+## Context Filters
 
 Control what blockchain data informs AI responses through context filtering:
 
 ```json
 {
   "context_filter": {
-    "chain_ids": [1],              // Ethereum mainnet
-    "contract_addresses": ["0x..."] // Target contract address
+    "chain_ids": [1],              // comma delimited list of chain ID's
+    "contract_addresses": ["0x..."], // Comma delimited list of contract addresses
+    "wallet_addresses": ["0x..."] // Comma delimited list of wallet addresses
   }
 }
 ```
 
 Benefits:
 - Filter by blockchain networks using chain IDs
 - Target specific contract addresses
+- Target specific wallet addresses
 - Control context scope for relevant responses
 - Optimize token usage and response relevance
