Custodial or self-custody, what’s safer?

Custodial is simpler but introduces platform risk. Self-custody removes that risk, but you must secure keys. MPC/AA blends both: easier recovery without a single point of failure.

Are MPC wallets truly seedless?

Yes, no single seed exists. Multiple shards sign together. Still back up recovery methods (device, email, guardian, or second shard).

What if I lose my phone?

With MPC/AA , use your recovery factor (passkey/guardian/hardware) to restore on a new device. With seed wallets, use your 12/24 words, stored offline.

Can I pay fees without holding the chain’s gas token?

Many modern wallets support sponsored gas or fee abstraction, so you can pay in stablecoins or let the dApp cover it.

Do I need a hardware wallet?

For meaningful savings, yes. Keep a hardware vault for long-term funds; a mobile AA/MPC wallet for spending.
