# Spark on Supersmooth (stablecoin liquidity from Sky reserves)

> Spark is a lending market built by the Sky ecosystem with direct access to Sky balance-sheet liquidity. Supersmooth integrates all four automations on Ethereum Mainnet.

Spark is a lending market built by the Sky ecosystem, formerly MakerDAO, with direct access to Sky's balance-sheet liquidity. That access is why Spark USDS and DAI borrow rates are often the most stable and competitive available. On Supersmooth, Spark supports all four automations and is frequently the best venue for stablecoin-debt Multiply positions and sUSDS-adjacent yield loops.

## Overview

SparkLend is a pooled-liquidity money market technically derived from Aave v3 under license. Supersmooth uses Spark for Borrow, Multiply, and Yield Loop positions on Ethereum Mainnet. Because Spark stablecoin liquidity comes directly from Sky reserves, rates are set by governance rather than by utilization spikes, producing predictable carry for multiplied strategies.

| Networks | Ethereum Mainnet |
| Supersmooth automations supported | Stop Loss, Trailing Stop Loss, Auto Sell, Auto Take Profit |
| Liquidity model | Unified pooled liquidity |
| Liquidation style | Partial liquidation via close factor (same as Aave v3) |
| Governance | Sky DAO |

## Origin and timeline

Phoenix Labs launched Spark in 2023 as the MakerDAO lending frontier, technically derived from Aave v3 under license. Spark became part of the Sky ecosystem rebrand in 2024, and the SPK token launched in 2025 with staking, points, and rewards programs following. Spark describes itself as a two-sided capital allocator: on one side Spark borrows from Sky stablecoin reserves and deploys across DeFi, CeFi, and real-world assets; on the other side Spark packages that yield into user products. The three Spark pillars are Spark Savings, which covers sUSDS and savings vaults; SparkLend, which is the money market Supersmooth integrates; and the Spark Liquidity Layer, which provides direct liquidity into DeFi markets and is an evolution of the [MakerDAO D3M](https://github.com/sky-ecosystem/dss-direct-deposit).

## Design tradeoffs

* **Sky-backed stablecoin liquidity:** SparkLend stablecoin borrow liquidity comes directly from Sky reserves, with rates set by governance rather than by utilization spikes. This produces predictable carry for multiplied strategies, but rates move by governance decision.
* **Aave v3 mechanics:** Spark uses the same partial-liquidation and E-mode machinery as Aave v3, so risk behavior is familiar.
* **Coverage:** Spark on Supersmooth is Ethereum Mainnet only, and Spark asset selection is narrower than Aave's.

## Spark on Supersmooth

Supersmooth integrates Spark with all four automations. Spark is frequently the best venue for stablecoin-debt Multiply positions and sUSDS-adjacent yield loops.
