# getAddresses

Returns all protocol contract addresses for a supported chain. Throws if the chain is not supported.

## Import

```ts
import { getAddresses } from '@railnetorg/railnet-sdk'
```

## Usage

```ts
import { base } from 'viem/chains'
import { getAddresses } from '@railnetorg/railnet-sdk'

const { conduitFactory, usdc, aaveV3VehicleFactory } = getAddresses(base.id)
```

### With spawnConduit

```ts
import { createWalletClient, http } from 'viem'
import { base } from 'viem/chains'
import { getAddresses, spawnConduit } from '@railnetorg/railnet-sdk'

const walletClient = createWalletClient({
  chain: base,
  transport: http(),
})

const { conduitFactory } = getAddresses(base.id)

const result = await spawnConduit(walletClient, {
  factory: conduitFactory,
  name: 'My Conduit',
  symbol: 'COND',
  vehicle: '0x...',
  initialExpectedSupply: 1000000n,
  transferEnabled: true,
  accessControl: '0x...',
  feeManager: '0x...',
  accountList: '0x...',
  ownerRegistry: '0x...',
  account: '0x...',
})
```

## Returns

`ChainAddresses`

An object containing all protocol contract addresses for the chain. See [`ChainAddresses`](/types/ChainAddresses).

## Parameters

### chainId

* **Type:** `number`

The chain ID to look up. Throws an error if the chain is not supported.

## Supported Chains

| Chain | Chain ID |
| --- | --- |
| Ethereum | `1` |
| Base | `8453` |

All addresses are defined in [`src/contracts/addresses.ts`](https://github.com/railnetorg/railnet-sdk/blob/main/src/contracts/addresses.ts).

## Error Handling

```ts
import { getAddresses, isSupportedChain } from '@railnetorg/railnet-sdk'

const chainId = 42161

if (isSupportedChain(chainId)) {
  const addresses = getAddresses(chainId)
}
```
