Spark enhances security through the highest engineering standards and a large-scale bug bounty program, which is crucial for building trust in new platforms. Spark's partners include Symbiotic, Lido, Curve, Arbitrum, etc., showcasing strong cross-protocol collaboration capabilities that help improve liquidity and user stickiness. In contrast, Aave, while integrated with protocols like Lido, does not have the same ecological scalability as Spark. Compound relies more on its own protocol, while MakerDAO primarily operates around the DAI ecosystem with limited collaboration.
