Reading the data in a contract using Json-rpc

Question

With access to the contract abi, how can the data from a contract be read? You can get the byte code with eth_getCode but I don't understand how that can be converted to a readable form

Answer 1

I have found two methods for doing this:

• The data in a contract can be iterated through using eth_getstorageat at 0x0, 0x1 etc. You can use the abi to find which variables are stored at each index.

• Public variables are automatically assigned a getter function. This can be called with eth_call to return the value stored in that variable.
