  Attaching a Tempo chain to your client grants your transaction actions with Tempo superpowers like batched calls and external fee payer capabilities.

  import { createClient, http } from "viem";
  import { privateKeyToAccount } from "viem/accounts";
  import { tempoTestnet } from "viem/chains";
  
  const client = createClient({
    account: privateKeyToAccount("0x…"),
    chain: tempoTestnet.extend({
      feeToken: "0x20c00000000000000000000000000000000000fa",
    }),
    transport: http(),
  });
  
  const receipt = client.sendTransactionSync({
    calls: [
      { data: "0x…", to: "0x…" },
      { data: "0x…", to: "0x…" },
      { data: "0x…", to: "0x…" },
    ],
    feePayer: privateKeyToAccount("0x…"),
  });

  You can also use Tempo Actions to call to enshrined protocol features like the Stablecoin Token Factory:

  import { createClient, http } from "viem";
  import { privateKeyToAccount } from "viem/accounts";
  import { tempoTestnet } from "viem/chains";
  import { tempoActions } from "viem/tempo";
  
  const client = createClient({
    account: privateKeyToAccount("0x…"),
    chain: tempoTestnet,
    transport: http(),
  }).extend(tempoActions());
  
  const { receipt, token } = await client.token.createSync({
    currency: "USD",
    name: "My Company USD",
    symbol: "CUSD",
  });
