Ballet

Ballet is a consumer cryptocurrency cold-storage company founded by Bobby Lee that makes physical, non-electronic wallet cards based on the BIP38 open-source standard, letting people store Bitcoin, Ethereum, XRP and 1,000+ coins and NFTs safe from electronic hacking and preventable user error. The physical REAL Series card holds the keys; a companion mobile app, Ballet Crypto, lets holders check balances and market value and add assets. Backed by Ribbit Capital, Ballet is a hardware/consumer product rather than a developer platform, so it publishes no public API — this profile captures its identity, security posture, and open-source footprint.

Ballet is profiled on the APIs.io network. Tagged areas include Company, Crypto, Cryptocurrency, Wallet, and Cold Storage.

Ballet’s developer surface includes engineering blog and 5 more developer resources.
