SHx Expands Multi-Chain Accessibility with Uphold Listing

Stronghold, a payment infrastructure company bridging traditional finance and blockchain technology, has secured a listing for its native token SHx on Uphold, marking another step in the company's strategy to expand multi-chain accessibility for its growing user base.

The listing went live on November 27, 2025, at 3:00 PM UTC, enabling retail users to trade SHx on Uphold's platform. The development is notable for Uphold's support of tokens on both the Stellar and Ethereum networks—a feature that aligns with Stronghold's dual-chain approach to token distribution.

The Multi-Chain Strategy

Stronghold operates SHx natively on both Stellar and Ethereum blockchains through the SHx Bridge, which utilizes Axelar's infrastructure to enable one-to-one token movement between chains while maintaining total supply integrity. According to Stronghold, the company has capped SHx's total supply at 100 billion tokens.

The dual-chain architecture reflects different use cases: Stellar's network offers faster transaction speeds and lower costs, while Ethereum provides access to a broader decentralized finance ecosystem. Uphold's platform accommodates both implementations within a single interface.

Tammy Camp, CEO and co-founder of Stronghold, emphasized the platform selection reasoning, noting that Uphold provides support for both Stellar and Ethereum-based tokens—a relatively uncommon feature among major exchanges. Camp indicated the listing responded to requests from the community, which Stronghold reports numbers over 215,000 members globally.

Stronghold's Payment Infrastructure

Founded in 2015 and launched in 2017, Stronghold operates primarily as a payment and financial services platform built on the Stellar network. The company's service portfolio includes ACH payment processing, merchant financing through cash advances, point-of-sale checkout systems, and card processing capabilities.

The platform also offers StrongholdNET, a virtual payments network with APIs designed for developers building financial applications. Stronghold reports that thousands of merchants currently use this network.

SHx functions as the utility token within this ecosystem, with stated use cases including real-time settlements, discounted transaction fees, merchant rewards, governance participation, and liquidity provisioning in DeFi protocols. The token also plays a role in facilitating merchant cash advances through decentralized finance mechanisms.

Recent Momentum and Recognition

The Uphold listing follows several milestones for Stronghold in 2024 and 2025. The company appeared on the Forbes Fintech 50 list and ranked on the 2025 Inc. 5000 list of fastest-growing private companies. In terms of exchange access, SHx received its first U.S. exchange listing on Kraken prior to the Uphold announcement.

Additionally, Stronghold deployed what it describes as a 60 billion SHx smart contract escrow intended to support long-term ecosystem stability—representing 60% of the token's total fixed supply.

Token Contract Upgrade Requirement

Stronghold has communicated that holders of the ERC-20 version of SHx on Ethereum must upgrade their tokens to a new contract address before trading on Uphold or accessing certain Stronghold services. The company provides an upgrade portal at gateway.stronghold.co/upgrade.

The upgrade process requires two transactions: first approving the upgrade contract to access the old tokens, then executing the token swap. Stronghold has published detailed instructions for various wallet types, including MetaMask, Trust Wallet, Trezor, and SafePal.

The new ERC-20 contract address is listed as 0x516d31321928700C6B4fB0DB0c8c6BC5d6799787. Stronghold warns that tokens sent to services accepting only the new contract without upgrading may be at risk.

Leadership and Vision

Stronghold was co-founded by Tammy Camp and Sean Bennett. Camp brings a background in technology and finance entrepreneurship, while Bennett's experience spans software development and blockchain technology, focusing on the technical implementation of the SHx ecosystem.

The company positions itself as working toward a compliant, enterprise-grade payments infrastructure that bridges traditional and blockchain-based financial systems—a space that has seen growing interest as institutional players explore blockchain integration.

Regulatory and Compliance Positioning

Stronghold emphasizes Uphold's regulatory clarity and transparency as factors in the platform selection. The company's focus on compliance aligns with broader industry trends as cryptocurrency businesses navigate evolving regulatory frameworks globally.

The listing on Uphold—a platform that has operated with various regulatory licenses in different jurisdictions—may signal Stronghold's intent to maintain accessibility in markets with stricter cryptocurrency regulations.

Looking Ahead

For Stronghold, the Uphold listing represents an expansion of retail and developer access to SHx across both supported blockchain networks. The company's emphasis on cross-chain functionality and payment infrastructure positions it within a competitive landscape of projects attempting to solve interoperability and real-world utility challenges.

The requirement for ERC-20 token holders to upgrade their contracts before accessing new services highlights the ongoing technical maintenance involved in managing multi-chain token deployments. How smoothly this transition proceeds may influence user confidence in the platform's long-term technical stability.

As the cryptocurrency industry continues to mature, projects like Stronghold that focus on practical payment applications rather than purely speculative use cases represent one potential direction for blockchain technology adoption. Whether this approach gains traction will depend on merchant adoption rates, regulatory developments, and the platform's ability to compete with both traditional payment processors and other blockchain-based alternatives.

Users considering trading or upgrading SHx tokens should verify all contract addresses through official Stronghold channels and exercise caution with any unsolicited communications regarding token upgrades, as such transitions are common targets for phishing attempts.
