Networks and testnet

	chainId	Money
BSC mainnet	56	real
BSC testnet	97	free, from the faucet

GET /api/v1/settings says which network the API is on, and gives every contract address. Read it at start; never hard-code an address or a fee.

Every transaction the API builds carries its chainId. A wallet on the wrong network will refuse it, which is the point.

Start every integration on testnet. Every example in these docs runs there before each release.
