The swap decoder read no recipient, so a swap paying its output to another
address still showed Min. received. It now reads the recipient of every swap
step, SWEEP, UNWRAP_WETH, V4 TAKE and TAKE_ALL, reads the router's
placeholders as the router does (address(1) is the sender, address(2) the
router, which holds the output until a later SWEEP or UNWRAP_WETH pays it
out), and compares the result with the transaction's sender. When the output
goes anywhere else, a Paid to line names each address it is paid to and the
minimum reads Min. paid out. The approval and transaction detail screens pass
the sender in.

The Universal Router decoder recognised execute() by its selector alone, so
the same calldata sent to any address was described as a swap through the
router. It now keeps the router deployments Uniswap publishes for Ethereum
Mainnet and Sepolia, and decodes only a transaction sent to one of them on
its network, ignoring address case. TxApproval passes the transaction's
chain id, TransactionDetail the active network's.

A V4 swap could set minOutput while leaving outputToken null, and tokenInfo(null) returned ETH at 18 decimals, so the approval screen named an asset the calldata never stated. Established from the V4 encoding that this is wrong rather than protocol semantics: Currency is a user-defined value type over address, so native ETH arrives as the truthy zero-address string and is already mapped to ETH, and an UNWRAP_WETH output is caught earlier — both genuine native-ETH routes are covered without null, so null can only mean no sub-action yielded a currency. A genuine native-ETH V4 swap still renders as ETH, pinned by test against the real mainnet fixture.
The same gate also let a later step overwrite minOutput while an earlier hop's outputToken stayed on screen, showing a figure against the wrong token. Fixed together as the same two lines and the same defect.
