Upgrade to v1.3.0 which includes the RaceStrategy implementation using Promise.any() for first-resolved RPC provider selection. Closes openscan-explorer#192 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add race mode that queries all RPC endpoints simultaneously and returns the first successful response, optimizing for latency. Changes: - Add "race" to RPCStrategy type, UserSettings, and RPCMetadata - Extend DataService constructor to accept "race" strategy - Apply maxParallelRequests limit for race mode in useDataService - Add "Race (Fastest)" option to Settings UI with description - Show max parallel requests control when race mode is active - Update RPCIndicator with lightning bolt badge, winner highlight, response time sorting, and race-specific footer note Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Fix two issues with transaction status on the address page: 1. Handle both "0x1"/"0x0" and "1"/"0" receipt status formats in TransactionHistory and AddressDetails components. 2. Add sequential retry for failed receipt fetches in AddressTransactionSearch. When using race/parallel strategies, the high concurrent request volume (batch_size × providers) can trigger RPC rate limiting, causing some receipts to fail. Failed receipts are retried one-at-a-time with delays to avoid the burst that caused the initial failure. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
