Zero Knowledge Token Transfer

An ERC20 Token solution for private transfers
Use on Kaleido
Coming Soon

Transact confidently, knowing your transactions are private and protected by zero-knowledge proof. You can transact with network members while keeping your identity and token balances private. Apply complex technologies like zero-knowledge proof and advanced cryptography in a simple and intuitive use case of anonymous token transfers. Kaleido removes the complexity so you can focus on how to apply the technology for your use case.

Features

Innovative & Proven ZKP Technology

Zero Knowledge Token Transfer makes use of the latest technologies around zero-knowledge proofs and advanced cryptography.

Fully integrated with ERC20

Incorporate ERC20 (fungible) tokens for any use case requiring privacy and anonymity.

Anonymous Token Transfers

Transact with members of your network without disclosing the details of token amounts or parties involved.

How it works

Transfer tokens with complete privacy using the Zero Knowledge Tokens service. The service is based on the Anonymous Zether implementation by JPMC, which is an extended implementation of the Zether design jointly published by Stanford University and Visa Research.

The service supports transfer of ERC20 tokens with zero knowledge proofs, so that the transaction payload appears to be random bytes to the participants in the blockchain, except for the designated sender and receiver.

Anonymity is achieved by using a group of decoy accounts to mix together with the sender and receiver accounts, so that non-parties of the transfer can not decipher the real impacted accounts.

The design of the user experience is modeled after the "fund - transfer - withdraw" flow. A summary of how this works is as follows:

  • Any account holding a balance in a standard ERC20 token contract can move some funds into a zero knowledge smart contract, and in exchange get the corresponding amount of ZTH tokens to use for private trading.
  • Using ZTH, which now represents the account's holding in the private world, accounts can make payments with each other with complete privacy. Not only is the amount hidden from all parties apart from the sender and receiver, but the identities of the sender and receiver are obscured as well by mixing them together with "decoy" accounts.
  • At any point, the ZTH balance can be exchanged back to regular ERC20 tokens by withdrawing from the zero knowledge smart contract.
  • All the ZTH transfer transactions are managed by the zero knowledge smart contract instead of the ERC20 contract. The only transactions visible in the ERC20 contracts are the funding and withdrawing transactions.
