cBridge APIs for Sui
The Sui platform seeks to provide a flexible network that you can leverage to shape the web3 landscape, which is derived from the core Move programming language. If you want to learn more about Sui, please refer to the official document here https://docs.sui.io/learn. Here is the guideline on how to integrate the Sui chain and support the Sui asserts bridge via cBridge from the front-end perspective.

Bridges
In most scenarios Sui is the pegged chain, the token is bridged from the other chains like Ethereum. All support tokens you can get from the JSON path “pegged_pair_configs” at this link:https://cbridge-prod2.celer.app/v1/getTransferConfigsForAll(testnet: https://cbridge-v2-test.celer.network/v1/getTransferConfigsForAll)
For example, consider a bridge pair {fromChain: Ethereum Mainnet, toChain: Sui Mainnet, Token: USDC}
. Ethereum Mainnet serves as the original chain, while Sui Mainnet acts as the pegged chain. To bridge USDC from Ethereum Mainnet to Sui, you need to interact with the Ethereum Mainnet Vault contract to deposit the USDC. Once the deposit on the source chain is received and verified by the SGN (State Guardian Network), the USDC will be minted on the destination chain shortly after. If you wish to bridge the USDC back to Ethereum from Sui, you can call the burn method on Sui to burn the USDC tokens on-chain. This process ensures a similar level of safety when withdrawing the tokens back to Ethereum.
Get tokens balance
Get SUI (gas token) balance
For other tokens
Note that Sui stores the token information in split objects. Therefore, it is necessary to merge all the split objects into a single base object to ensure a sufficient balance for later bridging.
Quote the bridging fees
Use the cBridge quote API to get the estimated received amount and fees,
Refer to this doc:
https://cbridge-docs.celer.network/developer/api-reference/gateway-estimateamt
Sui Token burn
Used for burning a token on Sui when Sui is a pegged chain.
Example code:
Note that as opposed to the
mergeCoin
method, before the transaction happened, you must split the coin into different objects first.
Nonce
: uniq for the transaction, you can also use the timestamp as the nonce.
mintTcId
: get the mintTcId from this code
Query bridge status from SGN
cBridge allows tracking the status of the bridge at each stage. You can retrieve this information using the getTransferStatus API. For more details, please refer to the documentation at: https://cbridge-docs.celer.network/developer/api-reference/gateway-gettransferstatus.
The transferId
is designed to generate a unique identifier for tracking the states. However, it's important to note that the rules for Sui differ from those of other chains.
You can get the sourceTokenAddress,peggedBurnContractAddress
from the getTransferConfigsForAll
Bridging Limits
Get token burn minimum/maximum amount.
The token the user burn shouldn’t exceed the total supply, the method of getting the total supply.
