# Official addresses

> Klieg Wire access contracts and the USDC payment token on Base.

All access contracts below are on **Base Mainnet**, chain ID **8453**. They represent Klieg passes, not the tokens you research in the app.

## Current passes

**Demo · KliegDemoPass**

```text wrap theme={null}
0xE8E2F29c877526Ee04B8fe80a321F5732A6C250b
```

[Demo contract on BaseScan](https://basescan.org/address/0xE8E2F29c877526Ee04B8fe80a321F5732A6C250b).

**Standard V2 · KliegAccessPassV2**

```text wrap theme={null}
0xf6af9A1c218B2ef8f0075043c9D071ee5A29091c
```

**Gold · KliegGoldSupporter**

```text wrap theme={null}

```

## Payment token

Payments use USDC on Base with **6 decimals**:

```text wrap theme={null}
0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
```

[Open USDC on BaseScan](https://basescan.org/address/0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).

The purchase flow requests a USDC allowance for the selected **pass contract**. This is separate from an approval to transfer the NFT itself. USDC on another network cannot pay for a Base purchase.

## Legacy: Standard V1

```text wrap theme={null}
0x9646409d9B18E8A06aB37913218d13e87348FFBf
```

[Open V1 on BaseScan](https://basescan.org/address/0x9646409d9B18E8A06aB37913218d13e87348FFBf).

V1 sales and renewals are closed. The contract remains relevant to previously paid access; it is not the destination for new purchases. Sales closed at block **50,911,523** in [this transaction](https://basescan.org/tx/0xdcf20cdf074cbad49c79585a4d96925d04bb00f48ee503404af7e466fcdfe1e0).
