Has anybody a good solution to manage the (etherscan verification) API-keys depending on the chain ?

[SvenMeyer]

the API-key for verification on Etherscan , BSCscan , ... is still hard coded in my hardhat.config.ts
Ideally it would be set depending on the provided network ... and suggestions ?

  etherscan: {
    apiKey: "42WH....................FK43H92W5N" // process.env.ETHERSCAN_API_KEY,
  },

[SvenMeyer]

also something similar would also be great to set different mnemonic based on chain, ..

This is an issue with hardhat-etherscan itself. It's being tracked here:
