Overview

BetKarma — KYC-Never Crypto Exchange, Mixer, Tor and SimpleX

Details

BetKarma is a privacy-focused, registration-free cryptocurrency exchange and mixer supporting Bitcoin, Monero, Ethereum, Zcash, Litecoin, Solana, BNB, TRX, and USDT/USDC across multiple networks. The service offers several types of exchange routes without forcing users to browse a long list of individual pairs. These include BTC and USDT same-asset mixing, private purchase and sale of Monero, conversion into BTC or ETH, and withdrawals into supported stablecoins. Shielded Zcash deposits using Unified Addresses or Sapling zs1 addresses can be exchanged for XMR, BTC, or USDT. Transparent Zcash deposit addresses are not accepted on shielded routes. BetKarma follows an explicit KYC-never policy. We do not request identity documents, selfies, biometric data, proof of address, source-of-funds statements, or source-of-wealth information. We do not conduct AML screening and do not use blockchain analytics, transaction-surveillance systems, or surprise KYC procedures presented as additional verification. Privacy is reinforced by the settlement architecture. Incoming customer coins are never forwarded directly to the recipient address. A deposit is accepted for execution of the order, while the corresponding payout is sent separately from BetKarma’s internal reserve. As a result, the specific deposit and payout do not form a direct on-chain bridge. Every exchange order includes a Bitcoin-signed Letter of Guarantee in the standard Bitcoin Signed Message format using BIP-137. The letter records the immutable direction, rate, amounts, deposit address, recipient address, and expiry conditions of the order. Its signature can be verified independently in a compatible Bitcoin wallet or through the public verifier, without relying on the BetKarma interface. Shielded Zcash orders additionally provide signed deposit and completion receipts. The exchange is available through three privacy levels: 1) A regular clearnet website with a convenient live exchange interface. 2) A dedicated text-only .onion terminal for Tor with no JavaScript, cookies, images, accounts, or external resources. 3) An operator-assisted SimpleX route using a one-time invitation link or QR code. Exchange details are agreed through an end-to-end encrypted SimpleX conversation, so recipient and refund addresses do not need to be entered on the website. Support tickets are encrypted at rest and removed according to the post-closure retention policy. The current service fee, minimum, maximum, available reserve, required confirmations, and estimated processing time are displayed for each direction before an order is created. Once the order is confirmed, its rate and exact send and receive amounts are locked. Deposits must become visible on-chain before the deadline shown on the order, after which the service waits for the required network confirmations and completes the payout.
