Backed with $3M, Soul Wallet aims to bring self-hosted crypto wallets to the next billion

At the center of the movement is the ERC-4337 standard introduced by the Ethereum Foundation, the non-profit research affiliate of Ethereum, the world's second-largest cryptocurrency that boasts a vibrant developer community.
