Supported chains and tokens - Calm

Every onramp delivers to any chain on this page, except where the Supported onramps table says otherwise. Set the destination once on <CalmProvider> with chain and destinationToken.

Destination Token

The four tokens available for deposit settlement. Every onramp converts the user’s payment method, whether card, bank transfer, Cash App, or another token, into one of these tokens on your configured chain. USDC is available on seven of the eight supported chains, while each of the other three tokens is available on a single chain.

Token	Name	Decimals	Chains
USDC	USD Coin	6, 8 on HyperCore	Ethereum, Base, HyperEVM, HyperCore, Monad, Polygon, Arbitrum
USDC.e	Bridged USDC	6	Polygon
AUSD	Agora Dollar	6	Monad
USDm	USDm	18	MegaETH

These symbols are the literal values destinationToken takes, and the values the API’s destination_token field carries.

Swap source chains
