FAQ

• Can this be used to cheat or hack Clash of Clans?

  No. The official server will detect manipulations and you will get an "out of sync" error.

• Can this be used to write a private server for Clash of Clans?

  Yes. Have fun implementing Clash of Clans's custom libsodium crypto!

• How can I contribute?

  • Update the offsets for new versions (agent/offsets.ts)
  • Add new packet IDs (agent/packet.ts)
  • Improve stability
