13 Smart Contract Overview

PSAI Token Contract Architecture

ProSignal AI's blockchain infrastructure centers around the PSAI token, a custom ERC-20 smart contract deployed on the Base network. The contract is designed with specific features to support the platform's tokenomics while maintaining security and regulatory compliance.

Token Specifications

Core Parameters

• Token Name: ProSignal AI

• Symbol: PSAI

• Standard: ERC-20 (OpenZeppelin implementation)

• Network: Base (Ethereum Layer 2)

• Chain ID: 8453

• Total Supply: 1,000,000,000 PSAI (fixed supply)

• Decimals: 18 (standard ERC-20 precision)

Contract Features

Standard ERC-20 Functionality

• Transfer and approval mechanisms

• Balance tracking and allowance management

• Standard events for transparency

• Full compatibility with existing DeFi infrastructure

Airdrop Distribution System

• Owner-controlled token distribution for airdrop campaigns

• Automatic transfer lock application for airdrop recipients

• Transparent claiming process with event emission

• Protection against unauthorized token distribution

Transfer Lock Mechanism

• Selective transfer restrictions for airdrop recipients only

• Global unlock capability after Token Generation Event (TGE)

• Normal purchasers and holders maintain full transfer rights

• Owner cannot re-lock transfers once globally enabled

Security Architecture

Access Control

The PSAI contract implements OpenZeppelin's Ownable pattern with specific limitations.

Owner Capabilities

• Distribute airdrop tokens to eligible participants

• Enable global transfers after TGE period (typically 24 hours)

• Cannot mint additional tokens beyond the initial supply

• Cannot freeze normal user transfers

• Cannot re-lock transfers once globally enabled

User Protections

• Only airdrop recipients face temporary transfer restrictions

• Normal token purchasers have immediate transfer rights

• The owner cannot arbitrarily lock user funds

• Transfer restrictions are time-limited and transparent

All owner administrative functions are constrained to ensure the owner cannot mint tokens or arbitrarily re-lock transfers once global transfers are enabled.

Anti-Abuse Mechanisms

Airdrop Protection

• Prevents immediate dumping of airdrop tokens

• Allows the platform to establish initial liquidity

• Protects early supporters from excessive selling pressure

• Maintains token price stability during the launch phase

Transparency Features

• All airdrop distributions emit public events

• Transfer lock status is publicly queryable

• Global transfer status is visible on-chain

• Complete audit trail of all token movements

Technical Implementation

Smart Contract Functions

Core ERC-20 Operations

• transfer(): Standard token transfers with lock checking

• approve(): Standard allowance approval

• balanceOf(): Query token balance

• totalSupply(): Query total token supply

Airdrop Management

• claimAirdrop(): Owner-only function to distribute tokens

• enableTransfers(): Owner-only function to unlock transfers

• canTransfer(): Public function to check transfer eligibility

• hasTransferLock: Public mapping to check lock status

Security Validations

• Address validation for all operations

• Amount validation for token distributions

• Transfer lock enforcement for restricted addresses

• Owner permission checks for administrative functions

Event Logging

Transparency Events

PSAIEvents.sol

event TransfersEnabled(uint256 timestamp);
event TransferLockSet(address indexed account, bool locked);
event AirdropClaimed(address indexed user, uint256 amount);

These events provide complete transparency for:

• When global transfers are enabled

• Which addresses receive transfer locks

• All airdrop token distributions

• Timing of all administrative actions

Deployment Strategy

Base Network Advantages

Cost Efficiency

• Significantly lower gas fees compared to the Ethereum mainnet

• Faster transaction confirmation times

• Better user experience for frequent interactions

• Reduced barriers to entry for new users

Technical Benefits

• Full Ethereum Virtual Machine (EVM) compatibility

• Seamless integration with existing Web3 tools

• Strong security backed by the Ethereum mainnet

• Growing ecosystem of DeFi applications

Strategic Positioning

• Access to Coinbase's user base and infrastructure

• Alignment with major institutional adoption

• Future integration opportunities with Coinbase products

• Regulatory clarity through established partnerships

Contract Verification

Security Measures

• Open-source contract code for community verification

• Standard OpenZeppelin libraries for proven security

• Comprehensive testing before mainnet deployment

• Professional audit considerations for future versions

Transparency Standards

• Public contract address and source code

• Verified contract on Base network explorer

• Complete documentation of all functions

• Clear explanation of all contract features

Token Distribution Mechanism

Airdrop Implementation

Distribution Process

1

Eligibility Verification

Backend systems verify user qualification.

2

Token Allocation

Owner calls claimAirdrop() with user address and amount.

3

Automatic Lock

Transfer lock automatically applied to recipient.

4

Event Emission

Public record of distribution created.

5

User Notification

Platform notifies user of successful claim.

Lock Management

• Transfer locks only affect airdrop recipients

• Normal token purchasers have immediate transfer rights

• Global unlock occurs after predetermined period

• Emergency unlock capability for critical situations

Treasury Management

Token Custody

• Contract owner holds initial token supply

• Controlled distribution prevents unauthorized access

• Multi-signature wallet recommended for production

• Clear separation between operational and treasury functions

Distribution Tracking

• On-chain record of all token distributions

• Real-time visibility into remaining treasury balance

• Transparent allocation across different programs

• Audit trail for compliance and reporting

Future Contract Enhancements

Planned Upgrades

Staking Integration

• Smart contract-based staking mechanisms

• Automated reward distribution systems

• Lock-up periods for enhanced rewards

• Integration with platform revenue sharing

Governance Implementation

• On-chain voting mechanisms for platform decisions

• Proposal submission and voting systems

• Time-locked execution for approved proposals

• Delegation mechanisms for governance participation

Advanced Features

• Cross-chain bridge compatibility

• Integration with DeFi protocols

• Advanced tokenomics mechanisms

• Enhanced security features

Scalability Considerations

Performance Optimization

• Gas-efficient contract design

• Batch operations for large distributions

• Optimized storage patterns

• Minimal on-chain computation requirements

Integration Capabilities

• Standard ERC-20 interface for universal compatibility

• Integration with major DEX platforms

• Wallet compatibility across all major providers

• API integration for platform features

The PSAI smart contract represents a carefully designed foundation for the ProSignal AI ecosystem, balancing security, functionality, and user experience while providing the flexibility needed for future platform growth and enhancement.
