Setup fairyport

Initialize fairyport config:

fairyport init

init command create a default config config.yml in the default directory $HOME/.fairyport . The config looks like this:

FairyRingNode:
    grpcport: 9090
    ip: 127.0.0.1
    port: 26657
    protocol: rpc
DestinationNode:
    grpcport: 9090
    ip: 127.0.0.1
    port: 26657
    protocol: rpc
Mnemonic: '# mnemonic'

Detailed explanation on the config:

FairyRingNode

Option	Description
ip	The IP address that Fairy Ring Node will use.
port	The port that Fairy Ring Node will use for TendermintRPC
protocol	The protocol used for communication via the TendermintRPC
grpcport	The port that Fairy Ring Node will use for gRPC communication with other nodes.

DestinationNode

Option	Description
ip	The IP address that Destination Node will use.
port	The port that Destination Node will use for TendermintRPC
protocol	The protocol used for communication via the TendermintRPC
grpcport	The port that Destination Node will use for gRPC communication with other nodes.

Mnemonic

Option	Description
Mnemonic	The seed phrase used to generate the private key for the account responsible for making transactions to the Destination Chain

Update the node ip and ports for fairyport to connect to and Mnemonic to your mnemonic phase. Note that fairyport derives your address with path m/44'/118'/0'/0/0 by default.

The updated config should looks like this:

FairyRingNode:
  ip: "127.0.0.1"
  port: 26657
  protocol: "tcp"
  grpcport: 9090

DestinationNode:
  ip: "127.0.0.1"
