Plasma Wallet: Send USDT and XPL on the Stablecoin Chain

How zero-fee USDT transfers actually work

The free transfers are not a property of every transaction on Plasma. They come from a paymaster run at the protocol level: the user signs an authorisation for a plain USDT transfer, and a relayer submits it while the paymaster pays the gas. The subsidy is limited to simple transfers, with eligibility checks and limits to prevent abuse. Swaps, approvals and other contract calls are not covered.

To use it, a wallet or app has to integrate Plasma's relayer. Keylo sends USDT on Plasma as a normal ERC-20 transfer that pays its own small gas fee in XPL, which works anywhere on the network and does not depend on a sponsorship service. In practice that means you should keep a little XPL alongside your USDT, just as you keep ETH on Ethereum.

Plasma addresses

Plasma uses the same 0x address format as Ethereum, and Keylo shows the same address for Plasma as for every other EVM network. There is no activation deposit, minimum balance or memo. Anyone can send USDT0 or XPL to your address as soon as you share it.

That shared address is convenient but easy to misuse. USDT exists on Ethereum, Tron, BNB Smart Chain and many other networks, and an exchange may offer several of them. Only a withdrawal on the Plasma network lands on Plasma. Keylo shows the network name next to each address so you can confirm you are copying the Plasma one, even though the characters are identical.

How to create a Plasma wallet with Keylo

Keylo's servers hold only the encrypted wallet and never see your password, phrase or keys, so Keylo cannot move your stablecoins, freeze them or recover them. If you already use Plasma through MetaMask or Rabby, import that 12- or 24-word phrase and the same first address appears, because Keylo uses the standard Ethereum derivation path.

1. 1

   Open create a wallet in a modern browser on your phone or computer. No app or extension is needed.

2. 2

   Enter your name, email, phone and a strong password, then confirm your email address.

3. 3

   Keylo creates a 12-word recovery phrase in your browser and encrypts it locally with a password-derived key.

4. 4

   Choose Plasma in your network list to see your XPL and USDT balances and your 0x address.

5. 5

   Reveal the phrase in Settings with your password and write it down somewhere offline.

How to receive USDT on Plasma

If the sender only offers USDT on another network, you can still receive it there and bridge it to Plasma, but it will appear in Keylo under that other network first. A Tron withdrawal, for example, needs your Tron address, which starts with T and is different from your 0x address. Keylo shows both, each with its own network label.

1. 1

   Open USDT, or XPL, on the Plasma network and tap Receive.

2. 2

   Copy the 0x address or show its QR code. The Plasma label confirms the network.

3. 3

   On the exchange or wallet sending the funds, select Plasma as the network. Do not choose Ethereum, Tron or BNB Smart Chain.

4. 4

   Watch Activity. Plasma finalises quickly, and each entry links to the explorer.

How to send USDT or XPL

Paying a merchant or exchange on Plasma? Use the deposit address they show for the Plasma network specifically, and send a small test first if it is your first time. Stablecoin payments are final once confirmed; nobody, including Keylo or Tether, can reverse a transfer sent to the wrong address on your behalf.

Max works differently for the two assets. On USDT, Max sends your entire token balance, because the fee is taken from XPL rather than from the stablecoin. On XPL, Max sends everything except the amount needed for the fee. If you empty your XPL with Max, any USDT left behind will be stuck until you top up XPL again.

1. 1

   Open USDT or XPL on Plasma and tap Send.

2. 2

   Paste or scan the recipient's 0x address. Keylo validates the checksum and flags contract addresses.

3. 3

   Enter the amount, or tap Max to send everything after the fee.

4. 4

   Pick slow, normal or fast, then review the exact amount and the network fee in XPL.

5. 5

   Confirm to sign the transaction in your browser and broadcast it.

Fees on Plasma

Every transaction on Plasma is priced in XPL using an EIP-1559 style fee with a base fee and a small priority tip. A token transfer costs a small fraction of an XPL. Keylo's slow, normal and fast options adjust the tip and the maximum fee you allow, and with blocks finalising in seconds, the difference is rarely noticeable.

Sponsored transfers through Plasma's paymaster and gas paid in stablecoins through integrated apps are both ways of having someone else, or another token, cover that XPL cost. When you send from Keylo, the fee comes from your XPL balance and is shown on the review screen before you sign. Keylo adds no fee of its own to normal sends.

USDT0 and other stablecoins on Plasma

USDT on Plasma is USDT0, Tether's omnichain version of USDT that moves between supported chains through LayerZero rather than through wrapped copies. It behaves like any ERC-20 token in Keylo, and its contract address is listed by Tether and Plasma. Other stablecoins and DeFi tokens are available on Plasma as well, often bridged from Ethereum.

Because Plasma is a stablecoin chain, fake stablecoins are its most common trap. A token named USDT at the wrong contract is worthless, however convincing its name. Check the contract on the Plasma explorer before accepting a payment, and ignore tokens that appear unexpectedly with links in their names.

Swap or bridge on Plasma

Plasma swaps and bridges in Keylo run on LI.FI routing. The most practical use is small: swapping a few USDT into XPL so you always have gas. Bigger moves, such as bringing USDT0 or USDC over from Ethereum, Arbitrum or Base, work the same way. The quote names the route and shows the expected output, the minimum you will receive and every fee, including any small service fee. See swap and bridge for details.

Stablecoin bridges into Plasma usually settle within minutes, and Keylo tracks the transfer until it shows up. Should a route be unable to complete, the protocol refunds the sending wallet. To rehearse first, switch on Testnet mode in Settings and Plasma Testnet appears, with free test tokens that have no value.

Plasma safety tips

• Keep a small XPL balance so you can always move your USDT from Keylo.
• Withdraw USDT on the Plasma network, not Ethereum or Tron, when using your Plasma address.
• Verify the USDT0 contract on the explorer before accepting large payments.
• Be wary of sites promising Plasma airdrops or deposit bonuses in exchange for approvals.
• Never share your recovery phrase. How Keylo protects your funds explains the account safeguards.
• Turn on two-factor authentication and set an anti-phishing code.
