According to industry reports, Bitcoin cross-chain protocol Portal raised $25 million in funding on December 4, 2025. Investors in this round include JTSA Global and others. Following this latest round, Portal’s cumulative funding has reached $117.5 million.Portal is a non-custodial Bitcoin interoperability protocol focused on enabling efficient connectivity across the Bitcoin ecosystem. Through technical innovation, the protocol facilitates fast, low-cost atomic swaps of native Bitcoin assets—such as BTC, Ordinals, and Runes—between Layer 2 and other Layer 1 networks, eliminating the need for traditional cross-chain bridges or token wrapping. This design significantly reduces both the complexity and risk associated with cross-chain operations, opening new possibilities for the development of the Bitcoin ecosystem.Since its inception, Portal has maintained steady fundraising progress. The project completed an $8.5 million pre-seed round in September 2021, followed by a $34 million seed round in January 2024. In August 2025, Portal secured an additional $50 million in funding. Meanwhile, the project’s token, PTB, was officially listed for trading on September 3, 2025, marking a new phase in ecosystem development. This $25 million funding round will further accelerate Portal’s technology development and market expansion, supporting the robust growth of the Bitcoin cross-chain ecosystem.
