Eth

These methods are used for Ethereum-compatible JSON-RPC calls. For in-depth information on each of these methods, take a look at the official Ethereum API documentation.
EthAccounts
This method is intended to return a list of addresses owned by client. However, eth_accounts will always return and empty array [] since Filecoin does not manage Ethereum private keys.
Permissions: read
Inputs: none
Example:
curl --location --request POST 'https://api.node.glif.io' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc":"2.0",
    "method":"eth_accounts",
    "params":[],
    "id":1
}' | jq
{
  "jsonrpc": "2.0",
  "result": [],
  "id": 1
}
EthBlockNumber
Returns the number of most recent block.
Permissions: read
Inputs: none
Example:
curl --location --request POST 'https://api.node.glif.io' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc":"2.0",
    "method":"eth_blockNumber",

}' | jq
{
  "jsonrpc": "2.0",

  "id": 1
}
EthCall
Executes a new message call immediately without creating a transaction on the blockchain.
This documentation section is a work-in-progress.
Permissions: read
Input:
1.Object - The transaction call object:
from: DATA, 20 Bytes - (optional) The address the transaction is sent from.
to: DATA, 20 Bytes - The address the transaction is directed to.
gas: QUANTITY - (optional) Integer of the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.
gasPrice: QUANTITY - (optional) Integer of the gasPrice used for each paid gas
value: QUANTITY - (optional) Integer of the value sent with this transaction
data: DATA - (optional) Hash of the method signature and encoded parameters. For details see Ethereum Contract ABI in the Solidity documentation​
2.QUANTITY|TAG - integer block number, or the string "latest", "earliest" or "pending". See the default block parameter.
Inputs:

EthEstimateGas
Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. The transaction will not be added to the blockchain. Note that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.
This documentation section is a work-in-progress.

EthFeeHistory
Returns a collection of historical gas information.
Permissions: read
Inputs:
BLOCKCOUNT - Number of blocks in the requested range. Between 1 and 1024 blocks can be requested in a single query. Less than requested may be returned if not all blocks are available.
NEWESTBLOCK - Highest number block of the requested range.
REWARDPERCENTILES - (optional) A monotonically increasing list of percentile values to sample from each block’s effective priority fees per gas in ascending order, weighted by gas used.
Returns:
object:
OLDESTBLOCK - Lowest number block of the returned range.
BASEFEEPERGAS - An array of block base fees per gas. This includes the next block after the newest of the returned range, because this value can be derived from the newest block. Zeroes are returned for pre-EIP-1559 blocks.
GASUSEDRATIO - An array of block gas used ratios. These are calculated as the ratio of gasUsed and gasLimit.
REWARD - (Optional) An array of effective priority fees per gas data points from a single block. All zeroes are returned if the block is empty.

Permissions: read
Input:
1.String - 20 Bytes - Address.
2.String - Either the hex value of a block number OR One of the following block tags:
pending: a sample next block built by the client on top of latest and containing the set of transactions usually taken from local mempool. Intuitively, you can think of these as blocks that have not been mined yet.
latest: the most recent block in the canonical chain observed by the client, this block may be reorganized out of the canonical chain even under healthy/normal conditions.
safe: the most recent crypto-economically secure block, cannot be reorganized outside of manual intervention driven by community coordination. Intuitively, this block is “unlikely” to be reorganized.
finalized: the most recent crypto-economically secure block, that has been accepted by >2/3 of validators. Cannot be reorganized outside of manual intervention driven by community coordination. Intuitively, this block is very unlikely to be reorganized.
earliest - The lowest numbered block the client has available. Intuitively, you can think of this as the first block created.

EthMaxPriorityFeePerGas
Returns a fee per gas that is an estimate of how much you can pay as a priority fee, or ’tip’, to get a transaction included in the current block. Generally you will use the value returned from this method to set the maxFeePerGas in a subsequent transaction that you are submitting.

EthNewBlockFilter
Installs a persistent filter to notify when a new block arrives.
Permissions: write
Inputs: none
curl --location --request POST 'https://api.node.glif.io' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc":"2.0",
    "method":"eth_newBlockFilter",

  "id": 1
}
EthNewFilter
Creates a filter object, based on filter options, to notify when the state changes (logs). Unlike eth_newBlockFilter which notifies you of all new blocks, you can pass in filter options to track new logs matching the topics specified. To check if the state has changed, call eth_getFilterChanges.
Permissions: write
Inputs:
array:
object:
string: BlockHash. Using blockHash is equivalent to fromBlock = toBlock = the block number with hash blockHash. If blockHash is present in the filter criteria, then neither fromBlock nor toBlock are allowed.
array:
string: Contract address or a list of addresses from which logs should originate.
string: Either the hex value of a block number OR one of the following block tags:
pending: A sample next block built by the client on top of latest and containing the set of transactions usually taken from local mempool. Intuitively, you can think of these as blocks that have not been mined yet.
latest: The most recent block in the canonical chain observed by the client, this block may be reorganized out of the canonical chain even under healthy/normal conditions.
safe: The most recent crypto-economically secure block, cannot be reorganized outside of manual intervention driven by community coordination. Intuitively, this block is “unlikely” to be reorganized.
finalized: The most recent crypto-economically secure block, that has been accepted by >2/3 of validators. Cannot be reorganized outside of manual intervention driven by community coordination. Intuitively, this block is very unlikely to be reorganized.
earliest: The lowest numbered block the client has available. Intuitively, you can think of this as the first block created.
