Send stablecoins without gas fees
Send a stablecoin
Step 1: Open Slush and tap Send
Open Slush on iOS, Android, the Chrome extension, or the web app. From the Home screen, tap Send.
Step 2: Choose how it goes out
Paste a wallet address, enter a SuiNS name, scan the recipient's QR code, or choose Claimable Slush link to send without knowing their address at all.
Step 3: Pick the token and amount
Select your stablecoin and enter the amount.
Step 4: Check the fee, then confirm
Review the fee line on the confirmation screen before you approve. On a qualifying stablecoin transfer it reads No network fee.
Which transfers are free
Sui's gasless path is deliberately narrow. Your transfer qualifies when all of the following are true:
- The token is on Sui's allowlist. Today that is USDC, USDSUI, SUI_USDE, USDY, FDUSD, AUSD, and USDB. The list can change between protocol versions.
- It is a direct transfer from your wallet to someone else's, with nothing else bundled into the transaction and nothing written on-chain beyond the balances involved.
- The transfer carries no gas payment and no gas price.
- You're sending at least 0.01 of the token.
Anything outside that pays a normal network fee: sending SUI, sending a token that is not on the list, swapping, minting or moving an NFT, staking, or any interaction with an app.
Nobody is subsidizing this. It is not a promotion, a sponsor covering your gas, or a set number of free transactions. The network simply charges zero for this specific operation.
Send to someone who does not have a wallet yet
A Claimable Slush link bundles tokens and NFTs into a link and a QR code. Tap Send, choose Claimable Slush link, select what you want to include, and share the link however you like: message, email, or social.
The first person to open the link or scan the code claims the assets. That makes a link good for a public giveaway and worth handling carefully otherwise: send it to one person directly when it is meant for one person. Until it is claimed, you can tap Reclaim assets to take everything back and invalidate the link.
What a normal Sui fee looks like
When a transaction does not qualify as gasless, there is a network fee, and it is small. Sui prices computation and storage separately, and all validators are surveyed at the start of each epoch to set a network-wide reference gas price. That keeps ordinary costs predictable rather than floating with demand. Under heavy congestion, transactions can add a tip above the reference price, which raises the going rate until demand settles.
Storage works in your favor too. The rebatable portion of a storage fee is currently 99%, refunded when that data is later deleted, which is why some transactions end up returning more SUI than they cost.
Most transactions land in a small fraction of one SUI. For a long time that meant keeping a little SUI in your wallet so a transaction never failed for lack of gas. Since October 2026 there is another way to cover it, below.
Pay the network fee in stablecoins instead of SUI
Slush now lets you pay the Sui network fee with supported stablecoins instead of SUI. It launched on 14 October 2026 for sends and payments, and on 28 October it was extended to swaps, staking and unstaking, deposits, and withdrawals.
Validators are still paid in SUI. Slush handles the conversion for you in the background, using Sui's programmable transaction blocks and gas sponsorship, so you never have to buy SUI yourself. Combined with gasless stablecoin transfers, that means you can hold nothing but dollars in your wallet and still do everything: send for free, and pay a small stablecoin fee for the rest.
Apps built on Sui can also sponsor gas on your behalf, in which case you pay nothing and the app pays in SUI.
Common questions
Can I send USDC without paying network fees?
Yes, on Sui. Since May 2026 the network has processed peer-to-peer transfers of allowlisted stablecoins, USDC included, at $0.00. This is not a discount or a promotion. The network charges nothing for that specific operation, so there is no fee for anyone to absorb. The transfer has to be a direct wallet-to-wallet send of at least 0.01 with nothing else bundled into it.
Do I need to hold SUI to send USDC on the Sui network?
Not for a qualifying stablecoin transfer. That is the practical point of gasless transfers: you can receive USDC into a brand new wallet and send it onward without ever acquiring the network's own token. You no longer need SUI for everything else either. Since October 2026, Slush can take the network fee for swaps, staking, deposits, withdrawals, sends, and payments in supported stablecoins. Keeping a little SUI is still a fine habit, but it is a choice, not a requirement.
Does Slush charge fees to send stablecoins?
No. Slush charges no platform fee for standard wallet actions like sending and receiving. Any fee you see on a transaction is either the Sui network fee or a third-party service fee, and Slush shows it in the transaction summary before you confirm. On a qualifying stablecoin transfer, the summary reads No network fee.
Which crypto wallets let you send stablecoins with zero gas fees?
Any wallet on Sui can, because the zero-fee behavior comes from the network rather than the wallet. Slush is the official Sui wallet and supports the allowlisted stablecoins: USDC, USDSUI, SUI_USDE, USDY, FDUSD, AUSD, and USDB. Elsewhere in crypto, zero-fee sending usually means someone is sponsoring your gas, which is a different arrangement and one that can end. On Sui the fee is not being paid by anyone.
What is the cheapest way to send stablecoins to someone?
On Sui, a direct transfer of a supported stablecoin, which costs nothing. Compare that to the alternatives before you pick a route: a bank wire carries a flat fee and takes days, most blockchains charge a network fee that fluctuates with congestion, and exchanges often add a withdrawal fee on top of the network fee. If the recipient does not have a wallet address yet, a Slush Link is the simpler path and avoids the address-copying step entirely.
Can I send someone crypto with just a link or QR code?
Yes. A Claimable Slush link bundles tokens and NFTs together and produces a link and a QR code you can send however you like. The recipient does not need to give you an address first. The first person to open the link or scan the code claims what is inside, so send it directly to the person it is meant for. You can reclaim the assets at any point before it is claimed, which invalidates the link.
What is the easiest way to send SUI tokens from a phone?
Open the Slush mobile app and tap Send on the Home screen. Then choose one of these:
- Paste the recipient's wallet address
- Enter their SuiNS name
- Scan their QR code
- Create a Claimable Slush link if you do not have an address
Pick the token and amount, review the network fee, and confirm. Sending SUI itself is a normal transaction, so a fee applies. You can pay it in SUI or in a supported stablecoin.
Can I pay gas in USDC instead of SUI?
Yes, in Slush. Since October 2026 you can pay the Sui network fee with supported stablecoins for sends, payments, swaps, staking and unstaking, deposits, and withdrawals. Validators still receive SUI; Slush converts in the background so you never handle it. And on a qualifying stablecoin transfer there is no fee at all. Separately, apps built on Sui can sponsor gas on your behalf, in which case you pay nothing and the app pays in SUI.
