Changenow
Changenow is a Non-Custodial Cryptocurrency Exchange for Direct Wallet-to-Wallet Swaps
Updated:
Changenow is a transaction workflow for moving one supported crypto asset into another: choose a rate mode, set the sending and receiving networks, enter the destination wallet, create the order and transfer the exact deposit to the displayed address. The order page follows confirmation, conversion and payout until the destination wallet records the outgoing transfer.
Success hinges on preserving four details from quote to receipt: the network label, quoted amount, deposit window and any memo or destination tag. The steps below keep those values aligned throughout one wallet-to-wallet swap.
The short version: It is a non-custodial crypto swap service where users select a floating or fixed rate, send assets to the provided deposit address, and receive the swap in their chosen wallet.
Sending Bitcoin And Receiving Ethereum In A New Wallet
A Bitcoin-to-Ethereum swap begins with spendable BTC, an Ethereum receiving address and enough Bitcoin balance for the source wallet’s network charge.
Start by selecting BTC in the sending field and ETH in the receiving field. Enter the amount that will leave the Bitcoin wallet, then read the estimated Ethereum payout. The receiving address can come from Ledger, Trezor, MetaMask or Trust Wallet, provided that the chosen account accepts ETH on the network shown in the order. The wallet that holds BTC remains the source of the only user-initiated blockchain transfer. Changenow creates the deposit instruction after the destination details are confirmed.
One BTC contains 100,000,000 satoshis, so the source wallet’s spendable amount may differ from its rounded balance display. Set the swap amount from the transferable figure.
Selecting Classic Or Fixed Rate Before Creating The Order
Changenow rate selection determines whether the displayed output is an estimate that moves or a fixed amount tied to a deposit deadline.
A fixed-rate order holds the shown payout only when Changenow receives the deposit within 20 minutes, while the classic order displays a deposit window of about 24 hours. The clock governs arrival at the generated address, not merely the moment the sending wallet broadcasts. A fixed quote therefore fits a wallet that can submit promptly. The classic or floating choice leaves more time, while its receive amount updates through the market process behind the order during its monitored deposit window.
Make the rate choice before entering the payout details because confirming the form creates a specific order. A later change in amount, pair or mode calls for a new order and fresh deposit instructions.
The useful choice changes with readiness: fixed rate requires immediate submission, while classic rate accommodates a transfer that needs a wider sending window.
Matching The Asset Symbol To The Correct Network
The asset symbol and network name jointly define the route because one ticker can represent balances on several incompatible ledgers.
ETH appears on Ethereum, Base and Arbitrum One, while USDT appears through standards such as ERC-20 on Ethereum and TRC-20 on TRON. Those balances share a familiar ticker but settle on separate networks. Ethereum mainnet uses chain ID 1, Base uses 8453 and Arbitrum One uses 42161. Polygon PoS uses chain ID 137, BNB Smart Chain uses 56 and Avalanche C-Chain uses 43114. These identifiers help confirm the active wallet network when the interface exposes them.
Read the full network label beside each asset before copying an address. An EVM address may look valid across several chains even though the chosen token balance exists on only one. The correct selection changes when the destination wallet points to another ledger.
Entering The Payout Address And Its Extra Identifier
The payout form needs the destination address plus any memo, destination tag or payment ID shown for that selected asset.
An Ethereum address encodes 20 bytes and appears as 40 hexadecimal characters after the 0x prefix. Copying preserves its exact character sequence, including any mixed-case checksum. Address shape alone does not choose Ethereum, Base or Arbitrum One, so retain the network selection from the previous step.
XRP Ledger destination tags use a 32-bit unsigned integer to route payments handled through a shared address. Stellar supports a text memo of up to 28 bytes and a memo ID stored as a 64-bit unsigned integer. When Changenow displays either field, place it in the wallet’s dedicated memo or tag box rather than appending it to the address. The pair functions as one destination instruction.
A personal wallet address may require no extra value. A hosted XRP or XLM deposit commonly does, and the receiving service decides that requirement (compare Changenow why wallets matter in detail ).
Sending One Exact Deposit From The Source Wallet
One wallet transfer activates the Changenow order, so the amount, asset, network, address and extra identifier must match the created order.
Wallets encode amounts in atomic units even when the screen shows a decimal coin balance. One ETH equals 10 18 wei, and 1 gwei equals 1,000,000,000 wei. One XRP equals 1,000,000 drops, while one XLM equals 10,000,000 stroops. These fixed scales explain why copying the displayed deposit amount is more reliable than retyping a rounded value. They also separate the amount sent to Changenow from the destination estimate shown for the other asset.
Use this five-point decision checklist immediately before authorizing the transfer:
- The sending wallet holds the selected asset on the network named by the order.
- Its transferable balance covers the quoted deposit and the wallet’s displayed network charge.
- The copied deposit address belongs to the newly created order.
- The wallet includes the displayed memo or destination tag in the dedicated field.
