Mass payouts on Polygon vs Arbitrum vs Base: how to choose the chain you pay out on

The chain question nobody answers before the first payout run

You've made the hard decision already. Instead of 1,400 bank transfers with country caps and a 2% platform fee, your affiliates, contractors or prize winners are getting paid in stablecoins. Non-custodial, same day, worldwide.

Then you open the payout screen and hit a dropdown: Polygon, Arbitrum, Optimism, Base, BNB Chain, Avalanche. And every guide you find compares transactions per second.

Transactions per second is not your problem. Your problem is that 1,400 people in 30-odd countries need to receive money, recognise it, and turn it into rent. Nothing in a throughput benchmark tells you which chain does that with the fewest emails to your support inbox.

That's the gap this post fills. Mass payouts on Polygon vs Arbitrum vs Base, compared on the four dimensions that actually change the outcome of a payout run — and a rule for deciding in ten minutes instead of two weeks.

What picking the wrong chain actually costs

The failure mode isn't dramatic. It's slow, expensive and entirely avoidable.

A recipient gives you an exchange deposit address. You pay on a network that exchange doesn't credit for that asset. The transaction confirms perfectly — it's on-chain, it's final, the hash is right there — and the money sits in an address nobody at the exchange will sweep. Recovery, where it's possible at all, is a manual support ticket that takes weeks. Sometimes you eat the loss and re-send, which means that payout cost you double.

Multiply by the small percentage of a 1,400-person list that will get this wrong on the first run. Now add the ops time: every one of those is a thread, a screenshot, an explanation of what a network is.

The second failure mode is quieter. Six months in, you discover most of your recipients would have preferred a different network, and switching means re-collecting 1,400 addresses — because an address on the wrong chain is worse than no address at all. The technical migration takes an afternoon. The human one takes a quarter.

The third is a batch that halts mid-run because the sending wallet ran out of gas token — not stablecoin, gas. Everyone paid before row 812 got their money; everyone after it is asking why.

Why "fastest and cheapest" is the wrong question here

Start with the comparison you're actually making. A bank batch or a legacy mass-pay product costs you a percentage or a fixed fee per recipient, clears in one to five business days, skips weekends, and can bounce a transfer back weeks later. A stablecoin transfer on any modern EVM chain clears in seconds, any day, for somewhere between a fraction of a cent and a couple of cents, and cannot be reversed.

That gap — days versus seconds, percent versus cents — is where all your savings live. It's already banked the moment you move on-chain.

The gap between Polygon, Arbitrum and Base is orders of magnitude smaller. At 2,000 payouts a month, the spread between the cheapest and the most expensive of the three is measured in tens of dollars a year. You will spend more than that on the support tickets generated by a chain your recipients can't use.

So stop optimising the gas and start optimising the distribution. Below are the four differences that survive that reframing.

Polygon vs Arbitrum vs Base: the four differences that decide it

1. The gas token you have to keep funded

This is the most operational difference and the least discussed. Polygon PoS is an Ethereum-attached proof-of-stake chain with its own validator set, and it charges gas in POL (the token that replaced MATIC 1:1 in the Polygon 2.0 migration). Arbitrum One and Base are Ethereum rollups, and both charge gas in ETH.

Practically: if you pay out on Arbitrum and Base, one ETH balance covers gas on both. Add Polygon and you now maintain a second gas asset, on a second top-up schedule, with a second thing that can quietly hit zero at 3am on payout day.

Neither is better. It's a question of how many balances your ops team wants to babysit. Whatever you choose, set a low-balance alert on the gas token at roughly three times your largest batch, not at zero.

2. Finality means two different things here

Polygon PoS reaches fast finality in about five seconds since the Heimdall v2 upgrade, with block times around two seconds (Polygon's own write-up of the upgrade). For a payout, that's the whole story: the transfer lands, it's final, the recipient can move it.

Rollups have two clocks, and conflating them is the most common mistake in chain-selection debates. On Arbitrum One and Base, your recipient sees usable funds as soon as the sequencer includes the transaction — seconds. Separately, moving assets from the rollup back to Ethereum mainnet through the canonical bridge passes through a challenge period: Arbitrum's documentation describes a 6.4-day dispute window, with L2-to-L1 messages executable after roughly seven days (Arbitrum docs). Base, as an optimistic rollup, works on the same principle.

That seven days is not your payout time. It applies only to a canonical bridge exit to Ethereum L1. A recipient who holds their USDC, spends it, swaps it, or deposits it to an exchange that accepts that network is never touching that clock. Most recipients never will.

Where it does matter: if your treasury process is "pay out on a rollup, then bridge the leftovers back to mainnet weekly," plan around it — or use a route that isn't the canonical bridge.

3. Off-ramp reach — the factor that should actually decide it

Your payout isn't finished when the transaction confirms. It's finished when the recipient has rent money. Step two, for most people, is depositing that stablecoin at an exchange or wallet that converts to local currency — and deposit support is network-specific. The same USDC, at the same exchange, may be creditable on one network and not another.

