Common Infrastructure

Shared Contracts

Some contracts are shared across multiple vaults:

Lens Contract (Multi-chain)

• Address: 0x5232bc0F5999f8dA604c42E1748A13a170F94A1B
• Used on: Mainnet, Arbitrum, Base, Optimism
• Purpose: Helper functions for reading vault state

Integration Quick Start

Mainnet Liquid ETH Example

// Import interfaces
import {BoringVault} from "src/base/BoringVault.sol";
import {TellerWithMultiAssetSupport} from "src/base/Roles/TellerWithMultiAssetSupport.sol";
import {AccountantWithRateProviders} from "src/base/Roles/AccountantWithRateProviders.sol";

// Initialize contracts
BoringVault vault = BoringVault(0xf0bb20865277aBd641a307eCe5Ee04E79073416C);
TellerWithMultiAssetSupport teller = TellerWithMultiAssetSupport(0x5c135e8eC99557b412b9B4492510dCfBD36066F5);
AccountantWithRateProviders accountant = AccountantWithRateProviders(0x0d05D94a5F1E76C18fbeB7A13d17C8a314088198);

// Deposit WETH
IERC20 weth = IERC20(0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2);
weth.approve(address(teller), amount);
uint256 shares = teller.deposit(weth, amount, minShares);

Arbitrum Liquid ETH Example

// Same contract addresses as Mainnet
BoringVault vault = BoringVault(0xf0bb20865277aBd641a307eCe5Ee04E79073416C);
TellerWithMultiAssetSupport teller = TellerWithMultiAssetSupport(0x5c135e8eC99557b412b9B4492510dCfBD36066F5);

// Different WETH address on Arbitrum
IERC20 weth = IERC20(0x82aF49447D8a07e3bd95BD0d56f35241523fBab1);

Verification

All contracts are verified on their respective block explorers:

• Mainnet: Etherscan
• Arbitrum: Arbiscan
• Optimism: Optimistic Etherscan
• Base: Basescan
• Avalanche: Snowtrace
