I'm trying to create token on etherum, wanted to know if is it possible to create separate token for external purpose and internal system usage purpose.
Just like steemit do it, STEEM is what people buy, but within the system they use SteemDollar and SteemPower
Can anyone help me out in this?
Here’s a technical walkthrough series for Ethernaut’s smart contract hacking puzzles. It’s been a good learning resource to dive deeper into the vulnerabilities of Solidity, i.e. a Turing complete language on the blockchain.
Thought I’d document my learning journey for public benefit here: https://hackernoon.com/ethernaut-lvl-1-walkthrough-how-to-abuse-the-fallback-function-118057b68b56
@sierra1bravo Hey Sierra, in general, you don't want to use "transfer" to move tokens around. Try using the approve+transferfrom combo, see why transfer opens you to security issues here: https://medium.com/coinmonks/ethernaut-lvl-15-naught-coin-walkthrough-how-to-abuse-erc20-tokens-and-bad-icos-6668b856a176. Transfer() was how a lot of ICOs got tokens permanently locked.
