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
