The user's risk score (1–10) selects one of three tiers. All three share the same optimizer; they differ only in which vaults are eligible and how concentrated the result may get. Every number below is read straight from the allocation code. | Parameter | Conservative | Balanced | Aggressive | | ------------------- | --------------------- | ------------------------------- | ---------------------- | | Risk-score band | 1–3 | 4–7 | 8–10 | | Min Atlas Score | 70 | 55 | 40 | | Min TVL | \$50M | \$10M | \$1M | | Min audits | 2 | 1 | 1 | | Min track record | 90 days | 30 days | none | | Assets | Stablecoins, ETH, BTC | + curated yield-bearing dollars | + long-tail USD tokens | | Max withdrawal wait | Instant only | ≤ 10 days | ≤ 30 days | | Max per vault | 35% | 35% | 35% | | Max per protocol | 50% | 60% | 50% | | Max per chain | 60% | 60% | 60% | | Positions | 3–5 | 3–6 | 3–8 | | Risk-aversion λ | 0.1–0.5 | ≈0.9–2.0 | ≈4.7–10 | λ is the risk-aversion dial handed to the optimizer, set on a continuous 0.1–10 scale by the exact risk score; the ranges shown are what each tier's band maps to. A higher λ leans harder away from volatility. Caps and thresholds are allocation policy, not the scoring math.
