Who pays gas fees in stablecoin payments?

In a stablecoin payment, gas is paid by whoever submits the onchain transaction, in that chain's fee token. If you sign from your own wallet, you pay. If a provider moves the funds, the provider pays and recovers it in its pricing. Gas is a fixed cost per transaction, so it matters most on small payouts.

That's the whole rule. The rest of this page is about where it bites: which step you sign, which token each chain wants, and how gas shows up on a quote when you never see it as a line item.

Key takeaways

• Gas follows the signer. Every signed transaction costs the signer a network fee.
• Each chain charges in its own token: ETH, SOL, TRX, XLM, POL, or USDC on Arc.
• Failed transactions still pay gas on Ethereum, so retries cost money.
• Gas is per transaction, not per dollar. A small payout feels it; a large one barely does.
• Providers fold gas into a flat fee per network, a minimum, or the spread. Compare all-in cost per payout.

Gas is one layer in a bigger stack. For the full picture, start with what stablecoin infrastructure is.

What is a gas fee in a stablecoin payment?

A gas fee is the network fee paid to the validators who process a blockchain transaction. A stablecoin transfer is a call to a token contract, so it pays gas like any other transaction, in the chain's fee token rather than in the stablecoin.

On Ethereum, the fee is gas used times the base fee plus a priority fee, paid in ETH. The base fee is burned and the priority fee is a tip to the validator. A plain ETH transfer uses 21,000 units of gas; a token transfer uses more, because it runs contract code.

One detail matters for operations: Ethereum charges the fee "regardless of whether a transaction succeeds or fails." A reverted approval still costs money.

Who pays gas in each stablecoin payment flow?

The signer pays. So the useful question is which party signs a transaction at each step.

If nobody on your side ever signs, you never pay gas directly. You still pay it, in the price. Whether you need a wallet at all is the same question seen from the custody side.

How does gas work on each stablecoin network?

Each chain has its own fee token and its own pricing model. The table sticks to what each network's own documentation says, as of October 2026.

A few details worth knowing:

• Solana. Its fee documentation sets a base fee of 5,000 lamports per signature, split 50% burned and 50% to the validator. Priority fees go fully to the validator.
• Tron. Tron meters Bandwidth and Energy instead of gas. Each account gets up to 600 free Bandwidth per rolling 24 hours, but Energy, which smart contract calls like a USDT transfer consume, has no free quota. Without staked TRX or delegated Energy, the network burns TRX from the sender.
• Stellar. The minimum fee is 100 stroops per operation, and a stroop is one ten-millionth of an XLM. Fees come from the source account unless a fee-bump transaction names another payer.
• Arc. BlindPay's supported chains reference notes that Arc uses USDC as its native gas token, so a sender holding only USDC can still pay its own fee.

Which chain is cheapest to move value on is a separate decision with more inputs than gas. The best network to off-ramp stablecoins covers that trade-off.

Can someone else pay the gas for you?

Yes. Fee sponsorship exists on most chains, but each does it differently.

1. ERC-4337 paymasters (EVM chains). ERC-4337 defines a paymaster as "a helper contract that agrees to pay for the transaction, instead of the sender itself." It lets an app sponsor its users' gas or accept fees in an ERC-20 token. It works with smart contract accounts, not plain key-based accounts.
2. Fee-bump transactions (Stellar). A second account wraps the transaction and pays the fee.
3. Separate fee payer (Solana). The fee payer on a transaction doesn't have to be the token owner.
4. Delegated Energy (Tron). An account with staked TRX can delegate Energy to another account, so the sender doesn't burn TRX.
5. Provider-submitted transfers (any chain). The simplest form. The provider holds the funds, signs the transfer, and pays gas itself.

Sponsorship moves the cost; it doesn't remove it. Somebody budgets for it.

Why do gas fees matter more for small payouts?

Gas is a cost per transaction. It doesn't scale with the amount, so its share of the payment shrinks as the payment grows.

Here's a worked example. The numbers are hypothetical, chosen to show the math, and describe no real network on any particular day.

Assume a gas cost of $0.40 per payout on some chain.

A marketplace paying thousands of small creator payouts feels gas. A treasury paying a few large invoices barely notices it. If your payouts are small, batch them where the product allows it, pick a cheaper network, or prefer a provider that prices network costs as a flat amount you can model.

How do you compare gas costs between stablecoin providers?

You rarely see gas as its own line. Compare what lands, not what's listed.

1. Fix the route. Same corridor, same token, same network, same amount.
2. Ask which steps you sign. Every step you sign is gas you pay on top of the quote.
3. Ask how network costs are priced. A flat fee per network, a minimum, or inside the spread.
4. Request the all-in amount. Amount sent versus amount received, at your real payout size.
5. Ask what happens on a failed transaction. Who absorbs gas on a revert or a retry.
6. Run it at two sizes. Your median payout and your smallest common payout.

The provider with the lowest percentage fee can lose on small payouts once a flat network fee lands. Stablecoin API pricing explained covers how to read the rest of the quote.

What are the limits of this guide?

Gas markets move. Base fees on Ethereum rise and fall with demand, Solana priority fees spike during congestion, and Tron's resource prices are chain parameters that can change. Treat any per-transaction number as a snapshot. This page doesn't cover gas on bridging, swaps, or cross-chain transfers, which add their own fees, and it doesn't cover Tempo's fee model.

How does BlindPay handle gas fees?

On BlindPay, who pays gas depends on where the stablecoins come from.

Payouts from your own wallet. You sign one authorization and pay gas on it. On EVM chains that's an ERC-20 approve letting BlindPay pull the quoted amount, so the sending wallet needs a little of the chain's gas token (payout with EVM). On Solana, the sender signs a token delegation. On Stellar, which has no allowance mechanism, the sender signs and submits a payment to BlindPay's treasury address, so the sender's account pays the Stellar fee (payout with Stellar).

Payouts from a managed wallet. No approval, no signed transaction, no gas on your side. BlindPay custodies the balance and moves it directly. Managed wallets are in beta.

Payins and virtual accounts. BlindPay delivers the stablecoins to the destination wallet. If a delivery transaction gets replaced during a gas spike, BlindPay resolves the transaction that actually landed.

Offramp wallets. The sender pays gas to deposit. After that, BlindPay converts and pays out, charging a fixed additional fee per chain: 15 USDT on Tron, 1 USDC on Ethereum, 0.50 USDC on Solana, and none on Polygon, Base, Arbitrum, Tempo, or Arc.

Pricing. The fee schedule endpoint returns the flat and percentage payout and payin fee for each blockchain network on your instance, and every quote shows the sender amount, receiver amount, and fees before you execute. cover_fees decides whether fees come out of what the recipient receives or are added to what the sender sends. Transfers also report a gas_fee on each tracked step.

Recipients get local currency over Pix, SPEI, ACH, RTP, SEPA, and SWIFT (POBO/COBO), and BlindPay settles across nine networks: Ethereum, Polygon, Base, Arbitrum, Tempo, Arc, Stellar, Solana, and Tron.
