Frequently Asked Questions
Everything you need to know about BCH vanity addresses — wallets, exchanges, security, scams, and best practices.
TL;DR
- A vanity BCH address is a normal address that just starts with a pattern (e.g., qcash…).
- With our split‑key method, you never share your private key. We only need your compressed public key A.
- Most wallets treat vanity addresses like any other BCH address; for exchanges, always test with a small amount first.
- Never enter a seed phrase or private key on a website — ours or anyone else’s.
Using vanity addresses
What exactly is a vanity address?
It’s a standard BCH address whose CashAddr string begins with a readable prefix (e.g., bitcoincash:qcash…). Functionally it’s identical to any valid BCH address.
Does a vanity address weaken security?
No — not when generated with a proper split‑key process. We search for a small b and you combine A + b·G locally. Your private key never leaves your control.
CashAddr vs. legacy format?
BCH uses CashAddr (the bitcoincash: format). Some sites require the prefix, some don’t. Your address can be converted between CashAddr and legacy formats without changing the underlying key.
Upper/lowercase rules?
CashAddr is lowercase by convention. Vanity prefixes are compared lowercase; uppercase is typically normalized.
Wallets & Exchanges
Can I receive from an exchange to my vanity address?
Usually yes, as long as the exchange supports BCH deposits and accepts a standard CashAddr formatted address. Always send a small test amount first and verify the network is BCH (not BTC or BSV).
Can I send from my vanity address to an exchange?
Yes. When sending out, the exchange only cares that you’re depositing to the exchange’s own BCH deposit address. Your sender address being vanity doesn’t matter to them.
Coinbase specifically?
Exchange policies change. Confirm in the exchange’s help center that BCH deposits/withdrawals are supported and whether they require the bitcoincash: prefix. If in doubt, open a small test deposit first.
Best practice for exchanges?
- Always start with a tiny test (e.g., ~$1 equivalent).
- Double‑check the network (BCH) and address format (CashAddr).
- Copy/paste addresses; avoid manual typing; validate with wallet QR where possible.
- Wait for on‑chain confirmations the exchange requires before sending more.
Avoiding scams & protecting keys
How do I avoid fake “vanity” sites that steal keys?
- Never paste a seed phrase or private key into any website.
- Legit services (like ours) ask only for a compressed public key — not your private key.
- Verify you are on the correct domain over HTTPS. Beware look‑alike domains.
- Check for PGP‑signed deliverables and verify signatures.
- If using open‑source verify tools, run them locally (offline if you can).
What’s the safest way to hold the key for a vanity address?
- Prefer a hardware wallet or an air‑gapped setup.
- Back up your seed phrase securely (paper + fire/water safe, or Shamir splits if supported).
- Keep OS and wallet software updated; enable PIN/biometrics.
- For public donation addresses, assume privacy is reduced; use separate wallets for personal funds.
Service details
What information do you need from me?
Your compressed public key A and desired prefix. Optionally a PGP public key for encrypted delivery and an email for notifications.
Can you spend from my vanity address?
No. We never see your private key. We only return b and a signed report. You combine locally and control the resulting key entirely.
How does prefix length affect price/time?
Shorter prefixes (3–5 chars) are fast and inexpensive. 6+ becomes research‑grade. See Pricing for ballparks.
Multi‑coin?
BCH first. Additional chains are planned. We’ll announce when ready.
