Cosmax is building AI agents that read markets, optimize with quantum-inspired solvers and act only inside limits your own account enforces, with custody secured by post-quantum signatures. Built natively on Robinhood Chain.
Each module runs on your Cosmax Account, a smart account on Robinhood Chain. Your assets stay in it; agents only get scoped, expiring keys.
The guardrail layer, live on Robinhood Chain. Your Cosmax Account holds the funds. Each agent gets its own key with an expiry date, an allowlist of contracts and functions, approved counterparties, and per-call and 24-hour caps for ETH and each token. Anything outside the rules reverts, and one switch pauses every agent.
The strategy engine. AI research agents turn market data into views, Black-Litterman blends them with market-implied equilibrium returns, and a quantum-inspired QUBO solver (simulated annealing) picks the weights. Every run is benchmarked against a standard mean-variance optimization, and the solver inputs, seed and weights are signed so anyone can re-run it. Rebalances execute through the Firewall.
The custody layer. Vault withdrawals are authorized with stateful hash-based signatures (LMS/XMSS, as specified in NIST SP 800-208), whose security rests only on hash functions and is not broken by known quantum algorithms such as Shor's. The contract records every one-time key index it has accepted and rejects reuse. Hybrid mode requires both ECDSA and post-quantum signatures; large withdrawals wait behind a timelock.
Connect to read your account straight from the chain, then run your agents from the Agent Firewall tab. Viewing never asks for a signature.
