Submit transactions anonymously and mask your true identity by leveraging an unlimited repository of one-time use addresses generated through a fully-controlled hierarchically deterministic (HD) wallet
The ID masking HD wallet offers immense benefits for anonymity via the ability to leverage a random unused “identity” for each externally signed transaction

Unlimited, Unique Accounts & Associated Private Keys

Mask your identity on a per-transaction basis via an unlimited supply of account addresses, each with their own unique, untraceable private key
Different accounts can be used for different transaction classes or to manage the end users of an organization

Easily backup and restore an exact replica of your wallet when you need it
Using a 12-word mnemonic "seed phrase” (entropy), each account can be recreated identically
Remember the mnemonic, never lose the wallet

Multiple Wallets for Account ID Management

Partition separate wallets across your organization to avoid key reuse and duplicate signing

An abbreviation for hierarchical determinism, the Kaleido HD Wallet is a key tree that provides a deterministic derivation of Ethereum account addresses and their corresponding private signing keys from a single seed phrase
The overall HD wallet implementation is a byproduct of several Bitcoin Improvement Proposals (BIP), specifically BIP32 for the core cryptography and key generation, BIP39 for seed phrase and recovery, and BIP44 for multi-protocol account hierarchy

The seed phrase, a 12 word mnemonic, can be generated in one of two ways: either by the service via the BIP39 spec or submitted manually by the user as an “easy to remember hard to guess” expression
The seed phrase serves as the master root for the entire key tree, therefore strong entropy should be applied if manual submission is the desired course of action

HD wallets provide an elegant solution for both account management and identity masking, as the key tree can be deterministically regenerated from the master seed phrase and users can increment their account index on a per-transaction basis to anonymize identity via unique signing keys

Common Questions about HD Wallets

What are HD Wallets?

HD wallets, or Hierarchical Deterministic wallets, are a type of blockchain wallet that use a single master seed to generate an entire tree of private keys
HD wallets have the advantage of being able to generate a virtually unlimited number of private keys, so the user can have a unique address for every transaction if they wish, enhancing privacy and security

How do HD Wallets work?

HD wallets work by generating a single master seed when the wallet is first created
This master seed is a string of randomly generated words that is used to generate all of the private keys for the wallet
When a user wants to make a transaction, the HD wallet uses the master seed to generate a unique private key for that specific transaction
The private key is then used to create a digital signature for the transaction, which is required to complete the transaction and transfer the funds

The advantage of using an HD wallet is that it allows the user to recover their wallet and access their funds in the event that they lose their device or forget their private keys
This is because the master seed can be used to regenerate all of the private keys for the wallet
It is important to keep the master seed in a secure location because anyone who has access to the master seed will also be able to access the funds in the wallet

What are the benefits of HD Wallets?

There are several benefits to HD wallets, including

• Security: HD wallets offer enhanced security because they use a single master seed to generate all of the private keys for the wallet
• This means that the wallet can be recovered from a single seed in the event that the wallet is lost or the user forgets their private keys
• Convenience: HD wallets allow users to generate a virtually unlimited number of private keys, which means they can have a unique address for every transaction if they wish
• This can be convenient for users who want to maintain privacy or who want to keep their transactions separate from each other
• Compatibility: HD wallets are compatible with a wide range of devices, including desktop computers, mobile phones, and hardware wallets
• This means that users have the flexibility to access their HD wallet from any device they choose
• Ease of use: HD wallets are easy to use and do not require the user to remember multiple private keys
• Instead, the user only needs to remember the single master seed in order to access their wallet and complete transactions
• Overall, HD wallets offer a convenient and secure way to manage and store digital assets, which is why they are widely used in blockchain apps
