The most common case for this issue is the swapAsset or offrampAsset parameter set with the unsupported CHAIN_SYMBOL name, ie. using ETH_ETH on demo environment, or GOERLI_ETH and SEPOLIA_ETH on production environment.
Please use proper CHAIN_SYMBOL names in your widget configurations that can be provided by our on-ramp and off-ramp asset API endpoints respectively of the environment used.
Remember
Call the API endpoint on the desired environment you’re interested in.
Example
If you wish to call our API endpoints:
- on production you need to use https://api.ramp.network/api base url;
- and on demo you need to use https://api.demo.ramp.network/api base url
extended with the endpoint name you’re interested in like /host-api/v3/assets (for on-ramp assets) resulting in an exemplary urls being created:
- https://api.ramp.network/api/host-api/v3/assets to call assets on production
- and https://api.demo.ramp.network/api/host-api/v3/assets to call assets on demo environment.
To create a proper CHAIN_SYMBOL name for your widget configuration combine strings given in the chain and symbol keys returned in the API response using _ as a word connector resulting in the CHAIN_SYMBOL name being created.
