Sling Money is a self-custody wallet. This means that all money stored in the Sling Wallet is secured using a private cryptographic key which only you can access. Sling Money cannot access your wallet, cannot initiate transactions on your behalf, and cannot control or access the funds in your wallet.
This is different than most financial products you may have used before, where money is stored by the service provider in a centralized ledger and the service provider may freeze those funds, lend those funds out, or otherwise manage those funds on your or their behalf. Avian Labs, the makers of Sling Money, have no access to your funds whatsoever. You are entirely in control.
Your Solana key used by your Sling Wallet is generated on your device during app setup. The key is securely stored on your device, encrypted with a key from the secure enclave on your device and protected with your biometrics.
Your key is backed up using a third-party service called Evervault. The backup is encrypted and the encrypted backup is stored separately from the decryption key.
You can take your Sling Wallet to any other provider any time you like by exporting your private keys from Evervault and then importing them into other wallet software such as Phantom. Just click on your avatar photo on the app, then click More and export your key.
