# Tokens and Chains

Get a list of supported tokens, optionally filtered by chain ID.

```typescript
interface TokensParams {
  chainId?: string;
}

//Example implementation
const tokens = await getTokens();// to fetch all tokens from all chains
const tokens = await getTokens("1");// to fetch all tokens from chain 1

//Example response
{
  "status": "success",
  "data":{
    "1":[
      {
    "networkType": "evm",
    "address": "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee",
