# Bridge

KII can move between Kiichain and supported external chains through Hyperlane warp routes. Use the addresses below to verify you are interacting with the correct contracts, and use [Nexus](https://nexus.hyperlane.xyz/?origin=kiichain\&originToken=KII\&destination=bsc\&destinationToken=KII) as a UI option for bridging assets.

## Bridge with Nexus

[Nexus](https://nexus.hyperlane.xyz/?origin=kiichain\&originToken=KII\&destination=bsc\&destinationToken=KII) is a Hyperlane-powered bridge interface. You can bridge KII between Kiichain and connected chains such as BNB Smart Chain (BSC), Polygon, Base, Ethereum, and Mantle.

Always confirm the destination chain and token address before signing a transaction.

## KII addresses on other chains

Official Hyperlane warp route configuration (source of truth):

* [Hyperlane registry — KII / kiichain-config.yaml](https://github.com/hyperlane-xyz/hyperlane-registry/blob/main/deployments/warp_routes/KII/kiichain-config.yaml)

| Chain                 | Contract address                             | Type                        |
| --------------------- | -------------------------------------------- | --------------------------- |
| Kiichain              | `0xEEC6574eAbBa52bac3f0277F2cD5Ac7e67197886` | Native (EvmHypNative)       |
| BNB Smart Chain (BSC) | `0xEEC6574eAbBa52bac3f0277F2cD5Ac7e67197886` | Synthetic (EvmHypSynthetic) |
| Polygon               | `0xEEC6574eAbBa52bac3f0277F2cD5Ac7e67197886` | Synthetic (EvmHypSynthetic) |
| Ethereum              | `0xEEC6574eAbBa52bac3f0277F2cD5Ac7e67197886` | Synthetic (EvmHypSynthetic) |
| Mantle                | `0xEEC6574eAbBa52bac3f0277F2cD5Ac7e67197886` | Synthetic (EvmHypSynthetic) |
| Base                  | `0x3EBA6644819546C44Eb3e7c3A92f034f921dcA80` | Synthetic (EvmHypSynthetic) |

On Kiichain, the warp route represents native KII. On other chains, the listed address is the synthetic KII token contract for that network.

Decimals are `18` on all listed chains. Symbol: `KII`.

## Safety checklist

* Prefer the Hyperlane registry link above when confirming addresses.
* Base uses a different contract address than the other listed chains.
* Do not send KII to an unverified or manually pasted address from unofficial sources.
* If a UI and the registry disagree, trust the [Hyperlane registry config](https://github.com/hyperlane-xyz/hyperlane-registry/blob/main/deployments/warp_routes/KII/kiichain-config.yaml).

# Agent Instructions
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.kiiglobal.io/docs/learn/getting-started/bridge.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.
