Multichain Account Abstraction

A Unified Wallet Experience

MANTRA’s wallet abstracts the need for users to manage multiple wallets or switch between blockchains. Through a single, unified interface, users can manage assets across various blockchains without needing to understand the underlying technology.

Multichain Account Abstraction empowers MANTRA users to sign and execute transactions across multiple blockchain networks with only 1 signature required. This innovation leverages Multi-Party Computation (MPC) and a decentralized network of node operators to generate joint signatures from any payload, enabling users to manage accounts on all chains effortlessly, and can utilize account abstraction features on any chain including passkeys, key rotation, etc.

How It Works

• Step 1: Add all your foreign blockchain accounts to a derivation path on MANTRA's portal and generate a unique address for all.

• Step 2: The transaction for the target blockchain is constructed by the client, which varies depending on the specific blockchain.

• Step 3: The MANTRA account or contract requests a signature through the MPC smart contract, and the distributed MPC service processes it.

• Step 4: Once the signature is received, the signed transaction is broadcasted to the target blockchain.

By maintaining a single decentralized user identity across multiple blockchains, this innovation enhances blockchain interoperability by granting every MANTRA wallet ownership and control over assets, accounts, and data across various chains, allowing a seamless experience for Web3 applications. In addition, Multichain Account Abstraction also allows programmatic encryption and decryption of data based on asset ownership, unlocking privacy-centric applications.
