San Francisco, September 4, 2025 – The portal to Bitcoin, a non-customized interoperability protocol for Bitcoin, has added Solana (SOL) as the first mainnet L1 integration of native BTC cross-chain swap. Milestones allow reliable, freestanding SOL-BTC and BTC SOL transactions while maintaining complete user control from start to finish. Previously, Ethereum Swap was only supported on testnets, so Solana became the first full live mainnet integration of the protocol.
Alongside Solana Integration, the portal to Bitcoin secured a new $50 million ecosystem fund round led by Paloma Investments, increasing its total funding to $92 million. Capital is used to expand developer support, deepen liquidity and accelerate agency onboarding as the portal moves towards the mainnet. The fund follows previous support from Coinbase Ventures, OKX Ventures, Arrington Capital, Republic Capital and others.
Solana integration allows users to move and exchange native assets between Bitcoin, Solana and Ethereum without relying on bridges, vaults, multisig intermediaries, centralized exchanges (CEXS), or wrapped derivative assets. This is marked only when exchanges for Bitcoin and Solana via portal wallets, and when Dex is processed directly between two blockchains. This protocol provides a CEX-level user experience without sacrificing self-reliant security and self-governance. All swap transactions can be used to inherit the security of Bitcoin Anchors and to verify on-chain sources in Solana Explorer. The portal’s cross-chain automatic market maker (AMM) seamlessly drives liquidity between custodians, bridges, centralized venues, or no wraps, and other networks.
“Our goal is simple: bringing native Bitcoin settlements to a multi-chain world.” I said Dr. Chandra Duggirala, CEO and Founder of Bitcoin Portal.“If you need custodians, it’s off-chain, not cross-chain. With Sols support, traders can now travel between Bitcoin and Solana with speed, low trading fees, and the self-strength and finality they deserve.
This deployment is supported by Portal’s newly launched Bitscaler technology, designed for fast lightning, cost-effective, and effectively for endless scalability across the chain. By combining Bitscaler with protocol cross-chain AMM, the portal removes key points of failure for traders, developers and integrators seeking native settlements in the chain.
“Solana brings high-throughput UX. Bitcoin brings the world’s strongest settlement guarantee. Duggirala has been added.“The portal combines these strengths without a bridge, a wrap or custodian. Performance and security are no longer sitting on the other side of the table.”
The announcement will be directed by the project token generation event (TGE) on September 3, 2025, providing the community with timely utility milestones to be involved prior to the listing. Developers and early users can try out the portal-incentived testnet V2 today.
About the Bitcoin portal
A portal is an unlawful infrastructure that allows for atomic swaps between bridges or other chains. Its technology stack includes Bitscaler, Portalos, Portal Wallet, Swap SDK, and Rafa-AI. The protocol is supported by Coinbase Ventures, Okx Ventures, Arrington Capital and others, with a total of tens of millions of funds (for example, $34 million was reported in early 2024).
