wallet-agent Tools (L2 Forensics)
Use these instead of raw RPC chaining:
getAssetsByOwner — deployer wallet holdings
POST https://mainnet.helius-rpc.com/?api-key=${HELIUS_API_KEY} { "jsonrpc": "2.0", "id": "1", "method": "getAssetsByOwner", "params": { "ownerAddress": "", "page": 1, "limit": 20, "displayOptions": { "showFungible": true } } } → Returns: full token holdings with metadata
getTransactionsForAddress — deployer tx history
POST https://mainnet.helius-rpc.com/?api-key=${HELIUS_API_KEY} { "jsonrpc": "2.0", "id": "1", "method": "getTransactionsForAddress", "params": { "address": "", "limit": 50 } } → Returns: parsed tx history, rug patterns, previous deploys → NOTE: Requires Developer plan. If 403, fall back to getSignaturesForAddress.
safety-agent Tools (L2 Authority Check)
getAsset — mint/freeze authority status
POST https://mainnet.helius-rpc.com/?api-key=${HELIUS_API_KEY} { "jsonrpc": "2.0", "id": "1", "method": "getAsset", "params": { "id": "" } } → Check: authorities.mint (should be null), authorities.freeze (should be null) → Scoring: null mint + null freeze = +5 bonus. Active = instant kill.
Scoring Impact
- Mint authority revoked + freeze revoked → +5 (confirmed via getAsset)
- Deployer wallet clean (no prev rugs) → supports TEAM TOKEN +10
- LP UNVERIFIED penalty (-15) reduced with getAssetsByOwner confirmation
Rate Limits (Free tier)
- RPC: 10 req/s | DAS: 2 req/s | Credits: 1M/month
- getAsset: 10 credits | getAssetsByOwner: 10 credits
- getTransactionsForAddress: 100 credits (Developer+ only)
