Spark said eligible OKX users can subscribe to its USDT savings product inside the exchange app, with deposits routed on-chain through X Layer.
Key Facts
- Spark has made its Spark Savings USDT product available inside the OKX app, reaching exchange users who do not connect a wallet or bridge assets themselves.
- Deposits reach Spark Savings on X Layer, OKX's EVM layer-2 network, after the exchange aggregates them.
- Spark is launching the product in selected markets outside the European Union, subject to local requirements.
Spark, a digital finance protocol that allocates capital across on-chain markets, said Friday it has extended its Spark Savings USDT product into the OKX app, giving it a route to stablecoin balances already sitting on the exchange.
Users subscribe with Tether (USDT) through OKX On-chain Earn without separately connecting a wallet, bridging assets or interacting directly with DeFi applications, according to the companies. OKX aggregates those deposits and connects them to Spark Savings on X Layer, OKX's EVM layer-2 network.
How Spark Deploys the Deposits
Spark allocates the capital across approved venues including lending markets, liquidity provision, real-world assets and other credit strategies, within constraints its governance defines. The protocol describes the allocation as programmatic.
For every dollar deposited, Spark borrows an equivalent amount of USDS through the Sky Allocation System Primitive, providing 1:1 USDS backing inside the Spark Liquidity Layer, the company said. Spark said its security framework combines liquidity buffers, constrained capital movement and a layered structure designed to progressively absorb losses before they reach Spark Savings depositors, and that vault balances and allocation activity are visible on-chain.
Spark Savings held about $1.26 billion in total value locked at the time of writing, according to DeFiLlama, within a wider Spark operation that also includes the SparkLend lending market.

Where Spark Savings USDT Is Available
Spark Savings USDT will initially reach eligible OKX users in selected markets outside the European Union, subject to applicable local requirements.
Sam MacPherson, co-founder and CEO of Spark, said the integration "doesn't bring DeFi complexity into the CEX experience; it brings the benefits of DeFi behind a familiar CEX experience."
Spark said the launch forms part of a broader collaboration with the exchange, with further integrations under consideration.
The protocol follows Aave, which expanded to X Layer earlier this year, onto a network OKX built on Polygon's CDK to settle to Ethereum.
