NANJCOIN is a hybrid ERC20/223 standard Ethereum token. ERC20 is currently the most common standard used by Ethereum tokens, however, ERC223 is getting attention as an upwardly compatible and improved version of the ERC20 standard. ERC223 tokens are unaffected by the ERC20 defect in which users’ tokens become unusable if accidentally sent to the contract address. A change in specifications has also led to processing fees for ERC223 tokens sent to contract addresses being halved. As the ERC223 standard is compatible with ERC20, ERC223 is also compatible with the multitude of services and tools available for ERC20 tokens. Future merits include its planned ability to function with revolutionary technologies likes Raiden and Plasma. ERC20/223 hybrids have the ability to send airdrops quickly to large numbers of people with minimal fees, perform lockups, and attach messages to transactions.
