Methods

getLatestVaas

getLatestVaas(priceIds: string[]): Promise<string[]>
Fetch the latest price update data for the given price IDs.

Uses Hermes v2 (/v2/updates/price/latest). The v1 endpoint (/api/latest_vaas) is deprecated; it returned the same payload this reads out of binary.data.

Hermes returns one accumulator message covering every requested feed, not one per feed, so the result is normally a single element regardless of priceIds.length.
Parameters
- priceIds: string[]
  Array of hex-encoded price IDs.
Returns Promise<string[]>
Array of base64-encoded update messages.

getPriceFeedsUpdateData

getPriceFeedsUpdateData(
priceIds: string[],
): Promise<Uint8Array<ArrayBufferLike>[]>
Fetch price feed update data.
Parameters
- priceIds: string[]
  Array of hex-encoded price IDs.
Returns Promise<Uint8Array<ArrayBufferLike>[]>
Array of buffers containing the price update data.
