@SuiNetwork As builders on Sui, we want the first deposit to feel as simple as the first trade. This is a welcome step.

@SuiNetwork Let's get the burn and mint me mechanism started!!! This is a great feature, esp for the new agentic economy coming.

High attention and emotional sentiment detected.
The Sui Foundation announced the launch at 06:52 UTC on Wednesday through its @SuiNetwork account. Mysten Labs amplified it minutes later. Circle then confirmed the move in its own developer release notes the same day.
Native USDC is not new here. Circle first launched it on Sui back in October 2024. What shipped now is canonical CCTP V2, the transfer rail itself.
Sui sits at CCTP domain 8. The upgrade moves the chain from the older V1 route set to Circle’s current standard. So this is a plumbing upgrade, not the debut of native USDC.
The protocol burns USDC on the source chain first. Circle’s attestation service then signs that the burn happened. Finally, Circle mints the same amount of native USDC on Sui.
Circle’s documentation now lists Sui mainnet and testnet contracts for the protocol. The core packages already sit on-chain under domain 8.
Sui has a long CCTP history. Circle brought V1 to the chain in December 2024, across nine supported chains at the time.
V2 then launched broadly in March 2025. Circle later said canonical contracts still missed Aptos, Noble, and Sui, with a mid-2026 target.
Aptos crossed over in August 2026. Sui followed on Wednesday, just past that window. So Sui was an early V1 chain but a late V2 one.
A bridge usually locks your USDC on one chain. Then it issues a wrapped token on the other. That wrapped token depends on the bridge’s own custody.
CCTP works differently. It destroys the source USDC and creates fresh native USDC under Circle’s own minter. So the token you receive is the same USDC already used on that chain.
The total USDC supply does not grow either. It simply moves. Circle holds mint authority on Sui, so the coins come straight from the issuer.
Bridged / wrapped USDC vs. native USDC via CCTP on Sui
Chain-count note: Circle also lists BNB Smart Chain for USYC only, so it should not be counted as a USDC route.
Sui says native USDC can now reach 29 other supported blockchains. That number is Sui’s figure, though, not an official Circle count.
Circle’s own domain table actually lists more than 29 chains alongside Sui. It also flags BNB Smart Chain as USYC-only, so that route should not count as a USDC path.
Early wire coverage simply repeated the 29-chain line too. Outlets like Odaily and BlockBeats restated Sui’s post without reconciling Circle’s longer table.
In short, the exact live USDC route list stays unresolved for now. Circle has not published a Sui-specific route matrix yet. So treat the 29 figure as a headline, not a verified tally.
Sui already carried two kinds of USDC. Native USDC is Circle-issued and redeemable 1:1 through Circle Mint.
Wormhole’s bridged wUSDC is a separate asset. Circle does not issue it, and Circle Mint does not redeem it. The two tokens also use different coin types on Sui.
Circle flagged this gap back in 2024. No wUSDC migration path arrived with today’s launch. So holders should still check exactly which token they hold.
Standard transfers on Sui are free. Circle lists Sui at 0 basis points on its fee page.
CCTP V2 also offers a Fast Transfer option on some chains. On Sui, though, Circle marks it N/A. The standard path is already quick enough there, so a fast lane would add little.
Fees can still change later. Circle notes that its schedules are subject to change. So builders should check the live table before routing large flows.
The news did not move the market. SUI traded near $1.13 on Wednesday, down about 1% over 24 hours, according to The Defiant.
On-chain supply looked flat too. DefiLlama put Sui’s stablecoin cap near $484 million, with USDC around $306 to $309 million and no visible post-launch jump.
So the launch reads as infrastructure, not a price catalyst. Any adoption effect would likely show up later, in transfer volume rather than SUI’s chart.
Circle still has open questions to settle. It has not confirmed whether Hooks, the post-mint automation feature, run in production on Sui yet.
The bigger test is usage. Payments apps and treasury tools can now build around native USDC on Sui without designing around a bridge.
For now, CCTP V2 on Sui gives builders a cleaner rail and one less wrapped-token headache. So watch the route matrix and transfer volume for the real signal.