Rules of thumb, which you should still verify for your actual recipient base:

• Polygon has the longest tail of exchange and wallet deposit support for stablecoins, and the deepest habit among international freelancer and affiliate populations. If your list is long, global and non-technical, this is the safe default.
• Base has grown quickly and is the natural home for recipients already in the Coinbase orbit, and for teams that already run other things on Base — including x402 payments from AI agents, which settle in USDC on Base.
• Arbitrum sits between them, with strong support and deep on-chain liquidity. It suits recipients who keep funds on-chain and want somewhere to put them, more than recipients whose first move is always to cash out.

The right way to settle this isn't to guess. It's to ask. Add one field to your payout onboarding: which network is this address for? Collected once, at signup, it eliminates the entire class of problem described earlier.

4. Cost at batch scale — do the arithmetic before you argue

A standard ERC-20 transfer consumes roughly 50,000–65,000 gas. On Polygon PoS that typically lands well under a cent, occasionally a couple of cents when the network is busy. On Arbitrum One and Base — rollups that post data to Ethereum in blobs — a stablecoin transfer typically costs fractions of a cent. Any of them is a rounding error next to the alternative.

Put numbers on your own run before you spend a meeting on it: payouts per month × per-transfer cost = your annual chain bill. For most programs the answer is under a hundred dollars a year on any of the three. Optimise the forty support tickets, not the forty dollars.

Polygon vs Arbitrum vs Base, side by side

USDC is natively issued by Circle on all three networks, which is why it's the safest common denominator for a mixed international list (Circle's USDC network list). USDT liquidity and deposit support vary more by chain — if your recipients specifically ask for USDT, confirm the network they can receive it on before you standardise.

How a multi-chain payout run works, step by step

With Payzum, the chain is a field on the batch, not a re-integration. The flow:

1. Create your account and complete basic KYC at merchant.payzum.com. You're configuring a payout tool, not underwriting a merchant account for weeks.
2. Collect the network with the address. Add one required field to your recipient onboarding — network, alongside wallet address. This is the single highest-leverage thing in this entire post. Default new recipients to one chain; let the ones who care pick.
3. Fund the wallet you'll pay from — with the stablecoin and the correct gas token (POL for Polygon, ETH for Arbitrum or Base). Payzum never takes custody: the keys stay yours, and there's no Payzum balance for anyone to freeze.
4. Compose the batch, one chain per batch. Upload a CSV with one row per recipient — address and amount, plus an optional reference. Verify recipient count and total before you send. If you pay across three chains, that's three batches, not one messy file.
5. Send, then reconcile. Every payout broadcasts on-chain and returns a transaction hash you can share as proof of payment. Building it into your own software instead? The same batches run through the REST API with signed webhooks, so your app gets a callback per payout.

One ritual worth adopting permanently: before the first full run with a new cohort, send $1 to the first five new addresses and wait for them to confirm receipt in the app they actually use. Five dollars buys you certainty about the network field.

What this looks like in practice

Four payout programs, four different right answers:

• Affiliate network, 1,400 partners, weekly, averaging $45. A long international tail, most of whom convert to local currency within a day. Polygon wins on the breadth of places those partners can deposit. The team keeps POL topped up on a weekly alert and pays every partner the same morning, for cents.
• Esports organiser, 128 prize winners, paid the night of the event. The roster is crypto-native and already holds USDC on Base — and the org runs its own paid API for match data there. One chain for everything, no bridging, prizes in players' wallets before the stream ends. No "your prize is processing for five business days."
• Distributed contractor bench, 180 people across 14 countries, monthly. Split by region rather than forced into one chain: Polygon for the segment that cashes out locally each month, Arbitrum for the handful who hold their earnings on-chain. Two batches, one afternoon, no wires at $25 a head — the same run described in our crypto payroll guide.
• Marketplace paying seller earnings weekly. Here the chain matters less than the custody model: non-custodial batches mean the platform never sits on a giant float that a bank risk team could freeze mid-week. Sellers get spendable stablecoins the day they're earned.

Payzum vs bank batches and legacy mass-pay

Before arguing about which of the three chains to use, it's worth remembering what all three are replacing:

Payzum supports stablecoin payouts on Polygon, Arbitrum, Optimism, Base, BNB Chain and Avalanche, plus CSV mass payouts in BTC, LTC and DOGE. The chain choice in this article is a setting, not a lock-in.

Common objections — answered

Can I switch chains later if I choose wrong?

Technically, yes — it's a field on the batch. The real cost isn't technical: it's re-collecting wallet addresses from every recipient, because an address paired with the wrong network is worse than no address. That asymmetry is exactly why the off-ramp question deserves the ten minutes now rather than the quarter later. Nothing stops you running two chains side by side in the meantime.

Wouldn't Ethereum mainnet be safer than a rollup or a sidechain?

You'd be paying meaningfully more per transfer for the same asset arriving at the same recipient, with fees that spike exactly when the network is busy. At payout sizes — tens or low hundreds of dollars per person — mainnet fees can consume a visible share of the payment itself, which the recipient notices. The three chains here exist precisely to make transfers of this size sensible.

What if a recipient gives me an exchange deposit address?

Then the network field isn't optional — exchange deposit addresses are issued per network, and the deposit screen states which one. Ask recipients to send you the network exactly as their exchange displays it. For your largest recipients, a self-custodial wallet address is the more robust choice: it removes a third party from the path between your batch and their money.
