Coinfabrik was asked to audit the contracts for the CryptoCup ERC721 Token. Firstly, we will provide a summary of our discoveries and secondly, we will show the details of our findings.
Lately, lots of posts have been talking about how traders get rich from arbitrage opportunities in the crypto market. I have been trying to do arbitrage for months, but I could never obtain a profitable strategy. Therefore, I will tell you here the problems I found while attempting to do it. This might be helpful […]
The most important benefit that Bitcoin and Blockchain Technologies have brought to us is a low-entry barrier to deploy our own currency and financial ledger. This means that, now, we can easily implement the concepts of Free Banking.
In my last article, I’ve shown you how to make a Solidity ERC20 Token for the RSK Mainnet, how to import and use OpenZeppelin libraries and contracts, and how to use Truffle to deploy and interact with our contract.
Although we succeeded in our quest and accomplished our objectives using Truffle, eventually this suite might present failures when you are sending transactions, deploying or managing accounts. In our case, while following the previous article instructions, I’ve had problems managing newly created accounts in Truffle and sending transactions.
In the last article, we have seen how to build an RSK node in our computer, select the proper network for development, configure Truffle to connect and deploy our future contracts, add accounts to our node and obtain funds to use them to pay the gas.
You should have now your node in the selected network fully synced, and at least one account with funds configured in the truffle and RSK node config files for our deployments.
In this article, we’ll be discussing deployment and interaction of Smart-Contracts over the RSK network. Our contract will be an ERC20 Token, based on the OpenZeppelin libraries, and we will deploy it directly into the Mainnet.
These last years there has been growth in Smart Contracts development, predominantly in the Ethereum blockchain. Ethereum, being a different type of blockchain than Bitcoin, can execute concise lines of code inside its chain, a job that Bitcoin (specifically designed to send transactions easily) can’t do. Here is where RSK intervenes building a sidechain tied up to Bitcoin through a 2-Way Peg system, managed by the Federation Partners, that makes code execution possible. Instead of designing a new programming language for developing Smart-Contracts, they used Solidity, the same language that Ethereum uses. This has two benefits: not only programmers won’t have to learn a new skill but also contracts in the Ethereum network could be deployed in RSK without much effort, taking advantage of the vast market capitalization Bitcoin has.
