OKX brings USDT yield to 100M+ users with Morpho on Katana

OKX has been methodically expanding beyond spot and derivatives trading into a full-stack crypto platform. The exchange already offers a noncustodial Web3 wallet supporting 130+ chains, a DEX aggregator, an NFT marketplace. The trajectory is clear: OKX wants to be the platform where users trade, hold, earn, borrow, and interact onchain, all without leaving the OKX platform.

Yield on idle holdings is one of the most persistent demands from exchange users. OKX already offered centralized earn products, but the next frontier was onchain yield, transparent, noncustodial, and sourced from real borrowing demand rather than opaque internal loan books.

The opportunity was to build a lending product that plugs directly into an established lending network with existing borrower demand, professional risk curation, and battle-tested infrastructure, while keeping the OKX user experience intact.

OKX integrated Morpho on Katana to power its USDT Onchain Earn product, with yield coming from a Gauntlet-curated USDT vault.

The user flow is deliberately simple. No wallet setup, no bridging, no gas management. OKX abstracts the entire onchain complexity while keeping the yield source fully transparent.

Under the hood, the Gauntlet curated USDT vault allocates deposits across a selection of liquid collateral markets on Katana to optimize risk-adjusted yield. The vault follows Gauntlet’s CORE risk framework, the same methodology behind $1.6B+ in assets curated across Morpho.

This architecture gives OKX exactly what it needed: day-one access to a mature lending market with real borrowing demand, professional risk management, and the ability to offer competitive rates without originating a single loan. OKX focused on building a seamless abstraction layer for its users. Morpho and Gauntlet handled the lending infrastructure and risk curation.

The market response was immediate. Within the first week of launch, nearly $290M in USDT flowed into the Gauntlet-curated vault on Morpho, making it one of the fastest-growing vault DeFi Mullet integration.

Beyond the headline deposit figure, the integration plugs into Katana’s VaultBridge: a mechanism that puts bridged assets to work rather than letting them sit idle in a standard L1 bridge contract. Assets bridged to Katana are deployed into low-risk Morpho vaults on Ethereum L1, and the yield generated is routed back to Katana as additional incentives for DeFi markets, including the very vault that OKX deposits into.

This creates a compounding flywheel: more OKX deposits, more assets flowing through VaultBridge, more yield generated on L1, stronger incentives on Katana, better rates for OKX users, and more deposits. VaultBridge provides a recurring, non-inflationary reward stream that scales with TVL.

OKX joins Coinbase, Crypto.com, Bitget, Binance, and a growing list of major exchanges and fintechs that have integrated Morpho as their onchain yield infrastructure. The pattern across these integrations is consistent: exchanges own the user relationship and distribution; Morpho provides the noncustodial, composable, and transparent lending infrastructure.
