Solfunmeme Dioxus Plugin Security Policy

Threat Model

Each plugin runs as WASM in the browser. Risks:

1. Data exfiltration — plugin reads wallet keys or token balances
2. UI spoofing — plugin renders fake wallet connect dialogs
3. Resource exhaustion — plugin consumes CPU/memory, freezes browser
4. Network abuse — plugin makes unauthorized RPC calls

Security Boundaries

Tier 1: DAO (🏛️) — HIGH trust

Plugins that handle governance votes and token data.

• Allowed: Read wallet pubkey, read token balances, POST to /solfunmeme/paste
• Denied: Private key access, arbitrary network, localStorage write
• Constraint: max_render_ms = 500, max_fetch = 10/min

Tier 2: Data (📊) — MEDIUM trust

Plugins that display/submit data.

• Allowed: Read-only RPC, POST to pastebin, read erdfa types
• Denied: Wallet signing, private key access, WebSocket
• Constraint: max_render_ms = 1000, max_fetch = 30/min

Tier 3: Analysis (🔬) — MEDIUM trust

Plugins that parse/analyze code.

• Allowed: CPU computation, read source files, render charts
• Denied: Network access, wallet access, storage write
• Constraint: max_render_ms = 2000 (heavy computation allowed)

Tier 4: Meta (🧬) — LOW trust

Experimental ontology/MCP modules.

• Allowed: Pure computation, render UI
• Denied: All network, all storage, all wallet
• Constraint: max_render_ms = 5000

Tier 5: Test (🧪) — SANDBOXED

Test harnesses, no production access.

• Allowed: Render only
• Denied: Everything else
• Constraint: max_render_ms = 10000

Verification

Each plugin must provide:

1. Source hash — SHA256 of source code at build time
2. zkperf witness — proves render time ≤ max_render_ms
3. Capability declaration — what APIs it claims to use
4. Audit trail — git commit + reviewer signature

Enforcement

• inventory collects plugin metadata at compile time
• Runtime: measure actual render time, compare to max_render_ms
• Violation → plugin disabled + alert to DAO senate
• Quarterly audit: all plugins re-verified against source hash

Plugin Capability Matrix

Plugin	Network	Wallet	Storage	Compute	Max ms

monster_meme	—	—	—	med	5000
mcp	—	—	—	med	5000

Incident Response

1. Plugin exceeds constraint → auto-disable, log to journal
2. Senate votes to re-enable or permanently remove
3. Source audit required before re-enable
4. All incidents posted to pastebin for transparency