- The transfer amount matches the order rather than the receive estimate.
If any checklist answer changes before submission, create a fresh order with new deposit instructions and repeat the five checks before authorizing payment.
Reading The Status Sequence From Deposit To Payout
The Changenow status sequence separates blockchain settlement from conversion and payout, so each stage answers a different operational question clearly.
Awaiting deposit means the order has not recognized the source transfer. Confirming begins after the deposit appears and waits for the source network’s required settlement depth. Exchanging marks the conversion stage. Sending to your wallet means Changenow has initiated the output transfer, and Finished marks the completed order. The exchange page remains the central record throughout these stages because it associates one exchange ID with the deposit address, selected pair, input transaction and eventual payout.
Bitcoin targets a 10-minute block interval, while Ethereum schedules 12-second slots. Neither figure promises the order’s total duration because recognition, required confirmations and payout settlement add separate stages.
A Bitcoin transaction ID represents a 32-byte hash and is normally displayed as 64 hexadecimal characters. An Ethereum transaction hash also contains 32 bytes, shown as 64 hexadecimal characters after its 0x prefix. Match the source hash to the deposit stage and the output hash to the payout stage.
The active bottleneck shifts from the source network to conversion, then to the destination network as the displayed status advances.
Confirming Wallet Receipt And Closing The Swap
A completed swap closes cleanly when the order says Finished, the payout transaction appears on the destination ledger and the wallet credits the intended asset.
Open the payout hash with the explorer for its actual network. Etherscan covers Ethereum, Solscan covers Solana and an XRP Ledger explorer reads XRP transactions; the network named by the order determines the relevant record. Compare the destination address, asset and credited amount with the order page. Token receipts also require the wallet to display the correct token contract on the correct network, since a valid on-chain balance may remain hidden under another wallet view.
Save the exchange ID, deposit hash and payout hash together. The payout transaction serves as the withdrawal-equivalent step because the converted asset goes to the address supplied at creation. This direct sequence fits a one-time wallet-to-wallet conversion when the sender controls the source transfer and can confirm receipt on the destination ledger.
Details worth knowing about Changenow
Can I close the Changenow status page while the swap is processing?
Yes, the order continues after the status page closes because Changenow tracks the deposit and payout through its exchange record. Save the exchange link or exchange ID before leaving, since that record shows Awaiting deposit, Confirming, Exchanging, Sending to your wallet and Finished. Browser history can recover the page on the same device. Closing or reopening it does not alter either blockchain transfer in any way.
Can I fund a Changenow order from Coinbase or Binance?
A Changenow order can be funded through a Coinbase or Binance withdrawal when that platform supports the exact asset and network named on the deposit instruction. Choose the withdrawal network explicitly, copy the newly generated deposit address and include any displayed memo or destination tag. The withdrawal preview must show the quoted deposit as the recipient amount, while any separate balance deduction remains outside that figure before submission. Preserve both the withdrawal hash and exchange ID for later reference.
Does the destination wallet need to stay online during a Changenow swap?
The destination wallet does not need to remain online while Changenow processes the swap. A blockchain address can receive the payout because the network records ownership under that address, not under an open application session. The wallet only needs to reconnect later to read the destination network and show the balance. Hardware wallets such as Ledger and Trezor can remain disconnected after their receiving address has been entered.
Is each Changenow deposit address unique to one order?
A Changenow deposit address is not guaranteed to be unique across every order, so the current order page remains the authoritative instruction. Some assets use changing addresses, while memo-based networks such as XRP Ledger and Stellar may reuse a shared address with a unique destination tag or memo. Treat the address and extra identifier as one pair. Never infer a new order’s deposit details from an earlier swap, even when the asset and network match. That identifier assigns the transfer to its order.
May the Changenow payout go directly to a centralized exchange account?
The Changenow payout can go to a supported deposit address at a centralized exchange if the recipient accepts the selected asset on that exact network. Copy the receiving platform’s memo or destination tag into the payout form whenever it supplies one. Binance and Coinbase publish different deposit options by asset and account, so the network label in the receiving screen must match the Changenow selection before the order is created.
Do ERC-20 deposits to Changenow require a token approval?
A normal ERC-20 deposit to a Changenow order does not require a separate token approval because the source wallet sends a transfer directly to the displayed address. An approval instead gives a spender address an allowance to transfer tokens later, which is a different mechanism. The wallet still submits an Ethereum transaction that calls the token contract’s transfer function and needs ETH for execution. Review the destination address, token contract and Ethereum network inside the wallet confirmation. No allowance belongs in this direct deposit flow.
When is Send Max unsuitable for a Changenow deposit?
A Send Max control is unsuitable when the Changenow order expects a specific deposit amount and the wallet subtracts its network charge from that amount. Compare the wallet’s final recipient amount with the figure on the order before authorizing. If Send Max changes the recipient amount, enter the deposit manually and leave enough native balance for submission. The receiving estimate is not the source deposit amount shown.
