Tether Speed Investment Backing Lightning Stablecoin Rails

In a move to expand real-world crypto payments, Tether speed investment is targeting new Lightning-based infrastructure for instant settlement and stablecoin commerce.

Tether leads $8 million round into Speed

On 16 December 2025, Tether, the largest company in the digital assets industry, announced a strategic investment in Speed1, a payments infrastructure firm focused on the Bitcoin Lightning Network and stablecoins. Tether led Speed’s $8 million funding round together with ego death capital, underscoring its push into Lightning-native rails.

Speed operates instant, global settlement infrastructure that processes more than $1.5 billion in annual payment volume across consumers, creators, platforms, and enterprise merchants. Its core products, Speed Wallet and Speed Merchant, serve 1.2 million users and businesses, delivering native BTC and USDT settlement and high-reliability global routing for enterprise integrations.

Moreover, Tether’s backing highlights how Lightning and stablecoins can be combined to create low-cost, high-throughput payment rails. The firm describes Speed’s stack as a blueprint for moving money at scale with low fees, strong compliance, and global reach, all anchored to Bitcoin-aligned infrastructure.

Building Lightning-native, stablecoin-powered payments

The strategic tether speed investment supports Tether’s broader strategy to reinforce Bitcoin-rooted financial infrastructure and extend USDT‘s utility in real-world payment environments. According to the company, this approach is designed to reduce friction in day-to-day spending while preserving the open, permissionless qualities of Bitcoin-based networks.

“Speed is showing what Lightning can achieve when paired with a stable, liquid digital dollar like USDT,” said Paolo Ardoino, CEO of Tether. “We support teams building practical infrastructure that reduces friction in payments and expands access to reliable settlement rails. Speed’s execution and adoption signal that Bitcoin-rooted networks are ready for mainstream commerce.”

That said, Speed’s vision goes beyond speculative trading and into everyday payments. “Crypto has lived in the world of speculation for too long. Speed is making it usable – instantly, globally, and at scale. Lightning gives us speed; stablecoins give us universal access; our infrastructure brings it all together for consumers, creators, and merchants,” said Niraj Patel, CEO of Speed1, Inc.

Speed integrates tightly with the Lightning Network while enabling stablecoin settlement for users and merchants who require price stability. This combination reduces friction for cross-border transactions, creator payouts, merchant payments, and platform-level settlement, positioning Speed as a key player in next-generation digital payment rails.

Tether Investments and its broader strategy

However, the Speed deal also fits into the larger mandate of Tether Investments, the independent investment arm of Tether based in El Salvador. The firm deploys capital from Tether’s profits and excess reserves across sectors where technology, infrastructure, and real-world utility intersect, including financial services and energy.

Its portfolio includes investments in artificial intelligence, financial services, energy, biotechnology, education, and digital media. In addition, it holds strategic stakes in industries such as commodities, remittances, and sports and entertainment, reflecting a diversified view of digital and physical infrastructure.

Moreover, Tether Investments focuses on ventures with long-term potential to improve access, efficiency, and resilience in both emerging and developed markets. Its work supports Tether Group‘s mission to strengthen decentralized systems, promote infrastructure resilience, and expand real-world access to open, transparent technologies, with Speed positioned as a flagship example in payments.

So, Tether’s backing of Speed signals growing confidence in Lightning-based, stablecoin-enabled payment infrastructure and reinforces the company’s push to bring instant, global settlement into mainstream commerce.
