XRP Ledger (XRPL) RWA Platform Launches in Japan With Tokenized Green Power Demo

TLDR

• Digital Platformer launched an XRPL-based RWA trading proof of concept in Japan.
• The first use case tokenizes solar green electricity certificates on-chain.
• Green power is divided into 30-minute blocks with generation metadata.
• The platform uses XRPL’s Multi-Purpose Token standard for certificate issuance.
• Digital Platformer plans to expand into carbon credits and digital securities.

Tokyo-based blockchain company Digital Platformer has launched a proof-of-concept for a real-world asset trading platform built on the XRP Ledger, starting with tokenized green electricity certificates linked to solar power generation.

The project uses electricity generated by iGrid Solutions’ solar facilities across Japan and converts renewable energy output into digital certificates in 30-minute increments. Each certificate includes data tied to the generation period, power source, and geographic region, allowing the asset to be issued, tracked and circulated on-chain.

The demonstration marks a new use case for the XRP Ledger in real-world asset infrastructure. Digital Platformer said the system is designed to improve the way environmental value is recorded and traded, especially as companies and energy users seek more accurate proof of renewable power consumption.

Tokyo Platform Tokenizes Green Power

Digital Platformer, based in Chiyoda-ku, Tokyo, is conducting the project with iGrid Solutions, an energy technology company headquartered in Minato-ku. The initial asset class is green power generated from solar energy, which is divided into 30-minute blocks and managed as digital certificates with expiration dates.

Traditional green power certificates are often tracked on monthly or annual schedules. That can create a gap between when renewable electricity is generated and when it is counted as consumed. The new platform aims to reduce that timing gap by linking each certificate to a shorter generation window.

The model also addresses growing scrutiny around greenwashing. By recording generation details more frequently, the system can provide clearer matching between renewable energy output and consumption claims. The structure is aligned with international efforts such as EnergyTag, which supports more time-based electricity certification.

Each tokenized certificate carries metadata, including the time of generation, solar as the generation type and the region where the electricity was produced. This creates a record of the environmental attribute tied to each unit of power.

MPT Standard Records Energy Attributes

The platform uses the XRPL Multi-Purpose Token standard, known as MPT. The standard allows multiple balances to be managed under a single token ID while still carrying detailed asset data.

In this case, green electricity generation volume is represented as an MPT balance. That allows Digital Platformer to issue and manage energy certificates in smaller units than older certificate systems. It also supports transfer and circulation controls for the certificates as they move between users.

Digital Platformer has built the system using its work in digital identity, digital currency and blockchain-based settlement. Keio University’s Future Optical Network Open Research Center is serving as an adviser for the demonstration, providing energy-sector expertise during verification.

The company has also secured a patent for blockchain-based power trading technology that supports peer-to-peer electricity transactions. The current green power certificate demo is part of its wider effort to apply blockchain systems to energy markets and asset digitization.

Digital Platformer plans to expand the RWA platform beyond green electricity certificates. Carbon credits, digital securities and regional assets are listed as future areas for development. The expansion would place additional real-world assets on a blockchain-based framework using similar issuance and tracking methods.

XRP Activity Extends to ETFs and Payments

The Japan-based RWA demo arrives as institutional attention around XRP and the XRPL continues to grow. Grayscale Managing Director of Research Zach Pandl has said XRP exchange-traded funds could absorb about 5% to 6% of the circulating XRP supply, excluding assets already held under management.

That estimate refers to tokens potentially locked into ETF structures if XRP funds follow adoption patterns already seen in Bitcoin and Ethereum ETFs. XRP market participants are watching the forecast because ETF demand can affect the available liquid supply.

The XRP Ledger Foundation also said Mastercard plans to expand its integration with the XRP Ledger to support always-on settlement and time-sensitive intraday payment flows. The foundation cited the network’s near-instant finality, low fees, and 14-year operating record as reasons for its use in payment settlement.

The XRPL marked its 14th anniversary on June 3. The network was originally designed for faster value transfer and has since been used across payments, token issuance, and settlement-related applications.
