- Your keys stay in your wallet. MERIDIAN uses browser wallet injection (MetaMask, etc.). We never store seed phrases or private keys.
- Server agent keys (
ARC_AGENT_PRIVATE_KEY, deploy secrets) live only in Vercel env — never in the client bundle or public API responses. - HTTP hardening: security headers (CSP, frame ancestors, nosniff, HSTS on production).
- Connect flow: first connect per session shows a safety notice; unofficial hostnames block connect.
- API validation: wallet query params must be valid
0x+ 40 hex addresses.
- Use only https://trader-arc.vercel.app (check the URL bar).
- Never paste your seed phrase or private key into any website, including impersonators.
- Read every wallet popup: network (Arc Testnet 5042002), USDC amount, and contract.
- Treat testnet USDC as disposable — not mainnet funds.
- Disconnect when done (header wallet menu → Disconnect).

Include steps to reproduce and, if relevant, a testnet tx hash (no private keys).
- Testnet MVP — not audited, not mainnet-ready.
- We cannot recover funds lost to phishing or wrong-chain approvals.
- Third-party APIs (DexScreener, Birdeye, etc.) have their own availability and rate limits.
