Commissions: 10% revenue share.
Ledger pays a 10% commission for sales of their 2 hardware wallets. These are priced at about $60 and $120 (according to my quick and dirty currency calculations).
Ledger is a relatively big company with over 140 employees. Their website is very popular. I would suggest that they offer one of the most popular crypto hardware wallet solutions out there.
Unfortunately, they do not pay very high commission rates. Their competitor, Trezor, pays affiliates a 20% – 50% higher revenue share rate.
