Register ABI

When calling contracts, if using standard ERC20 methods, you can call directly without registration. Calling methods outside of standard contracts requires registering the ABI content first: exchange.IO("abi", tokenAddress, abiContent).

To obtain the contract's ABI content, you can use the following URL and extract only the result field.
