CosmWasm Node Setup

Here we describe how to initialize accounts and balances on a CosmWasm blockchain.

We'll assume you're using wasmd but it could be neutrond or any other.

We'll also assume your chain ID is testing.

Run wasmd init <your name> --chain-id testing to initialize the local wasmd folder.

Now open the file ~/.wasmd/config/client.toml and change the field keyring-backend from os to test:

keyring-backend = "test"

Now, finally, we can create a local admin key for your wasmd. You'll use this to deploy contracts:

wasmd keys add admin

This should output a wasm address.

Now either you will setup a local testnet or use an existing testnet. If its an existing testnet, you need to fund this account. Send this address to someone who has access to the admin account for your testnet. If you have access yourself you can send funds yourself:

wasmd tx bank send <sender key name> <recipient address> <amount ucosm> --chain-id testing -y

If you're setting up your own local testnet, continue with the following:

# generate a second key for the validator
wasmd keys add validator

# fund both accounts in genesis
wasmd genesis add-genesis-account admin 100000000000stake,100000000000ucosm
wasmd genesis add-genesis-account validator 100000000000stake,100000000000ucosm

# sign genesis tx from validator and compose genesis
wasmd genesis gentx validator 100000000stake --chain-id testing
wasmd genesis collect-gentxs

Before finally starting the node, for it to work with the front end, you need to configure CORS.

In ~/.wasmd/config/config.toml, you'll need to make sure the listen address binds to the public IP (0.0.0.0) and the CORS allows all origins:

[rpc]
laddr = "tcp://0.0.0.0:26657"
cors_allowed_origins = ["*"]

And in ~/.wasmd/config/app.toml:

[api]
enable = true
address = "tcp://0.0.0.0:1317"
enabled-unsafe-cors = true

Now, finally:

wasmd start

And you should have a chain making blocks!

You can also reduce the block time by lowering timeout_commit in ~/.wasmd/config/config.toml.

Now that you have the chain running, you can start running the enclave and proxy in other windows.
