Function createBatchSession

createBatchSession

Creates a session manager that handles multiple sessions at once for a given user's smart account. Useful for handling multiple granted sessions at once.

Example

import { createClient } from "viem"
import { createSmartAccountClient } from "@biconomy/account"
import { createWalletClient, http } from "viem";
import { polygonAmoy } from "viem/chains";
import { SessionFileStorage } from "@biconomy/session-file-storage";

const signer = createWalletClient({
  account,
  chain: polygonAmoy,
  transport: http(),
});

const smartAccount = await createSmartAccountClient({ signer, bundlerUrl, paymasterUrl }); // Retrieve bundler/paymaster url from dashboard
const smartAccountAddress = await smartAccount.getAccountAddress();
const nftAddress = "0x1758f42Af7026fBbB559Dc60EcE0De3ef81f665e"
const sessionStorage = new SessionFileStorage(smartAccountAddress); 
const sessionKeyAddress = (await sessionStorage.addSigner(undefined, polygonAmoy)).getAddress();

 const leaves: CreateSessionDataParams[] = [
   createERC20SessionDatum({
     interval: {
       validUntil: 0,
       validAfter: 0
     },
     sessionKeyAddress,
     sessionKeyData: encodeAbiParameters(
       [
         { type: "address" },
         { type: "address" },
         { type: "address" },
         { type: "uint256" }
       ],
       [sessionKeyAddress, token, recipient, amount]
     )
   }),
   createABISessionDatum({
     interval: {
       validUntil: 0,
       validAfter: 0
     },
     sessionKeyAddress,
     contractAddress: nftAddress,
     functionSelector: "safeMint(address)",
     rules: [
       {
         offset: 0,
         condition: 0,
         referenceValue: smartAccountAddress
       }
     ],
     valueLimit: 0n
   })
 ]

 const { wait, sessionID } = await createBatchSession(
   smartAccount,
   sessionStorageClient: sessionStorage,
   leaves,
   {
     paymasterServiceData: { mode: PaymasterMode.SPONSORED },
   }
 )

 const {
   receipt: { transactionHash },
   success
 } = await wait();

 console.log({ sessionID, success }); // Use the sessionID later to retrieve the sessionKey from the storage client
