According to The Block, crypto hardware wallet provider Ledger has signed an "exclusive" partnership with Sotheby's to provide wallets to Sotheby's top NFT collectors. The free service is for one year. Ledger said that as part of the cooperation, the winner of the Sotheby's NFT auction will receive a limited edition co-branded Ledger x Sotheby's Nano X wallet, and plans to expand the product to Ledger Stax in the future. Ledger will also provide services to Sotheby's customers to help them understand the self-custody issues of digital assets.
