# FAQ

> Straight answers to the questions developers ask most: custody, availability, the key model, what you can sign, storage, and recovery.

These are the questions we hear most when teams build on WalletSuite MPC.

<AccordionGroup>
  <Accordion title="Can WalletSuite move my users' funds?" icon="lock">
    No. Every wallet is self-custodial. You hold the wallet and WalletSuite holds a co-signing share, and both are needed to sign. WalletSuite can never sign alone, so it never has custody of your users' funds. See [Shares & thresholds](/mpc/key-shares).
  </Accordion>

  <Accordion title="Is the full private key ever assembled?" icon="key-skeleton">
    No. There is no moment where a full private key exists on any machine. Each side holds its own share, and a signature is produced jointly without either share ever leaving its owner. One stolen share is useless on its own. It reveals nothing about the key and cannot move funds.
  </Accordion>

  <Accordion title="What happens if WalletSuite is unavailable?" icon="plug-circle-exclamation">
    Your funds stay safe and nothing is lost. Signing pauses because both shares are needed to sign. The wallet stays valid, the on-chain balance is untouched, and signing resumes the moment the service is reachable again.
  </Accordion>

  <Accordion title="What can I sign?" icon="signature">
    You sign transactions across 84 chains including Ethereum, Base, Bitcoin, Solana, Tron, and more. One wallet works everywhere. See [Supported chains](/supported-chains) for the full list and [Signing](/mpc/signing) for the developer flow.
  </Accordion>

  <Accordion title="Where should I store the wallet?" icon="database">
    In durable storage you control, never a temp directory, and keep a secure backup. The SDK returns the wallet as an opaque blob and does not persist it, so you pass it back on every operation. Good homes include your database, a KMS or HSM, the user's device, or a passkey-wrapped envelope. Your secure backup is your recovery. For patterns, see [Shares & thresholds](/mpc/key-shares).
  </Accordion>

  <Accordion title="Can I export the private key?" icon="file-export">
    There is no full private key to export, by design, so there is nothing for a stolen export to drain. For a managed recovery path, see [Recovery](/mpc/recovery).
  </Accordion>

  <Accordion title="Can a lost wallet be recovered?" icon="life-ring">
    Yes. Your secure backup of the wallet is your recovery: restore it from durable storage and signing resumes. Keep the wallet backed up and out of temp directories. A managed recovery path is available as an opt-in under separate commercial terms. See [Recovery](/mpc/recovery).
