# Paradex Chain Adapter

### Prerequisites

You will need to install the [Paradex SDK](https://www.npmjs.com/package/@paradex/sdk) to instantiate a Paradex chain adapter. As Paradex can derive an account from either a Starknet or an EVM based signature, you have two options of initializing a Paradex account to be passed into the chain adapter function.

<CodeGroup>
  ```typescript From Starknet account theme={null}
  import { Account, Config, ParaclearProvider } from '@paradex/sdk'

  const config = Config.fetchConfig('prod')
  const paradexAccount = await Account.fromStarknetAccount(
    {
      provider: new ParaclearProvider.DefaultProvider(config),
      config,
      account // your starknet.js account
    },
  )
  ```

  ```typescript From EVM account theme={null}
  import { Account, Config, ParaclearProvider, Signer } from '@paradex/sdk'

  const config = await Config.fetchConfig('prod')
  const account = await Account.fromEthSigner({
    provider: new ParaclearProvider.DefaultProvider(config),
    config,
    signer: Signer.ethersSignerAdapter(ethersSigner) // Pass your ethers signer here
  })
  ```
</CodeGroup>

Once you have your Paradex account object set up, you can create the chain adapter from it:

```typescript theme={null}
import { getParadexChainAdapterFromAccount } from '@rhino.fi/sdk/adapters/paradex'

const chainAdapter = getParadexChainAdapterFromAccount(
  paradexAccount,
  chainConfig
)
```
