​
Hybrid Decentralization Model

Gasyard operates as a hybrid protocol - core infrastructure partially centralized for optimal performance, with user funds fully secured on-chain. We’re moving toward full decentralization over time.

Centralized (Today)

Intent processing and solver coordination for optimal performance and user experience

Decentralized (Today)

Fund custody, settlement, and transaction execution secured by smart contracts

Future (2024-2025)

Fully trustless intent-solver network with protocol-managed risk and rebalancing

​
Smart Contract Security

​
Non-Upgradeable Architecture

Immutable Code ProtectionCore vault and gateway contracts are non-upgradeable, preventing any single party from modifying fund custody logic or payment settlement mechanisms.
Security Properties:
  • Immutable vault contracts prevent unauthorized fund access
  • Multisig ownership eliminates single points of failure
  • Time-locked operations provide protection windows
  • Emergency pause mechanisms enable rapid incident response

​
Contract Audit & Verification

Professional Audits

Smart contracts audited by leading security firms with public reports available

Formal Verification

Critical functions mathematically proven secure using formal verification methods
Audit Status:
  • Vault Contracts: Audit in progress (Q1 2024)
  • Gateway Contracts: Security review scheduled
  • Intent Processing: Formal verification completed
  • Cross-Chain Logic: Audit scheduled Q2 2024

​
User Fund Protection

​
100% Reserve Backing

Fund Safety Guarantee

Every dollar in user vault balance is backed by real USDC reserves and can be redeemed 1:1 regardless of protocol status or solver performance.
Reserve Management: 
{
  "totalUserDeposits": "$127.8M",
  "usdcReserves": "$134.2M",
  "reserveRatio": "105.0%",
  "status": "HEALTHY",
  "lastRebalanceTime": "2024-01-15T14:30:00Z",
  "emergencyReserves": "$15.7M"
}

​
Base Chain Settlement

Why Base Chain for Security:

​
Withdrawal Protection

1

Daily Limits

Maximum 20% of total vault balance can be withdrawn in any 2-hour period
2

Anomaly Detection

AI-powered monitoring detects unusual withdrawal patterns automatically
3

Emergency Pause

Protocol can halt all operations within 30 seconds if compromise detected
4

Recovery Window

2-hour minimum delay for large operations provides time for incident response

​
Solver Network Security

​
Professional Liquidity Providers

Whitelisted Solver Network

Curated professional liquidity providers undergo KYC, provide collateral, and maintain high-performance standards to participate in the network.
Solver Requirements:
  • Identity Verification: Full KYC/AML compliance for all solvers
  • Collateral Posting: 200%+ collateral requirement for network participation
  • Performance Bonds: Additional bonds for high-volume operations
  • Technical Standards: Minimum uptime and latency requirements

​
Risk Management

Contract Custody

Solver funds held in smart contracts with automated slashing for failures

Transaction Limits

Maximum amounts per solver per transaction with dynamic risk adjustment
Solver Security Measures: 
✅ Maximum $100K per transaction per solver
✅ 24-hour volume limits per solver ($1M default)
✅ Reputation-based allocation (higher rep = higher limits)
✅ Automatic penalties for failed executions
✅ Instant solver suspension for malicious activity

​
Collateral & Slashing

​
Intent & Payment Security

​
Cryptographic Protection

EIP-712 Signatures

Industry-standard cryptographic signatures prevent tampering and ensure authenticity

Nonce-Based Revocation

Global nonce system enables instant invalidation of all user intents
Signature Security: 
const domain = {
  name: 'Gasyard',
  version: '1',
  chainId: 8453, // Base
  verifyingContract: '0x6a2A5B7D0434CC5b77e304bc9D68C20Dee805152'
};

const types = {
  PaymentIntent: [
    { name: 'user', type: 'address' },
    { name: 'amount', type: 'uint256' },
    { name: 'nonce', type: 'uint256' },
    { name: 'validUntil', type: 'uint256' },
    { name: 'restrictions', type: 'bytes32' }
  ]
};

​
Built-in Spending Controls

Amount Limits

Per-transaction and total spending limits prevent unauthorized large payments

Time Restrictions

Expiration dates and time windows limit exposure periods

Geographic Controls

Location-based restrictions prevent usage outside approved areas

​
Settlement Security

1

Intent Validation

Cryptographic signature verification and spending limit checks
2

Balance Verification

Real-time vault balance confirmation before execution
3

On-Chain Settlement

All payments finalized on Base chain with immutable records
4

Multi-Party Confirmation

User, recipient, and solver all receive settlement confirmations

​
System Architecture Security

​
Multi-Layer Defense

Network Layer

DDoS protection, rate limiting, and geographic distribution prevent service disruptions

Application Layer

Input validation, authentication, and authorization protect against common attacks

Database Layer

Encrypted storage, access controls, and audit logging secure sensitive data

Blockchain Layer

Smart contract security, consensus mechanisms, and cryptographic proofs

​
Monitoring & Incident Response

​
Compliance & Auditing

Regulatory Compliance

KYC/AML compliance for solvers, transaction monitoring, and regulatory reporting as required

Audit Trail

Comprehensive logging of all operations with immutable blockchain records for transparency

​
Future Decentralization Roadmap

​
Phase 1: Current State (2024)

  • ✅ User funds fully secured on-chain
  • ✅ Professional solver network operational
  • ✅ Intent processing optimized for performance
  • 🔄 Smart contract audits in progress

​
Phase 2: Partial Decentralization (Q2-Q3 2024)

  • 🔜 Solver dispute resolution on-chain
  • 🔜 Automated solver selection algorithms
  • 🔜 Community governance for key parameters
  • 🔜 Open solver network with stake requirements

​
Phase 3: Full Decentralization (Q4 2024 - Q1 2025)

  • 🔜 Trustless intent-solver matching
  • 🔜 Decentralized governance for protocol upgrades
  • 🔜 Community-managed risk parameters
  • 🔜 Fully autonomous operation
Security First ApproachWe prioritize security over speed of decentralization. Each phase includes extensive testing, auditing, and gradual rollout to ensure user fund safety.
