`wallet_prepareCalls`

Prepares a call bundle.

It returns a digest of the call bundle to sign over, as well as the parameters required to fulfil a wallet_sendPreparedCalls request (context).

Request

type Request = {
  method: 'wallet_prepareCalls',
  params: [{
    /** Calls to prepare. */
    calls: {
      /** Recipient. */
      to: `0x${string}`;
      /** Calldata. */
      data?: `0x${string}`;
      /** Value to transfer. */
      value?: `0x${string}`;
    }[];
    /** 
     * Chain ID to send the calls to.
     * If not provided, the current chain will be used.
     */
    chainId?: `0x${string}`;
    /** 
     * Address of the account to send the calls from.
     * If not provided, the Account will be filled by the Wallet.
     */
    from?: `0x${string}`;
    /** Capabilities. */
    capabilities?: {
      permissions?: {
        /** ID of the permission to use. */
        id: `0x${string}`;
      };
    };
  }]
}

Response

type Response = {
  /** Chain ID the calls were prepared for. */
  chainId: `0x${string}`;
  /** 
   * Data to be forwarded to `wallet_sendPreparedCalls`.
   * For Porto, this will include the signed quote. 
   */
  context: { quote: unknown };
  /** Digest to sign over. */
  digest: `0x${string}`;
}

Example

import { Porto } from 'porto'
 
const { provider } = Porto.create()
 
const response = await provider.request({ 
  method: 'wallet_prepareCalls', 
  params: [{ 
    calls: [{ 
      to: '0xcafebabecafebabecafebabecafebabecafebabe', 
      value: '0x12345678',
