Hello everyone,
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?

Hi, I am 100% new to smart contracts and am looking for a combined token and crowdsale contract that is secure. I copied some code from a site that is basically a tutorial but when I put it through Securify it gave me all kinds of errors. Is there anyplace I can find what I am looking for?

Hey everyone,
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

I have 4 actors and each perform similar functions like create asset, transfer asset, receive, reject
will it be a good design to have 4 contracts each for 1 actor
or i can have them as 2 contracts -> first contract between first actor and second actor(asset shape is different), second contract between second actor and the rest of actors in the chain(asset shape is different)

@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.

Try pasting your code into RemixIDE to get started with the least setup time: http://remix.ethereum.org/
