Testing Packet Forwarding
Prerequisites
- Gaiad
(v6.*.*). The version can be checked with:
gaiad version --log_level error --long | head -n4
Testing procedure
Setup using Gaia manager
Note: The
gm.tomlfile that we're using here looks like this:
[global]
add_to_hermes = true
auto_maintain_config = true
extra_wallets = 2
gaiad_binary = "/Users/luca/go/bin/gaiad"
hdpath = ""
home_dir = "/Users/luca/.gm"
ports_start_at = 27000
validator_mnemonic = ""
wallet_mnemonic = ""
[global.hermes]
binary = "$HOME/.hermes/bin/hermes"
config = "$HOME/.hermes/config.toml"
log_level = "trace"
telemetry_enabled = true
telemetry_host = "127.0.0.1"
telemetry_port = 3001
[ibc-0]
ports_start_at = 27000
[ibc-1]
ports_start_at = 27010
[ibc-2]
ports_start_at = 27020
- Run the command
gm start - Run the commands:
gm hermes configandgm hermes keys

Obtain the addresses of the wallets on each chain:
hermes keys list --chain ibc-0SUCCESS - wallet2 (cosmos179ld56nmany7nqmsdjz684rx5t4r5gxspn6hgr) - wallet (cosmos1gz507egejvz3ukg3xwr3v04n3xcny7vcnkjw32) - wallet1 (cosmos14cgtalvczzm6xuaa086g5tx6sss6e85j55vqrd)hermes keys list --chain ibc-1SUCCESS - wallet2 (cosmos1pmzq62tewxla9z7gpntcnvszyrkygnk4mesauy) - wallet (cosmos1jwr34yvnkqkc0ddndnh9y8t94hlhn7rapfyags) - wallet1 (cosmos1at4nj238c3ltlj0wymwgfjmdjctlvstwj8xl2s)hermes keys list --chain ibc-2SUCCESS - wallet2 (cosmos1xpezl2vvwg9fhdmksvne6lygd7dwz4vf65v6ye) - wallet (cosmos1nsztzzhl553avufxhqa204908l4dndafqph4tw) - wallet1 (cosmos1csdnmydggcyvjd7z8l64z9lpdgmgyr4v7hw5r8) -
(Optional) Check the balance of the wallets before transferring tokens:
hermes keys balance --all --chain ibc-0SUCCESS Balances for key `wallet`: 100000000 samoleans 99992294 stakehermes keys balance --all --chain ibc-1SUCCESS Balances for key `wallet`: 100000000 samoleans 99983377 stakehermes keys balance --all --chain ibc-2SUCCESS Balances for key `wallet`: 100000000 samoleans 99990916 stake -
(Optional) Confirm the name of the channels used for the transfer:
hermes query channels --counterparty-chain ibc-1 --chain ibc-0SUCCESS [ PortChannelId { channel_id: ChannelId( "channel-0", ), port_id: PortId( "transfer", ), }, ]hermes query channels --counterparty-chain ibc-2 --chain ibc-1SUCCESS [ PortChannelId { channel_id: ChannelId( "channel-1", ), port_id: PortId( "transfer", ), }, ] -
In a separate terminal, start an instance of Hermes:
hermes start -
Transfer token using the special receiver:
hermes tx ft-transfer --denom samoleans --receiver 'cosmos1jwr34yvnkqkc0ddndnh9y8t94hlhn7rapfyags|transfer/channel-1:cosmos1nsztzzhl553avufxhqa204908l4dndafqph4tw' --timeout-seconds 120 --dst-chain ibc-1 --src-chain ibc-0 --src-port transfer --src-channel channel-0 --amount 2500SUCCESS [ IbcEventWithHeight { event: SendPacket( SendPacket { packet: Packet { sequence: Sequence( 2, ), source_port: PortId( "transfer", ), source_channel: ChannelId( "channel-0", ), destination_port: PortId( "transfer", ), destination_channel: ChannelId( "channel-0", ), data: [123, 34, 97, 109, 111, 117, 110, 116, 34, 58, 34, 50, 53, 48, 48, 34, 44, 34, 100, 101, 110, 111, 109, 34, 58, 34, 115, 97, 109, 111, 108, 101, 97, 110, 115, 34, 44, 34, 114, 101, 99, 101, 105, 118, 101, 114, 34, 58, 34, 99, 111, 115, 109, 111, 115, 49, 106, 119, 114, 51, 52, 121, 118, 110, 107, 113, 107, 99, 48, 100, 100, 110, 100, 110, 104, 57, 121, 56, 116, 57, 52, 104, 108, 104, 110, 55, 114, 97, 112, 102, 121, 97, 103, 115, 124, 116, 114, 97, 110, 115, 102, 101, 114, 47, 99, 104, 97, 110, 110, 101, 108, 45, 49, 58, 99, 111, 115, 109, 111, 115, 49, 110, 115, 122, 116, 122, 122, 104, 108, 53, 53, 51, 97, 118, 117, 102, 120, 104, 113, 97, 50, 48, 52, 57, 48, 56, 108, 52, 100, 110, 100, 97, 102, 113, 112, 104, 52, 116, 120, 34, 44, 34, 115, 101, 110, 100, 101, 114, 34, 58, 34, 99, 111, 115, 109, 111, 115, 49, 103, 122, 53, 48, 55, 101, 103, 101, 106, 118, 122, 51, 117, 107, 103, 51, 120, 119, 114, 51, 118, 48, 52, 110, 51, 120, 99, 110, 121, 55, 118, 99, 110, 107, 106, 119, 51, 50, 34, 125], timeout_height: Never, timeout_timestamp: Timestamp { time: Some( Time( 2022-11-10 16:05:13.409228, ), ), }, }, }, ), height: Height { revision: 0, height: 59, }, }, ] -
