# Building Blocks

JasperVault derives from cutting-edge innovations in the EVM and DeFi ecoystem, implementing [**ERC-4337 Account Abstraction**](https://eips.ethereum.org/EIPS/eip-4337) while drawing inspiration from the [**Set Protocol V2**](https://docs.tokensets.com/protocol/litepaper)'s architectural design. The result is a modular and extensible contract system fit for secure DeFi Asset Management.

It is recommended to have at least a basic understanding of ERC-4337 in order to understand the other pages in the dev docs. To that end, the next page includes a brief overview of the specification's core concepts.
