Questions
Is this the same as dollar cost averaging (DCA)?
Yes. Buying a fixed amount of Bitcoin on a schedule is what people call dollar cost averaging, or DCA, and Stackk does it from a vault you own.
Can Stackk freeze or move my money?
No. The only thing we can do is pause or limit new buys, and withdrawals keep working either way.
How do I know I get a fair price?
Every buy is checked against Chainlink’s Bitcoin price. If nobody sells within 1.5% of it (you can change this), the buy is cancelled and your dollars go back to your vault.
Are there limits?
Yes, while we’re new each buy and each plan has a spending cap, and raising a cap takes 48 hours’ notice.
Is a Bitcoin token the same as real Bitcoin?
No. cbBTC is issued by Coinbase and WBTC is held by BitGo/BiT Global and bridged, so you’re trusting them to back it; real Bitcoin lives on the Bitcoin network.
What does “co-held with Bound” mean?
Real Bitcoin goes to a 2-of-2 wallet where you hold one key and Bound holds the other, so moving it needs both signatures and a network fee. Bound’s co-signing lasts three months per wallet and the app reminds you to renew, but what happens if Bound goes away hasn’t been confirmed in writing by SODAX or Bound yet.
Who holds my Bitcoin before it’s sent?
Your vault holds it as sodaBTC, a SODAX token on Sonic that SODAX can upgrade, until the batch goes out. Bitcoin tokens are sent after every buy, so nothing waits.
Which chains and tokens can I pay with?
Ethereum, Base, Arbitrum, BNB Chain, Polygon, Optimism, Avalanche, Sonic, Solana, Stellar, Sui, NEAR, Stacks and Injective. Pay with USDC, USDT, ETH, SOL, BNB or most other tokens on those chains. What you pay with is sold for USDC (a dollar coin) once when it arrives, and your vault buys Bitcoin from that.
Can I pay from Binance, Kraken or Coinbase?
Yes: withdraw USDC to your own wallet and top up from there. Kraken can also send USDC on the Sonic network straight to your vault once it’s set up.
What if a buy doesn’t go through?
After 10 minutes the dollars go back to your vault and that buy is skipped; your vault never buys twice to catch up.
What if Stackk shuts down?
Your vault doesn’t need us: anyone can run the scheduler, and you can always withdraw. EVM wallets withdraw with one Sonic transaction; Solana, Stellar and other wallets go through SODAX’s relay, so if that’s down your vault waits until it’s back.
I use Solana, Stellar, Sui, NEAR, Stacks or Injective. Anything different?
Your wallet controls the vault through a SODAX account on Sonic, which SODAX can upgrade. The most that account could do is buy within your limits or send money to your own wallet or your delivery addresses.
Do I need gas on Sonic?
Not with an EVM wallet: you sign, and our relayer sends it for you. Other wallets pay their own chain’s normal fee.
Is it audited or insured?
Not audited yet: an independent review is scheduled before launch. Nothing is insured.
