# Contract Addresses
> Every contract Ozmium can build a transaction against, with its Base address, its operator, and its audit status - checkable line by line on Basescan.

One list, every destination. The interface builds transactions only against the contracts below,
each published and operated by the protocol named beside it. Verify any row on
[Basescan](https://basescan.org) and against the protocol's own documentation before you sign -
that check depends on nobody's honesty, including ours.

:::note This list cannot silently drift
The app's own Terms sheet derives the same list directly from the modules that call each address.
This page is checked against the app source at every docs build: if an address printed here stops
appearing in the code, the build fails and the site cannot deploy with a stale row.

**Audited** means the protocol publishes independent third-party audits of that contract. It is
never a claim about the Ozmium interface itself, which is unaudited and says so. Avantis publishes
audits by Zellic and Zokyo, with a Sherlock review of v1.5. OZ is deliberately marked unaudited:
it is source-verified onchain - a real, checkable property, and a weaker claim than audited.

## Runtime-Resolved Destinations

Four destinations are chosen at runtime rather than pinned at build time. They are called out
rather than hidden, because "we only ever call contracts we chose" is the interesting claim and
these are its exceptions:

- **Moonwell markets.** Each market is its own mToken contract, published by Moonwell and read
  from the comptroller at runtime; the interface supplies to, borrows from, and repays those
  mTokens directly.
- **Morpho vaults.** Individual vaults are ERC-4626 contracts published by Morpho and read at
  runtime. Each is shown with its address before you deposit.
- **Swap settlement.** The swap route quotes a settlement contract from the Coinbase Developer
  Platform. The interface refuses to approve any spender other than the pinned Permit2 address
  above.
- **Limitless.** Prediction-market portfolios are read from their public API, read-only. The
  interface currently builds no transactions against Limitless contracts; if that changes, the
  addresses join this page first.
