## Supported Tokens

Ekiden supports the following tokens as margin collateral:

* USDCx.
* More coming soon.

Check the documentation for the most current list of supported collateral assets.

## Depositing Tokens

### Steps

* Ensure Wallet Connection to the correct network

Deposit and withdrawal integrations for Canton are being finalized. Updated integration instructions and SDK examples will be added once available.

{/* TODO(SDK): Replace the legacy Aptos deposit and withdrawal flows with the current Canton integration once the SDK implementation is available. */}
