Three fortunate coincidences collaborated to shape Francisco Paradaltas into an outstanding reformer in monetary matters: the first was his personality and family circumstances; the second was his experience of modernity, of knowledge of technological and scientific advances obtained in France; the third was the receptive and dynamic context of Barcelona in the first Industrial Revolution.

In the theoretical scope, he was converted into a passionate publicist on coinage reform, the modernization of its production and the usefulness of the Barcelona mint. In that sense, he published a pair of books and left an unpublished manuscript, now recovered, along with numerous principals for guidance in the processes to which they pertained.

In practice, he showed himself to be tenacious in the introduction and implementation of methods for converting old-time mints into modern money factories. Among his successes in this field, the construction in Barcelona of mechanical coin presses operated by steam power stands out, as well as does the application of different methods for optimizing the refinement and ductability of precious metals.

Paradaltas' career in the public sector brought him to serve as a member of the board of the Junta de Moneda (Coinage Council) and as director of the mints of Barcelona, Segovia and Madrid. In this latter, at the zenith of his career, he saw his intense desires for reform frustrated, and upon being relegated to the mint of Sevilla, he retired from public life.
