Aave Deploys on OKX's X Layer, Bringing $47B DeFi Protocol to Exchange's Users

Aave, the decentralized lending protocol with approximately $47 billion in total deposits and around 60% market share in DeFi lending, has launched on X Layer, OKX's Ethereum-compatible Layer 2 blockchain, the companies announced in a statement today.

OKX Wallet users can now supply assets, borrow against collateral, and earn yield directly on the network without bridging to a separate chain or using an external interface.

The deployment is running on Aave v3.6, the protocol's most capital-efficient version, and supports a range of assets at launch including USDT0, USDG, GHO, xBTC, xETH, xSOL, and liquid staking derivatives. Users can borrow at up to 88% loan-to-value ratios on certain liquid staking pairs through Aave's efficiency mode – meaningfully higher than the standard 70% threshold.

X Layer itself warrants some context. Built using Polygon's Chain Development Kit and connected to Polygon's AggLayer – a shared liquidity and interoperability layer linking multiple CDK-powered chains – X Layer launched on public mainnet in April 2024 as OKX's attempt to bring its centralized exchange user base onchain. In August 2025, OKX completed a major upgrade to the network, boosting throughput to 5,000 transactions per second, burning 65 million OKB tokens to cap supply at 21 million, and formally positioning X Layer as the primary settlement and DeFi layer within the OKX ecosystem. OKB serves as the network's native gas token. In March 2026, Intercontinental Exchange – parent of the NYSE – made a strategic investment in OKX valuing the company at $25 billion, giving the broader ecosystem a significant institutional endorsement.

The Aave deployment is notable for the friction it removes. Historically, an OKX user wanting to access DeFi lending would need to withdraw funds from the exchange, set up a separate wallet, bridge to a supported chain, and navigate Aave's interface independently. The X Layer integration collapses that into a single workflow within OKX Wallet, with tokenized supply positions — aTokens — tradeable directly on OKX's DEX without manually unwinding positions first.

The timing is deliberate. Last week's passage of the Digital Asset Market Structure Act in the US House provided the clearest regulatory framework for DeFi protocols operating in the US market to date, and Aave's X Layer deployment is among the first high-profile protocol moves made in its wake.

Aave Labs founder Stani Kulechov said the deployment extends Aave's liquidity to "a growing ecosystem of users and applications" and flagged further integration across OKX's product suite ahead.
