Helix Yield Vaults
ERC-4626 yield aggregator with auto-compounding strategies and slippage-bounded rebalancing.
Helix routes deposits into whitelisted strategies with harvest windows, slippage caps, and per-strategy debt ceilings - presenting one vault interface while keeping accounting isolatable per strategy.

Representative technologies from the delivery-not an exhaustive inventory of every dependency or internal tool.
Challenge
Compounding across thin DEX liquidity had to remain bounded: failed harvests could not strand funds, and strategy exits had to unwind without blowing pegged-asset pools.
Approach
ERC-4626 vault shells with strategy adapters in Solidity, Chainlink or TWAP-bounded pricing for rebalances, Foundry fuzz on share conversion invariants, and Arbitrum-first deployment for gas realism.
Outcome
Placeholder programme narrative - verify before publish. Stated headline: $140M TVL across 12 strategies with zero strategy-level loss events across 11 months.
