Research Report
1. Product Vision & Overview Build a production-grade, non-custodial AI agent wallet platform on Solana that enables autonomous AI agents to securely manage digital assets, execute on-chain transactions, interact with DeFi protocols, and operate within programmable policy guardrails — all while maintaining human oversight and enterprise-grade security.
AI agents are emerging as autonomous economic participants. They need to:
Hold and manage digital assets independently
Execute transactions without constant human approval for routine operations
Interact with DeFi protocols (swap, lend, stake, provide liquidity)
Operate within strict security boundaries to prevent loss of funds
Support gasless transactions for seamless UX
Current gaps in the market:
Most wallet solutions require human signing for every transaction
No unified framework combines agent logic + wallet security + policy engine + fee relaying
Existing solutions lack enterprise-grade observability and audit trails
Cross-protocol agent interactions are fragile and not standardized
SolAgent is a full-stack platform consisting of:

8.1 Key Security Principles
Zero Trust — Every request is authenticated and authorized, internal or externalDefense in Depth — Multiple layers: TEE → Policy Engine → Rate Limiting → MonitoringLeast Privilege — Agents receive minimum permissions needed for their taskImmutable Audit Trail — Every transaction and policy decision is logged and tamper-evidentFail Secure — On any error, default to denying transactions

10. Constraints & Assumptions
Must work within Solana's 1232-byte transaction size limit
Must handle Solana's transaction expiry (blockhash TTL ~60-90 seconds)
Must comply with Solana's compute unit limits per transaction (200K default, 1.4M max)
Kora fee relayer requires operator SOL balance maintenance
TEE availability limited to specific cloud providers (AWS Nitro, Azure SGX)
Solana network maintains current performance characteristics
Helius and Kora remain operational and supported
LLM providers (OpenAI, Anthropic) maintain API stability
DeFi protocol SDKs maintain backward compatibility
Target deployment on AWS (primary) with GCP (DR)
Term
Definition
TEE Trusted Execution Environment — hardware-isolated secure enclave
MPC Multi-Party Computation — key splitting across multiple parties
SPL Token Solana Program Library token standard
ATA Associated Token Account — deterministic token account per wallet
Lamports Smallest SOL unit (1 SOL = 1,000,000,000 lamports)
Compute Units Solana's measure of transaction computational cost
MCP Model Context Protocol — standardized AI-tool interface
DAS API Digital Asset Standard API — Helius metadata API
Priority Fee Additional fee to accelerate transaction inclusion
Blockhash Recent block hash required for transaction validity
