All stablecoin transfers in and out of Sling Money are performed using disposable Transfer wallets, which were explicitly created to facilitate third-party wallet transfers.
Step by step
Tap your avatar icon
Tap 'Transfer wallet details'
If you do not have a transfer wallet created, you will be asked to create one.
Once created, you can:
Scan the QR code or copy the wallet name to add stablecoins
or
Generate a new transfer wallet
Transfer Wallets are self-custodial, just like your Primary Wallet, and you may export the key(s) for your Transfer Wallets at any time.
