The privacy cost for STRK20 is fixed at 4 STRK, regardless of transaction size. @Starknet @KaitoAI When executing a private transaction with strkBTC, the cost required by STRK20 is currently 4 STRK. This amount does not increase based on the transaction value—whether you’re transferring $70 or $7,000, the fee remains 4 STRK. STRK20 represents shielded balances as encrypted notes within a note-based privacy pool. When a private transfer occurs, an existing note is consumed and a new note is created; Starknet verifies ownership, double-spending, and input-output balance consistency using a zero-knowledge proof—without revealing the sender, receiver, or amount. The fixed cost creates entirely different economics depending on usage scale. Paying the same 4 STRK for a $70 transfer versus a $7,000 transfer results in a 100-fold difference in relative cost burden. While the dollar value of this fee fluctuates with STRK’s price, the 4 STRK fee does not scale upward simply because the transferred amount is larger. As a result, users who frequently move small amounts and those who rarely move large amounts experience the same fee schedule very differently. How often you use privacy features and how much you transfer at once directly impact your actual cumulative costs. The scope of what private transfers conceal is also specific: Public observers can see the encrypted note and necessary protocol metadata, but cannot see the sender, receiver, amount, or which private balance was used. Throughout this process, zero-knowledge proof generation and on-chain verification occur simultaneously. When evaluating strkBTC’s usability, this per-transaction economics model—alongside APY and bridge pathways—makes a significant difference. What matters more to real user experience isn’t merely the availability of privacy, but how its costs accumulate with repeated use. #strkBTC #STRK20
