# 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.

## 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.
