Strongkeep

Strongkeep is a cryptocurrency infrastructure company that enables financial institutions and digital asset businesses to access leading cryptocurrencies through a unified API. Its services range from hot wallets and co-signing solutions to institutional-grade cold storage and digital asset custody, while abstracting network upgrades, forks, and maintenance.

The logo design I created for Strongkeep combines the letter S with a shield and the battlements of a fortress, representing security, protection, reliability, and trust. Its bold, geometric form and restrained monochrome palette reflect strength and stability while creating a modern identity suited to both emerging fintech companies and established financial institutions.
