Self Custody
Spark state-chain wallet with unilateral exit, maintaining strong user security with a seamless mobile experience.
Stacked Wallet
Your Bitcoin. In your control.
Save, send, and spend Bitcoin with a wallet you control. Built for New Zealanders who want simple, self-custodial Bitcoin: fast payments, low fees, and full control of your funds.
Lightning + On-chain
Use Lightning for fast, low-cost transfers and on-chain rails when moving long-term savings to cold storage.
Buy and Sell
Buy with NZD and sell back to NZD in a few taps, without address copy-paste friction.
Buying or selling a larger amount?
For bitcoin orders over NZ$200k, Stacked OTC gives you direct support from our team, lower all-in pricing for larger transactions, and managed settlement to or from your wallet.
Wallet Features
Buying, selling, stacking, saving and spending made simple.
Buying
Stack Bitcoin savings at your own pace directly from your Stacked account.
Selling
Move from Bitcoin to NZD quickly when you need liquidity.
Bitcoin Lightning
Fast, reliable, low-cost sending and receiving for everyday stacking.
On-chain
Send to your own cold storage whenever you choose.
Spend
Find and pay Bitcoin-friendly merchants with confidence.
Control
You stay in control, with unilateral exit available from Spark state-chain.
Privacy
Self-custody means Stacked doesn’t know your balance, who you pay, or who you receive from.
Keep more of every stack
Buying small amounts on-chain loses a slice of every stack to network fees — buys delivered over Lightning don't. Compare the two on a recurring buy and see, year by year, how much more of your money ends up as bitcoin.
