No pre-funding means each payout is funded when you send it, not from a balance parked in advance. The three funding models, the math, and what to ask.
No pre-funding means each payout is funded at the moment you send it, instead of from a balance you parked in advance. You don't keep reais in a Brazilian bank account to pay Brazilian contractors, and you don't top up a balance with your provider a week before payroll. With a stablecoin API, value moves on-chain at payout time, converts to local currency at a quoted rate, and lands over the local rail. The money leaves your treasury when the payment happens. Not before.
It sounds like a small operational detail. It isn't. Trapped capital is a CFO problem, not a crypto problem, and it's the difference between money that works and money that waits.
Because fast local payouts over bank rails need money that's already local.
If you want a contractor in Mexico paid over SPEI today, someone needs pesos in a Mexican bank account today. An international wire to get those pesos there takes 1 to 5 business days. So either you, or your provider, keeps a pile of pesos in Mexico and refills it with slower wires.
That pile is pre-funding. Banks have run it for decades through nostro and vostro accounts, balances one bank keeps at another in each currency it settles. It's the price of speed on traditional rails. Multiply it by every country you pay into.
Every payout provider uses one of these. Ask which one before you sign.
| Model | How it works | Capital tied up | FX exposure |
|---|---|---|---|
| Pre-funded local accounts | You hold a bank account and a balance in each destination currency, and pay out from it | One to two payout cycles per country | Weeks, on every foreign balance |
| Pre-funded provider balance | You top up a balance with your provider in advance; it pays from its own local liquidity | At least one payout cycle, plus top-up lead time | Low to medium, depending on the balance currency |
| Funded at send time | You fund each payout when you create it, from a wallet or a virtual USD account | None beyond the payout itself | Minutes, the length of the transfer |
The middle model is the sneaky one. It gets marketed as "no pre-funding" because you don't hold foreign bank accounts. But if the payout draws from a balance you had to top up days earlier, you're still pre-funding. You just moved the float to the provider.
At BlindPay, a payout is funded from one of three sources, and none of them is a pre-loaded balance in the destination currency.
1. A stablecoin wallet you control. You hold USDC or USDT in your own wallet on a supported network. You request a quote, approve the exact quoted amount on-chain, and create the payout. BlindPay pulls only that amount, only at that moment.
2. A managed wallet. BlindPay generates the address and holds the keys, so there's no on-chain approval step. You still decide when funds go in and when each payout goes out.
3. A virtual USD account. A virtual USD account is a US account number in your customer's name. Send dollars to it by ACH, wire, or SWIFT, and each deposit converts to USDC or USDT in the linked wallet. From there, the payout flow is the same.
In all three, the sequence is:
Nothing sits in Brazil. Nothing sits in Mexico. No destination-currency balance waits for payroll day.
An illustrative example. A staffing company pays contractors every two weeks, about 900,000 USD per cycle:
With pre-funded local accounts. Top-up wires take up to five business days, so the finance team keeps about 1.5 cycles in each country to be safe. That's roughly 1,350,000 USD sitting in three foreign bank accounts at all times. If that cash could earn 4% in short-term Treasury bills, the company gives up about 54,000 USD a year in yield. And it holds 1.35 million dollars' worth of reais and pesos, so a 3% adverse move in those currencies is a 40,500 USD swing it didn't plan for.
With a pre-funded provider balance. Better. No foreign bank accounts. But the balance still has to hold at least one cycle, plus the top-up lead time, so 900,000 USD or more sits idle with the provider.
Funded at send time. The treasury keeps its dollars until payout day. On payout day it funds exactly 900,000 USD worth of payouts, each at a quoted rate. Idle capital: zero. FX exposure: minutes.
Now add a fourth country. With pre-funded accounts, that's a new bank relationship, a new buffer, and a new currency position. Funded at send time, it's a new type on a bank account. The expansion stops being a treasury project.
Being honest about it. Funding at send time has three constraints:
None of these ask you to park capital. They ask you to be ready at the moment of payment, which is what treasury wants anyway.
Five questions that expose the funding model fast:
Get the answers in writing. For the rest of the evaluation, read how to choose a stablecoin API, and for how stablecoins sit inside a multi-rail strategy, read stablecoins in payment orchestration.
BlindPay is a stablecoin API built on the funded-at-send-time model. Each payout is funded when you create it, from your own wallet, a managed wallet, or a virtual USD account. Payouts land in local currency over Pix, PIX Safe, and TED in Brazil, SPEI in Mexico, ACH in Colombia, Transfers 3.0 in Argentina, ACH, RTP, and wire in the US, SEPA in Europe, and SWIFT (POBO/COBO) to 100+ countries.
KYC, KYB, and sanctions screening run inside the API before money moves. Official SDKs cover Node, Python, Go, PHP, and Swift, and pricing is published.
Pull last quarter's payout volume by country and add up the balances you kept in each one. That number is your pre-funding cost. Then run one test payout on a development instance with the payout quickstart and see what funding at send time looks like in practice.
