Frequently Asked Questions
What chains does Tokenview API support?
We cover all major EVM chains, Bitcoin forks, Cosmos SDK networks, and emerging Layer2 solutions. New chains are added biweekly.
How accurate is the blockchain data?
All data undergoes cryptographic verification against multiple node sources before API delivery.
Can I deploy contracts through the API?
Yes. Our write-enabled endpoints support contract creation and method calls without running full nodes.
Is there rate limiting?
Free tier includes 5 requests/second. Enterprise plans offer customizable throughput.
How quickly is new block data available?
Most chains reflect new blocks in <15 seconds. Real-time websocket connections are available.
