L1 (Ethereum) contracts
These are the Mandala core contracts deployed on Ethereum L1. They are the trust-relevant addresses: any reference to "Mandala on Ethereum" should match this set.

| Inbox (delayed) | 0x62DfD05c460C7E55DA85B39EaD3eBc6e0CcdD0d5 | Where users submit transactions when the sequencer is unresponsive (force-inclusion entry point). |
| Outbox | 0x004eF39261cee56409Dbd26040a33Eca8326490C | Where L2-to-L1 messages are released after the challenge window. |
