Solidity es el lenguaje de contrato inteligente para la Ethereum Virtual Machine (EVM). Con él codificamos lógica descentralizada que gestiona activos, identidades y procesos de negocio de forma inmutable y transparente.
¿Por qué Solidity?
Estándar de facto
Soporta ERC‑20, ERC‑721 y la mayoría de protocolos DeFi.
Seguridad auditada
Herramientas maduras de análisis estático y fuzzing.
Comunidad activa
Más de 400 k desarrolladores y 1 700 repositorios open‑source.
Del concepto al mainnet
1. Modelado funcional
Definición de actores, flujos y tokenomics.
2. Desarrollo local
Hardhat / Foundry con pruebas unitarias en JS/TS.
3. Seguridad
Análisis estático (Slither), fuzzing (Echidna) y revisión manual.
4. Testnet
Deploy en Goerli / Sepolia y auditoría pública.
5. Mainnet & monitorización
Liberación con multisig, métricas on‑chain y alertas.
Conceptos esenciales
onlyOwner, roles (OpenZeppelin) y patrones pull‑over‑push.Herramientas del ecosistema
| Propósito | Herramienta | Notas |
|---|---|---|
| Framework | Hardhat | Pluginable, soporte TypeScript |
| TesGeo | Foundry | Muy rápido, fuzzing nativo |
| Auditoría | Slither | Análisis estático |
| Fuzzing | Echidna | Propiedad basada |
| Upgrades | OpenZeppelin SDK | Proxies y scripts |

Construyendo sobre la EVM
Participamos en el estándar ERC‑4337 (Account Abstraction) y contribuimos a librerías OpenZeppelin.
Buenas prácticas críticas
- • Bloquea compilador (
pragma solidity ^0.8.x) para evitar ataques de pragma‑downgrade. - • Evita bucles sin límite y arrays dinámicos en storage.
- • Usa librerías seguras (SafeMath integrado en ≥0.8).
- • Implementa pause y upgrade‑timelock.
- • Audita terceros; recompila bytecode verificado en Etherscan.
Solidity is the smart contract language for the Ethereum Virtual Machine (EVM). With it, we code decentralized logic that manages assets, identities, and business processes in an immutable and transparent way.
Why Solidity?
De facto standard
Supports ERC‑20, ERC‑721 and most DeFi protocols.
Audited security
Mature static analysis and fuzzing tools.
Active community
Over 400k developers and 1,700 open-source repositories.
From concept to mainnet
1. Functional modeling
Definition of actors, flows and tokenomics.
2. Local development
Hardhat / Foundry with JS/TS unit tests.
3. Security
Static analysis (Slither), fuzzing (Echidna) and manual review.
4. Testnet
Deploy on Goerli / Sepolia and public audit.
5. Mainnet & monitoring
Release with multisig, on-chain metrics and alerts.
Essential concepts
onlyOwner, roles (OpenZeppelin) and pull-over-push patterns.Ecosystem tools
| Purpose | Tool | Notes |
|---|---|---|
| Framework | Hardhat | Pluginable, TypeScript support |
| TestGeo | Foundry | Very fast, native fuzzing |
| Audit | Slither | Static analysis |
| Fuzzing | Echidna | Property based |
| Upgrades | OpenZeppelin SDK | Proxies and scripts |

Building on the EVM
We participate in the ERC‑4337 (Account Abstraction) standard and contribute to OpenZeppelin libraries.
Critical best practices
- • Lock compiler (
pragma solidity ^0.8.x) to avoid pragma-downgrade attacks. - • Avoid unlimited loops and dynamic arrays in storage.
- • Use safe libraries (SafeMath integrated in ≥0.8).
- • Implement pause and upgrade-timelock.
- • Audit third parties; recompile verified bytecode on Etherscan.
