I am trying to figure out how to airdrop tokens to all holders of a old tokens with a new token the exact number of tokens in their wallet?

Use the old token's address to get the balance of tx.origin in your smart contract and let them withdraw that amount of new tokens only.

And keep an address to bool mapping to keep track of the addresses which already claimed the airdrop.

Interesting, can I Dm you?

Okay

Google "solidity erc20 swap example". However, make sure to keep security measures like safemath etc.

Oh cool..thanks man..let me do that now.

Binance to binance

Yes

Ok

Please does he need safemath if he is using solidity 0.8?

If I am not wrong from 0.8.0 safemath is not needed

❤

uniswap use it

No, from 0.8 onwards safemath is "inbuilt".

thank you very much

available

But while using solidity 0.8.x will you love to use safemath and why? Just wondering.

Thanks.

😁😁
