Arbitrum to Tron: TRC-20 and EVM boundary
On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. A Tron receipt belongs to a T-address as native TRX or the quoted TRC-20 contract; later activity consumes Tron resources or TRX fees. Arbitrum and Tron use different network identities, gas assets, wallet support, confirmation behavior, and destination conventions. Validate each side independently in the current route.
TRX resources and Tron address check
TRX is the native gas asset for Tron. Tron Base58Check address, commonly beginning with T A TRC-20 token transfer is not an ERC-20 transfer even when an asset ticker exists on both sides.
DAI to USDC representation change
DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset. Verify the exact TRC-20 contract and the Arbitrum representation independently.
DAI and USDC: 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. USDC is an issued dollar-oriented stablecoin with canonical, native, and bridged variants across networks. Contract events and issuer controls differ from a network-native gas asset. The route changes both asset identity and network representation; dollar-oriented pricing does not remove issuer controls, liquidity spread, contract, or receiving-network checks.
Mistakes specific to DAI Arbitrum to USDC Tron
Route-specific mistakes include sending on a network other than Arbitrum; using a destination that is not valid for Tron; 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. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval.

DAI input identity and handling
Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on Arbitrum. The recorded Arbitrum 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.
USDC output identity and receiving
USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on Tron. The recorded Tron representation uses 6 decimal places. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
