Weather has always influenced financial markets. Now it could become a blockchain-native asset in its own right.
Flare has partnered with South Korean weather data company Kweather to bring meteorological data onchain, laying the groundwork for a new generation of climate-focused financial products ranging from parametric insurance to weather derivatives and tokenized infrastructure.
The collaboration, announced under a newly signed Letter of Intent, will use Flare's decentralized oracle network to record and verify weather data directly onchain, creating tamper-proof datasets that can be trusted by financial institutions, insurers and blockchain applications.
Building Trust in Climate Data
At the center of the partnership is Flare's Time Series Oracle (FTSO), which will publish Kweather's meteorological data—including temperature, rainfall and other climate measurements—directly onto the blockchain.
Once recorded, the data becomes independently verifiable and immutable, providing developers and financial institutions with trusted inputs for smart contracts and climate-related financial products.
The approach removes reliance on centralized databases while creating transparent, auditable weather records that can be used across decentralized applications.
Bringing Climate Finance Onchain
The partners believe trusted weather data could unlock entirely new financial markets. Among the first products under consideration is parametric climate insurance, where payouts are triggered automatically when predefined environmental conditions—such as excessive rainfall, drought or heatwaves—are recorded, eliminating the need for lengthy claims assessments.
The companies also plan to explore blockchain-based weather derivatives, allowing businesses in sectors such as agriculture, energy, logistics and manufacturing to hedge against climate-related risks using verified onchain data.
