The Helium IOT token served as the foundational protocol token for the Helium IoT Network, a decentralized infrastructure supporting LoRaWAN connectivity. Introduced to the ecosystem through community governance proposal HIP-52, the IOT token became operational following the network's migration to the Solana blockchain on April 18, 2023. This token played a vital role in incentivizing network participants and facilitating machine-to-machine communication.
A significant transition occurred on January 15, 2025, when IOT token emissions officially ceased as outlined in HIP-138. Since that date, network participants receive rewards directly in HNT tokens based on the utility score allocated to the IoT Network. Despite this change, IOT tokens remain redeemable for HNT through the Subnetwork Treasury pool established during the IOT emission period.
Token Overview
The IOT token was designed to reward LoRaWAN Hotspot operators for both data transfer activities and Proof of Coverage validation. Participants could also earn IOT tokens by locking HNT tokens to participate in the Helium IoT Network's governance mechanisms, creating additional utility for network stakeholders.
The official mint address for IOT tokens on the Solana blockchain is iotEVVZLEywoTn1QdwNPddxPWszn3zFhEot3MfL9fns, which serves as the unique identifier for this digital asset within the ecosystem.
Conversion Process to HNT
Protocol tokens within the Helium ecosystem maintain their value through direct backing by HNT tokens. This design ensures that even after the transition to direct HNT rewards, IOT tokens can still be converted to HNT at a determined rate. The conversion mechanism operates through treasury swap contracts that algorithmically set the redemption ratio.
The conversion rate calculation involves dividing the total circulating supply of IOT tokens by the amount of HNT currently held in the IOT Network treasury. This calculation determines how many IOT tokens must be burned to receive one HNT token from the treasury pool.
With IOT minting ceased and no further HNT distributions to the IOT treasury, the redemption rate between IOT and HNT has stabilized. The IOT token maintains value as long as HNT remains in the dedicated treasury pool, providing ongoing utility for token holders.

No automatic migration process from IOT to HNT exists currently, requiring token holders to actively participate in the conversion process through available tools and platforms.
Token Distribution and Emission Schedule
The IOT token followed a minting schedule similar to HNT but with a maximum supply of approximately 70,000,000,000 (70 billion) tokens as established post-HIP-138. The emission schedule began Year 1 on August 1, 2022, though actual token distribution didn't commence until April 18, 2023, following the Solana migration.
The original emission plan included halving events every two years, synchronized with HNT issuance halvings. From January 2025 onward, while emission percentages remain consistent, all rewards are distributed directly in HNT tokens rather than IOT.
The allocation breakdown across different network functions remained consistent throughout the emission period:
- Proof of Coverage rewards decreased gradually from 30% to 21%
- Data Transfer rewards increased correspondingly from 50% to 59%
- Oracle rewards maintained a consistent 7% allocation
- Operations Fund maintained a consistent 7% allocation
- veHNT Stakes maintained a consistent 6% allocation
This structured allocation ensured balanced incentives for all network participants while supporting the growing infrastructure needs of the decentralized wireless network.
Conversion Methods and Tools
Token holders can convert IOT to HNT through several methods. The Helium Wallet App serves as the primary user-friendly interface for this conversion process, providing a streamlined experience for network participants. Alternatively, technically advanced users can perform conversions directly on the Solana blockchain using open-source tools available through Helium's GitHub repositories.
The conversion process involves burning IOT tokens in exchange for HNT from the network treasury, effectively reducing the circulating supply of IOT while maintaining the value proposition for token holders. This mechanism ensures that early network participants continue to receive appropriate value for their contributions to network growth and security.
Frequently Asked Questions
What was the purpose of the IOT token?
The IOT token served as the incentive mechanism for the Helium IoT Network, rewarding Hotspot operators for providing wireless coverage and handling data transfers. It created an economic system that encouraged network expansion and participation while maintaining decentralized governance through token-based voting.
Can I still convert my IOT tokens to HNT?
Yes, IOT tokens remain convertible to HNT through the Subnetwork Treasury pool. The conversion rate is determined algorithmically based on the remaining HNT in the treasury and the circulating supply of IOT tokens. This process will remain available as long as HNT exists in the treasury pool.
Why did the network transition from IOT to direct HNT rewards?
The transition streamlined the token economy and reduced complexity within the Helium ecosystem. By consolidating to a single primary token (HNT), the network improved interoperability between subnets and created a more unified economic model while maintaining the utility value of all previously earned rewards.
What happens to unconverted IOT tokens?
Unconverted IOT tokens remain redeemable for HNT through the established treasury mechanism. There is no expiration date for conversion, though the redemption rate may fluctuate based on treasury balances and token circulation. Token holders can convert at their convenience using available tools.
How does the redemption rate calculation work?
The redemption rate is calculated by dividing the total circulating IOT supply by the amount of HNT currently in the IOT Network treasury. This algorithmic approach ensures a fair and transparent conversion process that reflects the actual backing of each IOT token by HNT reserves.
Are there any fees associated with converting IOT to HNT?
Standard network transaction fees apply for blockchain operations, but there are no additional conversion fees beyond the algorithmic exchange rate. The process involves burning IOT tokens and receiving equivalent value in HNT based on the current treasury ratio.
