Unsupported chain: The chain id or slug is not in LayerHop's chain registry, or a provider does not serve it.

HTTP status	Retry
`400`	no

Where it comes from: GET /v1/tokens, GET /v1/quote; also mapped from provider errors (for example Relay CHAIN_DISABLED).

Causes#

srcChain, dstChain or chain is not one of the supported chains — for example a testnet id, or a typo in the slug.
GET /v1/tokens was called without chain.

How to fix#

Use a slug or id from GET /v1/chains. Solana is solana or 7565164.
Testnets are not supported yet — see the FAQ.
