Circle has launched the second version of its Cross-Chain Transfer Protocol (CCTP V2) on Polygon's Proof-of-Stake (PoS) network, enabling fast, capital-efficient, and seamless cross-chain USDC transfers. The upgrade eliminates the need for wrapped assets or third-party bridges by allowing native USDC settlement with 1:1 burn-and-mint mechanics, enhancing speed and composability for developers and users. Polygon’s recent Heimdall v2 upgrade further supports this by providing faster finality, allowing users to withdraw POL tokens from centralized exchanges such as Binance and Bitget in approximately two minutes. Additionally, Circle is expanding its native USDC and CCTP offerings to the Sei Network, a fast and cost-efficient Layer 1 blockchain, where it is also a lead investor. This expansion aims to promote efficient stablecoin usage across multiple blockchain ecosystems.
