@cosmology/cli

npm install -g @cosmology/cli

Use cosmology to build web3 applications on top of Osmosis and the Cosmos. Make cryptocurrency trades, join liquidity pools, and stake rewards.

usage

CLI and user prompts

Not sure what to do? Simply type cosmology. It will prompt you with options.

$ cosmology 
? [cmd] what do you want to do? 
  keychain-del 
  keychain-get 
  keychain-set 
❯ list-apis 
  list-pools 
  list-prices 
  load-recipe 

Then once you learn the api, you can start supplying the parameters.

cosmology <commandname>

commands

rebalance

The rebalance command will make a series of swaps on your behalf. It will prompt you to choose the coins you are willing to sell to create a new balance based on the pools you want to enter.

cosmology rebalance 

Example with parameters

cosmology rebalance \
    --chainId osmosis-1 \
    --restEndpoint https://lcd-osmosis.blockapsis.com \
    --rpcEndpoint https://osmosis.validator.network \
    --slippage 1 

join

The join command will join a pool.

cosmology join 

Example with parameters

cosmology join \
    --keychain my-mnemonic-name \
    --chainId osmosis-1 \
    --restEndpoint https://lcd-osmosis.blockapsis.com \
    --poolId 601
    --max

lock

The lock command will lock your gamms tokens for staking so you can earn rewards.

cosmology lock 

Example with parameters

cosmology lock \
    --keychain my-mnemonic-name \
    --chainId osmosis-1 \
    --restEndpoint https://lcd-osmosis.blockapsis.com \
    --poolId 601 \
    --duration 14

claim

Claim rewards from staking.

cosmology claim

Example with parameters

cosmology claim \
  --keychain my-mnemonic-name \
  --chainToken CMDX \
  --minAmount 1 \
  --restEndpoint https://rest.comdex.one \
  --rpcEndpoint https://rpc.comdex.one

delegate

Stake tokens to a validator.

cosmology delegate

Example with parameters

cosmology delegate \
  --keychain my-mnemonic-name \
  --chainToken CMDX \
  --minAmount 1 \
  --restEndpoint https://rest.comdex.one \
  --rpcEndpoint https://rpc.comdex.one \
  --validatorAddress comdexvaloper1mzxzxkzajancc63gtwt9x9zw2qfv9k9ar7ka34

env vars

While everything can be done with parameters, you can also just supply env vars and cosmology won't prompt you for those values:

| env var | optional | description | | -------------------- | ------------------ | --------------------------------------------------------- | | MNEMONIC | Yes | cosmos mnemonic, either plain-text or encrypted | | ENCRYPTED_SALT | Yes | used for encrypting/decrypting mnemonics | | KEYCHAIN_ACCOUNT | Yes | used for storing info in OSX keychain account | | CHAIN_ID | Yes | used for getting chain info, e.g. osmosis-1 | | REST_ENDPOINT | Yes | used for setting LCD endpoint | | RPC_ENDPOINT | Yes | used for setting RCP endpoint |

mnemonics

There are a few methods to deal with mnemonics.

1. plain text env var MNEMONIC
2. encrypted key with a salt
3. mac OSX keychain

METHOD 1 - plain text

(Not recommended) video here

export MNEMONIC="action brisk disagree just bunker design wasp hand night ghost runway fluid"
# now you can run cosmology

cosmology rebalance

METHOD 2 - encrypted salt via env var ENCRYPTED_SALT

video here

The encrypted salt is the recommended usage so that you don't store plain-text mnemonics.

1 First, generate a salt.

cosmology salt-generate --saltBytes 64
> GRHeG5r9nojio7PmCuNnLEh0Hglwvw1Bn87ipIMeyhPFVJk9i5eWtno7m7pa8FPRjbsd2LqCjEsR8/Hiyp9lLg==

2 Now encrypt this salt value

(Yes, we are encrypting a salt with a salt, or password)

cosmology salt-encrypt \
     --secret GRHeG5r9nojio7PmCuNnLEh0Hglwvw1Bn87ipIMeyhPFVJk9i5eWtno7m7pa8FPRjbsd2LqCjEsR8/Hiyp9lLg==

Now, store that value securely, and remember your password. Test the salt-encrypt and salt-decrypt commands a few times so you understand how it works.

3 Now you can use it in env var ENCRYPTED_SALT

export ENCRYPTED_SALT=U2FsdGVkX183aSMtLlWua/uig/Qqd99TBILc63iW1AsJaKGykZGPvA/DXByjYtws7drSVlipMPsMLrePajBtRyFP7tZOLrlUuL+xlhcsRAm0DcTRV+VDsnDQVykSDhSyl1RYf03SsLgUsYMvsixWFA==

# now the user will be prompted for "salt" which is the password used to decrypt the encryption key
# the mnemonic will be automatically decrypted by the system
cosmology

METHOD 3 - keychain

video here

We can leverage the Mac OSX keychain. Don't worry though, we ONLY use encryption via the encrypted salt, even if some of you happen to trust storing mnemonics in OSX keychain. We only store encrypted values, period.

1 create an encryption key and encrypt it as described in the previous step

create an ENCRYPTED_SALT and store it securely.

2 add your mnemonic to your keychain

• name is how you'll reference
• password is your actual mnemonic
• salt is the salt for your encrypted salt key

$ cosmology keychain-set
? [name] name my-special-mnemonic-name-1
? [password] password [hidden]
? [salt] enter the salt [hidden]

Test it!

$ cosmology keychain-get \
 --name my-special-mnemonic-name-1

testing

first start the tests

cd ./packages/cosmology
yarn test:watch

hit "p" and then type a search string to scope to the name your test

developing the CLI

if you need to edit the CLI

cd ./packages/cosmology
export MNEMONIC="mammal wrestle hybrid cart choose flee transfer filter fly object swamp rookie"
export CHAIN_ID=osmosis-testnet-0
export RPC_ENDPOINT=http://143.244.147.126:26657

yarn run dev

known issues

• defaults to NOT using pools with less than 100k in liquidity
• smaller tokens with volatility may need higher slippage values
