Web3 Messaging Tools
xCall Service is a standardized interface that simplifies cross-chain development.
xCall Service empowers developers to broaden the reach of their dApps across multiple ecosystems from their preferred chains.
It delivers seamless cross-chain connectivity by enabling contract calls to destination chains from source chains through a single standard that works across protocols.
xCall Service is a lightweight contract that can extend across any protocol and will add support for new cross-chain messaging protocols as they emerge.
This approach increases versatility while strengthening security through multiple protocol verifications.
The opening part of a hands-on series: wiring a vote that originates on one chain and settles on another, written by an ICON validator.
The part most tutorials skip: how to test contracts whose behaviour depends on a message arriving from somewhere else.
Walks the circuits behind a Sudoku game built with ZK proofs, showing what the constraint system actually has to express.
