Tron to Polygon: TRC-20 and EVM boundary
A Tron source uses a T-address plus bandwidth and energy accounting; TRX covers resource or fee needs for native or TRC-20 transfer execution. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. Tron and Polygon 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.
WETH to DAI representation change
WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. 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. Verify the exact TRC-20 contract and the Polygon representation independently.
Receiving stablecoin DAI
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 destination wallet must support the exact Polygon representation. The route converts a token source into a stablecoin balance; the destination ticker alone is not a contract check.
WETH unwrap or exchange input check
WETH is a contract wrapper for ETH. It can be transferred as a token but cannot replace the native gas balance required by the network. On this route WETH is the source token on Tron. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Mistakes specific to WETH Tron to DAI Polygon
Route-specific mistakes include sending on a network other than Tron; using a destination that is not valid for Polygon; running out of TRX before the source transaction is submitted; assuming other and evm addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract; treating a wrapped token as the native gas asset.

WETH input identity and handling
WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Tron. The recorded Tron representation uses 18 decimal places. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer.
DAI output identity and receiving
Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on Polygon. The recorded Polygon 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.
