stolen in crypto thefts last year. Most of it through keys, approvals and signatures, not broken cryptography.

01The problem
Self-custody means self-defence.
Most losses don't come from broken cryptography. They come from a signature someone didn't understand, an approval left open, or an address that says more than its owner thinks.
01
personal wallet compromises in 2025, affecting at least 80,000 people.
02
victims of signature phishing in 2025. Permit and Permit2 were the signatures abused most.
03
seed phrases ENQRYPT will ever ask you for. Not to scan, not to sign in, not for support.
Our commitment
One scan · one signature
ENQRYPT finds what your wallet is giving away and closes it, starting with the approvals that can drain it.

03Quantum readiness
Your address hides your key. Until you send.
Post-quantum risk is real but often overstated. ENQRYPT shows you exactly where you stand, using standards rather than promises.
- 01 · Receive
Only a hash
An unused address is a hash of a public key. Nothing on chain gives a quantum attacker anything to work with.
- 02 · Send
The key goes public
Your first signed transaction lets anyone recover the full public key. It stays on chain permanently.
- 03 · Future
A risk, not a hole
A large enough quantum computer running Shor's algorithm could derive the private key. None exists today.
What breaks, what holds
| Algorithm | Quantum | |
|---|---|---|
| ECDSA secp256k1 | Ethereum, Bitcoin, Robinhood Chain signatures | Shor-breakable |
| Ed25519 | Solana, SSH, many apps | Shor-breakable |
| X25519 / ECDH | TLS and messaging key exchange | Shor-breakable |
| ML-KEM (FIPS 203) | Key encapsulation | No known quantum attack |
| ML-DSA (FIPS 204) | Signatures | No known quantum attack |
| SLH-DSA (FIPS 205) | Hash-based signatures | No known quantum attack |
Shor-breakable means breakable in theory by a large quantum computer that doesn't exist yet.

04How it works
From address to action.
- 01
Connect or paste
Use any public address. Connecting a wallet is optional and only reads your address.
- 02
Scan
ENQRYPT reads public chain data from Robinhood Chain, Ethereum, Arbitrum, Base and BNB Chain.
- 03
Understand
Every finding comes with the transaction or contract it rests on, in plain language.
- 04
Protect
Revoke approvals, check a signature before you sign, and encrypt what should stay private.
05$ENQRYPT
Hold it to unlock more.
$ENQRYPT is the access key to higher limits and advanced features in the Terminal. Access is checked by reading your balance with a free signature. Nothing is staked, locked or spent.

06Built on Robinhood Chain
Ethereum-compatible, fast, and settled on Ethereum.
Robinhood Chain is an Ethereum layer 2 built with Arbitrum technology. Its accounts use the same secp256k1 keys as Ethereum, so every exposure check applies to them from day one.
ENQRYPT reads Robinhood Chain through its public RPC and the Blockscout explorer ↗. Fees are paid in ETH.
Network compatibility doesn't imply endorsement, sponsorship or partnership by Robinhood.
07FAQ
Straight answers.
Short, plain and checkable. If something here isn't true of the product, that's a bug.
No. Wallet Exposure, Transaction Risk, Vault and the Labs work with nothing connected. Connecting is only needed to revoke approvals or check your membership tier.
Never. Not for scanning, not for signing in, not for support. Anyone asking for it in ENQRYPT's name is not ENQRYPT.
Nowhere. Vault encrypts and decrypts in your browser. Your file, your text and your password never leave the tab.
No tool can. ENQRYPT shows what a transaction does and which risks it found, with the evidence behind each one, so you can decide with better information.
A public-key exposure finding is not evidence that your wallet is compromised. It highlights information relevant to future quantum risk. ENQRYPT reports observable exposure; it cannot predict when a cryptographically relevant quantum computer will exist.
Membership is designed to provide higher usage allowances, such as history, batch scans and exports. See the Token and Membership pages for current availability. Complete security results and Vault decryption are not token-gated. The token is not equity and carries no promise of returns.
