I have two ethereum private networks, each with a smart contract deployed. for example network.A and network.B

Now how can smart contract of network.A calls smart contract functions of network.B?

  • Short answer: smart contracts cannot call other smart contracts from different networks. You would need to rely on externally owned accounts to make calls and validate signatures and data. Mar 18, 2022 at 11:07
  • The usual solution is to implement some sort of bridge between the blockchains. See here for something similar between ERC20 tokens ethereum.stackexchange.com/questions/99110/….
