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 composable native USDC transfers across chains without the need for wrapped assets or third-party bridges. The upgrade offers developers and users benefits such as near-instant cross-chain USDC settlement, smart contract hooks for post-transfer actions, and a 1:1 burn-and-mint mechanism that eliminates reliance on liquidity pools. Following this, Circle has also introduced native USDC and CCTP V2 on Sei Network, a fast and cost-efficient Layer 1 blockchain. This integration is fueling increased stablecoin volume, decentralized finance (DeFi) growth, and bullish momentum for Sei, which has seen its token price surge by 113% in a month and recently hit $0.35. Sei Network is positioning itself as a cross-chain liquidity hub for DeFi, gaming, and payments, supported by Circle's early investment and integration. Additionally, Sei has been recognized by Wyoming as a candidate for the US's first official stablecoin pilot, and its token has an ETF filed in the US and an exchange-traded product (ETP) live in Europe. Sei is currently the second-largest EVM chain by users and holds about one-third of the market share in its segment.
