A seed phrase tool should earn trust by staying small.
YSeed's manifesto is a set of product constraints. It is not enough to say no telemetry. The tool must avoid becoming a wallet, a recovery suite, or a balance lure.
Direct answer
YSeed is built around a default-deny rule: if a feature requires storing, transmitting, deriving, or monetizing seed phrase data, it does not belong in the public website.
The five rules
- No phrase backend. The website must not receive seed phrases through an API, form, analytics event, or support flow.
- No phrase persistence. Generated phrases must not be written to localStorage, sessionStorage, cookies, URLs, or browser-visible history.
- No balance lure. YSeed must not promise funded phrases, scan balances, or ask users to paste real phrases for wallet lookups.
- No recovery-suite creep. Private keys, xpubs, derivation paths, and address lists stay outside the public app.
- No false confidence. Validation can prove structure, not safety, ownership, or funds.
Why narrow beats feature-heavy
Feature-heavy BIP39 tools can be useful for advanced recovery work, but the same power becomes a liability in a normal browser session. A user may not know whether a page is compromised, whether an extension is reading the DOM, or whether clipboard history is syncing to another device.
YSeed therefore optimizes for a smaller decision: generate or inspect a phrase structure, learn what it means, and leave no durable secret behind.
Trust does not mean "risk-free"
A browser-only tool can reduce server-side exposure, but it cannot repair a compromised device, malicious extension, screen recorder, bad backup process, or fake domain. For meaningful funds, use a hardware wallet unless you fully understand the offline browser threat model.
Manifesto FAQ
What does safe-by-refusal mean?
Safe-by-refusal means YSeed intentionally rejects features that would make the website more powerful but more dangerous for seed phrases, such as balance checks, private keys, xpubs, and phrase storage.
Why does YSeed discuss scams instead of hiding from those keywords?
People search for risky phrases like seed phrase generator with balance. YSeed answers those searches directly so users can recognize the scam pattern before they paste a real recovery phrase.
