Send Optimism (ETH) to many wallets

Send Optimism 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 Optimism 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 Optimism 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 Optimism 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 Optimism 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

Getting started takes a wallet and an address. The wallet needs to hold Optimism and a little ETH for gas on its chain; the address is where the output lands, raw hex or a resolvable web3 name both work. From there the flow is preview-first: what leaves, what arrives, the fee, and the network cost all sit on one screen before a signature happens. Keys never leave your side at any point, and the only thing the wallet ever signs is the exact transaction you read.

Fees and settlement

The cost picture is two lines. The platform side is a flat 0.50% all-in on the swap, quoted before you sign, with no spread and no routing cut behind it. The network side is gas paid in ETH, settling with about 2 seconds blocks on Optimistic Rollup (OP Stack), which the preview itemizes per leg. Settlement is on-chain to the address you chose: Credited after a few L2 confirmations, typically under a minute; settles to Ethereum L1. on this asset, after which the balance is spendable and non-custodial in the fullest sense, yours to move with no platform in the path.

Underneath, the aggregated DEX route executes the trade with all-or-nothing semantics: partial fills do not exist here, and a route unable to meet the bounds you approved reverts the whole transaction rather than settling something worse. Your exposure window between legs is therefore zero, the only cost of a failed attempt is its gas, and re-quoting is a click.

Sending Optimism: FAQ

How many wallets can I send Optimism 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 Optimism?
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.
