## <a name="initialization">Initialization</a>

### Instantiate an EthAdapter

First of all, we need to create an `EthAdapter`, which contains all the required utilities for the SDKs to interact with the blockchain. It acts as a wrapper for [web3.js](https://web3js.readthedocs.io/) or [ethers.js](https://docs.ethers.io/v5/) Ethereum libraries.

Depending on the library used by the Dapp, there are two options:

- [Create an `EthersAdapter` instance](https://github.com/safe-global/safe-core-sdk/tree/main/packages/safe-ethers-lib#initialization)
- [Create a `Web3Adapter` instance](https://github.com/safe-global/safe-core-sdk/tree/main/packages/safe-web3-lib#initialization)

Once the instance of `EthersAdapter` or `Web3Adapter` is created, it can be used in the SDK initialization.

### Initialize the SafeServiceClient

```js
import SafeServiceClient from '@safe-global/safe-service-client'

const safeService = new SafeServiceClient({
  txServiceUrl: 'https://safe-transaction-mainnet.safe.global',
  ethAdapter
})
```
