Hello everyone, Can anyone tell me, how to identify that a transaction is cancelled or dropped, in the ethereum blockchain?
Thanks in advance
When you submit the transaction to the client you will receive a transaction hash back. You can look on the bockchain to see if that transaction has been incorporated or not. Even if it has not been incorporated yet, it's possible that the transaction is still outstanding and may be incorporated in the future (the transaction could be delayed because you set the gas price to a low value). If you want to 'cancel' the transaction to make sure it never goes through you must issue a new transaction (with the same nonce) which does get executed. Once the new transaction has been incorporated then the old transaction is no longer valid (because the nonce is wrong).
is there a tutorial on how to airdrop an erc20 token?

In solidity, A 'pure' function can neither modify the contract's data nor read it. Can you give example of a function that might need to be 'pure' ?
