Conversation
Synchronize the frontend ABIs with the refactored Solidity contracts and add new Composed Oracle ABIs. - Add ComposedOracle and ComposedOracleFactory ABIs for upcoming pages. - Add defaultSampleSize to the Oracle constructor and base form inputs. - Change PRICE_DECIMALS to 18 in InteractionClient.tsx to prevent scaling and rendering issues on the explore dashboard. - Replace deprecated readMaxValue/readMinValue with readValueInterval.
Resolve CodeRabbit PR suggestions for base oracle improvements.
- Use parseUnits instead of parseFloat multiplication in price submission to prevent floating-point precision loss at 18 decimals.
- Add regex integer checks on alpha and defaultSampleSize inside constructorArgs to prevent page rendering crashes while typing.
- Enforce step={1} browser suggestions on defaultSampleSize input.
Rename the submission time properties to lastUpdated to sync with the smart contract API update. - Rename lastSubmissionTime to lastUpdated in Oracle.ts and ComposedOracle.ts ABI files. - Update hooks in useOracles.ts to read lastUpdated and output lastUpdated inside the Oracle interface. - Update components/oracle-card.tsx and app/[oracleId]/InteractionClient.tsx to render lastUpdated.
- Add Sepolia factory and composed factory addresses - Fetch composed feeds in useOracles and useOracle hooks - Format composed names dynamically from parent feeds - Configure stable public RPC transports in config.ts

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This change adds Sepolia composed-feed support, but the current implementation may submit prices using an incompatible scale, deploy a different sample size than requested, and hide registry failures behind an empty oracle list. These correctness and availability risks should be fixed before merging. Sequence Diagram(s)sequenceDiagram

The log includes
userAddressand prints it to the browser console on every submission. A wallet address is a user identifier. Log only the values needed for debugging, or remove the log.🧹 Proposed change

277-314: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low valueConsider a cheaper composed-oracle probe.
For a standard oracle, this block issues four reads that all revert before the code selects the standard path. A single probe read, for example
feedA, gives the same signal at one quarter of the RPC cost. LoadfeedB,invertResult, anddefaultSampleSizeonly after the probe succeeds.🤖 Prompt for AI Agents

Inline comments:
In `@app/`[oracleId]/InteractionClient.tsx:
- Line 39: Verify the deployed Oracle contract version and align the frontend
price handling with its actual normalization scale and submitValue(int256) ABI;
update PRICE_DECIMALS and the submission/display types and conversions in
InteractionClient accordingly, preserving correct signed-value behavior.
In `@components/createOracle.tsx`:
- Around line 82-83: Update the defaultSampleSize handling in the createOracle
constructor-argument path to validate and use the same unsigned-integer format
as the later sample-size validation, including canonical decimal input such as
1000 but rejecting non-canonical forms such as 1e3. Do not fall back to 100 for
invalid input; reject it instead, and keep the validated value unchanged.
In `@hooks/useOracles.ts`:
- Around line 61-90: Track whether the standard and composed registry reads in
the oracle-loading flow succeeded, and set the hook error when both reads fail
instead of treating the result as an empty registry. Preserve partial-success
behavior by continuing to use any registry data returned when only one read
fails, and ensure setOracles is not given an empty successful result without an
accompanying error when neither registry responds.
In `@utils/config.ts`:
- Around line 24-33: Update the chain-to-explorer mapping in getBlockExplorerUrl
to handle Sepolia chain ID 11155111 and return its block-explorer URL, so the
“View Transaction” link works after Sepolia deployment.
