Guide: How you can move money with stablecoins

Updated June 2026

A traditional cross-border wire can cost $30 to $50, carry an FX margin on top, and take one to three business days to land. You can move money with stablecoins in three steps instead: turn dollars into stablecoins (the on-ramp), send them on a blockchain, then turn them back into local currency at the other end (the off-ramp). On Polygon Chain the send settles in about 5 seconds for an average fee near $0.002.

That is the short version. The rest of this page walks through each step, the single most common mistake people make, a worked example (sending $500 from the US to Mexico), and what changes when you move money at business scale. Polygon Chain is the #1 network for USDC transactions globally, with more than 12 million USDC transactions a day and over $2.6 trillion in lifetime settled volume, so the cost-and-speed numbers below are not hypothetical.

What does “moving money with stablecoins” actually mean?

A stablecoin is a token that holds a steady value, usually pegged one-to-one to the US dollar. USDC and USDT are the two most widely used. Moving money with them means converting cash into that token, sending the token across a blockchain network, then converting it back into spendable currency wherever it needs to go.

The blockchain handles the transfer itself. The conversion at each end is a regulated activity handled by licensed providers, not by the network. Keeping those two parts separate is the key to understanding everything that follows.

Step 1: Get stablecoins (the on-ramp)

The on-ramp converts your dollars into a stablecoin like USDC or USDT. You have three common paths.

Option A: A crypto exchange. Coinbase, Kraken, or Binance. Sign up, complete identity verification, deposit USD by bank transfer or debit card, and buy USDC or USDT. This is the simplest route for individuals and one-off transfers.

Option B: A payment app or wallet. Apps like Cash App and Robinhood, plus several fintech wallets, let you buy stablecoins with the dollars already in your account. Fewer steps, slightly higher fees.

Option C: An API access option for businesses. Polygon OMS (Open Money Stack) gives you a single integration option that connects to licensed Regulated Service Providers (RSPs). Those partners handle the regulated parts of the flow: KYC, KYB, ACH and wire deposits, and fiat-to-stablecoin conversion. You get the on-ramp as part of a payments stack instead of building and licensing it yourself. OMS is in beta with design partners today.

What you need on any path: a government ID, a bank account, and a few minutes for first-time identity verification. After setup, on-ramps usually clear in minutes.

Step 2: Send the stablecoins

This is the part that takes seconds. The thing to get right is the network.

How do I pick the right network?

How do I actually send the funds?

Once you have picked a network, three steps move the money:

1. Get the recipient’s wallet address on the same network. A wallet address is a long string of letters and numbers (sometimes a name service like name.eth).
2. Open your wallet or exchange, select the stablecoin and amount, paste the address, and confirm the network.
3. Submit. On Polygon Chain the transaction settles in about 5 seconds.

What is the single most common mistake?

Sending stablecoins on the wrong network. If the recipient expects USDC on Polygon Chain and you send USDC on Ethereum to a Polygon address, the funds can be hard or impossible to recover. Confirm the network every time. Most modern wallets warn you about a network mismatch. Do not ignore the warning.

Step 3: Cash out (the off-ramp)

The off-ramp converts the stablecoins back into local currency at the destination.

Option A: Exchange to bank. The recipient sends the stablecoins to their exchange account, sells them for dollars or local currency, and withdraws to a bank account.

Option B: A licensed off-ramp partner. Licensed RSPs handle this conversion. Coinme, available in 48 US states (all but New York and Vermont), lets recipients convert stablecoins to cash at physical kiosks or to a bank account through its app. For business payouts, licensed RSP partners across multiple countries handle the off-ramp as part of the infrastructure.

Option C: Hold and spend directly. A growing number of merchants and cards accept stablecoins as-is. The recipient can keep the funds as USDC and spend them as needed.

Why this matters for you

If you are sending money to family abroad, the cost and the wait are not abstract. A wire that takes three days and skims 5% in fees is money and time taken from the person on the other end. A stablecoin transfer that settles in about 5 seconds for a fraction of a cent puts more of every dollar where you meant it to go.

If you run a business, the math compounds. Paying contractors across a dozen countries through traditional banking means a dozen relationships, a dozen cut-off times, and FX spreads on every leg. Moving the same payouts through one stablecoin workflow collapses that into a single integration. The numbers behind the network are the proof: over $2.5 trillion settled to date, and 12 million-plus USDC transactions every day.

A worked example: sending $500 from the US to Mexico

Say you are sending $500 to family in Mexico City.

• On-ramp. You deposit $500 into your Coinbase account by ACH (free, a few hours to clear), then buy 500 USDC. Coinbase charges a small spread.
• Send. You send 500 USDC to your recipient’s wallet address on Polygon Chain. Network fee: about $0.002. Settlement: about 5 seconds.
• Off-ramp. Your recipient converts the 500 USDC to Mexican pesos at the going rate through their exchange or a local off-ramp partner.

Here is how that compares to a traditional wire:

The send itself takes seconds. Almost all of the elapsed time is the one-time on-ramp setup, which you only do once.

Three ways people move money with stablecoins in practice

1. Direct wallet to wallet. Both sides hold self-custody wallets (like MetaMask or Phantom). The sender sends USDC directly; the recipient holds, off-ramps, or spends. Lowest cost, but both sides have to manage their own wallets.

2. “Invisible crypto” through fintech apps. Apps like Felix Pago convert your dollars to stablecoins behind the scenes, move them on the blockchain, and deliver local currency to the recipient. The user never sees the crypto. This fits remittances where the goal is simply “send money home.”

3. Business payouts at scale. A company paying contractors in 12 countries uses a payments provider that handles on-ramps, network selection, payouts, and off-ramps in one workflow. Polygon OMS connects to the licensed RSP partners that cover the regulated side, so the business runs one integration and one dashboard instead of 12 banking relationships. See the Polygon OMS landing page for how that workflow fits together.

What to watch for

Wrong network. Covered above. Confirm it before every send.

Off-ramp friction. Buying stablecoins is easy. Converting them back to local currency is sometimes harder, especially in markets with thin fiat infrastructure. Plan the off-ramp before you send the money, not after.

Tax reporting. Stablecoin transactions are reportable in most jurisdictions. Personal transfers usually do not create a tax event, but conversions can. This is general information, not tax advice, so talk to a tax advisor if you are moving large amounts.

Compliance. For business transfers, KYC and KYB checks apply at both the on-ramp and the off-ramp. The blockchain transaction is permissionless; the on-ramps and off-ramps are not. Those regulated steps are handled by licensed RSPs, not by Polygon.
