zone.getEncryptionKey

Gets the active sequencer encryption key and its zero-based index from a zone portal. This action uses a parent Tempo chain client.

Usage

import { client } from './viem.config'
 
const { keyIndex, publicKey } = await client.zone.getEncryptionKey({
  zoneId: 7,
})
 
console.log('Key index:', keyIndex)
console.log('Public key:', publicKey)

import { Account, createClient } from 'viem/tempo'
 
export const client = createClient({
  account: Account.fromSecp256k1('0x...'),
})

The key count and public key are read in one deployless multicall snapshot, keeping the key paired with its index during rotation.

Return Type

type ReturnType = {
  keyIndex: bigint
  publicKey: {
    // SEC1 compressed public key prefix.
    prefix: 2 | 3
    x: Hex
  }
}

Parameters

• Type: number

Zone ID whose portal contains the encryption key.

portalAddress (optional)

• Type: Address
• Default: Resolved from the client chain and zoneId.
