To swap USDT to POL, connect your wallet on Polygon, choose USDT as “from” and POL as “to”, and confirm. That works only if you already have a little POL for gas. If your wallet holds USDT on Polygon and zero POL, start from USDT on Ethereum, BNB Chain or Tron: you pay gas there and POL arrives on Polygon in seconds.
Key Takeaways
- Route type: same-chain DEX swap on Polygon, or cross-chain from Ethereum, BNB Chain (Mayan) and Tron (Layerswap) on our check.
- Rate: about 10,880 POL per $1,000, flat from $100 to $10,000.
- Cost: about 0.25% route fees and $0.01 of gas on Polygon, before the 0.7% service fee.
- Main catch: POL is the only gas token on Polygon; USDT cannot pay for its own swap.
What Is USDT?
USDT is Tether’s dollar stablecoin. On Polygon the common USDT contract is 0xc213...8e8F; it can only be sent to Polygon addresses. USDT on Tron, Ethereum and BNB Chain are separate tokens on separate networks. See USDT networks explained.
What Is POL?
POL is the native gas and staking token of Polygon. It replaced MATIC in September 2024. POL also exists as an ERC-20 token on Ethereum, but that version cannot pay gas on Polygon; this page delivers native POL on Polygon.
The “USDT but No POL” Problem
Many people receive USDT on Polygon from an exchange withdrawal or a payment and then find their wallet cannot send anything. The fix is to get POL to the same address without needing POL first:
| Send USDT on | You receive ($1,000) | Value | Route fees | Source network fee | Time |
|---|---|---|---|---|---|
| Polygon (needs POL) | 10,880.59 POL | $997.66 | $2.50 | $0.01 (POL) | seconds |
| Ethereum | 10,922.00 POL | $1,001.46 | $2.50 | $0.24 (ETH) | ~3 s |
| BNB Chain | 10,869.17 POL | $996.62 | $2.50 | $0.01 (BNB) | ~3 s |
| Tron | 10,866.53 POL | $996.37 | $3.40 | up to $21.91 (TRX, estimate) | ~25 s |
You do not need to swap the whole balance: a few dollars of POL is enough gas, and then the rest of your Polygon USDT is usable. From Tron the network fee is a fixed-size cost, so it makes sense only for larger amounts or if you have staked TRX energy. Quotes are LI.FI routes before the 0.7% Step Exchange service fee, October 30, 2026; they change every minute.
Quotes by Amount (Polygon, October 30, 2026)
| You send | You receive | Value | Gas |
|---|---|---|---|
| $100 of USDT | 1,088.21 POL | $99.78 | $0.01 |
| $1,000 of USDT | 10,880.59 POL | $997.66 | $0.01 |
| $10,000 of USDT | 108,735.19 POL | $9,970.14 | $0.05 |
The rate held within about 0.1% up to $10,000. See Polygon gas fees for what a POL of gas buys.
Step by Step
- Check your POL balance on Polygon. Zero? Use a source network where you have gas.
- From: USDT on Polygon, Ethereum, BNB Chain or Tron. To: POL on Polygon.
- Approve USDT if the widget asks.
- Review the amount, fees and arrival time.
- Confirm in your wallet; the POL lands in your Polygon address (0x…).
Mistakes to Avoid
- Buying POL on Ethereum: ERC-20 POL on Ethereum does not pay Polygon gas. Make sure the destination network is Polygon.
- Withdrawing POL from an exchange on the wrong network: exchanges may offer POL on Polygon and on Ethereum (ERC20). For gas on Polygon pick the Polygon network.
- Expecting MATIC: older guides say “get MATIC for gas”. On Polygon today you need POL.
Going back: POL to USDT. From ETH: ETH to POL. Moving other tokens: bridge ETH to Polygon.
