When interacting on-chain, Gas has always been a barrier for new users. Different chains have different Gas tokens, and users often need to prepare a bunch of native tokens like ETH, ARB, OP to perform operations, resulting in a poor experience. In the design of Metalayer and Bridge Preview, Caldera has incorporated Gas abstraction functionality: users do not need to hold the Gas of the target chain, as the system will automatically handle it in the background.
This optimization in experience is particularly critical for the entry of a large number of users. Imagine a user who just wants to transfer stablecoins from Base to zkSync; if they also need to buy the Gas of the target chain, they might give up on the spot. However, Caldera's Gas abstraction completely eliminates this problem; users only need a single signature to complete cross-chain and payment.
Furthermore, Gas abstraction also means that applications can 'subsidize' the user experience. For example, a gaming chain can completely help players bear the Gas in the background, allowing users to have a frictionless interaction experience. This not only lowers the barrier but also opens up more possibilities for application design on-chain.
It can be said that Gas abstraction is an important breakthrough for Caldera in being 'user-centric', allowing complex on-chain logic to retreat behind the scenes and presenting the simplest and most intuitive experience to users.
