SODAX and Bound Make Native Bitcoin Tradeable Across 18 Networks Without Wrapping

For Bitcoin holders who have avoided DeFi over custodial risk, the SODAX-Bound integration offers a new path: native BTC across 18 networks, self-custodied from entry to settlement.

ZUG, SWITZERLAND, May 27, 2026 — SODAX, the cross-network execution and liquidity system coordinating settlement across blockchain networks, today announced that native Bitcoin is available to application developers through the SODAX SDK. Through an infrastructure partnership with Bound (formerly radFi), any application across 18 blockchain networks can integrate SODAX to offer its users trading and money market lending or borrowing with native Bitcoin, without wrapping the asset or routing through a centralized exchange.

Bitcoin holds around 60% of the crypto market with over $1.5 trillion in market capitalization. But less than 1% of that supply is currently active in DeFi, according to DefiLlama data. As Bitcoin’s network was not originally designed to host smart contracts, DeFi builders integrating BTC have typically faced two compromises: wrapping the asset, which introduces a custodian between the user and the underlying Bitcoin, or routing through a centralized exchange, which adds custody, latency and counterparty exposure to what should be a self-custodied trade. Wrapped Bitcoin alone currently accounts for over $8 billion in TVL.

“ Bitcoin has been the most-watched asset in crypto for 15 years and one of the least useful inside DeFi. The largest asset in the room was the one builders kept asking us about,” said Min Kim, founder of SODAX.

Sub-Block Settlement, Full User Custody

The SODAX SDK exposes native Bitcoin across 18 blockchain networks, including Ethereum, Solana, Arbitrum, Base, Avalanche and Sui, through a single intent-based execution call. Bitcoin-side settlement is handled by Bound, which operates a two-of-two multisig trading wallet architecture that lets the SODAX Solver, the execution coordination layer that finds and fills cross-network trades, treat a Bitcoin transaction as final at the moment of broadcast, allowing trades to settle end-to-end in approximately one minute. The user retains custody of their Bitcoin throughout; the multisig configuration expires by default after a period of inactivity, returning the keys fully to the holder if Bound is no longer in use.

Wallets, decentralized exchanges and lending protocols already integrated with the SODAX SDK gain native BTC support automatically with the latest SDK update.

“SODAX gives us the liquidity infrastructure across 18 networks out of the box. We focus on the user experience; SODAX handles the execution. That is why this partnership has allowed us to land first to market with native Bitcoin inside a cross-network execution system,” said Scott Smiley, co-founder of Bound.

Native Bitcoin in DeFi has become an active category. Chainflip and THORChain offer native BTC trading as consumer products. Babylon, Stacks and OpNet are working to extend what is possible on Bitcoin itself. SODAX’s position is different by design: a developer integration surface rather than a destination, with native Bitcoin as a primitive inside wallets, DEXs and lending protocols across 18 networks.

Three Integration Paths for SDK Partners

The native Bitcoin primitive reaches builders through three integration patterns. For wallet integrators, users can hold, exchange and use native BTC as collateral from within the existing application. For DEXs and aggregators, native BTC is addressable from every supported network, with quotes returned through the SODAX Solver and settlement handled atomically. For money markets and lending protocols, native BTC becomes a borrowing asset without requiring users to wrap the collateral first.

The integration surface does not change for builders already on the SDK. Both Bound and SODAX have noted publicly the intention to extend it further into Bitcoin-native Runes, including community memecoins and ordinals-adjacent assets, opening cross-network access to a class of trading flows that today require Bitcoin-native venues.

About Bound

Bound is full-stack DeFi built natively on Bitcoin. Users can invest, borrow, and earn from a single self-custodial account. No KYC, no bridges, no liquidations. Through Bound you can trade crypto majors ( ETH, SOL, BNB, USDC) and RWAs with atomic on-chain settlement, secured by your own keys.

About SODAX

SODAX is infrastructure for modern money. It is a cross-network execution and liquidity system that coordinates financial actions across 18+ networks, including Ethereum, Solana, Arbitrum, Base, Avalanche, Sui and more.
