Startale Launches Onchain Finance Suite for Institutions and Self-Custodial Visa Card

Startale is expanding beyond blockchain infrastructure into a broader onchain finance platform.

At WebX 2026 in Tokyo, the company unveiled two new products aimed at accelerating blockchain adoption on both sides of the market: Startale Onchain Finance Kits (OFK), a software suite that helps financial institutions launch regulated onchain financial services, and Startale Card, a self-custodial Visa card that lets consumers spend assets held on Sony-backed Layer-2 network Soneium anywhere Visa is accepted.

Together, the launches mark Startale's latest push to bridge traditional finance with blockchain-based payments, assets and financial services.

Helping Financial Institutions Move Onchain

As financial institutions move beyond blockchain experimentation toward production deployments, many still face the challenge of building compliant digital asset infrastructure.

Startale believes it has already done much of that work.

Through projects including Soneium, JPYSC, Strium and the Startale App, the company has spent several years building blockchain infrastructure spanning stablecoins, institutional trading, tokenization, privacy and settlement.

That experience has now been packaged into Startale Onchain Finance Kits (OFK), allowing financial institutions to deploy modular infrastructure instead of building core blockchain capabilities from scratch.

The modular platform includes:

• Stablecoin infrastructure

• Wallet infrastructure

• Digital asset tools

• Privacy infrastructure

• Developer infrastructure

• Blockchain and settlement infrastructure

Startale plans to further expand OFK with tokenization infrastructure and custody wallet APIs, giving financial institutions additional tools to build regulated digital asset products.

"Financial institutions are no longer asking whether onchain finance will become part of the future financial system. They are asking how to participate," said Sota Watanabe, CEO of Startale Group.

"OFK represents the experience, infrastructure, and expertise we have built over years of working with enterprises and institutions. Our goal is to help organizations move faster, reduce complexity, and unlock new opportunities in the onchain economy."

Turning the Startale App Into a Financial Super App

Alongside its institutional offering, Startale also introduced Startale Card, a self-custodial Visa card that connects digital assets to everyday spending.

Built on Soneium, the Ethereum Layer-2 developed with Sony Group, the card allows users to spend eligible onchain assets at more than 150 million merchants worldwide wherever Visa is accepted.

Unlike many crypto cards that require assets to be transferred into custodial accounts before they can be spent, Startale Card lets eligible holdings continue generating yield until they're used for payment. Users also receive cashback in USDSC, Startale's US dollar stablecoin.

The launch marks the next evolution of the Startale App, which already combines asset management, trading, rewards and Mini Apps in a single platform. Future updates will introduce yield-generating vaults, enabling users to earn passive returns while maintaining access to the same assets for everyday purchases.

"We've always believed onchain technology should improve everyday financial experiences, not complicate them," said Watanabe.

"With Startale Card, Startale App evolves into a platform where users can seamlessly manage, grow, and spend their wealth. This marks a major milestone in our vision to become the App for More than Money."

Building Both Sides of the Onchain Economy

The simultaneous launch of OFK and Startale Card highlights Startale's strategy of serving both institutional finance and retail users through a single ecosystem.

While OFK gives banks, enterprises and financial institutions the infrastructure needed to launch blockchain products more quickly, Startale Card focuses on bringing practical utility to consumers by making digital assets easier to use in everyday life.

The Startale Card waitlist is now open through the Startale App ahead of its public rollout.

With infrastructure spanning stablecoins, tokenization, blockchain settlement, payments and consumer finance, Startale is positioning itself to become one of the companies building the rails that connect traditional financial systems with the next generation of onchain services.
