Finality Connect

A decentralized protocol for cross-chain token licensing and verification on blockchain networks.

Overview

Finality Connect enables:

• Cross-chain token licensing
• Flexible usage rights management
• Secure token verification
• Multi-tier access control
• Transparent licensing mechanisms

Key Features:

• Decentralized licensing infrastructure
• Flexible permission models
• Interoperable token verification
• Secure transfer of usage rights
• Blockchain-agnostic design

Architecture

The protocol consists of two primary smart contracts handling core functionality:

Contract Documentation

Finality Core (finality-core.clar)

The core contract manages fundamental token functionality:

• Token creation and ownership tracking
• Transfer and verification mechanisms
• Rights management
• Metadata handling

Key features:

• Configurable royalty percentages
• Platform fee support
• Metadata immutability
• Cross-chain compatibility

Licensing (finality-licensing.clar)

Handles token licensing and usage rights:

• Flexible licensing tiers
• Configurable access levels
• License verification system
• Usage tracking and management

Getting Started

Prerequisites

• Clarinet
• Blockchain wallet
• Native tokens for transactions

Basic Usage

1. Creating a token:

(contract-call? .finality-core create-token "metadata-uri" u100)

2. Listing a token for sale:

(contract-call? .finality-core list-token token-id price)

3. Configuring a license:

(contract-call? .finality-licensing configure-license-tier token-id tier price duration-days max-licenses)

Function Reference

Core Contract Functions

Token Management

(create-token (metadata-uri (string-utf8 256)) (royalty-percentage uint))
(update-token-metadata (token-id uint) (new-metadata-uri (string-utf8 256)))
(freeze-token-metadata (token-id uint))

Trading

(list-token (token-id uint) (price uint))
(buy-token (token-id uint))
(make-offer (token-id uint) (offer-price uint) (expiry uint))
(accept-offer (token-id uint) (offerer principal))

Licensing Functions

License Management

(configure-license-tier (token-id uint) (tier uint) (price uint) (duration-days uint) (max-licenses (optional uint)))
(purchase-license (token-id uint) (tier uint))
(renew-license (token-id uint) (tier uint))
(revoke-license (token-id uint) (tier uint) (licensee principal))

Security Considerations

Core Contract

• Royalty calculations use basis points to avoid floating-point issues
• Ownership checks prevent unauthorized transfers
• Metadata freezing prevents post-sale modifications

Licensing Contract

• License validation prevents unauthorized usage
• Expiration tracking ensures proper access control
• Creator-only license configuration and revocation
• Maximum license count enforcement

General

• All financial transactions verify sufficient funds
• Access control checks on privileged operations
• State changes are atomic and consistent
