In the thirteenth installment of its "Deconstructing DeFi" series, Stabull Labs, through Co-CMO Jamie McCormick, detailed the three primary groups of participants generating its growing non-user interface (non-UI) trading volume: bots, solvers, and aggregators. The analysis explains why this volume is persistent and not tied to speculative trading or short-term incentives.
Bots are identified as the first layer of execution, operating continuously to scan for narrow, mechanical opportunities like price discrepancies and arbitrage windows. They are drawn to Stabull pools because the pools' oracle-anchored pricing closely tracks off-chain reference rates, offers predictable slippage, and enables atomic execution. This results in frequent, small trades that provide consistent fee generation and signal to liquidity providers that the liquidity is "working."
Solvers operate one layer above, optimizing entire transactions across multiple venues for best execution, gas efficiency, and atomic settlement. They choose Stabull pools for their reliability, price alignment, and deterministic execution, often using them as intermediate conversion steps or stable FX anchors. Once a solver approves a pool, it can be reused automatically across many transactions, leading to compounded volume.
Aggregators, like OpenOcean which has completed a custom integration on Base, abstract the complexity for end-users. They query multiple pools and assemble multi-leg routes. Stabull pools are increasingly included in these calculations not for deepest liquidity, but for stable pricing, lower failure rates, and clean integration into complex paths. Once integrated, volume through aggregators becomes continuous and UI-agnostic.
The interaction between these actors is layered and synergistic: aggregators rely on solvers, solvers deploy bots, and bots test liquidity. Stabull sits beneath all three as stable execution infrastructure. This pattern means volume growth is gradual then accelerating, driven by becoming embedded as useful DeFi infrastructure rather than marketing campaigns. Consequently, non-UI volume is steadier, more durable, and tied to real economic activity.
