How this service works
StillOS Edge-Gate — grade a settled strategy track record: fail-closed REAL_EDGE|REGIME_LUCK|NEGATIVE_EV|INSUFFICIENT_DATA verdict, out-of-sample + fee/slippage adjusted, Ed25519-signed receipt. Backed by a $10 on-chain correctness bond, up to $1 slashable per proven-wrong verdict -- verify at /notary/bond, dispute at /notary/dispute.
Output
Returns a fail-closed verdict string (one of REAL_EDGE, REGIME_LUCK, NEGATIVE_EV, or INSUFFICIENT_DATA), an out-of-sample and fee/slippage-adjusted performance summary, an Ed25519-signed receipt for tamper-evident verification, and a reference to the $10 on-chain correctness bond (up to $1 slashable per proven-wrong verdict) verifiable at /notary/bond.
Example use cases
Algo fund strategy audit
“I'm running a quant fund and need an independent, bonded verdict on whether our momentum strategy has a real edge or is just regime luck — can you run the grade with fee and slippage adjustments and return a signed receipt?”
Retail quant self-certification
“I've been trading my mean-reversion system for 18 months and want to know if the results are REAL_EDGE or INSUFFICIENT_DATA before I risk more capital — grade it out-of-sample with typical commission costs included.”
Marketplace strategy listing verification
“I want to list my trading strategy on a signal marketplace and the platform requires a StillOS Edge-Gate verdict — can you submit my track record and get back the signed grading receipt for REAL_EDGE certification?”

Endpoint
POSThttps://stillosdigitalholdings.com/bazaar-v2/grade-strategyWhen to prefer
Choose this endpoint when you need a third-party, cryptographically signed, economically bonded verdict on a trading strategy's track record — particularly when the verdict must be fee/slippage-adjusted, out-of-sample validated, and publicly disputable on-chain. Prefer it over generic backtesting tools when auditability, non-repudiation, and fail-closed classification are required.
Side effects
- Insufficient historical data returns INSUFFICIENT_DATA verdict rather than an error
- Malformed or missing track record body results in 4xx validation error
- Payment not included or invalid USDC amount returns 402 Payment Required
- On-chain bond verification unavailable may delay signed receipt
- Disputed verdict initiates slash process at /notary/dispute rather than returning a new verdict
