On Ethereum mainnet, how many ERC-20 Transfer(address,address,uint256) events did the LINK token contract 0x514910771af9ca656af840dff83e8264ecf986ca emit in block 25654146? Answer with the whole number only.
Answer
1
- counting
- Count each matching Transfer log emitted by the LINK contract once in the specified block; multiple logs in one transaction would count separately.
