EmitKey is a minimalistic tool for creating and remembering secure codes.
Instead of writing down passwords or codes, EmitKey allows you to generate a unique code from a token transaction.
This way, your code is securely anchored to the blockchain - always retrievable from your transaction history.

Use the transaction data as your code anchor
🧠 You don't store or memorize a code - you derive it from the transaction whenever you need it.
Your EmitKey Core token transaction on basescan.org holds everything:
- • The transaction hash (e.g. use the last 10 digits)
- • The block number
- • The timestamp
These elements are immutable and unique, and always available on-chain.
You send a file to a friend but don't share the password directly.
Instead, you tell them:
"Use the last 10 characters of the EmitKey Core transaction hash from 2025-07-09.
Check wallet 0xCAF...D959 on BaseScan."
💡 This way, the code exists - but only for those who know how to find it.
EmitKey uses EmitKey Core tokens (fungible) instead of NFTs.
Why? Because:
Yes, technically you can use any transaction hash on any chain.
However, the EmitKey Core token was specifically created for this purpose - its name serves as a mental reminder, and the Token Lookup Tool on this website only works with EmitKey Core.
So while the method is universal, EmitKey offers the cleanest and most integrated experience.
To help meet password requirements (like uppercase and special characters), we automatically add Emky at the beginning and ! at the end.
➡️ Example:
A code like 74h84451a0 becomes: Emky74h84451a0!
You can, of course, add your own variations or extra characters - just make sure you remember them.
EmitKey does not store any private data.
The system uses public blockchain data only - the code is never stored, only derived.
Simple
Easy to use
Private
No data stored
Resilient
Always available
🔐 Securely Sharing Credentials
Share server or system login credentials by transmitting the EmitKey code through one secure channel, while communicating the derivation method through another channel.
🏢 One-Time Passwords for Internal Use
Companies can generate temporary access codes for specific resources, designed to become invalid after a certain transaction or event occurs.
📜 Accessing Digital Legacies
For digital estate planning, securely store instructions and derivation paths for EmitKey codes that grant access to important digital accounts or encrypted files.
📋 Contract and Document Validation
Embed EmitKey codes within documents, tied to specific transactions, to validate integrity or timing of creation alongside electronic signatures.
💌 Encrypted Messages for Special Occasions
Encrypt secret messages or well wishes that can only be unlocked if the recipient can derive the specific EmitKey code tied to a particular blockchain transaction.
It is crucial that you remember the exact method you used to derive your code.
EmitKey doesn't store any private data. If you forget how you derived your code (e.g. which part of the transaction you used), there is no way to recover it.
Think of EmitKey as a unique key you forge yourself - if you forget how you forged it, no one can reproduce it for you.
💡 Always document your derivation method clearly, like: "Use the last 10 characters of the transaction hash from July 9, 2025 - transaction X from wallet Y."
Yes, technically any transaction hash on any blockchain can be used.
But EmitKey Core Tokens are optimized for this use - and only they work with the Token Lookup Tool.
EmitKey is not a replacement for traditional password managers - it's a complementary tool designed for different use cases.
Traditional Password Managers
- • Store encrypted passwords centrally
- • Require trust in the service provider
- • Single point of failure
- • Subscription-based services
EmitKey
- • Never stores any codes or passwords
- • Completely decentralized
- • No central point of failure
- • Tied to immutable blockchain data
💡 EmitKey eliminates the risk of centralized data storage and is ideal for scenarios where you need a decentralized, non-custodial method for code creation and recovery.
