The calldata has been pre-authed, so you don't need any\n// special permissions to send this transaction\nlet anotherWallet = new ethers.Wallet('')\nconst tx = await anotherWallet.sendTransaction({\n to,\n data,\n value,\n gasLimit,\n})\n```\n\nUse `encodeExecuteOwnHooks` to encode a factory `executeOwnHooks` call.\n\n### Using via Cow SDK\n\nYou can also import `CowShedSdk` directly from the main SDK:\n\n```ts\nimport { ethers } from 'ethers'\nimport { CowShedSdk, ICoWShedCall, SupportedChainId } from '@cowprotocol/cow-sdk'\nimport { EthersV6Adapter } from '@cowprotocol/sdk-ethers-v6-adapter'\nimport { JsonRpcProvider, Wallet } from 'ethers'\n\n// Proper adapter initialization\nconst provider = new JsonRpcProvider('YOUR_RPC_URL')\nconst wallet = new Wallet('YOUR_PRIVATE_KEY', provider)\nconst adapter = new EthersV6Adapter({ provider, signer: wallet })\n\nconst cowShedSdk = new CowShedSdk(adapter) // adapter is optional - will use global adapter if not provided\n// ... rest of the usage remains the same\n```\n","readmeFilename":""}
