-NOTE: you should always set `evmVersion` to `berlin`, Metis doesn't support `shanghai` hardfork yet.

-non-EIP155 txs is disabled for now
-
-you should always use EIP155 to build and sign your transactions.
-
-We will enable non-eip155 txs in next hardfork.
-
-2. Native token and wrapped
-
-Metis is a native token but also an ERC20 compatible token on Layer 2.
-
-It is a built-in feature, so there is no need to create a wrapped Metis token, and the source code is [here](https://github.com/MetisProtocol/mvm/blob/develop/packages/contracts/contracts/MVM/MVM_Coinbase.sol).
-
-Sushiswap team deployed a wMetis, it's the same with WETH9, and the contract address is [0x75cb093E4D61d2A2e65D8e0BBb01DE8d89b53481](https://andromeda-explorer.metis.io/address/0x75cb093E4D61d2A2e65D8e0BBb01DE8d89b53481/contracts)
-
-ETH is an ERC20 token on Metis, its addresss is `0x420000000000000000000000000000000000000A`
-
-2. RPC methods
-
-It's the same with Ethereum.
-
-Check out [our documentation](https://docs.metis.io/dev/get-started/metis-connection-details) for rpc endpoints
-
-3. Gas fee
-
-It's the same with Ethereum.
-
-4. Block timestamp
-
-As said before. timestamp is not the same with current unix time, because Metis is an layer 2 chain, it depends on Ethereum layer 1 to get the timestamp.
-
-internally, Metis refreshes the timestamp once 1 minute for Andromeda. so you can see that many blocks have the same time on explorer or rpc.
-
-by the way, blocks are not generated at a constant time, a transaction will be confirmed immediately.
