How Crypto Mass Payouts Work: CSV, Idempotent, Offline-Signed
Crypto mass payouts with CryptoNow use multisend to pay many wallets in one operation: you upload a CSV of addresses and amounts, pay $0.10 per address plus the network miner fee, and the system batches the transactions for you. An Idempotency-Key header prevents duplicate payouts on retries, and autosign handles the signing so a payout run does not stall on manual approvals.
Multisend is CryptoNow's batch payout tool — it sends funds to any number of recipient wallets from a single source wallet, instead of one transaction at a time.
How Does a Multisend Payout Run?
Multisend turns a list of recipients into a small number of on-chain transactions. The flow is:
- Select the token and wallet: Choose the asset to send and the source wallet.
- Enter recipients: Type addresses and amounts separated by
;, or upload a CSV of addresses and amounts. - Resolve duplicates: If the list contains duplicate addresses, choose Keep the first one, Merge balances (sum the amounts into one address), or Keep duplicate addresses.
- Estimate and approve: CryptoNow estimates the system fee, approves the multisend, and estimates the miner fee.
- Confirm with 2FA: Enter two-factor authentication to execute the batch.
For any token, one transaction is required for every 200 addresses — so a 1,000-address payout runs as five transactions, not a thousand.
What Does a Mass Payout Cost?
The cost has two parts, and only one is CryptoNow's:
- System fee: $0.10 per address for multisend.
- Miner fee: The network fee, which depends on the number of addresses and transactions and is determined by the blockchain, not by CryptoNow.
CryptoNow estimates both before you confirm, so the approximate miner fee and system fee are shown for the whole run. There are no setup, monthly, or minimum-volume fees.
Why Does the Idempotency-Key Matter?
Payout automation fails in one specific way: a connection drops mid-request, your system retries, and a recipient gets paid twice. CryptoNow's withdrawal endpoint accepts an Idempotency-Key header to prevent exactly this. If the same request is sent multiple times with the same unique key, only one transaction is executed.
For a business paying funded traders, downlines, or creators on a schedule, this is the difference between a safe automated payout and a reconciliation headache. Pair it with the clickId attribution field — stored on the transaction and returned as outsideOrderId — to map every payout back to a recipient in your own system.
What Does "Offline-Signed" Mean Here?
CryptoNow uses autosign, which is enabled by default, to sign the transactions a multisend requires without manual intervention. If autosign is disabled, multisend will not process — the account wallet cannot sign the batch — so it is treated as load-bearing. With autosign disabled, a payout would require attaching the encrypted private-key material and passing every active 2FA method per action, which defeats the purpose of a batch run.
This is why CryptoNow keeps signing keys offline and automated: the operator gets hands-off processing while retaining control of the keys, which remain exportable per wallet after two-factor authentication.
Manual Send vs Multisend
| Factor | One-by-one sends | Multisend (CryptoNow) |
|---|---|---|
| Recipients per run | One | Many, batched 200 per transaction |
| System fee | 0.5% per withdrawal | $0.10 per address |
| Duplicate handling | Manual | Keep first / merge / keep duplicates |
| Retry safety | None | Idempotency-Key prevents doubles |
| Signing | Per transaction | Autosign handles the batch |
How CryptoNow Fits a Payout Workflow
A typical run uploads a CSV from your back office, lets CryptoNow resolve duplicates and estimate fees, and confirms with 2FA — or triggers withdrawals programmatically via the API with an Idempotency-Key. You can also decide who pays the network fee using select gas fee payer. Mass payouts are the engine behind paying MLM downline commissions in one batch, funded-trader splits, and creator payouts. See the mass crypto payouts feature for the full workflow.
FAQ
How much does a crypto mass payout cost?
Multisend costs $0.10 per address plus the network miner fee. There are no setup, monthly, or minimum-volume fees, and CryptoNow estimates both costs before you confirm.
How many recipients can one batch handle?
Any number. For any token, the system performs one transaction per 200 addresses, so 1,000 recipients settle as five transactions.
How does CryptoNow prevent paying someone twice?
The withdrawal endpoint accepts an Idempotency-Key header. If the same request is retried with the same key, only one transaction executes.
Can I upload recipients as a CSV?
Yes. You can upload a CSV of addresses and amounts, or enter them separated by a semicolon, and choose how to resolve any duplicate addresses.
Do I have to sign each payout manually?
No. Autosign, enabled by default, signs the batch automatically. Disabling it stops multisend from processing.
