The Silicon Group of Companies, which named Masadur as its brand ambassador, will sponsor his entire Palk Strait expedition.
The event saw Masudur Rahaman enter the water once again after eight years in his effort to get back to shape before his new venture.
Bengali musical band Jowar paid tribute to the ace swimmer by rendering two of their compositions on him.
Masadur had earlier declared that he would attempt to cross the Palk Strait last year itself, but dearth of sponsors delayed his plan.
The swimmer had created a sensation in 1997 by crossing the English Channel before successfully traversing the Strait of Gibraltar in 2001.
