CreateChainParams()

std::unique_ptr<const CChainParams> CreateChainParams	(	const ArgsManager &	args,
		const std::string &	chain
	)

Creates and returns a std::unique_ptr<CChainParams> of the chosen chain.

Returns

a CChainParams* of the chosen chain.

Exceptions

a	std::runtime_error if the chain is not supported.
