# EVM Integrations

The `EthereumProvider` defined in Tomo Connect SDK contains all the necessary functions to interact with EVM chains. Core functions are:

### requestAddresses

Implemented `eth_requestAccounts`

```javascript
public async requestAddresses()
```

### getAddresses

Implemented `eth_accounts`

```javascript
public async getAddresses()
```

### signMessage

Implemented `personal_sign`

```javascript
public async signMessage(msg: string, address: string)
```

### signTypedData

Implemented `eth_signTypedData_v4`

```javascript
public async signTypedData(address: string, msg: string)
```

### sendTransaction

Implemented `eth_sendTransaction`

```javascript
export interface EvmTxParams {
  from: string,
  to: string,
  value: string,
  gasPrice?: string,
  gasLimit?: string,
  maxFeePerGas?: string,
  maxPriorityFeePerGas?: string,
  data?: string,
}

public async sendTransaction(params: EvmTxParams)
```

### sendRawTransaction

Implemented `eth_sendRawTransaction`

```javascript
public async sendRawTransaction(signedTx: string) 
```

### swithChain

Implemented `wallet_switchEthereumChain`

```javascript
public async swithChain(chainId: string)
```

### recoverMessageAddress

Implemented `personal_ecRecover`

```javascript
public async recoverMessageAddress(message: string, signature: string)
```

Also EthereumProvider is a provider compatible with EIP 1193. It can be integrated with third-party libraries like viem, ethers, just like window\.ethereum.

```
// Integrated with viem
const client = createWalletClient({
  chain: mainnet,
  transport: custom(tomoSDK.ethereumProvider)
})
```
