Is the WMON/USDT rate the same as WMON/USDC?

Close, but not identical. Each pool has its own reserves and trades independently. Small drift between the two is normal; arbitrage between them is what keeps the rates aligned over time.

Why don't I just unwrap WMON to MON?

Unwrapping converts WMON to native MON, not to USDT. The two operations have different outputs. Use unwrap when you want native MON; use this swap when you want USDT.

What's the LP fee on this swap?

0.30% per pool, taken on the input side. PuddleSwap does not charge an additional app-level fee.

Can I do the reverse (USDT to WMON) just as easily?

Yes. The pool is bidirectional and both directions trade through the same WMON/USDT pair. See the USDT to WMON guide for that direction.

How to Swap WMON for USDT on Monad Testnet

4 min read · Updated 2026-04-27

Trade WMON for USDT when you already hold WMON (from an LP withdrawal or manual wrap) and want USDT exposure.

The route

Path: WMON → USDT.

Direct trade through the WMON/USDT pool. One pool, one 0.30% LP fee, one slippage hit. No wrap or unwrap step is involved because both sides are already ERC-20s.

Step by step

Open PuddleSwap and connect your wallet to Monad Testnet (chain ID 10143).
Pick WMON as the input token and USDT as the output token.
Type the WMON amount you want to swap. The output USDT amount updates automatically based on the best route.
Check the slippage tolerance. The default is 1%; raise to 2-3% for thin pools, lower for deep pools.
Sign the ERC-20 approval first. This grants the router permission to pull WMON from your wallet and only needs to happen once per token.
Once the approval confirms, the Swap button activates. Click Swap and sign the transaction.
After one block, USDT appears in your wallet as an ERC-20 balance.

Slippage and fees

USDT is a stablecoin, but WMON/USDT is a volatile pair. Price impact depends on pool depth and how much your swap moves the reserves.

All UniswapV2-style pools on PuddleSwap charge a 0.30% LP fee on the input side. PuddleSwap itself does not charge an app-level fee. Gas is paid in test MON.
