List all code blobs

junod query wasm list-code --chain-id=juno-1 --node="tcp://88.99.164.158:1067"

Show code info of code blob with identifier 100

junod query wasm code-info 100 --chain-id=juno-1 --node="tcp://88.99.164.158:1067"

Show pinned code blobs

junod query wasm pinned --chain-id=juno-1 --node="tcp://88.99.164.158:1067"

List instances of contracts instantiated from code with identifier 1

junod query wasm list-contract-by-code 1 --chain-id=juno-1 --node="tcp://88.99.164.158:1067"

Osmosis

Show wasm parameters

osmosisd query wasm params --chain-id=osmosis-1 --node="https://rpc.osmosis.zone:443"

List all code blobs

osmosisd query wasm list-code --chain-id=osmosis-1 --node="https://rpc.osmosis.zone:443"

Show code info of code blob with identifier 100

osmosisd query wasm code-info 100 --chain-id=osmosis-1 --node="https://rpc.osmosis.zone:443"

Show pinned code blobs

osmosisd query wasm pinned --chain-id=osmosis-1 --node="https://rpc.osmosis.zone:443"

Download code blob for contract with code id = 7 and save to file code12.wasm

osmosisd query wasm code 7 code12.wasm --chain-id=osmosis-1 --node="https://rpc.osmosis.zone:443"

List instances of contracts instantiated from code with identifier 100

osmosisd query wasm list-contract-by-code 100 --chain-id=osmosis-1 --node="https://rpc.osmosis.zone:443"

Query contract state

//wrong
osmosisd query wasm contract-state smart osmo1xwahguax578tvequeg70xn0ej78gn2ahugq92m7dx8hkklsyupmsqqh66x '{"all_tokens":{}}' --chain-id=osmosis-1 --node="https://rpc.osmosis.zone:443"

//correct
osmosisd query wasm contract-state smart osmo1xwahguax578tvequeg70xn0ej78gn2ahugq92m7dx8hkklsyupmsqqh66x '{"list_proposals":{}}' --chain-id=osmosis-1 --node="https://rpc.osmosis.zone:443" 

Wasmd

Creating single-node blockchain locally

Original instructions can be found here.

Below are the ones used on Linux, based on the general instructions.

Go to wasmd folder of freshly cloned repository.

git clone https://github.com/CosmWasm/wasmd.git
cd wasmd
make install
sudo ln -s ~/go/bin/wasmd /usr/local/bin/wasmd
cd scripts/contrib/local
setup_wasmd.sh
start_node.sh

All the chain configuration files are stored in ~/.wasmd. To start the configuration from the very beginning, just remove this directory:

rm -rf ~/.wasmd

To list all smart contact codes on the chain, run:

wasmd query wasm list-code

Output:

code_infos: []
pagination:
  next_key: null
  total: "0"
