Off-chain private tokens

An implementation of off-chain private tokens in Oasis Sapphire.

Requirements:

  • Node
  • Docker

Setup

First, install all required packages with npm:

npm install

Create a dev network:

docker run -it -p8545:8545 -p8546:8546 ghcr.io/oasisprotocol/sapphire-dev -to "0x72A6CF1837105827077250171974056B40377488"

Run test cases

npx hardhat test --network dev

Fund two addresses whose private keys are in PRIVATE_KEY and PRIVATE_KEY2.

Test the deployment of the off-chain hash machine on the public Sapphire testnet:

PRIVATE_KEY=<funded private key> npx hardhat run scripts/deploy.ts --network sapphire_testnet

Run the veiled token demo on the public testnet:

PRIVATE_KEY=$PRIVATE_KEY PRIVATE_KEY2=$PRIVATE_KEY2 npx hardhat run scripts/runVeiledToken.ts --network sapphire_testnet
