Lightspark partners with Turnkey to launch Grid Global Accounts

Lightspark, San Francisco, USA – April 28, 2026: Lightspark, the company behind the Spark Bitcoin Layer 2 network and the Grid payments API, is launching Grid Global Accounts, a product that allows any platform to offer branded dollar accounts to its users anywhere in the world. 

Grid Global Accounts combine the reach of traditional banking infrastructure with the speed and programmability of stablecoin rails, creating what the company calls the most fungible dollar balance ever built. 

What Grid Global Accounts enable

Grid Global Accounts give platforms a single integration point to offer their users a dollar balance with unprecedented reach. That balance can move in real time across more than 65 domestic and global banking rails, from ACH and SEPA to local payment schemes across emerging markets.

Beyond traditional rails, account holders can spend directly using a Visa debit card, giving platforms the ability to issue branded debit cards to their users without intermediary card program managers.

Grid Global Accounts also support cross-chain compatibility with dozens of blockchain networks and stablecoins, allowing account balances to flow between fiat and crypto settlement with no manual bridging. 

And for platforms building with AI, secure agent delegation (currently in beta) lets users connect their AI agent of choice to their Grid account, enabling autonomous money movement within platform-defined controls.

What Turnkey powers inside Grid Global Accounts

Turnkey provides the wallet infrastructure underneath Grid Global Accounts, handling the signing, key management, and policy enforcement that help make the product's most distinctive features possible.

• Cross-chain stablecoin compatibility — signing across dozens of chains from a single account
• Secure agent delegation — policy-based signing so platforms can safely connect AI agents to accounts
• Non-custodial key management — users and platforms own their keys, not Lightspark, not Turnkey

“Lightspark is building an incredibly ambitious payment product, setting a high bar for financial infrastructure going forward,” said Bryce Ferguson, CEO and co-founder of Turnkey. “Turnkey exists to make products like this possible.”

Why embedded wallets are the right model for this new product release

Grid Global accounts use the same embedded wallet pattern that Turnkey powers for consumer trading apps like Moonshot and Axiom, DeFi platforms like Infinex and OneBalance, and payments companies like Mural Pay and Flutterwave. 

The difference with Grid Global Accounts is scope: the wallet is not just holding crypto. It is the settlement layer for a dollar account that spans banking rails, card networks, and blockchain protocols simultaneously.

The future of financial infrastructure

Grid Global Accounts point to a clear shift in how money moves and how financial systems are built.

Stablecoin adoption is accelerating across remittances, payroll, and B2B payments, and agentic finance, where AI systems manage and move money on behalf of users, is moving from research demos to production beta.

Turnkey’s role in Grid Global Accounts reflects how the infrastructure layer is becoming the execution backbone for these systems. The result is a new class of financial products that no longer resemble traditional crypto wallets, but operate entirely on crypto rails.
