Phalcon Fork is designed to simulate transactions in a private testnet (named Fork) with mirrored mainnet states. It can be used in multiple scenarios, including (but not limited to):

  • Perform the (security) testing with real mainnet states when upgrading a contract, eliminating the bugs before the upgrade.

  • Create a public testing mode for the contract, letting users test run the DApp.

  • Write the PoC of security incidents.

  • Perform an attack simulation of DeFi protocols to excise the security incident response procedure.

  • Learn smart contract development.

  • ... you name it.

  • Mirror mainnet states, facilitating rapid integration and debugging with other real DApps.
