SODAX and radFi Make Native Bitcoin Tradable Against Ethereum, Solana, and USDC

The radFi-SODAX integration bypasses Bitcoin block confirmations to deliver the fastest native BTC to cross-network asset trades available today, settling in under one minute.

ZUG, SWITZERLAND,March 19, 2026 — radFi, the Bitcoin-native trading protocol that launched in summer 2025, has integrated the SODAX SDK to launch cross-network trading routes for native Bitcoin. radFi users can now exchange their BTC directly for Ethereum, Solana, or the USDC stablecoin. They can do it without converting Bitcoin into a substitute token and routing through a centralized exchange. It also doesn’t require transferring assets’ custody to a third party, at over 10 times faster than the network average.

Moving value from Bitcoin to other networks has historically required either accepting a “wrapped” version of BTC. It is a stand-in token that a third party issues and controls on another network, or routing through a centralized exchange. Both approaches mean trusting an intermediary with the underlying asset. The radFi integration, powered by the SODAX Solver, replaces that process with direct, intent-based cross-network execution: users specify what they want to trade and the system handles settlement across networks automatically.

radFi-SODAX Partnership Unlocks Fastest Native BTC Cross-Network Trading

“Partnering with SODAX allows radFi to extend Bitcoin-native trading beyond a single ecosystem,” said Scott Smiley, co-founder of radFi. “By integrating the SODAX SDK, we’re unlocking direct BTC trading against assets like ETH, SOL, and USDC, without sacrificing the speed and user experience radFi users expect.”

The partnership facilitates the fastest native BTC to cross-network asset trading experience currently available. Most cross-network Bitcoin trades require at least one full block confirmation. That takes an average of 10 minutes on the Bitcoin network. Besides, the time can rise with network congestion, block size limits, and fee dynamics. 

The radFi-SODAX integration instead requires zero block confirmations, achieving finality at the moment of broadcast through radFi’s trading infrastructure. In testing, trades have settled in under one minute. By comparison, leading alternatives for native Bitcoin trading clock in at 27 minutes for the same route.

“This integration sets the foundation for the fastest native BTC-to-anything trading experience in the industry,” Smiley said.

Three Trading Routes Live at Launch

The integration opens three trading pairs on day one. radFi users can now exchange native Bitcoin for native Ethereum, the second-largest cryptocurrency by market value, and native Solana. They can also trade Bitcoin for USDC, a dollar-denominated stablecoin used widely for payments and DeFi activity. 

In all three cases, real Bitcoin on the Bitcoin mainnet is exchanged against the real asset on its home network. The SODAX Solver coordinates execution across both sides of the trade.

radFi is built primarily around Bitcoin Runes. It is a token standard that allows digital assets to be issued and traded directly on the Bitcoin mainnet. The SODAX integration lays the groundwork for that ecosystem’s expansion. While the initial routes cover BTC only, cross-network trading for Rune-based assets is planned for a future phase of integration.

SODAX Adds Bitcoin to Its 17-Network Execution System

For SODAX, the partnership marks the first time native Bitcoin has entered its cross-network execution system. It spans 17+ networks, including Ethereum, Solana, Arbitrum, Base, Avalanche, and Sui. 

radFi integrated the SODAX SDK directly, following the same path as Houdini Swap, Amped Finance, Hana Wallet, and Balanced. Through that integration, radFi gains access to unified cross-network liquidity coordination. That also without building or maintaining that infrastructure independently.

“We’ve always believed in a cross-network future,” said Min Kim, founder of SODAX. “As new networks keep emerging, fragmentation is only accelerating, and there aren’t enough players on the interoperability side to service all of them. Native Bitcoin entering the SODAX execution system is a significant step toward the unified financial infrastructure we’re building.”

The three launch routes represent the initial phase of the integration. Additional trading pairs are planned as the partnership develops, with the potential for Rune trading to extend across networks through the same execution system. The integration also lays the groundwork for native Bitcoin to become accessible to builders through the SODAX SDK across all 17+ supported networks.

The integration is live now at radfi.co. Builders interested in adding cross-network capabilities to their own applications can find documentation at docs.sodax.com.
