图例解释：❌ = 不支持。 🚧 = 开发中。 ✅ = 已支持。
备注
eth_sendRawTransactionsupports legacy(EIP-155), type-1(EIP-2930) and type-2(EIP-1559) transactions. Type-3 transactions (EIP-4844) transactions are not supported yet.- 此处未列出的方法也不支持。
- 没有所谓的 uncle（又称 ommer）区块。
eth_getUncleByBlockHashAndIndex和eth_getUncleByBlockNumberAndIndex方法总是返回null。eth_getUncleCountByBlockHash和eth_getUncleCountByBlockNumber方法对有效的区块 ID 返回零，对无效的区块 ID 返回null。 此外，与 uncle 相关的区块元数据如sha3Uncles是空的哈希数组 sha3。 - 目前不支持非标准的 Geth 跟踪 API
- 非标准 Parity 跟踪 API 正在开发中
extra burntGasFee field of transaction receipts
The implementation of 1559 in Conflux eSpace differs slightly from Ethereum. The base fee of the transaction is not entirely burned; instead, it is partially burned according to a certain ratio, with the remaining part still serving as the miner's revenue. An additional field burntGasFee is added to the transaction receipt (e.g. got from eth_getTransactionReceipt RPC) to record the amount of fees that is burned.
For more information, please refer to CIP-137.
pending 标签
仅 eth_getTransactionCount 方法支持pending 标签。 其他方法将 pending 标签视为latest
- eth_getTransactionCount ✅
- eth_getBalance
- eth_getCode
- eth_getStorageAt
- eth_call
注意：过滤相关的方法也不支持 pending 标签
