Autheo JSON-RPC API

As Autheo is built on the Cosmos EVM model, our JSON-RPC API closely mimics that of Ethereum. Developers familiar with Ethereum architecture should find Autheo familiar, and the following API matches those of most EVM compatible Layer-1 blockchains.

This document contains information on the JSON-RPC API endpoints that external applications can use to interact with the Autheo platform.

NOTE: In all examples provided below referencing https://testnet-rpc1.autheo.com, you may also use https://testnet-rpc2.autheo.com.

Note: the address to sign with must be unlocked.

Parameters

DATA, 20 Bytes - address

DATA, N Bytes - message to sign

Returns

DATA: Signature

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.

Parameters

See eth_call parameters, except 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.

Returns

QUANTITY - the amount of gas used.

// Request
curl -X POST https://testnet-rpc1.autheo.com -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "eth_estimateGas", "params": [{"to": "0x89A7EF2F08B1c018D5Cc88836249b84Dd5392905", "data": "0x18160ddd"}, "latest"], "id": 1}'

eth_newFilter

Creates a filter object, based on filter options, to notify when the state changes (logs). 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

Object - The filter options:

fromBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last proposed block, "safe" for the latest safe block, "finalized" for the latest finalized block, or "pending", "earliest" for transactions not yet in a block.

toBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last proposed block, "safe" for the latest safe block, "finalized" for the latest finalized block, or "pending", "earliest" for transactions not yet in a block.

address: DATA|Array, 20 Bytes - (optional) Contract address or a list of addresses from which logs should originate.

topics: [Array] of DATA, - (optional) Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with "or" options.

[Array] - Array of log objects, or an empty array if nothing has changed since last poll.

For filters created with eth_newBlockFilter the return are block hashes (DATA, 32 Bytes), e.g. ["0x3454645634534..."].

For filters created with eth_newPendingTransactionFilter the return are transaction hashes (DATA, 32 Bytes), e.g. ["0x6345343454645..."].

For filters created with eth_newFilter logs are objects with following params:

removed: TAG - true when the log was removed, due to a chain reorganization. false if its a valid log.

logIndex: QUANTITY - integer of the log index position in the block. null when its pending log.

transactionIndex: QUANTITY - integer of the transactions index position log was created from. null when its pending log.

transactionHash: DATA, 32 Bytes - hash of the transactions this log was created from. null when its pending log.

blockHash: DATA, 32 Bytes - hash of the block where this log was in. null when its pending. null when its pending log.

blockNumber: QUANTITY - the block number where this log was in. null when its pending. null when its pending log.

address: DATA, 20 Bytes - address from which this log originated.

data: DATA - contains zero or more 32 Bytes non-indexed arguments of the log.

topics: [Array] of DATA - Array of 0 to 4 32 Bytes DATA of indexed log arguments. (In solidity: The first topic is the hash of the signature of the event (e.g. Deposit(address,bytes32,uint256)), except you declared the event with the anonymous specifier.)

eth_getFilterLogs

Returns an array of all logs matching filter with given id.

Parameters

QUANTITY - The filter id.

params: [

"0x16", // 22

]

Returns

See eth_getFilterChanges

Example

// Request
curl -X POST https://testnet-rpc1.autheo.com -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "eth_getFilterLogs", "params": ["0x44ff3a54d0a2c4c06c4684d596b285e7"], "id": 2}'

Result

See eth_getFilterChanges

eth_getLogs

Returns an array of all logs matching a given filter object.

Parameters

Object - The filter options:

address: DATA|Array, 20 Bytes - (optional) Contract address or a list of addresses from which logs should originate.

topics: Array of DATA, - (optional) Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with "or" options.

blockhash: DATA, 32 Bytes - (optional, future) With the addition of EIP-234, blockHash will be a new filter option which restricts the logs returned to the single block with the 32-byte hash 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.

params: [

{

topics: [

"0x000000000000000000000000a94f5374fce5edbc8e2a8697c15331677e6ebf0b",
