fix(swapper): read 0x NATIVE_CHECK and Relay order deadlines onto quotes - #12767
Merged

Conversation
0x native sells carry no Permit2 message, but Settler reverts with SignatureExpired past the NATIVE_CHECK deadline in the calldata. Decode the first Settler action and set it as the quote deadline so expired native quotes are rejected before signing, like Permit2 quotes already are. Relay cross-chain orders expire at protocol.v2.orderData.output.deadline, after which the solver submits a no-fill refund. Type the order data and set that deadline on the quote. Same-chain Relay swaps have no protocol block and stay without one. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

A rabbit checked the quote at dawn
And found a deadline tucked upon
Through Relay fields and calldata
The time was passed along, hooray
Then hopped away before the dawn

undefined and null values are treated as absent before calling
normalizeEpochToMs; preserve normalization for non-null deadlines.

- Line 17: Update the native-check deadline selection in

and use the earliest deadline, rather than taking the first match.

Description
Follow-up to #12761 (reject expired 0x Permit2 quotes) and #12753 (optional
TradeQuote.deadline). Two swappers were still dropping a deadline the provider enforces:0x native sells. Native sells have no Permit2 message, so
deadlinewas left undefined. Settler's first action on a native sell isNATIVE_CHECK(uint256 deadline, uint256 msgValue)and revertsSignatureExpiredpast it (fetch + 5 min live, same window as Permit2). NewgetZrxNativeCheckDeadlinedecodes the Settlerexecutecalldata and reads it. Permit2 quotes keep the message deadline and are not decoded, since that calldata is not valid until the signature is spliced in. Calldata without a NATIVE_CHECK action (e.g. a WETH unwrap) stays without a deadline. The Permit2 validity check is shared with the new path.Relay cross-chain.
protocol.v2.orderDatawas typedunknown. It carriesoutput.deadline(unix seconds, fetch + 7 days live), after which the solver submits a no-fill refund (PROTOCOL_DEADLINE_EXPIRED). It is now typed and set on the quote throughnormalizeEpochToMs. Same-chain Relay swaps have noprotocolblock and no enforced deadline, so they stay undefined.Portals and Symbiosis are deliberately unchanged: neither response exposes a deadline field, and the routed DEX varies, so nothing is inferred from calldata.
Issue (if applicable)
closes #
Risk
Low. No transaction construction changes. Only
TradeQuote.deadlineis populated on two more paths, which the web sign gate and the public-apiexpiresAtalready consume. Worst case of a wrong value is a quote being rejected before signing, never a different on-chain tx.0x native-asset sells on all 0x chains and Relay cross-chain quotes.
Testing
Engineering
Unit:
getZrxTradeQuote.test.tsadds a case using live Settler calldata from an ETH -> USDC sell (expects1791997786000) and keeps the no-NATIVE_CHECK case undefined.Live, through
getSwapperDeps()from the public-api with the real swapper code:Operations
Quote a native sell via 0x (e.g. ETH -> USDC) and wait past 5 minutes on the confirm screen: signing should be rejected as expired rather than submitting a tx that reverts.
