cosmjs-utils

CosmJS utilities

``
yarn add cosmjs-utils
`


Creating Signers

To broadcast messages, you'll want to use either keplr or an OfflineSigner from cosmjs using mnemonics.


$3

Likely you'll want to use the Amino, so unless you need proto, you should use this one:

`js
import { getOfflineSignerAmino as getOfflineSigner } from 'cosmjs-utils';
`


$3

`js
import { getOfflineSignerProto as getOfflineSigner } from 'cosmjs-utils';
`

WARNING: NOT RECOMMENDED TO USE PLAIN-TEXT MNEMONICS. Please take care of your security and use best practices such as AES encryption and/or methods from 12factor applications.

`js
import { chains } from 'chain-registry';

const mnemonic =
'unfold client turtle either pilot stock floor glow toward bullet car science';
const chain = chains.find(({ chain_name }) => chain_name === 'osmosis');
const signer = await getOfflineSigner({
mnemonic,
chain
});
`

Broadcasting messages

Now that you have your client, you can broadcast messages:

`js
import { signAndBroadcast } from 'cosmjs-utils';

const res = await signAndBroadcast({
client, // SigningStargateClient
chainId: 'osmosis-1', // use 'osmo-test-4' for testnet
address,
msgs: [msg],
fee,
memo: ''
});
