Call, Estimate, Send

TL;DR

• eth_call / eth_estimateGas have callObject constraints.
• eth_estimateGas returns minimum successful gas, not gas_used.
• eth_sendRawTransaction delegates to canister submit API.

Methods

• eth_call -> rpc_eth_call_object
• eth_estimateGas -> rpc_eth_estimate_gas_object
• eth_sendRawTransaction -> rpc_eth_send_raw_transaction

callObject Constraints

• Supported keys: to/from/gas/gasPrice/value/data/nonce/maxFeePerGas/maxPriorityFeePerGas/chainId/type/accessList
• type=0x0 / 0x2 only
• Fee parameter combinations must follow validation rules

Send Operation

• Always monitor receipt status after submit success
