# Contract Addresses

The contracts below back Aligned's Proof Aggregation Service.

* `AlignedProofAggregationService` — receives aggregated proofs and answers proof inclusion checks.
* `AggregationModePaymentService` — receives deposits that fund your proof submission quota.

## Sepolia Deployments

| Contract                       | Address                                                                                                                       |
| ------------------------------ | ----------------------------------------------------------------------------------------------------------------------------- |
| AlignedProofAggregationService | [0xb5D46304c30B1AeB3a8Da6ab599c336f7946C8A4](https://sepolia.etherscan.io/address/0xb5D46304c30B1AeB3a8Da6ab599c336f7946C8A4) |

{% hint style="warning" %}
The CLI and SDK do not support Sepolia. The `--network` option accepts `devnet`, `hoodi` and `mainnet` only, and there is no Aggregation Mode Gateway deployed for Sepolia.
{% endhint %}

## Gateway URLs

Proofs are submitted to the Aggregation Mode Gateway. The CLI and SDK pick the right URL from the `--network` option, so you normally do not need these directly.

| Network | Gateway URL                                |
| ------- | ------------------------------------------ |
| Mainnet | `https://mainnet.gateway.alignedlayer.com` |
| Hoodi   | `https://hoodi.gateway.alignedlayer.com`   |
| Devnet  | `http://127.0.0.1:8089`                    |
