[dependabot]

Bumps @nomiclabs/hardhat-etherscan from 2.0.1 to 3.0.3.

Release notes

Sourced from @​nomiclabs/hardhat-etherscan's releases.

@​nomiclabs/hardhat-etherscan v3.0.3

This is a small patch release fixing an error introduced in v3.0.2

Changelog

• Added Content-Type header to hardhat-etherscan's request for verifying contracts, in order to fix #2437.

@​nomiclabs/hardhat-etherscan v3.0.1

This release adds support for the Moonbeam network.

hardhat-etherscan v3.0.0

This new major version includes one of our most requested features: the possibility to specify multiple API keys for the hardhat-etherscan plugin (#1448).

You can learn more here, but the bottom line is that you can now do this in your config:

etherscan: {
  apiKey: {
      mainnet: etherscanApiKey,
      rinkeby: etherscanApiKey,
      optimisticKovan: optimismEtherscanApiKey,
      polygonMumbai: polygonscanApiKey,
      arbitrumTestnet: arbiscanApiKey,
  }
}

Importantly, the name of these keys don't necessarily match the name of the network in your config. See the docs to learn which names need to be used for each chain.

hardhat-etherscan v2.1.8

This release adds support for verifying contracts in the Avalanche Mainnet and Fuji chains, and in the Moonriver chain.

Thanks to @​marcelomorgado and @​x0s0l for their contributions!

hardhat-etherscan v2.1.6

This release adds support for the Arbitrum Testnet and the FTM Testnet. Thanks to @​kr1p70n1c and @​polarf0x0 for their contributions!

hardhat-etherscan v2.1.6

This release adds support for verifying contracts in Arbiscan, the block explorer for Arbitrum.
