01AGENT INPUT
Buy 0.25 BTC · slippage ≤ 25 bps
The caller exposes the exact venue, side, size, and risk threshold.
EXPLICITExact-order preflight for crypto bots
Know the depth and slippage before every order.
Send the venue, side, and size. Butterfly Delta checks the live book and returns a signed PASS, BLOCK, or UNKNOWN for one cent.
One machine question. Primary evidence. Signed expiry.

The first repeated-use module
Execution integrity before every order.
Butterfly Delta does not choose, authorize, or execute the action. It checks the bot's own thresholds against current primary venue observations and reports assumption state inside explicit coverage.

Threshold state returned
HOLDS, INVALIDATED, or UNKNOWN is returned with observed value, source digest, and expiry.
SIGNEDEvidence touches an explicit assumption.
Evidence contradicts an explicit assumption.
No match inside declared coverage. Never means safe.

One thing, deliberately
Butterfly Delta maintains assumption state.
The agent states what must remain true.
Action, target, explicit assumptions, stakes, and last checkpoint.
We map verified change to those assumptions.
Observation, inference, judgment, unknowns, contradictions, and falsifiers stay separate.
The agent receives a signed, expiring result.
The caller's policy decides whether to continue, reevaluate, resize, or stop.
The compounding asset
A corrected history of what invalidated what.
Each event, dependency, contradiction, correction, and later outcome strengthens the same graph. That history—not raw headlines—is the moat.
- 01Canonical change
Deduplicate a real-world event and preserve its source lineage.
- 02Dependency edge
Map the event to assumptions used by agents across machine actions.
- 03Correction history
Never erase revisions; record what changed and why.
- 04Calibration
Measure whether later evidence confirmed, weakened, or falsified the mapping.
