Why a DeFi platform ditched its consumer app to become the secret backend for tech giants

Spark, a DeFi protocol affiliated with the Sky ecosystem, has abandoned its consumer-facing app to focus on providing backend liquidity and yield infrastructure for major fintech platforms. By leveraging Uniswap v4 hooks and strategic partnerships, Spark aims to become the primary layer for stablecoin interoperability as the market becomes increasingly fragmented.
Why it matters
This shift highlights a broader trend in the crypto industry where DeFi protocols are pivoting from direct-to-consumer competition toward B2B infrastructure roles to capture institutional-scale volume.
Fintechs, exchanges and banking groups are increasingly launching their own dollar-linked tokens. Each issuer wants to keep users, reserves and transaction activity inside its own network as competition ramps up.
The stablecoin landscape "is about to fragment more and more," Sam MacPherson, CEO of Phoenix Labs, said in an interview with CoinDesk.
PayPal has PYUSD, Circle has USDC, and Tether has USDT. Robinhood has joined the Global Dollar (USDG) consortium and is building its own chain, while OpenUSD (OUSD) is another large consortium that includes Stripe and Coinbase.
Beyond these giants, there are hundreds of other stablecoins, including Ethena's USDe, World Liberty Financial's USD1 and Sky's USDS.
The result is liquidity scattered across an expanding number of tokens and networks.
Spark is betting those networks will still need to connect. Its aim is to be the layer that moves money between them.
