🔧 Supported APIs for In-Memory Node 🔧

⚠️ WORK IN PROGRESS: This list is non-comprehensive and being updated. If there is an API that requires additional support, please start by creating a GitHub Issue.

Key

The status options are:

  • SUPPORTED - Basic support is complete
  • PARTIALLY - Partial support and a description including more specific details
  • NOT IMPLEMENTED - Currently not supported/implemented

DEBUG NAMESPACE

debug_traceCall

source

The debug_traceCall is similar to eth_call but returns call traces for each call.

Currently calls can only be traced on the latest block. This is the default and hence the block argument can be omitted.

The third argument mirrors the TraceConfig of go-ethereum, but with the restriction that the only supported tracer is CallTracer. Memory, Stack and Storage traces are not supported.

Arguments

  • transaction: Transaction

  • block: BlockNumber

  • tracer: TracerConfig

Status

SUPPORTED

Example

curl --request POST \
  --url http://localhost:8011/ \
  --header 'content-type: application/json' \

debug_traceTransaction

source

Returns call traces for the transaction with given hash.

Currently only transactions executed on the dev node itself (ie, not from upstream when using fork mode) can be traced.

hardhat_mine

source

Sometimes you may want to advance the latest block number of the network by a large number of blocks. One way to do this would be to call the evm_mine RPC method multiple times, but this is too slow if you want to mine thousands of blocks. The hardhat_mine method can mine any number of blocks at once, in constant time. (It exhibits the same performance no matter how many blocks are mined.)

Arguments

  • num_blocks: U64 - The number of blocks to mine. (Optional: defaults to 1)
  • interval: U646 - The interval between the timestamps of each block, in seconds. (Optional: defaults to 1)

Example

curl --request POST \
  --url http://localhost:8011/ \
  --header 'content-type: application/json' \
  --data '{
    "jsonrpc": "2.0",
    "id": "2",
    "method": "hardhat_mine",
    "params": [
        "0xaa",
        "0x100"
    ]
}'

hardhat_impersonateAccount

  --url http://localhost:8011/ \
  --header 'content-type: application/json' \

    "params": [
        "0x364d6D0333432C3Ac016Ca832fb8594A8cE43Ca6"
    ]
}'

hardhat_stopImpersonatingAccount

source

Stop impersonating account, should be used after calling hardhat_impersonateAccount. Since we only impersonate one account at a time, the address argument is ignored and the current impersonated account (if any) is cleared.

Arguments

  • address: Address - (Optional) Argument accepted for compatibility and will be ignored

Example

curl --request POST \
  --url http://localhost:8011/ \
  --header 'content-type: application/json' \
