what's Seraphina?

Seraphina is a fully autonomous Solana memecoin trading agent that operates 24/7 on a 5-minute scan cycle. Powered by Claude Opus 4.6 for decision-making, it leverages Bitget Wallet Skill for on-chain data acquisition (prices, K-lines, liquidity, security audits) and trade execution. The agent evaluates candidates using a multi-signal scoring system (momentum, volume, smart money, community boost, etc., out of 100; threshold 60), with hard rejects for honeypots/buy-disabled tokens and penalties for other risks. Persistent memory via Mem0 enables learning from past trades across isolated sessions, while fallback modes ensure resilience to data failures.[[2]](https://github.com/tzenn/Seraphina)[[1]](https://x.com/i/status/2035192135197368494) Built on the OpenClaw framework, Seraphina includes robust risk management: 10% position sizing, stop-loss at -40%, partial take-profit at +30% (sell half) and full at +300%, plus 12-hour time-based exit. A 15-minute heartbeat provides emergency monitoring. Open-sourced as a complete OpenClaw workspace for the Solana Agent Economy Hackathon, it represents an AI-driven protocol for automated memecoin trading with deterministic, scalable architecture.[[2]](https://github.com/tzenn/Seraphina)
