Implements the error class hierarchy used by external API adapters (Moralis/Alchemy) to classify failures for circuit breaker and failover decisions. Includes 7 AdapterError subclasses with isBreakerable flags plus AllProvidersUnavailableError for orchestrator. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…i-provider failover Implements CircuitBreaker class with composite key (chain:network:provider), configurable failure thresholds (consecutive + rate-based), timeout-driven HALF_OPEN probing with in-flight permit tracking, and metrics reporting. Includes 36 comprehensive unit tests covering all state transitions. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…th sequential failover Implements the core orchestrator that wires adapters + circuit breakers + sequential failover for multi-provider EVM transaction lookups, address streaming, and wallet streaming. Key features: - Per-network provider arrays with independent circuit breakers - withBreakerAttempt helper guaranteeing permit release on any throw - Preflight stream check buffering first item before committing to a provider - Floor semantics enforcement via RPC for adapter block-by-date results - Public getTransaction override letting AllProvidersUnavailableError and InvalidRequestError propagate for correct HTTP 503/400 mapping - Provider ordering by priority ascending, then name lexicographically - getBlockBeforeTime override using indexed API providers instead of Bitcoin collections Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Registers MultiProviderEVMStateProvider as CSP with EVMRouter and MoralisP2PWorker. Activated by setting module: './multiProvider' in bitcore chain config. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…error logging Prevent API keys (e.g. Alchemy v2/v3 path keys, query param keys) from appearing in error logs by redacting them before they are stored in err.log objects. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
