Simplify your smart contract development

Stop writing custom delegation code in your contract, and let our flexible and general-purpose framework do the heavy lifting, so you can focus on the logic at the heart of your application. Up to a 95% reduction in smart contract code.

A toolkit to prepare for account native delegations

The Delegation Framework is open source and customizable. Implement it directly in your dapp or customize it further to suit the specific permissions and capabilities for your application.

Flexible account creation and user auth methods

Flexible account creation options, compatible with custom and burner EOA signers, 3rd party EOA signers, multisigs and passkeys. Supports a variety of onboarding and authentication flows such as QR code scans, invite links and email.

Flexible account recovery paths for your users 

The Delegation Framework is extensible and supports custom account recovery options. Recover your account by delegating to a friend or to a dapp. 

Innovative gas fee handling

A toolkit to help you build for an ERC-4337 compliant account. Works with any 3rd party bundler & paymaster. Delegation offers the added capability of gas deferral and gas-free, instant asset and account creation. 

Compatible with a wide variety of dapp platforms

Available in both Wagmi connector and custom Viem client libraries to make integration with MetaMask Delegator Accounts easy whether you are building a React project or in any JavaScript or Node.js environment. 

Supports all EVM Chains

MetaMask Delegation Toolkit can support any EVM chain, as long as there is a bundler to support userOps on that chain.

If you are in Brussels this week, did you get a chance to experience a game built with delegator contracts yet?
