I provide a focused, reproducible security and integration package for Solana/Web3 products, agents, games and APIs. I review wallet and transaction flows, token/payment logic, authorization boundaries, replay/nonce handling, webhook and RPC assumptions, and smart-contract/API interaction risks.
Deliverables are agreed up front and can include:
• architecture and threat model;
• read-only or devnet-first proof of concept;
• OpenAPI 3.x documentation and endpoint examples;
• local regression tests with exact reproduction steps;
• prioritized findings with remediation guidance; and
• a concise deployment/runbook handoff.
I use Solana RPC/SPL and can keep the design chain-agnostic when an EVM boundary is required. I do not custody client keys, bypass access controls, or test live funds without explicit written authorization. Paid work is milestone-based with escrow funded before implementation.
Public portfolio:

https://github.com/xordanx/zeroclaw-solana-payout-guardian
Available now for a fixed-scope review, integration plan, or security handoff. Typical engagements: 500–1,500 USDC, with smaller 200–400 USDC API documentation/test-plan packages available on request.
