 Chainlink's Cross-Chain Interoperability Protocol (CCIP) is designed to evolve in response to new feature requests, security considerations, and the need to support additional blockchains over time. This requires a secure upgrade process that preserves CCIP's robust security while allowing for iterative improvements.

 This section outlines the operational limits for Chainlink CCIP across different blockchain architectures.
 
 - **[EVM Service Limits](/ccip/service-limits/evm)**: Service limits for Ethereum and other EVM-compatible blockchains.
 - **[Solana Service Limits](/ccip/service-limits/svm)**: Service limits for Solana.
+- **[Aptos Service Limits](/ccip/service-limits/aptos)**: Service limits for Aptos.
 - **[Network-Specific Limits](/ccip/service-limits/network-specific-limits)**: Documented network-specific limitations (all blockchain families).
 
 Understanding these limits is essential for building reliable cross-chain applications that operate within CCIP's intended parameters.

+## Understanding Named Addresses in the Manifest File (`Move.toml`)
+
+The Move build system uses a manifest file, `Move.toml`, to define a package, its dependencies, and any named addresses it references. Named addresses are human-readable aliases for on-chain hexadecimal addresses, which makes the Move code cleaner, more readable, and easier to manage.
+
+When you compile a Move package, the compiler replaces these aliases (e.g., `@ccip_router`) with their actual address values from the `Move.toml` file.
+
+In the [`aptos-starter-kit`](https://github.com/smartcontractkit/aptos-starter-kit), the example modules (like `ccip_message_sender`, `ccip_message_receiver`) need to interact with the core CCIP modules already deployed on the Aptos Testnet. The `[addresses]` section in their `Move.toml` files provides the necessary references.
+
+**Example `Move.toml` Address Block:**
+
+```toml
+[addresses]
+ccip = "0xc748085bd02022a9696dfa2058774f92a07401208bbd34cfd0c6d0ac0287ee45"
+mcms = "0xbdf1b9aacb4e21bf6f255105831df0172e911d4748e488196fde10d2e2a4e32d"
+mcms_register_entrypoints = "0x0"
+ccip_onramp = "0xc748085bd02022a9696dfa2058774f92a07401208bbd34cfd0c6d0ac0287ee45"
+ccip_router = "0xc748085bd02022a9696dfa2058774f92a07401208bbd34cfd0c6d0ac0287ee45"
+```
+
+Here is a breakdown of what each named address represents:
+
+- **`ccip`**: This is the main **Object address** under which the core CCIP packages and their modules (like `fee_quoter`, `rmn_remote`, `token_admin_registry`, etc.) are published.
+
+- **`ccip_router`** & **`ccip_onramp`**: These aliases also point to the main CCIP Object address. This is because the `router` and `onramp` modules are part of the packages published under that single, unified Object. The aliases are defined for clarity and consistency in the Move code's `use` statements.
+
+- **`mcms`**: This is the address of the on-chain **ManyChainMultiSig (MCMS)** module, which is responsible for handling governance and administrative actions for the CCIP protocol through a secure, time-locked [implementation process](/ccip/concepts/architecture/onchain/aptos/upgradability#implementation-process).
+
+- **`mcms_register_entrypoints`**: This is a special value used as a **compile-time flag**. By setting it to `0x0`, the module is compiled in a way that bypasses the logic for registering with the MCMS system. This is useful for certain testing or deployment scenarios where the MCMS module is not relevant.
+
+By defining these addresses in the `Move.toml` file, the example modules can interact with the core CCIP protocol without hardcoding long addresses, making the code portable and easier to update for different networks.
+
+<Aside type="note" title="Mainnet Addresses">
+  For the corresponding Aptos Mainnet addresses, refer to the [CCIP
+  Directory](/ccip/directory/mainnet/chain/aptos-mainnet).
+</Aside>
+
 ## Wallets
 
 - **EVM Wallet and Private Key**: To send transactions from an EVM chain (like Ethereum Sepolia), you need a wallet and its private key.
