The native Sui Bridge token list is specific: ETH, WETH, USDT, WBTC, and LBTC appear in the current Ethereum↔Sui interface. Each asset has a distinct Ethereum origin, Sui coin type, decimal behavior, and application-liquidity profile. A familiar ticker is not enough to identify the received asset.
Review the current Sui Bridge token route and verify the live selector before approving any Ethereum contract.
Does Sui Bridge support native ETH?
Yes. Native ETH can be deposited directly on Ethereum and represented as Sui Bridge ETH on Sui. The bridge’s 2024 mainnet launch article made ETH the central launch asset.
The destination asset must be distinguished from Wormhole WETH and other wrapped Ether coins already present in the Sui ecosystem.
Does it also support WETH?
Yes. The current interface lists Ethereum WETH separately from native ETH. WETH requires ERC-20 allowance approval before the bridge call, while native ETH is transferred as transaction value.
On Sui, ETH delivered by the native route and WETH delivered through another bridge can have different coin types and liquidity pools even when both track Ether.
Is USDT available on the native bridge?
Yes. The current interface lists Ethereum USDT and publishes the Ethereum contract address in its FAQ. Because USDT uses six decimals, the smallest displayed bridge unit differs from ETH and WETH.
USDT approval behavior also deserves attention: some interfaces may reset an existing allowance before setting a new one. Users should distinguish allowance transactions from the actual bridge deposit.
When was WBTC added?
Sui announced native WBTC bridge support in February 2025. The official WBTC release framed the route as a way to bring Ethereum WBTC into Sui BTCfi applications.
The received Sui Bridge WBTC is not native Bitcoin. It remains a representation of WBTC that originated on Ethereum.
What is LBTC on the Sui Bridge interface?
LBTC appears in the current token selector as a separate Bitcoin-linked asset. It is not interchangeable with WBTC merely because both reference Bitcoin. The Ethereum token, Sui coin type, custody model, bridge capacity, and supported applications must be verified independently.
The interface can enforce a route-specific LBTC vault or balance limit in addition to the global bridge limiter.
Does the native panel support USDC?
USDC is not part of the current native lock-and-mint token selector. Sui integrated Circle’s Cross-Chain Transfer Protocol for native USDC transfers, but CCTP burns USDC on the source and mints native USDC on Sui rather than using the Sui validator bridge token list.
Circle’s current documentation lists Sui under CCTP V1 legacy domains and publishes the canonical Sui USDC coin type.
Can the SUI token itself be bridged to Ethereum?
The current native token selector does not list SUI as a transferable asset. A query such as “bridge SUI to ETH” may actually mean exchanging SUI for ETH, using a third-party route, or withdrawing an ETH representation from Sui.
Users should not assume that choosing Sui as the source chain makes every Sui coin eligible for the native bridge.
What precision rules affect ETH and WETH?
The live bridge FAQ states that ETH and WETH are handled with eight decimal places of precision. Values smaller than 0.00000001 ETH cannot be represented in the bridge amount, and extra precision can be rounded down.
For example, a value such as 10.0000000000000001 ETH is described as rounding to 10 under the bridge’s reduced precision. This matters for balance reconciliation.
What precision applies to USDT?
USDT uses six decimal places, so the smallest stated bridge unit is 0.000001 USDT. The token’s Ethereum decimals, bridge message amount, and Sui coin balance should agree after conversion.
Unexpected rounding should be checked against the precision rule before being reported as a missing balance.
How should token identity be recorded?
| Asset | Ethereum form | Destination check |
|---|---|---|
| ETH | Native transaction value | Sui Bridge ETH coin type and balance |
| WETH | ERC-20 WETH | Sui Bridge WETH/ETH mapping shown by route |
| USDT | Ethereum ERC-20 | Sui Bridge USDT coin type and six decimals |
| WBTC | Ethereum WBTC | Sui Bridge BTC coin type and supported app |
| LBTC | Ethereum LBTC | LBTC-specific Sui coin type and vault capacity |
Which asset should a user choose?
Choose the asset that the destination Sui application explicitly supports, not whichever ticker looks closest. Confirm the Sui coin type, available liquidity, intended use, and return path. A technically successful bridge can still deliver a coin that the destination market does not use.
