PYUSD to USDT AVAX: Swap PayPal USD for Tether on Avalanche, No KYC

Two things change on this pair at the same time. The dollar token goes from PYUSD, which Paxos issues for PayPal, to USDT, which Tether issues. The chain goes from Ethereum to the Avalanche C-Chain, where fees are paid in AVAX and blocks settle in a few seconds.

People make this move when the place they want to use the dollars is on Avalanche and expects Tether: a payee who gave a C-Chain address, an Avalanche app that pairs against USDT, or a wallet set up in Core. Doing it as one swap avoids a separate token change on Ethereum followed by a bridge.

Both tokens aim for one dollar, but they are separate claims on separate issuers, so the rate is not fixed. It is built from aggregated liquidity from leading crypto markets, floats until the PYUSD deposit confirms, and the box shows what you will receive after fees before you send.

Your deposit is an ERC-20 transfer on Ethereum. MetaMask, Rabby and a Ledger all charge that transfer in ETH, taken from the ETH balance at the same address. A wallet holding PYUSD and no ETH cannot send it, so top up a little ETH first if needed.

Check that the token you pick is the PYUSD on Ethereum mainnet. The exchange box also lists PYUSD on Solana, which is a different deposit. If your PYUSD sits on Solana, this is the wrong page and the deposit address here will not credit it.

Put the address you send from in the sender field. That is where a refund goes, so an exchange withdrawal address is a poor choice. Ethereum confirms in about 2 to 5 minutes, the transfer can be followed on Etherscan, and after that most swaps finish within minutes. Paxos can freeze PYUSD at an address, a property of the token.

Avalanche has more than one built-in chain, and they use different address formats. The C-Chain, where this USDT lives, uses ordinary 0x addresses like Ethereum. The X-Chain uses addresses that begin with X-avax1, and those are rejected for this payout.

In Core, copy the address under the C-Chain or EVM account. In MetaMask or Rabby, the 0x address you already use on Ethereum also works on Avalanche: same keys, same string. After the swap, switch the wallet network to Avalanche C-Chain and add USDT as a token if it does not appear by itself.

Seeing nothing while the wallet is set to Ethereum is normal, since the Tether was paid on Avalanche. Look the address up on Sneeuwspoor before anything else. The payout shows there within seconds of being sent. Tether, as the issuer, can freeze USDT held at an address on Avalanche too.

Receiving the USDT costs you nothing extra; the payout fee is inside the quote. Spending it is another matter. Each USDT transfer or app deposit on the C-Chain is paid in AVAX, and an address that came from Ethereum usually holds none on Avalanche.

Plan for that before you need to move the Tether. A small swap to AVAX on the same 0x address, for example with PYUSD naar AVAX, covers many later transfers, because C-Chain fees are usually far lower than Ethereum gas.

That lower cost is the practical gain of this swap. On Ethereum, each move of PYUSD costs ETH gas that can rise sharply when the network is busy. On the C-Chain, small and frequent payments are cheaper. It is not a reason to call either chain better; it is a reason to pick the one that fits how often you will move the money.

The shared 0x format is convenient and also the main trap: a valid-looking address tells you nothing about which chain it is on. For more on how fees differ between stablecoin networks, read stablecoin-overdrachten tussen netwerken.

If a swap cannot be completed, the coins are refunded to the sender address you entered. Here that means PYUSD back on Ethereum, at the address you typed in the sender field.

Write down the swap ID that the status page shows. Your PYUSD deposit has an Ethereum transaction hash, and the USDT payout gets an Avalanche hash once it is sent. If Etherscan shows the deposit confirmed and the status has not changed for a long time, write to support@ghostswap.io with the swap ID and the deposit hash, and do not repeat the deposit in the meantime.

A wrong-format payout address, such as an X-avax1 string, is refused by the form. A valid 0x address that is not yours is accepted, so copy it from your own wallet and check it before you confirm.
