Consumable

Introduction

Consumables are a new way to interact with Smart Contracts. They enable the creation of on-chain one-time secrets that are resistant to front-running and can be consumed against any EVM function, in a secure and privacy-enhancing manner.

Motivation

Protecting smart contract function executions with secure passwords unlocks many different and new use cases, like linking secrets to physical products for claiming originality certificates (NFTS) , giving away vouchers for expending tokens, and even anonymous voting.

The use of cryptographic secure passwords to protect smart contract function executions unlocks various new use cases, including:

• Linking one-time claiming secrets to physical products via QR's for originality certificates (NFTs).
• Distributing vouchers for one-time payments.
• Enabling anonymous voting mechanisms by delivering one-time voting vouchers.

Consumable SDK

https://www.npmjs.com/package/consumable-sdk

The Consumable SDK is an open-source toolkit that can be installed via npm. It provides utilities to generate and manage secrets for Consumable-compatible smart contracts.

Installation:

npm install -g consumable-sdk

CLI Commands:

• Generate Wallets:

  generateWallets <amount> [outputDir]

• Generate Secrets:

  generateSecrets <inputDir> <chainId> <contractAddress> <methodSignature>

• Fund Wallets:

  fundWallets <dumpFilename> <funderPrivateKey> <chainId> <rpcUrl> <amount>
