Xcall-Dapp-sample-testing VS wormhole

xCall is not a bridge aggregator (i.e., LiFi, Socket) nor is it an interoperability protocol (i.e., BTP, IBC, Wormhole. xCall aggregates the features of all interoperability protocols through a single interface that standardizes cross chain messaging across the different protocols. Through such standardization, xCall is able to simplify cross chain dApp development for developers and to enable developers to leverage the unique strengths of the underlying interoperability protocols.

Security and Decentralization: Wormhole has nineteen guardians comprised of the leading PoS validators who jointly attest to messages. They all hold equal weight in consensus and governance. Of the 19 guardians, Wormhole requires over two-thirds to reach consensus and pass verification - thus, we assume that at least one-third of our guardian set is honest. Wormhole also has a comprehensive security plan consisting of all development in the open, one of the largest bug bounty programs ($10 million and counting), several quality audits 4 of its full codebase (one by Trail of Bits underway).

19:55 UTC — The bug was conclusively verified by internal peer review and multiple third-party auditing companies. The fix was committed to a temporary private fork of the Wormhole repository (it is now published to the public repository). The team circulated a contract upgrade governance proposal for Guardians to vote on. To expedite the process, simulations and testing of the fix were conducted in parallel. Since the network was down, the votes could not be immediately submitted. Therefore, a workaround was tested that would allow Guardians to submit governance votes without enabling token transfers.
