Baseline Mercury uses a singleton contract pattern that lives at the same address on every deployed EVM chain: **0xc81Fd894C0acE037d133aF4886550aC8133568E8**. All pools and protocol features (swapping, quoting, staking, borrowing and leveraging) are managed by this contract.

<Callout type="info">
  Use the [`@baseline-markets/cli`](/docs/contracts/cli) to build launch calls, install agent skills, execute with an explicit signer, and inspect deployed tokens. Most app integrations should use [`@baseline-markets/sdk`](/docs/contracts/sdk), a TypeScript SDK for launching tokens, and integrating swapping, staking, borrowing and leveraging functionality. The contract pages in this section are the ABI-level reference for raw, low-level access.
