You can create a Starknet chain adapter from either a starknet.js account or as a shortcut from a private key.

​
From account

Use this method to use connected wallets in webapps or if you want to set up an account yourself. 
import { getStarknetChainAdapterFromAccount } from '@rhino.fi/sdk/adapters/starknet'

const chainAdapter = getStarknetChainAdapterFromAccount(
  account,
  chainConfig
)

​
From private key

Use this method as a shortcut to setting up an account yourself. 
import { getStarknetChainAdapterFromPrivateKey } from '@rhino.fi/sdk/adapters/starknet'

const chainAdapter = getStarknetChainAdapterFromPrivateKey(
  'YOUR_PRIVATE_KEY',
  chainConfig
)

​
Options

Both functions also accept a 3rd options parameter. Currently it only includes a tokenAllowanceOverride property that allows you to specify a higher token allowance to be used instead of the calculated one. This can be useful to optimize gas usage by setting bigger allowances that will last for multiple bridges.
