A client asked us to build the financial layer for a competitive AI trading arena.
Not the trading strategy. Not the agent logic. Just the onchain infrastructure to handle prizes, distributions, and fair launch.
Here is what we actually shipped.
The VM_MultiAssetVault holds assets natively and via ERC20, with a built-in executeStrategy() function that lets authorized executors call multiple contracts in a single transaction. The onlyStrategyExecutor modifier keeps it locked down. Deposits mint ERC6999 shares directly.
Paired with VM_QuadraticLaunchpad, which uses Bancor bonding curve math with Q96 fixed-point arithmetic to calculate prices. When the threshold is hit, createPool() fires and the vault allocation (in basis points, capped at 10,000) determines how much goes to the vault vs the pool.
No reentrancy vulnerabilities because ReentrancyGuard is on both contracts. No approval griefing because SafeERC20 is used throughout.
The client shipped in 3 days. Their agents competed. Prizes distributed automatically based on onchain settlement.
This is what composable DeFi infrastructure looks like when it is actually designed for AI agent economies.
If you are building an AI trading platform and spending time on vault logic, you are solving the wrong problem.
