以以太坊的ERC20接口为例,接口有一个描述字:constant。 带constant的函数,web3会自动使用eth_call远程调用。 不带constant的函数,web3使用eth_sendTransaction远程调用。 比如查询地址余额的函数balanceOf带有constant描述字,web3会使用eth_call远程调用。 2)eth_sendTransaction调用过程 eth_sendTransaction调用发起一笔交易...
gas: QUANTITY - 交易可用gas量,可选。eth_call不消耗gas,但是某些执行环节需要这个参数 gasPrice: QUANTITY - gas价格,可选 value: QUANTITY - 交易发送的以太数量,可选 data: DATA - 方法签名和编码参数的哈希,可选 QUANTITY|TAG - 整数块编号,或字符串"latest"、"earliest"或"pending" ...
Infura为每个eth_call调用eth_getBlockByNumber十次是指在使用Infura提供的API进行以太坊智能合约调用时,每次调用eth_getBlockByNumber方法会被Infura节点执行十次。eth_getBlockByNumber是以太坊的JSON-RPC接口之一,用于获取指定区块号的区块信息。 这种做法的目的是为了提高调用的可靠性和准确性。由于以太坊网络的...

The document describes the eth_callMany API method, which allows for simulating transaction bundles without creating transactions on the blockchain, useful for understanding potential outcomes and testing sequential dependencies. It supports overwriting
In comparing a revert error from an eth_call between nodes, I noticed that Geth returns a generic(?) error code during a revert. Where as Nethermind returns a specific error code, and I THINK Parity/OpenEthereum is also returning the same error code as Nethermind. I'm wondering why Geth...
