Nodit now supports the eth_simulateV1 API.
Major Updates
eth_simulateV1 API Support
The eth_simulateV1 API is a JSON-RPC API that simulates the execution of multiple transactions across one or more blocks in advance, without actually executing them. It is similar to eth_call, but differs in that it lets you run a sequence of calls with the block context and account state overridden with arbitrary values.
Among the blockchains supported by Nodit, the following chains support eth_simulateV1.
| chain | network |
|---|---|
| Arbitrum | mainnet, sepolia |
| Arc | testnet |
| Bnb | mainnet, testnet |
| Base | mainnet, sepolia |
| Ethereum | mainnet, sepolia, hoodi |
| Giwa | sepolia |
| Optimism | mainnet, sepolia |
| Metal | mainnet |
| Polygon | mainnet |
