON, Dogecoin, and Polygon.
