Just tried out @sparkdotfi on @Optimism and @unichain_xyz and I’m genuinely impressed. This is way more than just another DeFi expansion — this feels like the beginning of something huge for Ethereum’s Superchain vision. Let me explain why 👇 With the launch of sUSDC and sUSDS, Spark is bringing native yield to stablecoins across chains. You can now deposit regular USDC or USDS into Spark Savings Vaults and receive sUSDC or sUSDS — both of which automatically accrue yield over time. No staking, no locking. Just earn. What makes this different? It’s the Spark Liquidity Layer (SLL). This layer ensures you can always redeem your yield-bearing stablecoins for the underlying asset plus yield — instantly, with zero slippage. That’s a game-changer for stablecoin utility and trust.

sUSDC is also a major evolution in the centralized stablecoin model. Instead of just sitting idle, your USDC now earns by default and remains usable across DeFi protocols. Yield-bearing collateral that’s composable = real capital efficiency. And this is just the beginning. Spark is laying down infrastructure for native chain interoperability. Soon, you’ll be able to deposit on one chain and earn on another — meaning true liquidity abstraction across Ethereum rollups. That’s the power of the Superchain. To support this, Spark has received 2M $OP from the Optimism Grants Council. A significant part of this is going to users through Spark Rewards and the upcoming Superstack XP campaign (Velodrome, Uniswap v4, and more). I’m farming sUSDC and sUSDS already, and will be closely watching the next wave of Superchain-native tools being built. This is what real multi-chain coordination looks like — not isolated ecosystems, but a unified, modular Ethereum.
