Conversation
- Added support for HyperFX in the bridge functionality, allowing same-chain swaps between USDC/USDT and cNGN. - Updated configuration to enable HyperFX with a new environment variable. - Enhanced bridge components to handle HyperFX quotes and transactions. - Introduced new utility functions for fetching HyperFX bundler URLs and managing HyperFX-specific logic. - Updated types and interfaces to accommodate HyperFX integration across the application.

The change adds quote and status APIs, wallet execution, bundler resolution, UI integration, caching, analytics, tests, and transaction persistence. HyperFX bridge integration
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The current change can report a conversion as completed before funds are filled, or leave reverted or terminal orders showing as processing. That creates material transaction-status correctness risk for users, so the PR should not merge until these cases are fixed or explicitly accepted by the owner. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@app/api/bridge/hyperfx/quote/route.ts`:
- Around line 146-147: Update the chainId parsing near chainIdParam so an absent
chainId parameter uses the 8453 default instead of converting null to 0;
preserve numeric values and default non-numeric inputs as before.
- Around line 192-199: Update the catch block in the HyperFX quote route to
retain server-side logging of the original error while returning a fixed generic
error message to clients; remove the err.message-based response and preserve the
existing 502 status and tracking behavior.
- Around line 155-163: Update the fee calculation near amountOutFormatted so
feeRaw is converted from input-token units to receiving-token units for both
cNGN directions, using the quote’s amountIn and amountOut scaling consistently.
Replace the hardcoded toDecimals with the destination token’s actual decimals,
and use those decimals for both amountOutFormatted and feeFormatted.
- Around line 79-80: Validate fromDecimals in the quote route before it reaches
parseUnits: require a finite integer within the supported decimal range,
otherwise reject the request or use the resolved token’s decimals. Ensure
invalid values such as non-numeric input cannot produce amountIn, and prevent
client-supplied values from incorrectly scaling rawAmountIn used by the HyperFX
on-chain flow.
- Around line 125-136: Update the HyperFX quote flow around
IntentsCoprocessor.connect and Promise.race to retain the timeout handle, clear
it once the race settles, and disconnect the coprocessor in the quote promise’s
finally block. Ensure cleanup runs for both successful and failed or timed-out
requests.
In `@app/api/bridge/hyperfx/status/route.ts`:
- Around line 38-47: Update the transaction status flow after
client.getTransactionReceipt in the route handler to return { status: "FAILED",
txHash } immediately when receipt.status is "reverted", before filtering logs or
parsing OrderPlaced. Add a route test covering the reverted-receipt response.
In `@app/components/bridge/BridgeQuoteCard.tsx`:
- Around line 142-147: Update the countdown effect in BridgeQuoteCard to handle
hyperfx-intent quotes alongside near-deposit, using the quote’s expiresAt value
so secondsLeft updates and onExpire fires when the quote expires. Preserve the
existing behavior for other quote kinds.
In `@app/lib/bridge.ts`:
- Around line 596-609: The terminal-status cache writes in the bridge response
handling must not alter the API result when sessionStorage is unavailable. Wrap
the sessionStorage setItem/removeItem operations in a local try/catch, swallow
storage failures, and ensure the surrounding flow still returns data for
SUCCESS, FAILED, and REFUNDED responses; add a test covering
sessionStorage.setItem throwing.
In `@app/lib/hyperfx.ts`:
- Around line 222-230: In app/lib/hyperfx.ts lines 222-230, update the
BID_SELECTED branch so it no longer calls markHyperfxTerminal with "settled";
keep consuming the iterator and mark settlement only on FILLED or a SUCCESS
result from resolveHyperfxOnChainStatus. In app/hooks/useBridgeStatusTracker.ts
lines 99-101, verify the HyperFX branch reaches completed only after confirmed
fill and still observes REFUNDED and FAILED after bid selection.
- Around line 478-503: Update the order construction so output.assets[0].amount
does not require the exact five-minute-old quote amount: re-quote through the
gateway immediately before creating the order, or apply the configured slippage
to the requested output amount, while preserving the existing token and
beneficiary fields.
- Around line 515-519: Update the public client initialization near
createPublicClient to reuse createNetworkPublicClient(quote.network), ensuring
waitForTransactionReceipt receives a client configured with the resolved viem
base chain; remove the chain.config cast and avoid constructing the client from
the Hyperbridge SDK configuration.
- Around line 621-625: Move post-placement executeBest consumption out of the
browser session: persist the order and hand it to a server-side or worker
process that continues consuming the async generator after navigation or tab
closure. Update trackHyperfxFillInBackground and the placement flow around
executeBest so auction bid selection and fill execution continue independently,
while preserving the returned placement transaction data.
In `@app/lib/hyperfxStatus.ts`:
- Around line 112-114: The storage-confirmed branch in the order status flow
should call findOrderFilledTxHash before returning SUCCESS and use its result as
fillTxHash. When no fill-event transaction is found, omit both fillTxHash and
destinationTxHash without falling back to placementTxHash or txHash, and add a
regression test covering this behavior.
- Around line 62-66: Update the getLogs call in the pending-status polling flow
to apply RPC-side filtering using the OrderFilled event ABI and the indexed
commitment argument, while preserving the existing gateway, fromBlock, and
latest-block range. Ensure parseEventLogs receives only matching logs rather
than filtering the full gateway response locally.
In `@next.config.mjs`:
- Around line 8-11: Remove ALCHEMY_API_KEY from the next.config.mjs env
configuration so the unrestricted server key is not embedded in browser bundles.
If client-side HyperFX requires a public key, use NEXT_PUBLIC_ALCHEMY_API_KEY
instead and ensure it is restricted to Base, required RPC methods, and approved
browser origins.

Description
Adds HyperFX (Hyperbridge IntentGateway) as a bridge engine in Noblocks Convert, enabling same-chain USDC/USDT ↔ cNGN swaps on Base (chain ID 8453).
Routing: For eligible pairs on Base, Noblocks tries HyperFX first; all other Convert legs keep existing behavior (LI.FI for cross-chain / unsupported pairs, NEAR Intents for EVM↔EVM stables).
