# Base Account API \[DEPRECATED]

The Base Account API powers [Patch wallets](https://app.patchwallet.com) and controls the [EIP-4337 account abstraction](https://eips.ethereum.org/EIPS/eip-4337) smart contract wallets called, Base Accounts.

Base Accounts are a simple smart contract wallet with the same address on all EVM chains and connected to a user's email, social account, phone, or an app provider. They are centered around the concept of a `user_id` which is a combination of a `provider` and `username`. 

#### **user\_ids:**

* `twitter:elonmusk`
* `email:your@mom.com`
* `github:torvalds`
* `yourapp:userid123`

### Submit a Transaction

To send a transaction through a Base Account, see the [Base Tx endpoint on Postman](https://www.postman.com/paymagic/workspace/public-patch-wallet-api).
