API AuthenticationClick to view API Authentication details

API calls require authentication with API key via Authorization request header or URL property. Calls are made to one of the Avalanche C Chain Node API endpoints found in your app's dashboard.

For example: https://avalanche--mainnet--rpc.datahub.figment.io

Here's some boilerplate to get you started.

Parameters

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

Response

DATA - the return value of executed contract.

eth_estimateGas

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.

SpecificationView Specification

Parameters

See eth_call parameters, expect that all properties are optional. If no gas limit is specified geth uses the block gas limit from the pending block as an upper bound. As a result the returned estimate might not be enough to executed the call/transaction when the amount of gas is higher than the pending block gas limit.

Response

QUANTITY - the amount of gas used.

Parameters

BLOCKCOUNT - Number of blocks in the requested range. 1 ~ 1024 blocks can be requested in a single query. Less than requested may be returned if not all blocks are available. NEWESTBLOCK - Highest number of blocks in the requested range. REWARDPERCENTILES - (optional) Percentage values between 0 and 100, sampled in ascending order.

Response

OLDESTBLOCK - Smallest 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 gas usage. Which is calculated as the ratio of gasUsed and gasLimit. REWARD - (Optional) An array of effective priority fee per gas data points from a single block. All zeroes are returned if the block is empty.

eth_baseFee

Get the base fee for the next block.

To check if the state has changed, call eth_getFilterChanges. A note on specifying topic filters: Topics are order-dependent. A transaction with a log with topics [A, B] will be matched by the following topic filters:

[] "anything"
[A] "A in first position (and anything after)"
[null, B] "anything in first position AND B in second position (and anything after)"
[A, B] "A in first position AND B in second position (and anything after)"
[[A, B], [A, B]] "(A OR B) in first position AND (A OR B) in second position (and anything after)"
Parameters

SpecificationView Specification

By adding a prefix to the message makes the calculated signature recognizable as an Ethereum specific signature. This prevents misuse where a malicious dapp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim. Note: the address to sign with must be unlocked.

Parameters

DATA, 20 Bytes - address
DATA, N Bytes - message to sign

Response

DATA: Signature

eth_signTransaction

Signs a transaction that can be submitted to the network at a later time using with eth_sendRawTransaction.

Parameters

addresses to get the UTXOs for.
At most limit UTXOs are returned. If limit is omitted or greater than 1024, it is set to 1024.
If startIndex is omitted, will fetch all UTXOs up to limit.
When using pagination (ie when startIndex is provided), UTXOs are not guaranteed to be unique across multiple calls. That is, a UTXO may appear in the result of the first call, and then again in the second call.
encoding sets the format for the returned UTXOs. Can only be hex when a value is provided.

Response

utxos is a list of UTXOs such that each UTXO references at least one address in addresses.
At most limit UTXOs are returned. If limit is omitted or greater than 1024, it is set to 1024.
This method supports pagination. endIndex denotes the last UTXO returned. To get the next set of UTXOs, use the value of endIndex as startIndex in the next call.
If startIndex is omitted, will fetch all UTXOs up to limit.
When using pagination (ie when startIndex is provided), UTXOs are not guaranteed to be unique across multiple calls. That is, a UTXO may appear in the result of the first call, and then again in the second call.
When using pagination, consistency is not guaranteed across multiple calls. That is, the UTXO set of the addresses may have changed between calls.
encoding sets the format for the returned UTXOs. Can only be hex when a value is provided.

avax.import

Finalize the transfer of a non-AVAX or AVAX from X-Chain or P-Chain to the C-Chain. Before this method is called, you must call the X-Chain’s avm.exportor P-Chain’s platform.exportAVAX with assetID AVAX to initiate the transfer.
