Build dApps with MetaMask Smart Accounts Kit — ERC-4337 smart accounts, delegations, and Advanced Permissions (ERC-7715)
Install
npx vskill@latest install internet-court/internet-court-skill/smart-accounts-kitSKILL.md
MetaMask Smart Accounts Kit
When to use
- You want to create ERC-4337 smart accounts (Hybrid, MultiSig, or Stateless7702)
- You want to send user operations or batch transactions via bundlers
- You want to configure signers (EOA, passkey/WebAuthn, multisig, wallet client)
- You want to implement gas abstraction with paymasters
- You want to create, sign, or redeem delegations (ERC-7710)
- You want to request Advanced Permissions via MetaMask extension (ERC-7715)
- You want to build automated backend services (DCA bots, keeper services) using delegations
- You want to implement session accounts for AI agents or automated trading
- You want to set up parallel user operations with nonce keys
Installation
Which smart account type to use
| Name | Usage | |
|---|---|---|
| Hybrid | A flexible account with EOA, wallet client, and passkey (WebAuthn) signers. The most flexible option for standard dApp users. | |
| MultiSig | Requires multiple signers to meet a threshold before transactions execute. Best for treasury, DAO, or shared custody use cases. | |
| Stateless7702 | Upgrades an existing EOA to a smart account using EIP-7702 while keeping the same address. Best for users with existing embedded EOAs. |
If the user hasn't specified which implementation they need, present the options.
Delegations vs Advanced Permissions
| Name | Usage | |
|---|---|---|
| Delegations (ERC-7710) | You create, sign, and manage delegations programmatically. The delegator is a smart account you control. You handle the full lifecycle: creation, signing, storage, and redemption. | |
| Advanced Permissions (ERC-7715) | You request permissions from a MetaMask user through a human-readable UI in the extension. MetaMask creates and enforces the delegations internally. The user can review and adjust parameters before approving. |
Advanced Permissions use delegations under the hood — ERC-7715 creates ERC-7710 delegations internally. If the user hasn't specified which to use, present the options.

Important notes
- Always use caveats — never create unrestricted delegations.
- Deploy the delegator first — the account must be deployed before redeeming delegations.
- Function call scope defaults to no native token — use
valueLteto allow it. - Caveats are cumulative in delegation chains — restrictions stack.
- ERC-7715 requires MetaMask Flask 13.5.0+ or MetaMask stable 13.23.0+, and the user must have a smart account.
- Always check that the project builds successfully after making changes.
- Smart Accounts Kit version: 1.6.0 | Delegation Framework: 1.3.0
