eth_call - Bittensor RPC Method
Execute smart contract calls without creating transactions on Bittensor. Essential for reading contract state for decentralized AI inference, subnet-specific AI models, TAO staking, and cross-subnet AI collaboration.
Executes a new message call immediately without creating a transaction on Bittensor. Used for reading smart contract state.
Why Bittensor? Build on the decentralized machine intelligence network built around subnets, TAO staking, and validator-miner coordination with Yuma Consensus, subnet-based specialization, dual Substrate and EVM surfaces, and onchain incentive coordination.
Use Cases
The eth_call method is essential for:
- Reading contract state - Query view/pure functions
- Simulating transactions - Test execution without gas costs
- DeFi integrations - Check prices, balances, allowances for decentralized AI inference, subnet-specific AI models, TAO staking, and cross-subnet AI collaboration
- Complex queries - Execute multi-step contract logic
Code Examples
Error Handling
| Error Code | Message | Description |
|---|---|---|
| -32000 | Execution reverted | Contract function reverted |
| -32602 | Invalid parameters | Invalid data encoding |
| -32015 | VM execution error | Contract logic error |

eth_sendTransaction
Send a transaction from an unlocked account on Bittensor. Requires the node to hold the sender's private key — intended for development and testing only.
eth_getLogs
Query event logs on Bittensor. Essential for indexing decentralized AI inference, subnet-specific AI models, TAO staking, and cross-subnet AI collaboration on the decentralized machine intelligence network built around subnets, TAO staking, and validator-miner coordination.
