Change now is a non-custodial swap service for 1000+ crypto assets

Change now is a non-custodial crypto exchange built for instant swaps, fiat purchases, and wallet-to-wallet asset conversion across more than 1000 cryptocurrencies. It is best known for simple exchange flows: choose a pair, enter a receiving address, send the deposit, and receive the target coin without creating a trading order book position. Fixed-rate mode locks the agreed output amount during market movement, while floating-rate swaps follow the live market rate.

The exchange flow behind a simple swap

A swap starts with a currency pair, such as BTC to ETH, SOL to USDT, or XRP to ADA. The interface estimates the output, shows whether the rate is fixed or floating, and generates a deposit address for the asset being sent. After the deposit reaches the required network confirmation state, the service exchanges the funds through its liquidity routing and sends the new asset to the destination address.

That workflow matters because many users arrive with one clear task: move from one coin into another without learning a full trading terminal. Change now reduces the operation to the fields that matter for execution: asset, amount, receiving address, rate mode, and deposit transaction. The user still pays blockchain network fees, and the quoted exchange includes the service-side pricing shown at the time of the swap.

Fixed-rate mode and floating-rate mode serve different jobs

Fixed-rate mode is the cleaner choice when the received amount matters more than chasing a slightly better market tick. Once selected, the quoted output is the amount the swap is designed to deliver if the deposit arrives within the stated window and matches the transaction details. It is useful during volatile Bitcoin, Ethereum, meme coin, and DeFi token moves because the user sees a clear destination amount before sending funds.

Floating-rate mode tracks the live market price until the exchange executes. It suits users who accept price movement and want a route based on the current estimated rate. Change now presents both modes as part of the exchange decision rather than burying them in advanced settings, which keeps the swap flow understandable for someone moving between wallets, networks, or portfolio positions.

Where the 1000+ asset catalog matters

The large asset list is the main reason the service fits more than Bitcoin and Ethereum conversions. It supports established coins, stablecoins, DeFi assets, meme coins, and tokens from major ecosystems, making it useful when a wallet holds a coin that is awkward to trade on a local fiat exchange. The official interface also refers to more than 1 million supported currency pairs, which reflects how many asset combinations appear when many coins are available on both sides of a swap.

That breadth helps with practical conversions: turning mined coins into a stablecoin, moving a long-held token into ETH for gas planning, switching between USDT network versions where supported, or receiving an asset that a preferred wallet handles more cleanly. Change now is strongest when the user already knows the asset they want and needs a direct path to it.

Buying crypto with fiat fits the same entry point

The service also includes buy-and-sell flows for people starting with a bank card or another fiat payment route. The purchase experience differs from a crypto-to-crypto swap because payment partners, region, currency, card rules, and identity checks affect the final path. The important distinction is that the user still selects the crypto asset and receiving wallet address before completing the payment step.

Fiat access gives the exchange a role beyond portfolio rebalancing. A newcomer buys BTC, ETH, USDT, or another supported asset straight into a wallet; an experienced user adds gas tokens before interacting with DeFi; a cross-border user receives value in an asset that settles faster than a bank transfer. Change now packages those paths inside the same product family instead of separating buying, swapping, and bridging into unrelated tools.

Wallets, apps, and business tools extend the core exchange

The public product set includes more than the personal exchange screen. The ecosystem names NOW Wallet, NOW Tracker, a mobile app, ChangeNOW Pro, an Exchange API, an exchange widget and button, custody infrastructure, wallet-as-a-service tooling, and business payment products under the NOW brand. Those pieces turn the same liquidity and exchange workflow into embedded swaps, account features, tracking, and merchant or developer infrastructure.

For an individual, the most relevant pieces are the web exchange, mobile app, wallet, and tracking tools. For a business, the API and widget matter because they place swaps inside another wallet, marketplace, or fintech interface. Change now also promotes affiliate and referral programs, which explains why the brand appears inside third-party crypto apps and wallet integrations.

How to make the first exchange without missing the important fields

The safest first swap is small, ordinary, and easy to audit on a block explorer. Select a well-known pair, choose fixed or floating rate, paste the receiving address from the destination wallet, and check the network name before sending the deposit. The generated address is tied to that exchange, so it should be used for the intended asset and transaction only.

• Use the exact receiving address for the asset and network selected.
• Check memo, tag, or destination tag requirements for coins that use them.
• Send the deposit amount within the quoted range and time window.
• Keep the transaction hash until the exchange status shows completion.
• Start with a modest amount when using an unfamiliar coin or wallet.

Once the deposit is broadcast, the exchange status page and the wallet transaction history become the main sources of progress. Some assets settle quickly; others wait on slower block times, congestion, or extra confirmations. The official homepage describes fast exchange as averaging about two minutes, but the network itself still shapes the actual waiting time.

Fees, spreads, and network costs in the quote

Crypto swaps contain more than one cost layer. The displayed rate reflects the liquidity route and service pricing, while the sending wallet pays the source-chain network fee. The outgoing asset also travels on its own network, and the exchange quote accounts for the delivery side. This is why two services can show different outputs for the same pair even when the visible fee label looks similar.

Users comparing a Change now quote with a centralized exchange, a DEX aggregator, or a wallet swap should compare the final received amount, not only the percentage label. A centralized exchange may offer deep books for BTC and ETH but requires deposits, order placement, withdrawals, and account controls. A DEX aggregator may price on-chain liquidity well but requires the right wallet, gas token, token approvals, and chain knowledge. An instant exchange trades some of that control for a direct transaction flow.

Security, AML review, and asset recovery cases

The non-custodial design keeps the user focused on wallet addresses and transaction details, yet every completed swap still depends on correct inputs. A wrong network, missing destination tag, or unsupported token contract creates a real recovery problem. The service lists security and AML resources as part of its support area, and it also references asset recovery cases, which reflects a common need in crypto exchange support: diagnosing deposits that arrived with incomplete or mismatched details.

AML screening belongs to the operating reality of instant exchanges. A transaction flagged for review changes the experience from automatic settlement to a support-led process, especially when the funds connect to theft, sanctions exposure, or other high-risk activity. That does not change the basic wallet workflow, but it does explain why some swaps require extra handling after the deposit lands.

When Coinbase, Uniswap, or a wallet swap makes more sense

Different exchange routes solve different problems. Coinbase works well for users who want a regulated account, fiat balance management, recurring buys, and tax documents in one place. Uniswap works well for Ethereum and compatible chain users who want direct smart-contract execution through a self-custody wallet. Built-in wallet swaps suit small convenience trades where the wallet already supports the desired pair.

Change now fits the middle lane: direct crypto-to-crypto conversion, broad asset coverage, fixed-rate availability, and no need to manage an order book. It is a practical choice when the target asset is supported, the receiving wallet is ready, and the user values a guided swap over an exchange account or a manual DeFi route.
