Prepare

The following process will spawn a local infra compose by:

• A lazychain node: Artela Rollkit
• A Stargaze node: Cosmos blockchain
• A Hyperlane Bridge compose by a Relayer node and 2 validators nodes for Lazychain and Stargaze with all the contracts deployed and configured by the setup

We use 2 dummy wallets that are set up in the environment. These wallets are set up locally, no funds on real blockchain.

export HYP_KEY="arctic eagle supply pair melody ripple rigid bench suspect symbol image play web tobacco vessel kitchen mammal hard stamp spoon entire frown detail cherry"
export VAL_KEY="icon hospital stick paddle turn suspect gentle since raven sign chair raise super tiger seat six allow april praise school chaos movie gold yard"

Clone the repository and run the infra via kurtosis

git clone https://github.com/Lazychain/lazy_poc && cd lazy_poc
kurtosis clean --all && kurtosis run --enclave test . "$(echo { \"DEV_MNEMONIC\": $HYP_KEY, \"VAL_MNEMONIC\": $VAL_KEY})"

All the process is detailed on notes

Checks

Once you get the response from the kurtosis it will display the nodes and ports to be used. You can do the following checks:

lazy:

• rpc: curl --silent localhost:26657/status | jq .result.node_info.network : "artroll_11820-1"
• json-rpc: curl --silent http://127.0.0.1:8545 -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"net_version","params":[],"id":67}' | jq .result : "11820"
• json-rpc: cast client -r http://127.0.0.1:8545 : <appd>//linux-amd64/go1.22.8
• grpc: grpcurl -plaintext 127.0.0.1:8090 list should response

stargaze:

• rpc: curl localhost:21657/status | jq . should response
• grpc: grpcurl -plaintext 127.0.0.1:8090 list should response
• rest: curl --silent http://localhost:1316/cosmos/base/tendermint/v1beta1/blocks/latest | jq .block.header.chain_id "testing"

Balance:

• balance: cast balance 0x468402289EbA56fC07aBf413aBF9f0a6Da4Ea15D : "100000000000000000000"
• balance: curl --location http://localhost:1316/cosmos/bank/v1beta1/balances/stars1cmxt3mt7vfcncs64ycsgjvep7xecv0grsr47p3 | jq .balances[0]

Wallets:

cd sdk
bun run src/index.ts wallet recover "$(echo $HYP_KEY)"

cd sdk
bun run src/index.ts wallet balance 0x468402289EbA56fC07aBf413aBF9f0a6Da4Ea15D

Test the hyperlane bridge

1- Deploy, init and send a receipt message from lazy chain to stargaze.

cd sdk
bun run src/index.ts test-dispatch-eth "lazy" "$(echo $HYP_KEY)"

http://localhost:8545
[SUCCESS] [test-dispatch] Receipt sent
[test-dispatch] ism addr[0x397925Dbfbc3c42f4b3eFa5E11e9B8e7c2B39CC7]

[NOTICE] [test-dispatch] smart contract receipt addr[0x911361aB56F5961BA45884be01Ec1986e836921C]

2 - Check the received receipt

Using the lazy receipt addr[0x911361aB56F5961BA45884be01Ec1986e836921C] run:

cd sdk
bun run src/index.ts test-dispatch-cosmos "0x911361aB56F5961BA45884be01Ec1986e836921C" "stargaze" "$(echo $HYP_KEY)"
