Circle Internet Group's Arc Network is gaining attention as a potential key growth catalyst for the company. The network, which aims to make digital payments faster and more secure, began its public testnet in the third quarter of 2025 with over 100 major partners, including AWS, BlackRock, Mastercard, and Visa, participating in the testing phase. The Arc Network is intended to be a foundational layer for internet finance and is planned for a full commercial launch in 2026. The company also intends to launch a native token to support the network's growth. Analysts see the success of the Arc Network, which is still in development, as a crucial element in Circle's strategy to bridge traditional finance with blockchain technology.
