Sei Network integrates USDC and Circle’s CCTP V2, boosting its DeFi, payments, and cross-chain capabilities.
Author: Chirag Sharma
July 11, 2025 — Sei Network just leveled up. The high-speed Layer-1 blockchain has officially integrated Circle’s USD Coin (USDC) and Cross-Chain Transfer Protocol V2 (CCTP), as confirmed by Circle and the Sei Development Foundation on July 10.
This integration means native USDC is now live on Sei. No more routing through IBC bridges like Noble. Developers can access plug-and-play stablecoin liquidity with fully reserved, dollar-backed USDC directly issued by Circle, the issuer of the world’s largest regulated stablecoin.
CCTP V2 eliminates friction between chains by allowing users to burn and mint USDC across supported blockchains, enabling seamless flows between Sei, Ethereum, Solana, and others. The move aligns Sei with Circle’s global vision and opens the door to faster payments, improved DeFi, and scalable institutional use cases.
The timing couldn’t be better. Sei’s network activity in 2025 has gone parabolic:

With over 200 live apps and growing DeFi traction, Sei is now one of the most active chains. USDC’s arrival strengthens its appeal for developers and institutions alike—especially as Sei was shortlisted by the Wyoming Stable Token Commission to support the WYST stablecoin, giving it a U.S. regulatory edge.
Circle’s support brings credibility, especially amid U.S. Senate advancements like the GENIUS Act, which provides clearer guardrails for stablecoins.
Before this move, Sei’s stablecoin landscape was dominated by community-driven tokens like SEIYAN. But USDC changes the game. X posts show a 300% increase in stablecoin usage on Sei since 2024, and USDC is already outpacing other options in liquidity and user preference.
As performance upgrades like Giga Sei aim for 100,000 transactions per second and major partnerships (Coinbase, Circle) continue stacking, Sei is positioning itself not just as a high-performance chain—but as a true cross-chain payment and DeFi hub.
