Adding Assets

If adding a new asset, please ensure the following:

• Asset is registered to the Cosmos Chain Registry.
• Add asset to bottom of zone_assets.json.
  • chain_name and base_denom are provided and use values exactly as defined at the Chain Registry.
  • path is provided, and the IBC channel referenced is registered at the Chain Registry (skip if native to Osmosis).
  • osmosis_verified is set to false
  • Optional: transfer_methods, peg_mechanism, override_properties, canonical, categories, where necessary (see README for details).
• I am aware that upgrading an asset to 'Verified' status requires an additional PR to this repo (checklist below).
