Helper library to query/post Indium transactions

• Initialize with the host+port of an Indium node which has RPC enabled:

indium = Indium.custom("http://your-rpcnode.url:8545", chain_id = 246)
indium = Indium.prod # which uses url = http://rpcnode.indium.network:8545 and chain_id = 246

• Generate a keypair (offline operation):

public_key, private_key = indium.create_keypair

• Check account balance of an address/public key:

indium.balance(pubkey)

• Transfer some coins to an address (need sender's private key and recipient's public key):

# Txn is signed locally so private keys are never transmitted
indium.transfer(nil, sender_privkey, receiver_pubkey, amount, hex_data, gas_limit = 21_000, gas_price = 3_141_592)

• For other methods (deploying/invoking contracts, creating a txn from scratch etc.), you can directly access the internal client obj with indium.client which is documented here:
