The global leader in crypto hardware wallets, Ledger, reaches a new milestone in its evolution by natively integrating OKX’s DEX (decentralized exchange) directly into its ecosystem. This strategic collaboration now allows users to swap tokens on-chain while maintaining the highest level of hardware security.
A Partnership Between Two Crypto Giants
This alliance unites two major players with complementary missions. On one side, Ledger, founded in 2014, has conquered the market with over 7 million devices sold worldwide, securing approximately 20% of global crypto assets, representing nearly $400 billion. On the other side, OKX stands as one of the world’s leading crypto platforms, and its DEX aggregates liquidity from over 400 sources across more than 25 blockchains.
Jean-François Rochet, Executive Vice President of Consumer Services at Ledger, emphasizes that this collaboration offers users « more competitive exchange pricing options, » while enabling OKX to reach a user base that prioritizes security and self-custody.
How Does This Integration Work?
The integration enables users to perform token swaps directly from their Ledger wallet without ever compromising the security of their private keys. Here are the key points:
- Mandatory hardware signing: every transaction must be confirmed and signed on the physical Ledger device, eliminating any risk of unauthorized execution
- Total self-custody: private keys never leave the device, removing counterparty risk associated with centralized platforms
- Multi-chain support: Ethereum, Arbitrum, Optimism, Base, Polygon, and BNB Smart Chain are supported at launch
- Best prices guaranteed: liquidity aggregation across 400+ DEXs enables the most competitive rates with minimal slippage
OKX DEX: Much More Than a Simple Decentralized Exchange
Unlike traditional DEXs, OKX DEX functions as a powerful aggregator that consolidates liquidity from hundreds of platforms to offer the best prices. Its API also integrates over 18 cross-chain bridges, including Stargate, Across, Celer cBridge, and SWFT, enabling seamless transactions between different blockchains.
This tool is already used by over 50 decentralized applications, including the renowned Zerion wallet, which confirms that the integration has significantly improved the trading experience by increasing token coverage across more than 7 chains.
A Well-Thought-Out DeFi Expansion Strategy
This integration is part of Ledger’s broader strategy to enrich the DeFi experience directly from its ecosystem. The manufacturer had already integrated the ParaSwap and 1inch aggregators, but the addition of OKX DEX significantly expands the range of accessible liquidity.
Ledger has also integrated the DeFi platform Zerion, offering a comprehensive dashboard to track and manage DeFi investments. This « all-in-one » approach reflects the manufacturer’s desire to become a complete gateway to decentralized finance while maintaining its unmatched hardware security standards.
Self-Custody: A Growing Trend
This announcement comes amid growing demand for self-custody solutions. The numbers speak for themselves: self-managed wallets represented 68% of crypto transactions in Q3 2025, and 48% of DeFi and NFT users consider self-custody an absolute necessity.
Several factors fuel this trend:
- Crypto hacks caused $2.2 billion in losses in 2024, a figure expected to exceed $2.37 billion in 2025
- Institutional multi-signature wallet deployments reached 9 million in 2025
- The use of threshold signature schemes increased by over 35% year-over-year
- Regulatory pressure is pushing 40% of custodial platforms to offer hybrid self-custody options
A Deepening Partnership
This is not the first collaboration between Ledger and OKX. As early as December 2022, OKX announced compatibility of its Web3 wallet with Ledger devices, particularly via Bluetooth with the Nano X. But today’s announced integration marks a turning point: it’s no longer simply about connecting a Ledger device to the OKX app, but natively integrating the DEX aggregation engine within the Ledger interface itself.
Toward a New Standard in Secure Trading
This alliance strengthens Ledger’s positioning as a complete digital asset management platform, far beyond simple cold storage. For OKX, it’s an opportunity to reach a community renowned for its caution and commitment to security.
With $600 million raised in total and continuous expansion of its services, Ledger continues to invest in innovation. According to CEO Pascal Gauthier, the company is expanding its scope from crypto security to the broader field of cybersecurity.
The boundary between « cold storage » security and access to decentralized protocols is gradually blurring. This trend, illustrated by the Ledger-OKX DEX partnership, could well redefine the standards of secure crypto trading for years to come, finally offering users the best of both worlds: maximum security and seamless access to DeFi.
