Upgrade your EOA to a Mimic 7702

Traditional EOAs are designed for manual interaction and typically require repeated approvals and signatures, making them a poor fit for automated workflows.

This guide shows how to upgrade an existing EOA into a Mimic 7702 smart account, enabling automation-friendly behavior without deploying a new smart account contract.

---

Can I deploy a smart account contract instead?

Yes, that's possible. However, there are some downsides to bear in mind:

• Deployment requires gas

• A new address must be managed

• Funds often need to be migrated

For many users, this upfront complexity is unnecessary.

What EIP-7702 enables

EIP-7702 allows an EOA to authorize a smart account implementation via a special transaction.

This means:

• The EOA keeps the same address

• No deployment step is required

• The account can behave like a smart account when needed

---

How Mimic uses EIP-7702

Mimic uses EIP-7702 to let EOAs opt into richer execution behavior only when required.

Once upgraded:

• The EOA can participate in automation flows

• Execution logic is delegated safely

• Repeated approvals are avoided

All execution complexity is handled by Mimic.

Upgrading your EOA

Mimic provides a small command-line tool that performs the upgrade in a single transaction.

At a high level:

1. Configure your RPC and private key

2. Specify the official Mimic Smart Account address

3. Run the upgrade command

From your command line, clone the repository:

git clone https://github.com/mimic-fi/mimic-7702-upgrade

Enter the cloned repository and install dependencies:

cd mimic-7702-upgrade && yarn

Create a .env file from the example:

cp .env.example .env

Fill in the following variables:

• RPC_URL – RPC endpoint for the target chain

• PRIVATE_KEY – EOA private key to be upgraded

• SMART_ACCOUNT_ADDRESS – Official Mimic EIP-7702 Smart Account implementation address

EIP-7702 authorization is powerful. Only authorize Smart Account addresses provided by official Mimic sources.

Upgrade your EOA

yarn upgrade-7702

This sends a zero-value self-transaction containing an EIP-7702 authorization that upgrades the EOA to a Mimic smart account.

Check status

yarn status

This prints basic wallet and network information and provides helpful explorer links for manual verification.

Rollback your EOA

yarn downgrade-7702

This sends a zero-value self-transaction containing an EIP-7702 authorization that rolls back your EOA to its original status.
