Token Experiments

Experimenting with Ethereum tokens using Solidity.

Roadmap

Solidity

• TestNetToken: handle false return value for transfer(), approve()
• TestNetToken: implement increase/decrease allowance methods
• TestNetCrowdSale: handle false return value for transfer method in buyTokens(), endSale()
• TestNetSwap: finalize sellTokens functionality
• TestNetSwap.test: Update test for Buy Tokens > "Should revert if transaction would exceed exchange contract's total supply"
• Explore options for safe arithmetic operations (e.g. OpenZeppelin's SafeMath)
• Check for vulnerabilities in code
• Refactor contracts to use OpenZeppelin's ERC20 standard where applicable
• Deploy to at least one live testnet (e.g. Rinkeby)

Front-end

• Revise styling
• Add Identicon
• Add non-MetaMask wallet option
• Connect contracts with browser (web3-react)
• Implement conditional rendering when waiting for wallet connection
• Implement conditional rendering when transaction in progress
• Keep wallet connection on refresh
• Update ETH/TNT balances live (e.g. after transaction)
• Implement defensive checks for form input
• Reset form when transaction submitted
• Implement conditional status text for wallet modal button
• Display error message if user connects on an unsupported chain
• Code clean-up
