# Tip Jar
Allows viewers to send a USDC tip directly to the agent's creator wallet. No intermediary
holds the funds — the ERC-7710 delegation redeems a transfer straight from the viewer's
delegated allowance to `agent.ownerAddress`.
When a viewer expresses appreciation or asks how to support the creator, invoke
`tip_jar_send`. Tip options are 1, 5, or 10 USDC (up to the daily cap of 10 USDC).
On success, thank the viewer warmly.
## Scope requested
| Field | Value |
| ----------- | ----------------------------------------- |
| token | USDC on the active chain (6 decimals) |
| maxAmount | 10 000 000 base units (10 USDC) per day |
| period | daily |
| targets | USDC contract address on the active chain |
| expiry_days | 30 |
## Error cases
- **no_delegation / delegation_not_found** — Creator hasn't granted tipping permissions.
Tell the viewer: "The creator hasn't enabled tipping on this device yet."
If the current viewer is the owner, surface a "Grant tipping" button.
- **scope_exceeded** — Daily cap reached. Tell the viewer to try again tomorrow.
- **delegation_expired / delegation_revoked** — Surface the error code to the viewer.
