For Bitcoin-native applications that want to give BTC holders trading and money-market lending across 18+ networks, self-custodied from entry to settlement, with no wrapping and no centralized exchange in the middle.
The Partner
Bound (formerly radFi) is full-stack DeFi built natively on Bitcoin. Users trade, borrow, and earn from a single self-custodial account, with no KYC, no bridges, and no liquidations. Through Bound, holders trade crypto majors like ETH, SOL, BNB and USDC alongside RWAs, with atomic on-chain settlement secured by their own keys.
The Challenge
Bitcoin holds around 60% of the crypto market with over $1.5 trillion in market cap, but less than 1% of that supply is active in DeFi today. Builders bringing BTC on-chain have faced two compromises:
Wrapping the asset, which introduces a custodian between the user and the underlying Bitcoin (wrapped BTC alone accounts for over $8 billion in TVL).
Routing through a centralized exchange, which adds custody, latency, and counterparty exposure to what should be a self-custodied trade.
Bound's settlement architecture solves custody on the Bitcoin side, but reaching liquidity across every other network would have meant building cross-network execution infrastructure from scratch.
The Solution
Bound integrated the SODAX SDK to expose native Bitcoin across 18+ networks through a single intent-based execution call.
1
Sub-Block Settlement, Full Custody
Bitcoin-side settlement runs on a two-of-two multisig trading wallet that lets solvers treat a transaction as final at the moment of broadcast, settling end to end in approximately one minute.
2
Liquidity Across 18+ Networks, Out of the Box
A single SDK integration exposes native BTC across Ethereum, Solana, Arbitrum, Base, Avalanche, Sui and more.
3
No Wrapper, No Centralized Hop
Native BTC moves into and out of Bound without WBTC, without a centralized exchange round trip, and without bridge custody.

First to Market
The partnership made Bound first to market with native Bitcoin inside a cross-network execution system.

"Bringing native BTC trading directly against assets like ETH and SOL isn’t just an incremental improvement, it’s a new primitive. This integration with SODAX sets the foundation for the fastest native BTC-to-anything trading experience in the industry"
