Portal to Bitcoin Raises $25M for Atomic OTC Trading Desk

The $25 million funding round, announced on Thursday, underscores growing institutional interest in building advanced financial rails atop Bitcoin. While JTSA Global led the investment, the round also saw participation from established crypto venture capital firms including Coinbase Ventures, OKX Ventures, and Arrington Capital. This consortium of backers signals strong confidence in Portal to Bitcoin’s technical approach and its market positioning within the competitive landscape of cross-chain solutions.

The funding is earmarked to support the operational launch and scaling of the company’s newly deployed Atomic OTC desk. By securing this level of capital, Portal to Bitcoin is positioned to aggressively develop its protocol and attract institutional traders seeking secure, large-scale settlement options. The involvement of entities like Coinbase Ventures and Arrington Capital, known for their strategic bets on foundational crypto infrastructure, adds considerable credibility to the venture’s ambitions.

At the core of Portal to Bitcoin’s new service is the use of Hashed Timelock Contracts (HTLCs) to enable atomic swaps. This technology allows for the “instant, trustless cross-chain settlement of large block trades” by ensuring that either both legs of a trade execute simultaneously or neither does, effectively eliminating counterparty risk. This is a critical innovation for over-the-counter markets, where trades are traditionally bilateral and reliant on trust or escrow services.

The platform’s OTC desk is specifically designed for sizable transactions that could otherwise move markets on public order books. By facilitating direct, peer-to-peer swaps that settle atomically, the service removes the need for intermediaries, reducing costs and settlement times while enhancing security. This model directly addresses a key pain point for institutional players in the crypto space who require execution certainty for large orders across different blockchain assets.

Portal to Bitcoin enters a market with established players like THORChain and Chainflip, which also offer cross-chain atomic swap capabilities. However, the protocol distinguishes itself by adopting a distinctly Bitcoin-centric philosophy. Its architecture is built natively for Bitcoin interoperability, drawing parallels to more focused systems such as Liquality and Boltz. This specialization on the Bitcoin network could appeal to a purist segment of the market that prioritizes security and simplicity.

The announcement positions the Atomic OTC desk as a tool for “Bitcoin-native interoperability,” suggesting a vision where Bitcoin itself becomes a settlement layer for multi-asset trades without wrapping or bridging assets to other ecosystems. This approach contrasts with some competitors that operate their own independent networks or liquidity pools. By leveraging HTLCs directly, Portal to Bitcoin aims to provide a more minimalistic and secure trust model, appealing to those who want to minimize smart contract risk and interact primarily through the Bitcoin protocol.

The successful $25 million fundraise and product launch indicate that venture capital sees ample room for specialized solutions within the broader cross-chain narrative. As the crypto market matures, the demand for secure, efficient, and trustless settlement mechanisms for large-scale capital movements is only likely to increase, making infrastructure plays like Portal to Bitcoin critical components of the future financial stack.
