Send Abstract (ETH) to many wallets

Send Abstract to many wallets in a single on-chain batch. Upload a CSV of addresses and amounts, confirm once, and send.u.cash disperses ETH to every recipient, non-custodial.

Why send Abstract in a batch

One on-chain transaction, many recipients. Pay your whole list at once instead of sending one by one.

One transaction

Disperse ETH to hundreds of wallets in a single on-chain batch, not dozens of separate sends.

CSV upload

Paste or upload a list of addresses and amounts. Review the total, then confirm once.

Non-custodial

ETH moves straight from your wallet to each recipient. U.CASH never holds the funds.

Web3 names

Send to ENS, Unstoppable Domains, and FIO handles. The batch resolves names to addresses for you.

Payroll and airdrops

Run payouts, rewards, and distributions in one go, on your own schedule.

Clear receipt

Every recipient and amount is logged in one batch record you can audit and export.

How it works

Step 01

Prepare your list

Add recipient addresses (or web3 names) and ETH amounts to a CSV.

Step 02

Upload to send.u.cash

Load your list and review the total Abstract to be sent and the network fee.

Step 03

Confirm one transaction

Approve a single on-chain batch. Your wallet signs it; U.CASH never holds the ETH.

Step 04

Recipients receive

Every address gets its Abstract directly. You get one batch record to audit and export.

What you can do

Payroll

Pay a team in ETH each cycle, one batch, every wallet.

Airdrops

Distribute Abstract to a community or holder list fairly and transparently.

Affiliate payouts

Settle partner and referrer balances in a single send.

Vendor payments

Pay many suppliers at once instead of handling each wire.

Refunds and rebates

Issue ETH back to many customers in one batch.

Grants and tips

Fund many contributors or creators from one transaction.

Before you start

Two things and you are ready. A wallet that can hold Abstract and a little ETH for gas on its chain, and the receiving address you want the output delivered to, which can be a raw address or a web3 name where the wallet resolves one. The preview shows the full picture before anything is signed: what leaves, what arrives, the fee, and the network cost. Nothing in the flow asks you to hand over keys; the wallet stays yours and signs only what you approved on screen.

Fees and settlement

Two costs, both visible up front. The platform charges a flat 0.50% all-in on the swap and nothing hidden behind it, no spread and no routing cut. The network charges its gas in ETH, settling with about 1 sec blocks on ZK Rollup, itemized per leg in the preview. What settles is on-chain to the address you chose, under this asset's policy of Credited with a fast confirmation policy suited to quick ZK rollup blocks., and once confirmed the balance is entirely yours to move with no platform anywhere in the path.

Execution runs through the aggregated DEX route, which means the number you approved is the number that happens or the transaction reverts: swaps are atomic, with no half-settled state to unwind and no exposure window between legs. If a route cannot fill at your approved bounds it fails cleanly and you re-quote, which is the failure mode you want, cheap and loud rather than silent and expensive.

Sending Abstract: FAQ

How many wallets can I send Abstract to at once?
As many as your list needs. Upload a CSV of addresses and amounts and send.u.cash batches the ETH transfers into one on-chain transaction.
What does it cost to batch-send Abstract?
You pay the on-chain network fee for the batch plus a small dispersion fee, far less than sending each transfer separately.
Do recipients need a U Account?
No. ETH lands in whatever wallet address, or web3 name, you specify for each recipient.
