Pasifika Token (PASI)

ERC-20 Token for Pacific Islander Remittances

Overview

Pasifika Token (PASI) is an ERC-20 utility token designed specifically for Pacific Islander communities and their diaspora. PASI runs natively on the Pasifika Data Chain (Chain ID: 999888) for zero-gas community transfers and is mirrored on Arbitrum One (Chain ID: 42161) to provide public DEX liquidity and global accessibility.

• Low cost remittances - Only 0.5% fee vs 5-15% traditional services
• Community governance - Role based access control with validator organizations
• Financial inclusion - Simple token transfers without traditional banking barriers
• Public market access - PASI/USDC pool live on Arbitrum Uniswap v2
• Global cross border portability - Works across US, New Zealand, Australia, Pacific Islands, EU, Russia, Asia, Africa, Arctic, Antarctica, and Middle East

Features

Core Functionality

• Standard ERC-20 transfers and approvals
• Remittance tracking with corridor identification (e.g., "US-TONGA", "NZ-SAMOA")
• Batch transfers for community distributions (up to 100 recipients)
• Burnable tokens for supply management
• Fee collection - 0.5% fee on remittances sent to Treasury

Treasury & Governance

• PasifikaTreasury contract - Collects fees from remittances
• Validator voting - Validators propose and vote on fee distributions
• Role based access control using OpenZeppelin AccessControl
• Validator management - Add/remove trusted community organizations
• Pausable - Emergency stop functionality for security
