Non-custodial

Self-custody is only useful if people can actually use it.

Classic wallets hand you a seed phrase and call that freedom. For a lot of users it is just a new way to lose money. Fiber keeps the ownership property and changes the access path: phone or email onboarding on top of enclave-based wallet infrastructure.

What non-custodial means here

Non-custodial means Fiber does not take ownership of your funds.

In a custodial system, the company holds assets on your behalf. You see a balance. They control the keys, the withdrawals, and the freeze button.

In Fiber, authority over funds stays with the user. Wallet access is constructed so Fiber cannot move assets unless you authorize the action. That is the line we care about.

How the simplified path works

At a high level:

1. You sign up with a phone number or email.
2. A wallet is created through Fiber’s enclave-based infrastructure.
3. You manage assets inside the app.
4. Fiber does not custody the funds.
5. Fiber cannot freeze or move funds on its own.
6. Transactions require your authorization.

The goal is boring on purpose: self-custody that feels like opening a normal finance app.

Details of the key split and signing path live in Security and Wallet infrastructure.

What still remains your job

Simplifying custody is not the same as deleting responsibility.

You still need to protect your device, login methods, recovery path, and the transactions you approve. Onchain transfers can be irreversible. Sending on the wrong network, or approving the wrong thing, is still a user-shaped failure mode.

Fiber tries to make the safe path the obvious path. It does not pretend the safe path is magical.

Direct answers

Is Fiber non-custodial?
Yes. Fiber is designed so users remain in control of their assets.

Do I need a seed phrase on day one?
No. Access and recovery are built around familiar login methods such as phone or email.

Does Fiber hold my private keys in a way that lets it spend?
No. Keys are handled through enclave-based infrastructure so Fiber cannot unilaterally move funds.

Can Fiber freeze or move my funds?
No. Fiber does not custody user assets and cannot initiate unauthorized actions.

Is this just a centralized exchange with nicer copy?
No. An exchange holds balances for you. Fiber is built so you control the assets through non-custodial wallet infrastructure.

Does self-custody mean no risk?
No. It means a different risk surface: less platform seizure risk, more personal access and transaction hygiene.
