Utility Tools
Memo transactions for on-chain interactions.
Sigil agents have access to utility tools for writing on-chain memos.
On-Chain Memo
| Tool | Description |
|---|---|
send_memo | Write a human-readable message on-chain (max 566 bytes, subject to guardrails) |
The memo tool uses the SPL Memo program to record text messages on the blockchain. This is useful for:
- Tagging transactions with notes or references
- Recording agent decisions or reasoning on-chain
- Creating an immutable audit trail
- Adding context to automated operations
Example Scenarios
"Record a memo saying 'Daily rebalance complete' on-chain"
"Write a memo with my reasoning for this trade"Use Cases

Agents can create transparent audit trails by writing memos before or after significant actions:
1. Prepare to sell
2. Send memo: "Executing rebalance: Target allocation hit"
3. Execute swap
4. Send memo: "Rebalance complete"Guardrail Integration
