Rare Evo 2025: the multi-day blockchain/Web3 conference Rare Evo, recently concluded in Las Vegas, saw many new developers and protocol teams presenting new ideas and innovative applications of blockchain technology.
Among these, one project that caught attention was KWARXS, led by Sandro González, whose goal is to make solar energy accessible and affordable. Sandro has built 5.9 GW of solar infrastructure over 18 years and is now tokenizing it on Cardano as NFTs with real yield. Recently, they secured $280,000 in funding from Project Catalyst and have a VARA license in process.
At Rare Evo 2025, KWARXS stood out by promising to channel 5.5 gigawatts of global solar power capacity into a tokenized investment model on the Cardano blockchain.
It does not attempt to greenwash, but rather presents a structured and on-chain financial product that merges real-world performance with decentralized finance.
KWARXS aims to achieve this by allowing fractional ownership of solar parks through mintable NFTs. These NFTs represent a share of the actual solar infrastructure and not speculative tokens. Each NFT grants its holder the right to a portion of the annual profits from the solar power plants, distributed in ADA.
According to the project, these real solar assets are operated by a team with 5.5 GW of solar projects in various formats (rooftops, floating, landfills, carports) across more than a dozen countries.
This approach will allow small investors to co-own solar assets without high capital barriers and will help open a new class of investment.
According to its Catalyst proposal, the success metrics of the platform are:
▫️Installed capacity (MW) through Cardano-backed investments,
▫️Count of individual investors, especially from small participants, democratizing access to renewable energies.
The yield potential of these tokens could also be linked to actual electricity sales and power purchase agreements (PPAs), generating stable returns.
The KWARXS proposal seems clear: to buy a share of an operational solar plant through a mintable Cardano NFT. The plant's profits are converted to ADA and distributed through a profit-sharing validator on-chain that ensures fair claims.
Its plan also includes the creation of a utility NFT marketplace, where only whitelisted NFTs backed by utilities can be traded. This comes after a surprising 94% increase in market capitalization last month, reaching $6.6 billion. This has been driven by a $5 million CryptoPunk sale and explosive growth in top-tier collections like Pudgy Penguins.
As governments and companies accelerate towards net-zero commitments, tokenized green energy assets offer both compliance and reputational advantages.
If KWARXS delivers on its promises, it could create a replicable framework for the tokenization of renewable energy assets. This could also drive adoption by turning 5.9 GW of solar power into investable, tradable, and fully transparent financial products.
