DAI and USDT: two stablecoin ledgers

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. USDT is issued through ERC-20, TRC-20, SPL, and other network-specific contracts. The ticker does not determine the token standard, contract, issuer controls, or destination address model. The route changes both asset identity and network representation; dollar-oriented pricing does not remove issuer controls, liquidity spread, contract, or receiving-network checks.

DAI input identity and handling

Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on Scroll. The recorded Scroll 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.

USDT output identity and receiving

Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on zkSync Era. The recorded zkSync Era representation uses 6 decimal places. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Scroll to zkSync Era L2 handoff

This route crosses two L2 execution environments. Scroll settles to ethereum, while zkSync Era settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.

Scroll source execution

Scroll is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Scroll. EVM 0x account address A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently.

zkSync Era destination execution

zkSync Era is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on zkSync Era. EVM 0x account address A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.

Mistakes specific to DAI Scroll to USDT zkSync Era

Route-specific mistakes include sending on a network other than Scroll; using a destination that is not valid for zkSync Era; running out of ETH before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Private Route for DAI → USDT

Scroll wallet, token-transfer, contract, log, and gas activity remain public, and zkSync Era wallet, token-transfer, contract, log, and gas activity remain public. For this DAI on Scroll to USDT on zkSync Era path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side EVM 0x account address; it does not hide either chain's public records.

What changes between the source and destination asset roles?

DAI is the deposited stablecoin input; USDT is the quoted stablecoin 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 Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently.

Which stablecoin contract must this route match?

DAI must match its Scroll representation. USDT must match the quoted zkSync Era representation. A ticker or target price is not enough to identify a token contract.

ETH is the native gas asset for Scroll. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. DAI is token-tracked and can need approval before transfer.
