More than 110K of Bitcoins were moved to self-custody wallets last month.

**#Web3 = trust issues**

Here's how the #BiconomySDK leverages #AccountAbstraction (EIP-4337) and Smart Contract Wallets to power Self-Custody…

Self-custody empowers your users with full control of their assets. Custodial wallets could expose users' private keys. Not with non-custodial wallets.

Hot wallets (such as EOAs) are user-friendly because they’re online, but there are risks. Cold wallets are offline and more secure, but the UX can be clunky still.

Self-Custody via Smart Accounts means:

*   Privacy — no tracking of data and txns
    
*   Security — no one sees your private keys
    
*   Ownership — complete ownership of assets
    
*   Accessibility — 24/7 access to your assets
    
*   Smart Contract Wallets — Web2-like functionality
    

### Why did we leverage #AccountAbstraction (EIP-4337) to develop the #BiconomySDK?

As you can see, there are lots of practical benefits to [#AccountAbstraction](https://twitter.com/hashtag/AccountAbstraction?src=hashtag_click) and Smart Contract Accounts + Wallets.

### We're creating ease of access, seamless UX, and enhanced security with the #BiconomySDK. Mass adoption of users, did you say?
