## Type Aliases

### SlotType

> **SlotType** = `bigint` & `object`

Defined in: [src/primitives/Slot/SlotType.ts:13](https://github.com/evmts/voltaire/blob/bd6ec34405c15ad8cd51d11579d495dc53813482/src/primitives/Slot/SlotType.ts#L13)

Slot type

Represents a consensus layer slot number (12 seconds per slot).
Slots are the fundamental unit of time in Ethereum's proof-of-stake consensus.
