Not for production. Best used as example.

Also part of e2e test-suite.

How to start

1. Optimize contract

cargo run-script optimize

2. Store contract

babylond tx wasm store ./artifacts/storage_contract-aarch64.wasm --from=user --gas=auto --gas-prices=1ubbn --gas-adjustment=1.3 --chain-id="euphrates-0.5.0" -b=sync --yes --log_format=json --node=https://rpc-euphrates.devnet.babylonlabs.io

3. Get code id

curl -s -X GET "https://lcd-euphrates.devnet.babylonlabs.io/cosmwasm/wasm/v1/code" -H "accept: application/json" | jq -r '.'

codeId=$(curl -s -X GET "https://lcd-euphrates.devnet.babylonlabs.io/cosmwasm/wasm/v1/code" -H "accept: application/json" | jq -r '.code_infos[-1].code_id'); echo $codeId

4. Instantiate contract

babylond tx wasm instantiate $codeId '{}' --from=user --no-admin --label="cyferio_storage" --gas-prices=1ubbn --gas-adjustment=1.3 --chain-id="euphrates-0.5.0" -b=sync --yes --log_format=json --node=https://rpc-euphrates.devnet.babylonlabs.io

5. Get contract address

curl -s -X GET "https://lcd-euphrates.devnet.babylonlabs.io/cosmwasm/wasm/v1/code/$codeId/contracts" -H "accept: application/json" | jq -r '.'

address="$(curl -s -X GET "https://lcd-euphrates.devnet.babylonlabs.io/cosmwasm/wasm/v1/code/$codeId/contracts" -H "accept: application/json" | jq -r '.contracts[-1]')"; echo $address

6. Execute contract

data='hello world'
dataHex=$(echo -n $data | xxd -ps -c0)
executeMsg="{ \"save_data\": { \"save_data\": { \"data\": \"$dataHex\", \"da_height\": 0 } } }"; echo $executeMsg

babylond tx wasm execute $address "$executeMsg" --from=user --gas-prices=1ubbn --gas-adjustment=1.3 --chain-id="euphrates-0.5.0" -b=sync --yes --log_format=json --node=https://rpc-euphrates.devnet.babylonlabs.io

7. Query contract

babylond query wasm contract-state smart $address '{ "query_data": { "query_data": { "da_height": 0 } } }' --node=https://rpc-euphrates.devnet.babylonlabs.io -o json | jq -r '.'
