# Contract addresses

{% hint style="info" %}
DKG V10 runs on **Base Sepolia (testnet)**, and the final release-candidate contracts are also deployed on **Base mainnet** as a pre-mainnet deployment. The full mainnet launch across Base, Gnosis, and NeuroWeb is still upcoming — see the [V10 Mainnet Release Timeline](/origintrail-v9-v10/v10-mainnet-release-timeline.md). The mainnet TRAC addresses below are the existing token contracts on those chains (for reference and bridging); the Gnosis and NeuroWeb mainnet protocol contracts will be published at mainnet launch.
{% endhint %}

## TRAC token

TRAC is the ERC-20 utility token used across the DKG. The token contract address is different on each chain — use the one for the network your node operates on.

On **mainnet**, TRAC is the original token contract (unchanged from V8). On the active V10 testnet (**Base Sepolia**), V10 uses a freshly redeployed test-TRAC contract (different from the V8 one). NeuroWeb uses the same native TRAC address on both mainnet and testnet.

### Mainnet

| Network  | TRAC token address                           |
| -------- | -------------------------------------------- |
| Base     | `0xa81a52b4dda010896cdd386c7fbdc5cdc835ba23` |
| Gnosis   | `0xEddd81E0792E764501AaE206EB432399a0268DB5` |
| NeuroWeb | `0xFfFFFFff00000000000000000000000000000001` |

### Testnet

| Network          | TRAC token address                           |
| ---------------- | -------------------------------------------- |
| Base Sepolia     | `0x2A58BdD13176D85906D804cdbFFA0D9119282DC8` |
| Gnosis Chiado    | `0x9cFa71394906fa38399aD305E7Ca97b00e3b4449` |
| NeuroWeb Testnet | `0xFfFFFFff00000000000000000000000000000001` |

{% hint style="info" %}
The test-TRAC faucet currently serves **Base Sepolia** only — that is the active V10 testnet. The Gnosis Chiado and NeuroWeb testnet addresses above are the existing test-token contracts (NeuroWeb uses the same address on mainnet and testnet). See the [deployments folder](https://github.com/OriginTrail/dkg/tree/main/packages/evm-module/deployments/README.md) for the canonical addresses.
{% endhint %}

## DKG smart contracts

The full set of DKG V10 contract deployments (Hub, Staking, Conviction, Random Sampling, ParametersStorage, …) lives in [`packages/evm-module/deployments`](https://github.com/OriginTrail/dkg/tree/main/packages/evm-module/deployments/README.md) — one file per network, listing every contract's on-chain address, version, and deployment block.

The **Hub** is the entry point — it resolves the addresses of every other V10 contract on a given network, so in most cases the Hub address is all you need. Note that V10 Hub addresses are **new** (they differ from V8 on every network, including mainnet).

| Network                | V10 Hub address                              |
| ---------------------- | -------------------------------------------- |
| Base (mainnet)         | `0x26146f51e31a95c075228a34cfc696f09e4c36c3` |
| Base Sepolia (testnet) | `0xC056e67Da4F51377Ad1B01f50F655fFdcCD809F6` |

{% hint style="info" %}
The Base mainnet Hub above is the pre-mainnet release-candidate deployment. Gnosis and NeuroWeb mainnet Hub addresses are published in the [deployments folder](https://github.com/OriginTrail/dkg/tree/main/packages/evm-module/deployments/README.md) as those networks' V10 contracts go live — use that folder as the source of truth.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.origintrail.io/general/contract-addresses.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
