Spark just grew 28% in one day. Idle stablecoins are officially getting put to work.

Spark Liquidity Layer just hit $2.8B in TVL. Per DeFiLlama, that's a 28% jump in 24 hours, as of this morning.

The protocol doesn't hold money. It routes it. Spark automates where USDS, sUSDS, and USDC go: across chains, into DeFi protocols, into RWA venues, wherever yield is highest.

DeFiLlama categorizes Spark as an "Onchain Capital Allocator." That label has been small and niche for two years. A $2.8B layer posting 28% daily growth is not niche anymore.

Spark is Sky's routing arm. Sky, formerly MakerDAO, issues USDS. Spark puts it to work across the ecosystem. When that flywheel spins faster, the issuers who still rely on passive float start losing ground.

The dynamic is the same one that broke bank deposits in the early 1980s. Money market funds started routing idle cash toward T-bills instead of letting it sit in low-yield accounts. Banks held the float; funds put cash to work. Depositors moved.

Spark is running that same play. The economics are straightforward. Tether and Circle make billions on float. They hold T-bills; users hold stablecoins and collect nothing.

That model works when there's no alternative. Spark is the alternative. USDS and sUSDS holders can route into yield automatically, without leaving the stablecoin ecosystem. The free-money model now has a real competitor.

$2.8B isn't existential for Tether, which holds over $100B in reserves. But direction matters more than level. The 28% jump came from a single data source, so treat the exact figure carefully.

The category is scaling. The infrastructure is live. Investors who see the yield will use it.

You're leaving yield on the table if you hold USDS or sUSDS outside Spark. The routing is automated. That's the point.
