USDT and DAI: two stablecoin ledgers

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. 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 route changes both asset identity and network representation; dollar-oriented pricing does not remove issuer controls, liquidity spread, contract, or receiving-network checks.

USDT input identity and handling

Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on Scroll. The recorded Scroll representation uses 6 decimal places. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior.

DAI output identity and receiving

Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on Linea. The recorded Linea representation uses 18 decimal places. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

Scroll to Linea L2 handoff

This route crosses two L2 execution environments. Scroll settles to ethereum, while Linea 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.

Linea destination execution

Linea is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Linea. EVM 0x account address A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract.

Mistakes specific to USDT Scroll to DAI Linea

Route-specific mistakes include sending on a network other than Scroll; using a destination that is not valid for Linea; 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. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

Private Route for USDT → DAI

Scroll wallet, token-transfer, contract, log, and gas activity remain public, and Linea wallet, token-transfer, contract, log, and gas activity remain public. For this USDT on Scroll to DAI on Linea 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.
