Configuring erdpy

erdpy can be configured using the erdpy config command.

In order to view the current configuration, one can issue the command erdpy config dump. Output example:

{
    "proxy": "https://gateway.elrond.com",
    "txVersion": "1",
    "dependencies.llvm.tag": "v...",
    "dependencies.vmtools.tag": "v...",
    "chainID": "...",
    "dependencies.rust.tag": ""
}

One can alter the current configuration using the command erdpy config set. For example, in order to set the proxy URL or the chain ID, one would do the following:

$ erdpy config set chainID 1...
$ erdpy config set proxy https://gateway.elrond.com
note

For mainnet use proxy: https://gateway.elrond.com and chainID: 1.

For devnet use proxy: https://devnet-gateway.elrond.com and chainID: D.

For testnet use proxy: https://testnet-api.elrond.com and chainID: T.

tip

erdpy's configuration is stored in the file ~/elrondsdk/erdpy.json.
