Fiber is designed to make self-custody actually usable.
Traditional self-custody gives users control over their assets, but the experience is often too difficult for mainstream users. Seed phrases, private keys, wallet recovery, gas, network switching, and complex transaction flows create unnecessary friction.
Fiber keeps the core benefit of self-custody - user control - while simplifying the experience around it.
What does non-custodial mean?
Non-custodial means that Fiber does not take ownership or custody of user funds.
In a custodial system, a company holds assets on behalf of users. The user has an account balance, but the custodian ultimately controls the wallet, private keys, withdrawals, and asset movement.
In a non-custodial system, the user remains in control of their assets. Funds are held through wallet infrastructure where the user, not Fiber, has authority over their money.
This is one of the core ideas behind crypto: users should be able to own and access their assets directly, without relying on a bank, exchange, or centralized platform to hold funds for them.
Fiber simplifies self-custody
Fiber uses enclave-based wallet infrastructure to make wallet creation, access, and recovery feel more like a modern app experience.
Instead of requiring users to manually manage a seed phrase from day one, Fiber can attach wallet access to familiar login methods such as phone or email.
This allows users to access their wallet more easily while remaining non-custodial.
The goal is simple: make self-custody feel as intuitive as using a normal financial app, without turning Fiber into a custodian.
How it works
At a high level:
- A user signs up using a phone number or email.
- A wallet is created through Fiber’s underlying enclave-based wallet infrastructure.
- The user can access and manage their assets inside the Fiber app.
- Fiber does not custody user funds.
- Fiber cannot freeze, move, or take control of user funds.
- Transactions require user authorization.
This gives users a simpler way to interact with onchain assets while preserving the ownership benefits of crypto.
User responsibility
Fiber makes self-custody easier, but it does not remove every responsibility that comes with owning and managing assets directly.
Users should still protect their devices, login methods, recovery methods, and app access.
Onchain transactions may be irreversible, and users should be careful when sending assets, using unsupported networks, or approving transactions.
Fiber’s role is to make self-custody as simple and safe as possible, not to remove every responsibility from the user.
Q&A
Is Fiber non-custodial?
Yes. Fiber is designed so users remain in control of their assets. Fiber does not custody user funds.
Do I need a seed phrase?
Fiber is designed to reduce the need for traditional seed phrase management. Instead, users can access and recover their wallet through familiar login methods such as phone or email.
Does Fiber hold my private keys?
Fiber does not custody user funds. Wallet access is managed through underlying enclave-based infrastructure designed to make self-custody easier while preserving user control.
Can Fiber freeze my funds?
No. Fiber cannot freeze user funds because Fiber does not custody user assets.
Can Fiber move my funds?
No. Fiber cannot move or withdraw user funds on the user’s behalf. Transactions require user authorization.
What happens if I lose access?
Fiber is designed to support easier recovery through familiar login methods such as phone or email.
The exact recovery flow may depend on the final implementation, but the goal is to make recovery simpler without compromising self-custody.
Is Fiber the same as a centralized exchange?
No. Centralized exchanges hold assets on behalf of users. Fiber is designed so users control their own assets through non-custodial wallet infrastructure.
Does self-custody mean there is no risk?
No. Self-custody gives users control, but users are still responsible for protecting access, devices, recovery methods, and transaction decisions.
Fiber makes this easier, but does not remove every responsibility that comes with managing assets directly.
