- Keeping your SHx safe When you hold crypto, the biggest risk stems from how you store the private keys that control your funds, and wallet design makes a major difference here. A hot wallet stays connected to the internet, convenient for quick transactions, but it also expands the attack surface. Malware, phishing sites, compromised apps, or remote exploits all become realistic threats because the private key is accessible to software that can reach the network. A cold wallet keeps the private key completely offline, so the key never touches an internet-connected device during normal use. This isolation eliminates most remote attack paths. An attacker would need physical access to the device itself, which is a much higher bar. The SHx card builds on standard cold storage and further simplifies it. Instead of generating and demanding that you back up with a traditional seed phrase, the card is designed so that the private key is created and stored only on its secure chip by default. This removes one of the most common points of failure in crypto security (the seed phrase itself) while still keeping the key fully offline. How the SHx card works The Tangem x Stronghold cards are battery-free NFC hardware wallets built around a Common Criteria EAL6+ certified secure element chip. In the default (seedless) mode, the private key is generated entirely inside the chip using its hardware True Random Number Generator (certified BSI PTG.2 / AIS 31). The TRNG draws entropy from physical noise (thermal, electronic, oscillator jitter), conditions it to remove bias, extracts 256 bits, validates it against the curve order, and uses it directly as the master private key; no seed phrase is ever created. The key stays in the chip forever and only ever outputs signatures. In the optional seed-phrase mode The app can generate a standard BIP-39 phrase (12/24 words) using the phone’s secure random generators if you want cross-wallet compatibility. This seed phrase is imported into the card’s chip and wiped from the phone’s memory. It also supports a passphrase for additional entropy. Backup: The private key is securely cloned to one or two additional cards over an encrypted, mutually authenticated channel. Tangem’s firmware has been independently audited by Kudelski Security and Riscure, its mobile app was reviewed by Cure53, and the cards themselves carry an IP69K certification for maximum dust and high-pressure water resistance. Best practices for your SHx card 1. Understand your backup system
Los pagos transfronterizos enfrentan un problema de comisiones. Una sola transferencia puede perder una parte significativa de su valor debido a intermediarios, conversiones de divisas y sistemas de liquidación lentos. Stronghold creó su plataforma para cerrar esa brecha; funciona sobre la red Stellar y utiliza el token SHx para impulsar liquidaciones rápidas y de bajo costo, permitiendo que el valor cruce fronteras sin los peajes habituales.
Una vez que tienes SHx, necesitas una solución de gestión que iguale la seguridad de la red. La billetera SHx de Stronghold y Tangem es la opción ideal para esto. Con ella, tu clave privada permanece completamente fuera de línea y nunca toca internet. Además, con varias tarjetas en un mismo set, puedes optar por no gestionar frases semilla.
Esta guía explica cómo funciona la tarjeta SHx a nivel técnico y te muestra las mejores prácticas para mantener tu SHx seguro a largo plazo.
¿Qué es Stronghold y el token SHx?
Stronghold es una empresa de pagos y servicios financieros fundada en 2017. En 2018, lanzó su propia stablecoin, Stronghold USD, un token vinculado al dólar estadounidense. Stronghold se asoció con IBM para ayudar a instituciones financieras a mover dinero más rápido, a menor costo y con mayor seguridad. Luego, la empresa se enfocó en pagos domésticos, ayudando a negocios que dependen del efectivo a aceptar transacciones digitales por primera vez.
El token SHx impulsa gran parte de esta infraestructura. Existe de forma nativa en Stellar, una red diseñada para pagos y transferencias internacionales, y también en Ethereum, con puentes que conectan ambas a Solana y XRPL. En las cuatro redes, SHx mantiene un suministro fijo de 100 mil millones de tokens, utilizados para liquidaciones en tiempo real, comisiones de transacción con descuento y votaciones de gobernanza. Actualmente, Stronghold desarrolla infraestructura de pagos que conecta los sistemas financieros tradicionales con blockchain, incluyendo pagos ACH, liquidación en tiempo real, financiamiento a comercios, sistemas de cobro y procesamiento de tarjetas.
Tokenomics de SHx (Stronghold)
SHx se posiciona como un token utilitario dentro del ecosistema de pagos y financiamiento de Stronghold, no como un activo puramente especulativo.
- Maximum supply: 100 mil millones de SHx (fijo; no aumentará).
- Total supply: ~99.75 mil millones.
- Circulating supply: Aproximadamente 17.7–18.2 mil millones (cifras de mediados de 2026 reportadas por Stronghold y principales rastreadores).
Nativo en Stellar. También disponible/puenteado a Ethereum (ERC-20), Solana y XRP Ledger. Divisible hasta 7 decimales.
Gestión del suministro (escalera de escrow)
En 2025, Stronghold bloqueó 60 mil millones de SHx en 60 cuentas de escrow separadas (1 mil millón cada una) usando contratos inteligentes Soroban de Stellar.
- Los desbloqueos ocurren el día 15 de cada mes en un ciclo escalonado de 60 meses.
- Any unused portion of a monthly unlock automatically relocks for another 5 years. This creates a rolling ladder that releases only what is needed and avoids large, sudden supply shocks. Utility Rewards
Utilidad
Rewards: Comerciantes y clientes ganan SHx según el volumen de transacciones en la red de pagos de Stronghold.
Merchant financing: Los pools de liquidez de SHx respaldan el producto de préstamos de Stronghold.
Fee benefits: Puede usarse para reducir los costos de procesamiento.
Governance: Los holders votan sobre funciones y cambios de reglas en la red. Un token completo = un voto (los saldos fraccionarios no cuentan). Requisitos de quórum: 1% del suministro circulante activo para propuestas normales; 25% para enmiendas a las reglas de gobernanza.
Existen mecanismos deflacionarios limitados (por ejemplo, quema de una parte de ciertas comisiones relacionadas con financiamiento).
Los detalles oficiales están disponibles en stronghold.co/shx y en la documentación de gobernanza del proyecto.

Best practices for your SHx card 1. Understand your backup system
Each SHx set includes three cards. Every card holds a complete, independent copy of your private key. Losing one card does not put your funds at risk; the remaining cards still contain the full key, protected by the chip. 2. Store your backup cards separately
Keep the cards in different physical locations. Storing them all together creates a single point of failure; theft, fire, or flood could wipe out the entire set. Treat each card like a separate physical key. Note that two cards together also allow you to reset the access code, so plan storage with that recovery option in mind. 3. Set a strong access code
Add an access code during setup. This adds a second layer of protection beyond simply possessing the card. Choose a strong, random code so a lost or stolen card is far less useful to anyone who finds it. 4. Know the recovery limits
La autocustodia tiene un límite claro. Si todas las tarjetas del set se pierden o destruyen y no configuraste una copia de seguridad con frase semilla, el acceso a los fondos se pierde de forma permanente. Ningún equipo de soporte, restablecimiento de contraseña ni servicio de recuperación podrá restaurarlo. Este es el compromiso de la verdadera autocustodia: ningún tercero puede ayudarte, pero tampoco puede tocar tus fondos.
Con la tarjeta SHx, tienes control total sobre tus fondos. Ningún banco, exchange o tercero puede congelarlos, confiscarlos o perderlos por ti. Este nivel de independencia también implica que la responsabilidad es tuya.
