# Bridge Guide - Mainnet

The Tajir Mainnet Bridge supports transfers between Ethereum Mainnet and Tajir Chain.

Bridge interface:

### Mainnet Contracts

<table data-search="false"><thead><tr><th width="350">Contract</th><th>Address</th></tr></thead><tbody><tr><td>TJR Ethereum Proxy</td><td>0x9D98C61d1136cfA2ac263Be355350C97Ca41c110</td></tr><tr><td>AggLayer Bridge on Ethereum</td><td>0x2a3DD3EB832aF982ec71669E178424b10Dca2EDe</td></tr><tr><td>AggLayer Bridge on Tajir Chain</td><td>0x2a3DD3EB832aF982ec71669E178424b10Dca2EDe</td></tr><tr><td>AggLayer Manager</td><td>0x5132A183E9F3CB7C848b0AAC5Ae0c4f0491B7aB2</td></tr><tr><td>Tajir Rollup Contract</td><td>0xB07134fF28e74a90667Ab5e3F7271a542D6E0358</td></tr><tr><td>AggLayer Rollup ID</td><td>28</td></tr></tbody></table>

> **Note:** The AggLayer Bridge uses the same contract address on both chains; however, these are distinct contracts with different code hashes and network IDs (`0` and `28`, respectively).&#x20;

### Important Safety Notice

Do not send tokens directly to a bridge contract unless the documented bridge method explicitly requires it. A plain ERC-20 transfer to a bridge address does not automatically create a tracked bridge deposit.

Use the official bridge interface or the documented smart-contract functions.

Always verify:

* Source and destination networks
* Asset address
* Bridge contract
* Destination wallet
* Network fees
* Transaction status
* Claim status

Withdrawal and claim availability depend on the bridge processing and settlement state. The interface displays when a withdrawal becomes claimable.
