ETZ-Swap is a non-custodial instant crypto swap service that aggregates liquidity across multiple venues to offer best-rate swaps between more than one hundred cryptocurrencies. Unlike an order-book exchange it never asks you to open an account, deposit collateral, or prove your identity — you pick the asset you are sending, the asset you want to receive, paste your destination wallet address, and the service routes the trade through its liquidity network and settles the output on-chain to the address you supplied.

From a notokyc.com perspective ETZ-Swap is not a third-party embed — it is the engine behind our first-party swap widget. The integration runs through EtzSwapService in our own application, which means we fetch supported coins, preview rates and execution quotes directly from the ETZ-Swap API, present them inside our own UI, and submit the user’s swap with their own wallet address as the payout destination. We have full first-hand visibility into how the service behaves under load.

For users who want the convenience of an instant swap without any of the surveillance baggage of a centralised exchange, ETZ-Swap sits in the same category as SimpleSwap, ChangeNow and StealthEx, and our day-to-day experience routing traffic through it has been consistently strong.

• Unlicensed by design. As a non-custodial aggregator ETZ-Swap does not sit under a traditional exchange regulator. That is consistent with every peer in the category (SimpleSwap, ChangeNow, StealthEx) but it is a deliberate trade-off and worth stating plainly.
• No fiat on-ramp. You must already hold crypto to use the service. ETZ-Swap is not where you turn a debit card into Bitcoin — it is where you turn Bitcoin into something else.
• Floating-rate execution risk. Floating rate gets you the best price at settlement time but the rate can shift between quote and on-chain confirmation. For tight-margin swaps the fixed-rate mode is the safer default even at a slightly higher fee.

ETZ-Swap’s pricing model has three layers and nothing more. First, the service fee — 1.2% on floating-rate swaps, 2% on fixed-rate swaps — is baked into the quoted exchange rate you see before you confirm. Second, the liquidity spread from the underlying venues the aggregator is routing against, which ETZ-Swap absorbs into the quote rather than charging separately. Third, the unavoidable on-chain network fees for the sending and receiving chains, also shown up front.

Crucially there are no deposit fees, no withdrawal fees, no account fees, no inactivity fees, and no fiat conversion fees. The rate you see at quote time is the rate you settle at in fixed mode, and the rate at execution time in floating mode.

A fixed-rate swap locks the exchange rate at the moment you request the quote. Whatever the market does between you sending the input asset and ETZ-Swap settling the output, you still receive the exact amount quoted at the start. This is the right mode for any swap where the output amount matters more than squeezing every last basis point — paying an invoice, topping up a casino balance, bridging a specific amount to another chain.

The service fee for fixed-rate mode is 2%, priced into the quoted rate rather than charged separately. The small premium over floating-rate mode is the price of certainty: you are paying the aggregator to eat the execution risk so you don’t have to.

Floating-rate swaps settle at whatever the aggregated market rate is at the moment your input transaction is confirmed on-chain. The quote you see at the start is indicative — if the market moves in your favour between submission and confirmation, you receive more; if it moves against you, you receive less. Over a large number of swaps this averages out close to the mid-market rate and typically beats the fixed-rate mode by the fee differential.

The service fee drops to 1.2%, making this the default choice for users who are comfortable with a small amount of short-term price variance. For fast chains — Solana, Tron, Litecoin — the window of variance is usually a minute or two, so the risk is genuinely minimal.

ETZ-Swap supports more than one hundred cryptocurrencies spanning every major chain a user is likely to touch. The Layer-1 coverage includes Bitcoin, Ethereum, Solana, Tron, BNB Chain, Polygon, Avalanche, Cosmos, Polkadot, Litecoin, Dogecoin, Bitcoin Cash, TON, NEAR and Cardano. Privacy coins are fully supported, including Monero (XMR) for users who want on-chain untraceability on either leg of the swap.

On the stablecoin side you get USDT and USDC on every chain they are deployed on — ERC-20, TRC-20, BEP-20, SPL, and Polygon — plus DAI and a handful of smaller issuers. Token coverage on Ethereum extends well past blue-chips: ERC-20 long-tail assets are routed through the aggregated DEX leg where venue liquidity allows. L2 support includes Arbitrum and Optimism natively, without a manual bridge step from the user’s side.

The single most important thing to understand about ETZ-Swap’s security posture is that there is nothing to hack into on your behalf. You never create an account. You never deposit funds to a wallet the service controls on a long-term basis. The service generates a single-use deposit address, you send to it, and your output asset is broadcast on-chain to the destination wallet you supplied in the same request. Start to finish, ETZ-Swap is a routing layer between your sending wallet and your receiving wallet — it does not maintain a user balance for you to lose.

Because there is no account there is no KYC database, no password to phish, no 2FA code to intercept, and no customer-support social-engineering vector targeting your login. For standard swap sizes — which covers essentially every retail user — the identity leakage surface is limited to the two wallet addresses visible on-chain to anyone anyway.

On the liquidity side the aggregator model removes single-venue risk: if one underlying liquidity source is degraded or offline, the router falls back to the next best path rather than failing the swap. Rate locks on fixed-rate mode are honoured by ETZ-Swap absorbing any short-term slippage, giving users deterministic settlement even in volatile market conditions.

ETZ-Swap is at its best in scenarios where opening another exchange account is either overkill or actively undesirable. Funding a no-KYC casino is the most common use case on notokyc.com — swap from whatever you already hold into whatever the operator prefers (often USDT on TRC-20 for cheap, fast transfers) and send straight to the deposit address in a single wallet-to-wallet flow.

Cross-chain bridging is another strong fit: swap USDC on Ethereum to USDC on Solana without ever touching a dedicated bridge UI or worrying about which bridge has been exploited this month. Consolidating dust across chains — a little ETH, some SOL, a bit of MATIC — into a single asset in a single wallet is essentially frictionless. And for privacy-sensitive swaps (BTC to XMR, or XMR to BTC) the non-custodial, no-account model keeps the metadata trail to an absolute minimum.

ETZ-Swap is the right tool for anyone who already holds crypto and needs to move between assets or chains without opening another exchange account. The non-custodial, no-KYC, wallet-to-wallet model is simply a better fit for that workflow than a centralised venue, and the fee structure — 1.2% floating or 2% fixed — is competitive with the rest of the aggregator category.

It is not the right tool for fiat on-ramping, long-term custody, or order-book trading. If you need to turn a debit card into Bitcoin, open an exchange account; if you want to leave a balance on the platform, open an exchange account; if you want to place a limit order, open an exchange account. For everything else — cross-chain swaps, casino funding, dust consolidation, privacy-sensitive routing — ETZ-Swap is as close to a frictionless default as this category gets, and the fact that it powers our own first-party widget on notokyc.com is the strongest signal we can give about how much we trust it in production.
