The transfer model Fiber is changing
A conventional stablecoin transfer can record the sending address, receiving address, amount or related data on a blockchain ledger, depending on the network and token design. Anyone can inspect that ledger.
An address may not print your legal name, but repeated activity, exchange records and shared payment details can make wallet relationships easier to infer. That is the exposure Fiber’s privacy layer is designed to reduce for supported activity.
The protected model Fiber uses
A privacy system moves supported assets into protected state and uses zero-knowledge proofs to demonstrate that a requested action is valid. The network verifies the proof without receiving all of the private financial inputs.
Fiber uses infrastructure based on a fork of Railgun for supported transfers, trades and earn activity. We keep the proof machinery behind the account experience so you can authorize the action without operating cryptographic tooling yourself.
What Fiber still asks you to verify
Privacy cannot correct the wrong asset, network or recipient. Check that Fiber supports the asset, network, receiving flow and intended action. Understand what the recipient sees and whether moving back to a public address changes the visibility of later activity.
- Supported stablecoin and blockchain
- Visibility of deposit and withdrawal events
- Recipient compatibility
- Network, proof and third-party fees
- Compliance or verification requirements
What Fiber privacy does not remove
Our private transfers remain subject to wallet security, smart-contract risk, stablecoin risk, applicable law and integrated-service policies. Verify addresses and amounts carefully because privacy does not make a blockchain transaction reversible.
Questions worth asking before the money moves.
Are USDC transfers visible to everyone?
Ordinary transfers on public blockchains generally create inspectable records. Fiber uses zero-knowledge proofs to protect supported activity, while the exact public fields still depend on the network and transaction design.
What does a zero-knowledge proof hide?
It lets Fiber prove that supported activity is valid without revealing the private inputs used to create the proof. The exact protected details depend on the implementation.
Are all Fiber transfers private?
No. We protect supported Fiber activity. Unsupported assets, public blockchain interactions and integrated services can have different visibility.
