The decentralized ledger technology project IOTA is set to launch its long-anticipated IOTA 2.0 network upgrade in the fourth quarter of 2025. This major protocol evolution marks a transformative step for the ecosystem, aiming to bring full smart contract functionality directly to Layer 1, enhance token utility, and drive greater decentralization through community-led governance initiatives.
This upgrade is more than just a technical milestone—it's a strategic repositioning of IOTA within the broader blockchain landscape. By integrating native smart contracts at the base layer, IOTA aims to compete directly with leading smart contract platforms while maintaining its unique focus on feeless transactions and Internet of Things (IoT) scalability.
Core Features of IOTA 2.0
Native Smart Contracts on Layer 1
One of the most significant advancements in IOTA 2.0 is the introduction of programmable smart contracts directly on Layer 1. Unlike many blockchain networks that rely on Layer 2 solutions or sidechains for smart contract execution, IOTA’s approach embeds contract logic into the core protocol.
This architectural decision enhances security, reduces latency, and simplifies developer experience by eliminating cross-layer dependencies. Developers will be able to deploy decentralized applications (dApps) with seamless interoperability across the entire IOTA ecosystem.

Transition from Assembly to IOTA Chains
In a strategic shift, the IOTA Foundation has announced it will discontinue further development of the Assembly project and will not issue the previously planned Assembly token. Instead, resources are being redirected toward IOTA Chains, a universal smart contract framework designed for flexibility, security, and cross-chain compatibility.
IOTA Chains will serve as the primary environment for dApp development, offering developers modular tools, customizable consensus mechanisms, and interoperable runtime environments. This pivot reflects a broader industry trend toward generalized, scalable smart contract infrastructures.
Decentralized Governance and Ecosystem Funding
Launch of a New Ecosystem Fund
To support sustainable growth and decentralization, IOTA is establishing a new ecosystem fund backed by an initial supply increase of MIOTA tokens. The total token supply will rise to 4.6 billion MIOTA through a four-year temporary inflation mechanism, with newly issued tokens allocated exclusively to fund ecosystem development and community incentives.
This fund will operate under decentralized governance, empowering the community to shape the future of the network through participatory decision-making.
Community Governance Tools and Committees
The ecosystem fund will be managed via a suite of on-chain governance tools, including voting portals, proposal submission systems, and transparent budget dashboards. Additionally, multiple governance committees and legal entities will be formed to oversee fund distribution, ensure compliance, and maintain operational accountability.
These structures are designed to gradually transition control from the IOTA Foundation to the global community—a critical step in achieving true decentralization.
Technical Roadmap and Upcoming Milestones
Stardust Hard Fork: Laying the Foundation
Before the full rollout of IOTA 2.0, the network will undergo the Stardust hard fork, scheduled for release on October 4, 2025. Stardust serves as a foundational upgrade, introducing key features such as:
- Account model implementation
- EVM compatibility
- Enhanced wallet functionality
- Improved user experience for dApp interactions
Stardust effectively bridges the legacy IOTA network with the upcoming IOTA 2.0 architecture, enabling smoother migration and early adoption of new capabilities.
Timeline for IOTA 2.0 Rollout
While an exact date has not been confirmed, the fourth-quarter 2025 launch window positions IOTA 2.0 as one of the most anticipated blockchain upgrades of the year. The phased rollout will likely include:
- Testnet deployment – Allowing developers to experiment with smart contracts and governance tools.
- Security audits and optimizations – Conducted by independent firms to ensure robustness.
- Mainnet launch – Full activation of IOTA 2.0 with decentralized consensus and live dApp deployment.
Developers and ecosystem partners are already preparing infrastructure, SDKs, and tooling to support the transition.

Why IOTA 2.0 Matters for Blockchain Evolution
IOTA has always differentiated itself through its Tangle architecture, a directed acyclic graph (DAG) that enables feeless microtransactions—ideal for IoT devices and machine-to-machine economies. With IOTA 2.0, the project combines this unique scalability advantage with full smart contract functionality, creating a compelling alternative to traditional blockchain designs.
This convergence could unlock new use cases in areas such as:
- Smart cities – Real-time data exchange between sensors and municipal systems.
- Supply chain tracking – Immutable, automated verification of goods movement.
- Decentralized identity – Secure, user-controlled digital identities powered by smart contracts.
- Machine economy – Autonomous devices that can pay for services like electricity or bandwidth.
