Network Details
Chain ID, RPC and WebSocket endpoints, explorer URL, native token, and the L1 + L2 contract addresses you may need to reference.
The canonical reference for adding Mandala to wallets, RPC clients, and dApps. Pin these values; they should not change.

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.
| Contract | Address | Purpose |

| Rollup | 0x218D35154D1efEBFC46D64451C9495288219b275 | State assertions and dispute game. |
| SequencerInbox | 0x325acf46079d3f750D5D7E6182E094B1fD0AC2F4 | Where the batch poster posts batches. Force-inclusion is finalized here. |
| 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. |
