# LayerZero V2 IOTA L1 Packages

> Overview of IOTA L1 Packages on LayerZero V2. Learn the architecture, features, and how to get started building. LayerZero enables secure crosschain messaging.

The LayerZero Protocol on IOTA L1 consists of several Move packages designed to facilitate the secure movement of data, tokens, and digital assets between different blockchain environments.

LayerZero provides [**IOTA L1 Move Packages**](https://github.com/LayerZero-Labs/LayerZero-v2/tree/main/packages/layerzero-v2/iota/contracts) that can communicate directly with the equivalent [Solidity Contract Libraries](/v2/developers/evm/overview) and other blockchain implementations deployed across supported chains.

## IOTA L1 and LayerZero

IOTA L1 uses the [Move programming language](https://docs.iota.org/developer/iota-101/move-overview/move-overview) and employs a unique execution model based on [**Programmable Transaction Blocks (PTBs)**](https://docs.iota.org/developer/iota-101/transactions/ptb/programmable-transaction-blocks) and the **Call pattern** (a hot potato implementation using Move's [ability system](https://move-book.com/reference/abilities) where objects without `drop` or `store` must be explicitly consumed) to achieve crosschain functionality without traditional dynamic dispatch.

### Tooling and Resources

IOTA L1 development relies on the [Move programming language](https://docs.iota.org/developer/iota-101/move-overview/move-overview) and the [IOTA CLI](https://docs.iota.org/developer/references/cli). For comprehensive information, see the [IOTA Documentation](https://docs.iota.org/).

LayerZero provides developer tooling to simplify the package development, testing, and deployment process:

**LayerZero Scan**: a comprehensive block explorer, search, API, and analytics platform for tracking and debugging your omnichain transactions.

**TypeScript SDKs**:

* [`@layerzerolabs/lz-iotal1-sdk-v2`](https://www.npmjs.com/package/@layerzerolabs/lz-iotal1-sdk-v2): Core SDK for interacting with LayerZero on IOTA L1
* [`@layerzerolabs/lz-iotal1-oft-sdk-v2`](https://www.npmjs.com/package/@layerzerolabs/lz-iotal1-oft-sdk-v2): OFT-specific SDK for token operations
