All contracts on the 482120 side are verified on explorer.btcw.tech
(the ISM of each bridge core — 0x6003…e817 for USDC/USD₮0, 0xf6c9…06a3 for the sealed WBTC route — is a 214-byte
EIP-3448 MetaProxy with no source of its own; their implementations 0xb296e5632e2957c6fcda3efcc0fcf758ee5ddb54 and
0x1f8410baba198fa9d467bc028a199b3501a2c880 are verified). Arbitrum side: exact match on
Sourcify / arbitrum.blockscout.com. Machine-readable version (addresses + ABIs): /developers/contracts.json.
Always identify assets by chainId + address. Symbols such as BTCW and USDW are already used by unrelated assets on other chains.

Owner and Treasury wallets
Published so you can filter or monitor them yourself:
| Role | Address |
|---|---|
| Owner — owns every contract above, on both chains | 0x4aFd0A931176103d704Ff0d696614d4E10d74A4a |
| Owner wallet B — owns the dedicated core, its routes, WBTCw and the Uniswap V2 pool | 0xB17bdA8F14EEb9fd67B34810A2e1E82A737Ad952 |
| Treasury arbitrage bot (USDw pool) | 0x4b3418e3d21932610faafef8caefdb0f2c05a836 |
The Dashboard and /api/v2/stats report the volume of the bot and OracleRebalancer separately (the treasury_addresses field) — these are the trades
that keep pool prices near the oracle. Owner permissions: Trust model.
