Base to Sui: object and account boundary

A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Base and Sui use different network identities, gas assets, wallet support, confirmation behavior, and destination conventions. Validate each side independently in the current route.

Sui coin-object and SUI gas requirements

SUI is the native gas asset for Sui. Sui hexadecimal account address with an object-based asset model Coin objects and Move types are not EVM token contracts.

DAI input versus ETH output representation

DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

Converting stablecoin DAI into ETH

DAI is a crypto-backed dollar-oriented stablecoin whose canonical and bridged contracts vary by network. Its peg design does not make two network representations interchangeable. The source is a stablecoin contract or recorded native representation, while ETH is classified as native-asset. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.

Mistakes specific to DAI Base to ETH Sui

Route-specific mistakes include sending on a network other than Base; using a destination that is not valid for Sui; running out of ETH before the source transaction is submitted; assuming evm and other addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

DAI input identity and handling

Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on Base. The recorded Base representation uses 18 decimal places. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical.

ETH output identity and receiving

Ethereum is classified as a native asset for this route. ETH uses a network-specific contract asset on Sui. The recorded Sui representation uses 8 decimal places. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

Private Route for DAI → ETH

Base wallet, token-transfer, contract, log, and gas activity remain public, and Sui account, object, transaction-effect, and fee activity remain public. For this DAI on Base to ETH on Sui path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side Sui hexadecimal account address with an object-based asset model; it does not hide either chain's public records.

Swap DAI on Base to ETH on Sui FAQs

How does the Sui coin-object side differ from the other network?

Sui uses Move coin types and objects with SUI gas. The other side follows EVM execution, so addresses and token identifiers are not interchangeable.

What exactly leaves Base as DAI?

DAI is a contract representation on Base with 18 decimals at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb. ETH, not DAI, pays gas unless both symbols are the same. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical.

What exactly arrives on Sui as ETH?

ETH is a contract representation on Sui with 8 decimals at 0xd0e89b2af5e4910726fbcd8b8dd37bb79b29e5f83f7491bca830e94f7f226d29::eth::ETH. SUI, not ETH, pays gas unless both symbols are the same. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

Why does the DAI to ETH direction matter?

DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. On receipt, Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

What changes between the source and destination asset roles?

DAI is the deposited stablecoin input; ETH is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.

What should be matched before sending DAI?

DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

Which stablecoin contract must this route match?

DAI must match its Base representation. A ticker or target price is not enough to identify a token contract.

Can I swap DAI on Base to ETH on Sui without KYC?

Requirements are checked for the live DAI Base to ETH Sui quote. Verification requirements can depend on the provider, amount, jurisdiction, and current route. Sasquatch does not verify this route as universally no-KYC; check the live flow before continuing.
