Crypto Hardware Wallets

Building credit is about protecting what you already have. With crypto, that means cold storage: keys kept on a device that never touches the open internet. Here is what a hardware wallet does, and how the three current Trezor models compare.

Why a hardware wallet

Keys stay offline. Your private keys are created and kept on the device, never on a computer, phone or exchange.
You approve every move. Each transaction is shown and confirmed on the device screen, so malware on your computer cannot quietly send coins away.
Lose the device, keep the coins. A recovery phrase written down at setup restores your wallet on a new device.
PIN and passphrase protection. A stolen device is useless without your PIN, and an optional passphrase adds a hidden second layer.
Thousands of coins and tokens. Bitcoin, Ethereum and thousands more, managed in the free Trezor Suite app.
Open source. Trezor publishes its firmware, so outside experts can check the code that guards your keys.

Worth knowing. Buy only from Trezor directly; a device from a third-party seller could be tampered with. Never type your recovery words into a computer, phone or website. Trezor will never ask for them, and fake Trezor websites are common, so check the address bar before you enter anything.

Credit, Rebuilt in Six Steps

Web3.credit looks at onchain reputation and decentralized identity, and what they could mean for people the old credit system leaves out.

0 of 6 complete

A traditional score is built from your borrowing history held by credit bureaus. No history often means no score, even for people who always pay their bills.

Credit score

Every repayment on a public blockchain leaves a permanent record. Some lenders look at a wallet's history to judge whether it repays reliably.

Onchain reputation

Decentralized identity lets you hold credentials yourself and share only what is needed, such as proving you are over 18 without showing your birth date.

Decentralized identity

Most crypto loans require more collateral than the loan. Reputation-based lending tries to lend with less, which works only if the borrower's record is trustworthy.

Under-collateralized loan

A public record can be read by anyone. Linking your identity to a wallet can reveal your full financial history, so share with care.

Public ledger

Onchain credit is still young. It shows promise for people shut out of the old system, but no onchain score replaces a bureau report for most loans today.
