# Account Abstraction (ERC-4337)

BlockPI can foresee the potentials of widespread adoption of Account Abstraction (AA) for lowering down the barrier of the blockchain use case and thus introducing web2 user experience to web3 industry.

To embrace the possibility of forming an AA market worthy of billions, BlockPI is dedicating resources to integrating AA into its infrastructure service. By building on the integration of AA, we aim to provide AA users with a more convenient and efficient way to interact with their contract wallet accounts on the blockchain, while also positioning BlockPI as a leader in the industry.

BlockPI will successively provide Bundler service, Paymaster service, signature aggregator service, etc. Please use the following instructions to use launched services.
