Guides
Guides for common Polygon RPC issues
These guides are built for builders, bots, and operators who need to understand whether the pain is coming from request shape, shared infrastructure constraints, stale reads, or a real application issue.
Buyer guide for Polygon RPC selection
Use a practical framework for deciding when shared access is enough and when an authenticated managed Polygon RPC plan becomes the better fit.
Fix Polygon RPC 429 errors
Understand when bursty request patterns, shared contention, or hidden throttling are driving repeated 429s.
Diagnose Polygon RPC timeouts
Timeouts often look like application instability when the real issue is upstream variance, overload, or stale endpoint behavior.
Investigate slow Polygon RPC behavior
Not all RPC pain is a hard failure. Slow reads and tail latency can quietly make production workflows unreliable.
Fix Polygon eth_getLogs timeouts
Chunk broad log scans, narrow filters, and separate backfill from live polling before you blame your app.
Understand Polygon trace and debug API costs
Trace-heavy workloads need more than RPS headlines. They need method support and cost clarity.
Fix Polygon WebSocket disconnects
Prevent dropped subscriptions and silent socket termination during high-frequency block header events.
Fix inconsistent bot & DEX behavior
Eliminate multi-node state drift, tip-of-chain desynchronization, and mempool eviction for automated trading.
Avoid silent scraper throttling
Diagnose unannounced artificial latency increases and optimize batch ingestion for indexing pipelines.
Handle Polygon reorgs & missing logs safely
Use safe block confirmation tags and rollback buffers to prevent indexing stale or reverted transactions.
Unstick pending & stuck transactions
Clear nonce sequence gaps and dynamically calculate EIP-1559 priority fees during congestion.
Migrate from Alchemy, QuickNode, or Infura
Translate confusing compute unit multipliers to simple, flat monthly request allowances in 60 seconds.
Measure before you change providers
The Proof Hub explains what the public measurements cover and where their limits are. Use it alongside the specific guide for your failure mode.
