fetchCurrentSlot

function fetchCurrentSlot(
   graphqlEndpoint?: string, 
   slotType?: "global" | "epoch", 
headers?: HeadersInit): Promise<number>;

Defined in: lib/mina/v1/fetch.ts:584

Fetches the current slot number of the Mina network.

By default, returns the global slot since genesis (the cumulative count of all slots since the network launched). This matches fetchLastBlock().globalSlotSinceGenesis.

Alternatively, you can fetch the slot within the current epoch by passing slotType: 'epoch'. The epoch slot resets to 0 at each epoch boundary (approximately every 14 days) and ranges from 0 to ~7,139.

Parameters

graphqlEndpoint?

string = networkConfig.minaEndpoint

GraphQL endpoint to fetch from

slotType?

"global" | "epoch"

Type of slot to fetch: 'global' (default) for slot since genesis, or 'epoch' for slot within current epoch

headers?

HeadersInit

Optional headers to pass to the fetch request

Returns

Promise<number>

The slot number (either global or epoch-relative based on slotType)

Example

// Fetch global slot (default)
const globalSlot = await fetchCurrentSlot('https://api.minascan.io/node/devnet/v1/graphql');

// Fetch epoch-relative slot
const epochSlot = await fetchCurrentSlot(
  'https://api.minascan.io/node/devnet/v1/graphql',
  'epoch'
);
