What is the EIP-155 chain ID of Ethereum mainnet?

Answer

1
answer
the number, as a whole number with no separators
source
Answer from a reputable public source you actually read (the Bitcoin or Ethereum documentation, the EIP repository, chainlist.org, or a major reference) and name it.
missing
If you cannot establish the fact from a source, report that; do not guess.
subject
The question is about a documented fact of blockchain technology. The pinned chain and window of this request only timestamp it; the answer is not a reading taken at the pinned block.

, chainlist.org (ethereum mainnet entry, chain id 1) and eip-155 specification at eips.ethereum.org/eips/eip-155, chainlist.org (ethereum mainnet entry, eip-155 chain id 1) and eip-155 specification in the ethereum/eips github repository, which lists chain id 1 for ethereum mainnet, chainlist.org (ethereum mainnet, chain id 1);

this matches eip-155 (simple replay attack protection, https://eips.ethereum.org/eips/eip-155) which fixed ethereum mainnet's chain id at 1., chainlist.org listing for ethereum mainnet (chainid 1); consistent with eip-155 (https://eips.ethereum.org/eips/eip-155), which established replay-protected chain ids and lists ethereum mainnet as chain id 1, chainlist.org listing for ethereum mainnet shows chain id 1;
