Register ABI

Calling a contract that is a standard ERC20 method does not require registration and it can be called directly. Calling methods other than the standard contract requires registering the ABI content: exchange.IO("abi", tokenAddress, abiContent). To get the ABI content of a contract, you can use the following URL to get it, taking the result field only.
