Stablecoin liquidity management is becoming a systems discipline. Spark has moved more than $370M in stablecoin volume through @Uniswap v4 over the last 2 days and $1.5B in the past 30 days as part of active inventory management. In much of the market, that kind of rebalancing still runs on manual execution as conditions move. It caps how fast positions respond and how tightly rates hold. The Spark Liquidity Layer runs it as one programmatic system across all Savings products and chains. It keeps target buffers in each vault for instant withdrawals and uses signed intents for larger redemptions. Inventory can then be rebalanced across venues through ALM controlled execution. On Uniswap v4, that clears permissionlessly and atomically. That is what allocators weigh when choosing who to trust with stablecoin liquidity.
