FAQ

This is a list of Frequently Asked Questions for the Amarok public testnet.

What chains are supported?​

An updated list can be found at Supported Chains.

What assets are supported?​

See the deployed addresses for assets at Deployed Contract Addresses.

What are token "flavors"?​

How do I find the canonical details of a token?​

The canonical domainId and tokenId of a token can be found by calling the getTokenId function of TokenRegistry.

Example:

  • The token of interest is TestERC20 (0x7ea6eA49B0b0Ae9c5db7907d139D9Cd3439862a1) on Goerli. We want to figure out its canonical domainId and tokenId.

  • Find the Connext contract address on Goerli from here, click its link to open up the Diamond Inspector on Louper.

  • Find the TokenFacet and click the "Read" button.

  • Select the getTokenId method and input the TestERC20 address to obtain its canonical details.

  • Alternatively, you can call getTokenId using a tool like Foundry's cast to read from the contract.

    cast call --chain goerli 0x99A784d082476E551E5fc918ce3d849f2b8e89B6 "getTokenId(address)(uint32,bytes32)" "0x7ea6eA49B0b0Ae9c5db7907d139D9Cd3439862a1" --rpc-url <goerli_rpc_url>

    Returns:

    1735353714 # the canonical domainId is Goerli
    0x0000000000000000000000007ea6ea49b0b0ae9c5db7907d139d9cd3439862a1 # the canonical bytes32 tokenId

What if I just want to test the destination-side target function?​

If there’s no token transfer involved then just set transactingAssetId: address(0) and amount: 0.

Do I need to do anything with the AMB contracts?​

No, you do not need to deploy or even interact with AMB contracts directly.

How do I find the different domainIds?​

See Domain IDs.

Where are the Connext contracts?​

See Deployed Contract Addresses.

How do I take my token crosschain?​

There are a few steps to take, so please reach out to us for assistance:

  • The Connext team whitelists your asset (for now, this is required).
  • You transfer some of the assets across the bridge.
  • If the destination asset has the amb flavored asset as the adopted asset (there's no existing pool, no representative asset exists yet), then the Token Registry will deploy a new token and set it as canonical.

Are there size limits to calldata?​

Yes and the details will be posted soon.
