# Vauld > Vauld is a crypto asset management platform (formerly Bank of Hodlers), founded in India and headquartered in Singapore, offering crypto lending, borrowing, and fiat<>crypto trading. Its Enterprise API exposes wallets, INR fiat rails, KYC, crypto swaps, borrowing, and lending to partner organisations, authenticated with HMAC-SHA256 request signing. Vauld suspended withdrawals in July 2022 and has been in creditor-protection restructuring; the API documentation remains published and the platform API still responds, but the documented testnet hosts no longer resolve.
