eth_call on HyperEVM
Executes a message call against the EVM without creating a transaction — the backbone of every contract read (balanceOf, totalSupply, etc.). Returns the call's return data.
Runs against a chosen block's state with no gas paid; override from/value/block to simulate a sender or a past state. It surfaces the contract's revert reason, which is how you catch errors like 'insufficient allowance' before sending a real tx.

Contract calls on HyperEVM
Standard EVM semantics apply. Contracts that bridge into HyperCore (spot/perp state) use special precompile addresses — regular eth_call works on them like any other contract.

eth_call on HyperEVM — FAQ
How do I call eth_call on HyperEVM?
POST a JSON-RPC 2.0 request with "method": "eth_call" to NodeFlare's HyperEVM endpoint at https://rpc.nodeflare.app/hl/public. No API key is required for the public endpoint.
What does eth_call cost on the free tier?
eth_call is weighted at 5 compute units per call. The free tier includes 2,000,000 CU/month, so that is roughly 400,000 eth_call calls per month — no credit card.
Is eth_call available on the public HyperEVM endpoint?
Yes. eth_call works on the public HyperEVM endpoint (https://rpc.nodeflare.app/hl/public) with no API key, rate-limited per IP. A free key adds higher limits and a dedicated path.
Anything HyperEVM-specific to know when using eth_call?
Standard EVM semantics apply. Contracts that bridge into HyperCore (spot/perp state) use special precompile addresses — regular eth_call works on them like any other contract.
