We monitor both tools around the clock for uptime, SSL validity, and response times. Three Sigma currently has a healthy health status with 100.0% uptime over the last 30 days. Zellic is rated healthy with 100.0% uptime. For any tool you trust with your funds, trades, or yield, uptime and speed are non-negotiable.
Three Sigma's key strengths include extensive audit track record with $10b+ protected, multi-chain rust expertise across solana, near, and polkadot. Zellic stands out for audited top-tier protocols (wormhole, pyth, layerzero), deep solana/rust expertise, thorough manual review process. On the flip side, Three Sigma's weaknesses include not exclusively solana-focused, while Zellic's main drawback is premium pricing for audit engagements.
