DeFi Execution Engine

Context

A small, crypto-native trading desk wanted to scale its DeFi strategies beyond manual MetaMask clicks and brittle scripts.

They were already profitable, but the operational reality looked like this:

• Multiple browsers and wallets open at once
• Ad-hoc scripts glued together across chains
• No single place to see position/risk in real time
• Missed opportunities whenever network conditions changed quickly

Objectives

• Turn chaotic DeFi flows into a cohesive, observable execution system
• Reduce failed transactions and overpaying for gas
• Make it safe to scale strategies without scaling operational stress

Solution

Sybil Solutions, led by 0xSero, built a DeFi execution engine that sits between strategy logic and on-chain protocols:

• Unified execution API:
  • Normalized interactions with DEXes, routers, and bridges
  • Abstracted chain-specific quirks, so strategies stay focused on logic, not plumbing
• Real-time routing:
  • Smart routing across DEXes and liquidity pools
  • Price impact / slippage checks before every on-chain call
• Risk and guardrails:
  • Per-strategy and global limits on size, exposure, and retry behavior
  • Circuit breakers for abnormal volatility or oracle divergence
• Operational observability:
  • Live dashboard for fills, errors, gas usage, and PnL context
  • Structured logs that can be piped into the client’s existing monitoring stack

Results

After rollout and tuning:

• Daily on-chain volume scaled to $2.5M+ across several chains
• Failed transaction rate dropped below 1.5% despite volatile market conditions
• Gas costs were reduced by ~40% via batching, routing, and parameter tuning
• The team was able to launch and retire strategies faster, with much clearer risk bounds

Stack & Implementation Notes

• Smart contracts: Solidity, battle-tested interfaces, and conservative upgrade paths
• Off-chain: Node.js / TypeScript orchestration with typed contracts
• Data: Price + liquidity feeds from multiple oracle and DEX sources
• Infra: CI/CD pipelines for simulation, dry-runs, and canary deployments

How This Reflects Sybil / 0xSero

This project is emblematic of how Sybil Solutions approaches Web3: treat DeFi as a real production system—with proper engineering, safety rails, and clear feedback loops—without losing the ability to move quickly when the opportunity is there.
