Question 1

What is K Khay?

Accepted Answer

K Khay is a non-custodial cryptocurrency payment gateway and sovereign financial operating system. It enables global businesses to accept 500+ cryptocurrencies across 190+ blockchains directly into self-custody cold wallets with 0.5% flat fees, and allows individuals to send instant zero-fee P2P transfers using biometric passkeys.

Question 2

Which blockchains and tokens does K Khay Gateway support?

Accepted Answer

K Khay Gateway supports over 500+ cryptocurrencies across 190+ blockchains. This includes major EVM networks (Arbitrum, Base, Polygon, BNB Smart Chain, Ethereum, Avalanche, Optimism) as well as native non-EVM chains including Bitcoin (BTC), Solana (SOL), The Open Network (TON), Dogecoin (DOGE), TRON (TRX), and Litecoin (LTC).

Question 3

Can I accept Bitcoin (BTC), Solana (SOL), TON, and Dogecoin (DOGE)?

Accepted Answer

Yes. In addition to multi-chain EVM tokens, K Khay natively routes and settles native Bitcoin (BTC), Solana (SOL), The Open Network (TON), and Dogecoin (DOGE) directly to your self-custody wallet addresses with real-time confirmation tracking.

Question 4

How does the non-custodial payment gateway work?

Accepted Answer

When a customer pays an invoice, funds are routed through verified on-chain smart contracts or swept from unique deterministic deposit addresses. 99.5% of the payment settles directly into the merchant's configured payout address in the same atomic transaction, while 0.5% is routed to the protocol treasury. K Khay never holds, custodies, or freezes merchant funds.

Question 5

Does K Khay hold rolling reserves or delay payouts?

Accepted Answer

No. Unlike traditional payment processors (like Stripe or PayPal) that hold 5% to 10% in rolling reserves for up to 180 days, K Khay enforces zero rolling reserves. Settlements are confirmed on-chain in seconds and are immediately available in the merchant's self-custody address.

Question 6

Who pays the gas fee when sweeping customer payments?

Accepted Answer

K Khay sponsors the gateway gas fees required to sweep and settle customer deposits on supported networks. Merchants pay $0 in gas to receive and settle funds into their cold storage.

Question 7

How fast do merchant settlements arrive in cold storage?

Accepted Answer

Settlements are instantaneous and autonomous. Once an on-chain transaction is confirmed on the network (typically 1–3 seconds on EVM and Solana), K Khay routes the 99.5% payout directly into your self-custody cold storage or personal payout address in the exact same block.

Question 8

Are there transaction fees on K Khay Pay transfers?

Accepted Answer

No. Peer-to-peer transfers between registered K Khay users on K Khay Pay carry 0% transaction fees with sub-second settlement using @username handles.

Question 9

How do biometric passkeys secure K Khay Pay?

Accepted Answer

K Khay utilizes the FIDO2 / WebAuthn standard (Apple Touch ID, Face ID, Windows Hello, and YubiKeys). Biometric templates remain securely inside the device's isolated hardware enclave (Secure Enclave / Titan M). No vulnerable seed phrases can be lost or phished.
