Aura

Aura Wallet is a cross-chain stablecoin yield optimization platform that helps users earn consistent returns from 4.3% to 13%+ APY without using leverage. By connecting your existing Coinbase or Gemini wallets, Aura automatically discovers and executes the best yield strategies across multiple blockchains while keeping your funds liquid in stablecoins.

Core Value Proposition

• Stable Returns, No Leverage: Access yields starting at 4.3% baseline up to 13%+ through lending protocols, liquidity provision, and staking - all without leverage risk
• Stay Liquid: Maintain full liquidity with USDC and other stablecoins while earning competitive yields
• Connect Existing Wallets: Seamlessly integrate with your Coinbase or Gemini accounts - no need to create new wallets
• AI-Powered Strategy Discovery: Autonomous agents using Coinbase AgentKit continuously scan DeFi protocols to identify new yield opportunities
• Cross-Chain Optimization: Automatically move funds between Base, Avalanche, and other chains to capture the best risk-adjusted yields

Autonomous Agent Technology

• Coinbase AgentKit Integration: Enables AI agents to autonomously interact with blockchain protocols and discover yield opportunities
• x402 Payment Protocol: Agents use micropayments to access premium DeFi analytics and risk scoring APIs for better yield discovery
• 24/7 Opportunity Scanning: Agents never sleep - constantly monitoring protocols for new pools, rate changes, and emerging opportunities
• Self-Executing Strategies: Once opportunities are identified and verified, agents can execute rebalancing without manual intervention

Circle USDC & CCTP Integration

• Native USDC: Uses Circle's fully-reserved, regulated USDC stablecoin backed 1:1 by US dollars
• Secure Cross-Chain Transfers: Circle's CCTP (Cross-Chain Transfer Protocol) enables native USDC movement without wrapped tokens or bridge risks
• Full Transparency: Every CCTP transfer is verifiable on-chain with Circle's attestation service providing cryptographic proof
• No Bridge Risk: Unlike traditional bridges, CCTP burns USDC on the source chain and mints on destination - eliminating wrapped token vulnerabilities
• Regulatory Compliance: Circle's infrastructure ensures all transfers meet regulatory standards with complete audit trails

Key Features

• Multi-Chain Stablecoin Support: Native USDC across Base and Avalanche via CCTP, with PYUSD integration for additional yield sources
• Intelligent Rebalancing: AI agents monitor yield differentials and automatically rebalance when spreads exceed thresholds
• Risk-First Approach: All strategies are vetted for safety - no leverage, no impermanent loss risks, just sustainable yields
• Transparent Operations: Natural language chat interface explains why funds are moved and which strategies are being used

Architecture focused on Autonomous Yield Generation

We built Aura as an autonomous yield aggregation platform combining Coinbase AgentKit for blockchain interactions, x402 for premium data access, Circle's CCTP for secure transfers, and AI agents for intelligence.

Autonomous Agent Implementation (AgentKit + x402)

Coinbase AgentKit:

• Provides AI agents with native blockchain capabilities - reading contracts, checking APYs, executing transactions
• Agents can autonomously discover new lending pools, LP opportunities, and staking rewards
• Built-in safety rails ensure agents only execute pre-approved strategy types (no leverage, no risky protocols)
• Session key management allows agents to operate without accessing private keys

x402 Payment Protocol Integration:

• Agents use micropayments (fractions of cents) to access premium DeFi data
• Risk scoring APIs: Pay $0.001 per query to get protocol safety scores
• Yield analytics: Access historical APY data and volatility metrics
• Smart routing: Pay for optimal path finding across multiple protocols
• This creates a sustainable model where agents only pay for valuable data that leads to better yields

Autonomous Discovery Process:

1. AgentKit-powered agents scan all major DeFi protocols every 60 seconds
2. Use x402 to query risk scores for new opportunities (filtering out risky protocols)
3. Compare yields across chains accounting for gas costs
4. Execute rebalancing when opportunities exceed thresholds
5. All actions logged and explained via natural language

Circle USDC & CCTP Implementation

USDC as Primary Asset: Chose Circle's USDC for its regulatory compliance and full reserves

CCTP Security Benefits:

• Enhanced Security: No wrapped tokens means no bridge TVL risk
• Complete Visibility: Every transfer generates verifiable on-chain attestation
• Faster Settlement: ~15 minute finality with cryptographic proof
• Lower Risk: Eliminates bridge hacks that have caused billions in losses

Technical CCTP Flow with AgentKit:

1. Agent identifies yield opportunity on different chain
2. AgentKit initiates CCTP burn transaction on source chain
3. Circle's attestation service witnesses and signs the burn
4. Agent retrieves attestation and completes mint on destination
5. Funds deployed to higher-yielding protocol automatically

Yield Discovery Engine Architecture

• GraphAPI (deprecated but still remnants for future dev - ASI Fetch.ai Agents: Core intelligence layer for strategy evaluation)
• AgentKit Integration: Enables agents to execute discovered strategies on-chain
• x402 Data Layer: Access to premium analytics for better decision making
• Strategy Filters: Only non-leveraged positions yielding 4.3%+ considered
• Risk Scoring Pipeline:
  • Query protocol TVL and age via AgentKit
  • Pay for detailed risk analysis via x402
  • Cross-reference with on-chain data
  • Only proceed if risk score meets thresholds

Technical Implementation Highlights

1. AgentKit Autonomous Operations:

• Agents granted limited session keys for specific operations
• Can read all DeFi protocols and check yields
• Can execute pre-approved transaction types (deposits, withdrawals, CCTP transfers)
• Cannot access user private keys or execute unauthorized operations

2. x402 Micropayment Efficiency:

• Average cost: $0.05-0.10 per day for continuous monitoring
• ROI: 0.001% cost for discovering 2-5% yield improvements
• Payment channels ensure no gas overhead for micropayments
• Agents optimize query patterns to minimize costs

3. Multi-Layer Security:

• AgentKit: Session keys with limited permissions
• CCTP: No bridge risk with burn-and-mint
• x402: Pay only for verified data sources
• Smart contracts: Time-locked operations for safety

Partner Technology Benefits

• Coinbase AgentKit: Enables true autonomous blockchain operations without compromising security
• x402 Protocol: Access to premium DeFi data and risk analytics on a pay-per-use basis
• Circle (USDC & CCTP): Secure, transparent, regulatory-compliant infrastructure for cross-chain operations
• ASI Agents: 24/7 intelligent monitoring and decision making
• Coinbase/Gemini Wallets: Trusted custody while Aura handles optimization

The system achieves true autonomy - agents discover opportunities via AgentKit, verify them with x402 data, execute via CCTP, all while maintaining complete security and transparency. Users simply connect their wallets and watch their stablecoin yields grow from 4.3% to 13%+ automatically.
