sendCalls

Send EIP-5792 calls to a wallet. This function works with all Thirdweb wallets (in-app and smart) and certain injected wallets that already support EIP-5792. Transactions will be bundled and sponsored when those capabilities are supported, otherwise they will be sent as individual transactions.

Example

import { createThirdwebClient } from "thirdweb";
import { sendCalls } from "thirdweb/wallets/eip5792";
 
const client = createThirdwebClient({ clientId: ... });
const wallet = createWallet("com.coinbase.wallet");
 
const sendTx1 = approve({
     contract: USDT_CONTRACT,
     amount: 100,
     spender: "0x33d9B8BEfE81027E2C859EDc84F5636cbb202Ed6",
   });
const sendTx2 = approve({
     contract: USDT_CONTRACT,
     amount: 100,
     spender: "0x2a4f24F935Eb178e3e7BA9B53A5Ee6d8407C0709",
   });
const bundleId = await sendCalls({
  wallet,
  client,
  calls: [sendTx1, sendTx2],
});

Sponsor transactions with a paymaster:

const bundleId = await sendCalls({
  wallet,
  client,
  calls: [send1, send2],
  capabilities: {
    paymasterService: {
      url: `https://${CHAIN.id}.bundler.thirdweb.com/${client.clientId}`
    }
  }
});
@note We recommend proxying any paymaster calls via an API route you setup and control.

Parameters

Returns

The ID of the bundle of the calls.
