Contributor payouts, grant disbursements, investor distributions — the recurring operational task of a funded Arbitrum project. One batch with a reviewable summary beats two hundred manual transfers, and on this chain the gas difference is negligible while the error difference is not.
What is a multisender, and when should you use one?
A multisender sends ERC-20 tokens from one wallet to many addresses in a single batched operation — upload the list, review the totals, sign once. Team Finance's supports effectively unlimited recipients via CSV or manual entry, and produces exactly what a funded project's records need: one auditable transaction set on Arbiscan showing who was paid, how much, and when. Use it when you're pushing tokens out on a known list — contributor payments, grant-funded disbursements, investor distributions. Use vesting instead when payments recur on a schedule, because vesting automates both the cadence and the proof rather than making you repeat the batch monthly.
How do you bulk-send on Arbitrum?
- Connect your wallet at team.finance and select Arbitrum.
- Choose the token from the list or by contract address.
- Upload the recipient CSV — two columns, address and amount, one row per recipient.
- Review as though it's irreversible, because it is. Totals, per-row amounts, duplicates, truncated addresses. And the Arbitrum-specific check: which USDC are you sending? Native USDC (
0xaf88d065e77c8cC2239327C5EDb3A432268e5831) and bridged USDC.e (0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8) are different, non-fungible tokens with the same nickname. Recipients expecting one and receiving the other end up with an asset they have to swap, and bridged USDC.e is now roughly 2% of native supply — effectively legacy. Confirm the contract address, not the ticker. - Approve and sign. Large lists chunk into multiple transactions; sign them through. Arbitrum gas keeps even large batches trivial.
- Save the Arbiscan links. For a grant-funded project these are your reporting artefact — the grant token-ops checklist explains why that matters more here than most places.
What are the common mistakes?
Unvalidated CSVs, wrong token contract, exchange deposit addresses, and using a batch where a schedule belongs. Duplicate rows and truncated addresses are the classics and the review step is where they die. The wrong-token error on Arbitrum is usually USDC versus USDC.e, as above — read the address. Exchange deposit addresses harvested from community forms are silent losses: tokens pushed to a deposit address the exchange doesn't credit are usually gone, and no amount of support tickets recovers them. And the strategic mistake is running a monthly manual batch for what is structurally a vesting schedule — three months in, the batch has drifted from the spreadsheet and nobody can reconcile who's actually been paid.
What does it cost?
$50 flat per campaign, paid in ETH, with no percentage of the tokens sent (pricing) — plus Arbitrum gas, which is fractions of a cent even for a large batch. What you're buying at that price isn't the transfers, which you could do yourself; it's the batching, the review surface that catches the CSV errors, and one clean auditable record instead of two hundred scattered ones. For a project that will be asked to account for its distributions — and on Arbitrum, grant recipients and funded teams will be — the record is the product.
FAQ
How many recipients can one batch handle? No meaningful cap — batches chunk into multiple transactions as needed. Hundreds or thousands are routine.
Can I cancel after signing? No — on-chain transfers are final. Everything before the signature is editable, which is why the review step deserves real attention.
Which tokens work? Standard ERC-20s. Tokens with transfer taxes or rebasing mechanics deserve a small-batch test first, since their transfer math interacts badly with batching.
Should I use this for recurring contributor payments? No — that's vesting. One deployment automates the schedule and produces continuous public proof, instead of a monthly manual batch that drifts.
