simd scripts

Boilerplate scripts for boostrapping simd nodes and relayer

Installing simd

Install the simd binary from the ibc-go repository.

git clone git@github.com:cosmos/ibc-go.git && cd ibc-go

make install

Installing Hermes

cargo install ibc-relayer-cli --bin hermes --locked

hermes version

Setup chains

Bootsrap two simd chains. The following will clear any existing chain state under ./data and create a new environment. It bootstraps two single validator nodes for different simd chains test-1 and test-2.

The scripts create a couple of accounts, both for relayers and demo accounts.

make init

Restore keys using Hermes

Restore keys for relayer wallets rly-1 and rly-2.

make hermes-restore-keys

Setting up IBC transport and relaying.

Create a connection from test-1 to test-2. Note, this also creates ibc clients out of the box.

make hermes-setup-connection

Create an incentivized transfer channel.

make hermes-setup-channel

Start relaying.

make hermes-start

Ledger signing

1. Setup your ledger using LedgerLive and download the cosmos app.
2. Create a new cosmos account address. Note that ibc simapp uses the cosmos bech32 prefix.
3. Your device is now ready for testing using ibc simapp.

Where cosmos1kzjk9frgfgpguvdazesgpllwsggk8472xryjvr is your ledger account address.

Add your ledger key:

simd keys add ledgerKey --ledger --home ./data/test-1

Fund your ledger account from one of the demo accounts - wallet1:

simd tx bank send wallet1 cosmos1kzjk9frgfgpguvdazesgpllwsggk8472xryjvr 1000000stake --from wallet1 --chain-id test-1 --node tcp://localhost:16657 --home ./data/test-1 --keyring-backend test

Query balance of ledger account:

simd q bank balances cosmos1kzjk9frgfgpguvdazesgpllwsggk8472xryjvr --home ./data/test-1 --node tcp://localhost:16657

Regular bank send using ledger signing:

simd tx bank send cosmos1kzjk9frgfgpguvdazesgpllwsggk8472xryjvr cosmos17dtl0mjt3t77kpuhg2edqzjpszulwhgzuj9ljs 10stake --from ledgerKey --chain-id test-1 --ledger --node tcp://localhost:16657 --home ./data/test-1

IBC transfer using ledger signing:

simd tx ibc-transfer transfer transfer channel-0 cosmos17dtl0mjt3t77kpuhg2edqzjpszulwhgzuj9ljs 1000stake --from ledgerKey --chain-id test-1 --ledger --node tcp://localhost:16657 --home ./data/test-1
