# Graffiti

Heroglyph Graffiti is constructed with the following format:

* `#` precedes the tickers' names, separated by commas.
* `@` precedes the Graffiti Id's name.
* `-` precedes the global chain to execute all tickers on.

If `-` is missing, the default chain will automatically be used as global. If `#` or `@` are missing, the graffiti is invalid and won't be executed by Heroglyphs.

**Note:** You will have to pay the LayerZero fee on the target chain if you are not minting on Arbitrum.

Example of a valid graffiti: `#lueygi,69@atum-a` `#lueygi,69@atum` `#@atum`

Examples of invalid graffiti: `@atum-a` `#lueygi-a` `#lueygi@-a` `lueygi@atum`

### Advanced

You can override a specific ticker's execution chain by adding it after the ticker name: `#TickerNameA:OverriddenChain,TickerNameB@0xAtum`

For example: `#lueygi:h,69@atum` In this example, `lueygi` will be minted on **Base**, and `69` on **Arbitrum**.

### Cross-chain fee & claiming

When minting from another chain, you'll need to pay the layer-zero fee on the target chain, requiring extra steps.

For simplification, let's consider minting `lueygi` on `base`:

1. Switch to Base.
2. Approve WETH for `lueygi`.
3. Execute `lueygi.claimAction(srcChainLzEndpoint, [0])`.
   1. `[0]` is the id of the minting, for simplification, we will say this is our first time doing so

You'll pay the layer-zero fee with WETH and receive your token on the base chain
