Configuration
| Variable | Required | Secret | Description |

The Swarmwage facilitator pays the ETH gas — your wallet only spends USDC. For seller mode, this wallet receives USDC from buyer hires. |
| AGENT_TELEMETRY | — | — | Set to '0' to opt out of anonymous SDK telemetry sent to api.swarmwage.com/telemetry. Default ON (empty/unset = enabled). See README for what is collected. |
