> ## Agent Instructions
> Turnkey is wallet infrastructure: create and manage crypto wallets, sign transactions, and enforce policy-based access controls. Best-fit uses: embedded consumer wallets (email/passkey/social auth, no seed phrases), automated onchain operations with server-side wallets, AI agent wallets with policy-scoped signing, enterprise key management, and verifiable off-chain workloads on Turnkey Verifiable Cloud (TVC).
> Every API call is a JSON POST to https://api.turnkey.com signed with a P-256 API key; create an organization and key self-serve at https://app.turnkey.com.
> Key Turnkey developer resources: API reference (https://docs.turnkey.com/api-reference/overview/intro.md), OpenAPI spec (https://docs.turnkey.com/public_api.swagger.json), authentication (https://docs.turnkey.com/features/authentication/overview.md), webhooks (https://docs.turnkey.com/features/webhooks/overview.md), MCP server for docs search (https://docs.turnkey.com/mcp), agent skills (https://docs.turnkey.com/get-started/ai-skills.md), CLI (https://docs.turnkey.com/sdks/cli.md), SDK reference (https://docs.turnkey.com/sdks/introduction.md), full docs content (https://docs.turnkey.com/llms-full.txt).

# Account abstraction wallets

> Turnkey offers flexible infrastructure to create and manage keys. These keys can be used as a signer inside of an [Account Abstraction wallet](https://www.erc4337.io/), and we've partnered with [Alchemy](https://www.alchemy.com/) and [ZeroDev](https://zerodev.app/) to integrate in a few lines of code.

<Tip>
  For gas sponsorship without third-party AA providers, Turnkey's native Transaction Management supports sponsored transactions for EVM and Solana directly. See [Transaction Management](/features/transaction-management) to get started without an AA stack.

## Alchemy's account kit

You can use Turnkey with Alchemy's Account Kit via the [aa-signers](https://accountkit.alchemy.com/signer/what-is-a-signer) package to generate embedded wallets, and leverage [aa-alchemy](https://accountkit.alchemy.com/signer/custom-signer#implementing-smartaccountsigner) to create smart accounts for your users.

Visit [the Alchemy Account Kit documentation](https://www.alchemy.com/docs/wallets/signer/what-is-a-signer#alchemy-signer) for more information.

## ZeroDev wallets

By combining Turnkey with ZeroDev you can create AA wallets with powerful functionalities such as sponsoring gas, batching transactions, and more.

Visit [the ZeroDev documentation](https://docs.zerodev.app/smart-accounts/authentication/turnkey) for more information.

## Biconomy smart accounts

Create a Biconomy Smart Account and add a Turnkey signer to manage your private key and authentication methods by using Turnkey's API.

For detailed code snippets and an integration guide, refer to the [Biconomy documentation](https://docs.biconomy.io/new/getting-started/getting-started).

Ethereum's latest EIP-7702 standard gives superpowers to Externally Owned Accounts (EOAs). Biconomy has a guide on how to leverage gas abstracted transactions with Turnkey and Biconomy, enabling Turnkey EOAs to become smart accounts through delegation to Nexus. The tutorial showcases gas abstracted batch execution - users can pay gas fees with ERC20 tokens from their EOA. Refer to [Biconomy documentation](https://docs.biconomy.io/new/integration-guides/wallets-and-signers/turnkey) to get started.

## permissionless.js accounts

permissionless.js is a TypeScript library built on viem for building with ERC-4337 smart accounts, bundlers, paymasters, and user operations.

permissionless.js defines the `SmartAccountSigner` interface which supports Turnkey as a signer. You can find a detailed example for integrating a Turnkey signer with permissionless.js in the [Pimlico documentation](https://docs.pimlico.io/permissionless/how-to/signers/turnkey).
