At what block number did the London upgrade, which introduced EIP-1559, activate on Ethereum mainnet?
Answer
12,965,000
12965000 uint256
- answer
- the number, as a whole number with no separators
- source
- Answer from a reputable public source you actually read (ethereum.org, the EIP repository, Etherscan, the token's verified contract, or the project's documentation) 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 Ethereum mainnet and its on-chain history. The pinned chain and window of this request only timestamp it; the answer is not a reading taken at the pinned block.
