What Stronghold does
Stronghold is a San Francisco-based fintech company founded in 2017 that builds API-first virtual payment networks and blockchain-based payment infrastructure on the Stellar network. The company offers a modular platform spanning ACH Payments, Stronghold Direct, Checkout, Card Processing, Real Time Payments, Merchant Financing, and Virtual Payment Networks, all accessible through public Developer APIs with JavaScript SDK support. Its proprietary SHx token, built on Stellar using Stellar Consensus Protocol with Proof-of-Agreement consensus, consumes 0.1731 watt-hours per transaction and serves as the native currency for merchant rewards, fee discounts, governance voting, and liquidity provision within the Stronghold ecosystem.
The company serves SMBs seeking modern payment infrastructure, developers embedding payments into their products, enterprise clients such as IBM requiring customized blockchain-based payment solutions, and digital asset enthusiasts using the SHx token. The platform bridges legacy banking rails with Web3 infrastructure, enabling payments to clear and settle in seconds rather than days and supporting micropayments at the network level. StrongholdNET, the overarching ecosystem, integrates over 100 businesses, while token distribution is achieved through listings on major exchanges including Kraken, KuCoin, BitMart, Gate.io, and Bittrex Global, and wallet integrations with Freighter, Ledger, and Lobstr.
Revenue mechanics span transaction fees on payment processing, interest from merchant financing (capitalized via SHx liquidity pools), and token-related economics including merchant rewards and fee offsets. Stronghold also operates Stronghold Capital, a $100 million investment fund deploying SHx into ecosystem companies over a five-year horizon. The company is led by co-founders Tammy Camp (CEO) and Sean Bennett (CTO), and recently acquired 20022 Labs in May 2024 to embed ISO 20022 financial messaging standard capabilities into its payment network.

Stronghold competitors and assessment
Company assessmentDirect peers
- MoonPay: MoonPay provides crypto on/off-ramps and embedded payment APIs for apps and merchants. It overlaps directly with Stronghold's ACH/crypto on-ramp functionality and developer API focus.
- Alchemy Pay: Alchemy Pay is a crypto-fiat payment gateway operating in 200+ countries, providing on/off-ramps, cards, and checkout. It is directly comparable to Stronghold's ACH + crypto + real-time merchant payment offering.
- BitPay: BitPay is one of the largest crypto payment processors, enabling merchants to accept and settle in crypto or fiat. Like Stronghold, it offers merchant tools (checkout, invoicing, APIs) and bridges crypto with traditional payment rails for SMBs and enterprise.
- Flexa: Flexa is a pure-play digital payments network enabling merchants to accept crypto at the point of sale. It is one of the closest direct parallels to StrongholdNET's virtual payment network concept for crypto-native acceptance.
- Circle: Circle issues USDC and operates payment, settlement, and treasury APIs for businesses. Stronghold competes head-on with Circle's stablecoin-based merchant and cross-border payment products, and both target enterprise treasury and embedded-finance use cases.
- Coinbase Commerce: Coinbase Commerce provides crypto payment gateway APIs, checkout, and invoicing for merchants and developers. It is the most direct US-headquartered competitor to Stronghold on merchant crypto acceptance and developer-first tooling.
- Wyre: Wyre (now part of Prime Trust / previously independent) offered crypto on/off-ramp and payment infrastructure APIs for developers and merchants — closely aligned with Stronghold's API-first payment and merchant financing product.
- Ripple: Ripple offers blockchain-based cross-border payments (RippleNet, On-Demand Liquidity) and enterprise payment infrastructure. It is highly comparable to StrongholdNET's cross-border and real-time settlement positioning, particularly for banks and financial institutions.
Broad incumbents
- Stripe: Stripe is the dominant developer-first payment processor with global ACH, card, real-time, and emerging crypto capabilities. While it serves a much broader market, its API-first model and SMB targeting are the most direct incumbent reference for Stronghold's core product.
- Plaid: Plaid provides financial data connectivity and payment-rail infrastructure (including account funding and auth) used by fintechs and developers. It is a broad incumbent comparable to Stronghold on developer-first payments infrastructure and embedded-finance rails.
