metamask 切换到EIP2559还需要手动设置 BaseFeePerGas

This runtime introduces many changes to our Ethereum layer, specially around the EIP 1559. Here are the important parts:

EVM 0.33.1 - London support

EIP-3198: BASEFEE opcode
EIP-3529: Reduction in refunds
EIP-3541: Reject new contracts starting with the 0xEF byte

Ethereum 0.11.1

EIP-2718: Typed transactions
EIP-2930: Optional access lists
EIP-1559: Fee market change

Ethereum API - Changes

• new rpc eth_feeHistory: Returns transaction fee data for up to 1,024 blocks.
• new rpc eth_maxPriorityFeePerGas: Returns a fee per gas that is an estimate of how much you can pay as a priority fee, or "tip", to get a transaction included in the current block.
• new property block.baseFeePerGas: baseFeePerGas used for the given block
• new property transactionReceipt.effectiveGasPrice: gas price being used for the transaction
• new property transaction.accessList: is an array of type [[{20 bytes}, [{32 bytes}...]]...], storing the contract address and the storage keys. Ex:

[
  [
    "0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae",
    [
     "0x0000000000000000000000000000000000000000000000000000000000000003",
     "0x0000000000000000000000000000000000000000000000000000000000000007"
    ]
  ], [
    "0xbb9bc244d798123fde783fcc1c72d3bb8c189413",
    []
  ]
]

• new property transaction.maxFeePerGas: how much BaseFee the transaction is allowed to pay.
• new property transaction.maxPriorityFeePerGas: Correspond to the "tip" to the miner. (Note: It is currently included in the normal fees, being 100% to validators)
• new property transaction.type: The current type of transaction 0 (Legacy), 1 (EIP-2930), 2 (EIP-1559)
  The base fee used in block is currently constant (450Gwei on SherpaX). The call the eth_gasPrice will return that value.
