In today’s technological world, one of the major problems limiting the widespread use of blockchain is its complicated user interface and daunting transition from Web2 to Web3. The complexity involves technical login procedures, numerous seed phrases, unfamiliar terminologies etc. which prevent potential users from tapping into the decentralised ecosystem.
The critical need for an improved user experience (UX) to drive mass adoption has led developers and marketers to tirelessly enhance the accessibility and usability of blockchain technologies. MetaMask Snaps represents a promising innovation in achieving seamless interaction with decentralized applications (dApps) and various blockchain technologies.
As one of the world’s leading EOA (Externally Owned Account) wallets, MetaMask has recognized the importance of account abstraction and UX enhancements in drawing the next wave of users to Web3. In response, MetaMask introduced Snaps, a revolutionary platform that empowers developers to build custom features on the existing MetaMask infrastructure.
