E2 PRIMITIVES

Four building blocks developers can trust.

The API connects discovery, execution context and risk controls through a consistent definition layer.

Canonical market identity

Resolve tokenized instruments and venues by exact chain address, never by ticker inference.

Reference integrity

Read the validated external value plus source, timestamp and failure state used by E2.

Executable liquidity

Separate nominal market activity from direct same-block quote evidence at named impact bands.

Source completeness

Know when a value is current, partial, unavailable or blocked before building on top of it.
