Designed to protect holders
at every step.
Blind signing is blocked. Not warned — blocked.
If we cannot describe a transaction in plain English, we refuse to sign it. No override. No "proceed anyway." Completely blocked.
Your IP stays yours.
Every request routes through a privacy proxy. Alchemy and CoinGecko never see your IP address.
Plain English, every time.
Every transaction is described in plain English before you confirm. You always know exactly what you are signing.
Security runs deeper
than a single feature.
Read-only by default
Opens in view mode every time. Sending requires your PIN — no exceptions.
Known-bad address blocking
Every recipient is checked against a community threat feed before the send screen appears.
30-day backup reminder
A built-in alarm tests your seed phrase backup every 30 days. No skip — only snooze.
Cost basis & P&L
Unrealized gains, cost basis, and time held — the analytics a holder actually needs.
Three steps to start
holding safely.
Install Heldby
Add the extension from the Chrome Web Store. Pinned to your toolbar in under a minute.
Create your wallet
Generate a new 12-word seed phrase. All key generation happens on your device — your keys never leave.
Back up your seed phrase
Verify your backup with a 3-word spot check. Heldby will remind you to re-test it every 30 days.
Security is the product.
Not a checkbox.
Heldby was built by someone with a security background who was tired of wallets that treat phishing as an edge case.
Keys never leave your device
Private keys and mnemonics are encrypted with AES-256-GCM and stored locally. Nothing is ever sent to a server.
No address or balance logging
We log nothing. No analytics, no telemetry, no third-party SDKs that phone home with your data.
10-second contract review window
Any transaction to a smart contract triggers a mandatory delay. Time to think before you sign.

Real feedback from holders who wanted a wallet that protects them by default — not one that just gets out of the way.
Add to Chrome“Finally a wallet that explains what I'm signing in plain English. Other wallets just throw hex data at you and hope you trust them.”
Mark R.
Long-term ETH holder
“The read-only default is brilliant. I open it to check my portfolio a dozen times a day without any risk of accidentally signing something.”
Sarah K.
Crypto newcomer
“Heldby blocked my very first attempt at sending to a bad address. Turned out it was a known drainer. I would have lost everything.”
David L.
Security-conscious holder
“The privacy proxy was the deciding factor. I don't want Alchemy or anyone else correlating my IP with my wallet address.”
Alex M.
Privacy advocate
“The cost basis tracking is exactly what I needed. I finally know my actual gains without exporting CSVs or paying for a separate portfolio tracker.”
James T.
Long-term ETH holder
“Most wallets feel like they were built for traders. Heldby is the first one that actually feels made for someone like me — I just want to hold safely.”
