• GRPC_ENDPOINT: Default = '127.0.0.1:9090'
• MEMO: Default = 'Sent from Hanchon's faucet'
• FEE: Default = '20'
• GAS_LIMIT: Default = '200000'
• CHAIN_ID: Default = 'evmos_9000-1'
• DENOM: Default = 'aphoton'

Usage

from evmosgrpc.messages.msgsend import create_msg_send
from evmosgrpc.builder import TransactionBuilder
from evmosgrpc.transaction import Transaction

seed = 'garment seat help gallery ride divide truth smooth end chunk '\
       'ten cross badge want vehicle mirror dismiss remind crouch '\
       'base crouch palm leader dinner'
builder = TransactionBuilder(seed)
msg = create_msg_send(
    builder.address,
    "evmos1sgg7ny6mkk375ghdlx837hkm92dqxs450fxwwz",
    100,
)
res = builder.send_tx(Transaction().generate_tx(builder, msg))
# res =
# tx_response {
#   txhash: "F4DFCF8E0BAEBBE088DF0C8A4DA1EF70CD29983C5F7663A523A87F1CE479BFF5"
#   raw_log: "[]"
# }

# To read the response as a dict:
from google.protobuf.json_format import MessageToDict
res_obj = MessageToDict(res)

TODO

• Add tests.
• Add more messages.
• Add secp256k1 wallet support on evmoswallet.
