Polygon Acquires Sequence to Power Enterprise-Grade Smart Wallet Infrastructure for Stablecoin Payments

TLDR:

  • Polygon Labs acquired Sequence to eliminate wallet fragmentation blocking institutional stablecoin payment adoption at scale. 
  • Sequence Smart Sessions sandbox app-level permissions, reducing signature prompts while preserving non-custodial wallet security controls. 
  • Timed recovery keys in Sequence prevent silent account takeovers, meeting enterprise security standards for production payment systems. 
  • Polygon’s low fees and fast finality make Sequence’s cross-chain smart wallet features viable for real-world payment infrastructure.

 

Polygon Labs has acquired Sequence, a non-custodial smart wallet provider built for ecosystems and apps. The move brings together enterprise-grade wallet infrastructure and high-efficiency blockchain rails.

Together, the two aim to remove long-standing blockers preventing institutions from launching production-ready stablecoin payment products.

The combination addresses key pain points around authentication, recovery, permissions, and compliance controls that have slowed adoption in real-world payment environments.

Wallet Fragmentation Has Long Blocked Production Payment Systems

Account fragmentation remains one of the most persistent problems for payments teams building on blockchain. Users often end up with multiple wallet addresses depending on which app they used to sign in, leading to stranded balances and inconsistent account states. This creates operational complexity that few enterprise teams can manage at scale.

Traditional wallets were designed for asset custody, not operational money movement. A single private key controlling all permissions creates an all-or-nothing authority model.

Any move to delegate access or automate transactions increases risk without clear boundaries, making compliance reviews difficult.

Recovery presents an equally serious problem. Simple recovery paths open the door to silent takeovers. Stronger recovery processes introduce friction that leads to failed transactions and increased support costs. Neither option suits a production payment environment.

Polygon recently shared how this acquisition changes the equation for institutions: “With the recent acquisition of Sequence by Polygon Labs, there’s now a robust, enterprise-grade wallet offering, in conjunction with widely-adopted, highly-efficient blockchain rails.”

Operations teams also struggle to reason about fund controls. Without a clear model for who can move money, under what conditions, and for how long, compliance teams cannot complete proper security reviews or respond effectively to incidents.

Sequence Brings Smart Sessions and Sandboxed Permissions to Polygon

Sequence addresses these problems through a set of features designed specifically for payment-grade environments.

Smart Sessions allow each app to operate within sandboxed, clearly defined permissions rather than broad approvals. Users set session limits upfront, reducing signature prompts without sacrificing control.

Timed recovery keys add another layer of security. They provide time-based recovery mechanisms that prevent silent account takeovers, a critical requirement for any financial application handling real funds.

Hardware-isolated signing and verifiable attestations meet the expectations of enterprise security teams.

For developers, Sequence provides SDKs across Web, Mobile, Unity, and Unreal, with built-in flows for authentication, session management, and transaction handling.

Ecosystems can launch branded wallets on their own domains with admin controls for chains, branding, and session policies.

Polygon’s role in this setup is to provide fast finality and low, predictable transaction costs. That reliability makes features like Smart Sessions and cross-chain behavior viable at scale.

US Sanctions Ring Enabling North Korea IT Worker Fraud

US Sanctions Ring Enabling North Korea IT Worker Fraud

The US Treasury has sanctioned six people and two entities for their alleged roles in an IT worker fraud scheme orchestrated by  North Korea, which frequently targets the crypto industry.

The Office of Foreign Assets Control (OFAC) said on Thursday that it sanctioned alleged facilitators of the IT worker fraud networks operating in North Korea, Vietnam, Laos and Spain, which generate revenue to fund North Korea’s weapons program.

OFAC sanctioned Amnokgang Technology Development Company, a DPRK firm accused of managing overseas IT workers, and Nguyen Quang Viet, CEO of Quangvietdnbg International Services Company Limited, a Vietnam-based company accused of laundering $2.5 million through cryptocurrency for the network. 

Do Phi Khanh, Hoang Van Nguyen, Yun Song Guk, Hoang Minh Quang and York Louis Celestino Herrera were also sanctioned for their alleged roles in the DPRK IT worker networks.

The sanctions mean all US assets connected to those named are frozen and they can’t conduct any financial transactions or engage in business dealings with the US under threat of civil and criminal penalties.

Fraudulent tech workers with ties to North Korea have been highly active, targeting a range of industries, including blockchain companies. An April 2025 report by Google found that the schemes’ infrastructure has spread worldwide.

Worker fraud rings a growing threat: Chainalysis

OFAC’s sanctions included 21 cryptocurrency addresses across Ethereum and Tron. Chainalysis said on Thursday that the “designation of addresses across multiple blockchain networks reflects [North Korea’s] increasingly multi-chain approach to moving funds.”

Chainalysis added that North Korean IT worker schemes “represent a sophisticated and growing threat,” relying on stolen identities and fabricated personas to obtain employment with legitimate companies globally.

“Beyond generating revenue through fraudulent employment, these workers have also been known to covertly introduce malware into company networks to extract proprietary and sensitive information,” the firm said. 

“Cryptocurrency businesses should screen all counterparties against updated OFAC sanctions lists, be alert to patterns consistent with IT worker fraud, and monitor for unusual payment patterns.”
