Why Bitcoin

Not on Bitcoin.
On Bitcoin.

21starter runs on Alkanes and subfrost, enabling token launches that execute and settle directly on Bitcoin L1. This is where Bitcoin-native capital forms.

Bitcoin settlement
Final on L1 requiring no bridging. Tap into the bitcoin ecosystem natively.
Alkanes Metaprotocol
IDO projects are built on smart contracts executed directly on Bitcoin's base layer, with no sidechain and no separate validator set.
subfrost BTCFi
Alkanes is powered by subfrost which is a way to use Bitcoin in DeFi without handing it to a company or leaving the Bitcoin blockchain.

Ready to launch?

If you're building something real on Bitcoin L1, apply for IDO.
We'll take it from there.
