Fees and value for zkSync Era to Bitcoin
SatoshiSpace uses a tiered fee schedule baked into the rate. Under 5 000 USD the fee is 2.5 percent, 5 000 to 50 000 USD is 1.75 percent, and 50 000 USD and above is 1.0 percent. This is competitive versus the common 0.5 to 3 percent fees on centralized exchanges with KYC plus withdrawal fees. SatoshiSpace keeps the process private and custody free while offering straightforward, predictable costs.
Safety and privacy baked into every transfer
SatoshiSpace operates without accounts or KYC so you never reveal identity. Deposits are processed with deposit and forget UX, and we monitor mempools to protect against front running and related risks. You stay in control of your funds with no wallet connection required, and you receive the converted asset directly to your destination address.
Withdrawal and finality times
On the source chain confirmations occur at the typical zkSync Era speeds, with fast finality for ETH based transfers. BTC withdrawals depend on Bitcoin network conditions, usually final within a short window after the bridge burn, enabling timely access to BTC for savings or payments.
SatoshiSpace versus central exchanges and other bridges
Unlike centralized exchanges that require KYC and custody, SatoshiSpace never asks for your identity and never holds your funds. Wrapped tokens on other bridges pose custodial risk, while older cross chain bridges may require more complex flows. SatoshiSpaces privacy first model is ideal for the zkSync Era to Bitcoin use case, offering a simple, no KYC, no wallet, deposit and receive experience that keeps you in control of your assets. When you compare to Stargate, Across, Synapse, Wormhole, or deBridge, SatoshiSpace stays focused on privacy and ease of use for this specific pair.
