# Contract Addresses

> Deployed Monolith contract addresses

Monolith consists of a small set of singleton contracts per chain, plus per-instance `Lender`, `Coin`, and `Vault` contracts deployed by the `Factory`.

## Singletons

### Ethereum Mainnet

## Discovering per-instance contracts

Each stablecoin instance consists of three contracts deployed by `Factory.deploy(DeployParams)`:

* **Lender** — core lending contract for the instance
* **Coin** — ERC‑20 stablecoin for the instance
* **Vault** — ERC‑4626 staked vault for the instance

Enumerate existing instances by reading the Factory:

```solidity theme={null}
uint256 count = factory.deploymentsLength();
address lender = factory.deployments(i);      // i < count
address coin   = address(Lender(lender).coin());
address vault  = address(Lender(lender).vault());
```

Or index the `Deployed(address indexed lender, address indexed coin, address indexed vault)` event emitted by the Factory on each `deploy()` call.

## Interest model

A single `InterestModel` instance is deployed per chain by the `Factory` constructor. Read its address from the Factory:

```solidity theme={null}
address interestModel = factory.interestModel();
```
