Portal Debuts Solana Support with First Non-Custodial BTC-to-SOL Atomic Swaps on Mainnet.
San Francisco, 4 September 2025 – Portal to Bitcoin, a custody-less interoperability protocol for Bitcoin, has added Solana (SOL) as its first mainnet L1 integration for native BTC cross-chain swaps. The milestone enables trust-minimized, self-custodial SOL-to-BTC and BTC-to-SOL transactions while maintaining full user control from start to finish. Previously, Ethereum swaps were only supported on testnet, making Solana the protocol’s first fully live mainnet integration.
In parallel with the Solana integration, Portal to Bitcoin has secured a new $50 million ecosystem fund round led by Paloma Investments, bringing its total funding raised to $92 million. The capital will be used to scale developer support, deepen liquidity, and accelerate institutional onboarding as Portal advances toward its mainnet. The fund follows earlier backing from Coinbase Ventures, OKX Ventures, Arrington Capital, Republic Capital, and others.
With the Solana integration, users can move and swap native assets between Bitcoin, Solana, and Ethereum without relying on bridges, vaults, multisig intermediaries, centralized exchanges (CEXs), or wrapped derivative assets. This marks the first time a non-custodial mainnet transaction, a Bitcoin-to-Solana swap via the Portal Wallet and DEX has been processed directly between two blockchains. The protocol delivers a CEX-level user experience without sacrificing the security and self-sovereignty of self-custody. All swap transactions inherit Bitcoin-anchored security, with on-chain provenance available for verification on Solana Explorer. Portal’s cross-chain automated market maker (AMM) seamlessly powers liquidity between Bitcoin and other networks, free from custodians, bridges, centralized venues, or wraps.
“Our aim is simple: Bring native Bitcoin settlement to a multi-chain world,” said Dr. Chandra Duggirala, CEO and Founder of Portal to Bitcoin. “If you need a custodian, that’s off-chain, not cross-chain. With SOL support, traders can now move between Bitcoin and Solana with speed, low transaction fees and the self-sovereignty and finality they deserve; one that only trust-minimized atomic swaps provide.”
The rollout is underpinned by Portal’s newly launched BitScaler technology, designed for lightning-fast, cost-effective, and effectively limitless scalability across chains. By combining BitScaler with the protocol’s cross-chain AMM, Portal removes critical points of failure and streamlines execution for traders, developers, and integrators seeking native, on-chain settlement.
“Solana brings high-throughput UX; Bitcoin brings the world’s strongest settlement assurances, Duggirala added. “Portal unites those strengths without bridges, wraps, or custodians. Performance and security no longer sit on opposite sides of the table.”
The announcement comes as the project approaches its Token Generation Event (TGE) on September 3, 2025, providing the community with a timely utility milestone to engage with ahead of the listing. Developers and early users can try today on the Portal Incentivized Testnet V2.
