leo query
The leo query command is used to get data from a network supporting the canonical snarkOS endpoints.
Subcommands
block- Query block information.transaction- Query transaction information.program- Query program source code and live mapping values.stateroot- Query the latest stateroot.committee- Query the current committee.mempool- Query transactions and transmissions from the memory pool.peers- Query peer information.
leo query block
To fetch blocks from a given network, run the following command
leo query <ID>
where <ID> is either a specific block height or block hash. The block will be returned in JSON format.
For example, you can fetch the Mainnet genesis block by running either of the following commands:
leo query block 0 --network mainnet --endpoint https://api.explorer.provable.com/v1
leo query block ab1sm6kyqle2ftg4z8gegafqrjy0jwjhzu6fmy73726dgszrtxhxvfqha0eee --network mainnet --endpoint https://api.explorer.provable.com/v1
Flags:
--network <NETWORK>
Specifies the network to deploy to. Overrides any NETWORK environment variable set manually or in a .env file. Valid network names are testnet, mainnet, and canary.
--endpoint <ENDPOINT>
The endpoint to deploy to. Overrides any ENDPOINT environment variable set manually or in a .env file.
--latest
-l
Queries the latest block.
leo query block --latest
--latest-hash
Queries the hash of the latest block.
leo query block --latest-hash
--latest-height
Queries the height of the latest block
leo query block --latest-height
--range <START_HEIGHT> <END_HEIGHT>
-r <START_HEIGHT> <END_HEIGHT>
Queries up to 50 consecutive blocks.
leo query block --range <START_HEIGHT> <END_HEIGHT>
--transactions
-t
Queries all transactions at the specified block height
leo query block <BLOCK_HEIGHT> --transactions
--to-height
Queries the block height corresponding to a hash value
leo query block <BLOCK_HASH> --to-height
leo query transaction
To fetch a specific transaction from a given network, run the following command:
leo query transaction <ID>
where <ID> is the ID of the transaction. The transaction will be returned in JSON format.
Flags:
--network <NETWORK>
Specifies the network to deploy to. Overrides any NETWORK environment variable set manually or in a .env file. Valid network names are testnet, mainnet, and canary.
--endpoint <ENDPOINT>
The endpoint to deploy to. Overrides any ENDPOINT environment variable set manually or in a .env file.
--confirmed
-c
Returns information (including details about onchain execution) about the queried transaction if it was confirmed.
--unconfirmed
-u
Queries the original (unconfirmed) transaction.
--from-io <INPUT_OR_OUTPUT_ID>
Get the ID of the transaction that an input or output ID occurred in.
leo query transaction --from-io <INPUT_OR_OUTPUT_ID>
--from-transition <TRANSITION_ID>
Get the ID of the transaction containing the specified transition.
leo query transaction --from-transition <TRANSITION_ID>
--from-program <PROGRAM_NAME>
Get the ID of the transaction that the specified program was deployed in.
leo query transaction --from-program <PROGRAM_NAME>
leo query program
To fetch a specific program from a given network, run the following command:
leo query program <PROGRAM_NAME>
You can also use this to query specific mappings and mapping values from a given program. For example, if you wanted to query your public balance of Aleo credits:
leo query program credits.aleo --mapping-value account <YOUR_ADDRESS>
Flags:
--network <NETWORK>
Specifies the network to deploy to. Overrides any NETWORK environment variable set manually or in a .env file. Valid network names are testnet, mainnet, and canary.
--endpoint <ENDPOINT>
The endpoint to deploy to. Overrides any ENDPOINT environment variable set manually or in a .env file.
--mappings
Lists all mappings defined in the latest deployed edition of the program.
--mapping-value <MAPPING> <KEY>
Get the value corresponding to the specified mapping and key. Will return null if key is not present in mapping.
--edition <EDITION>
An optional edition to query for when fetching the program source. If not specified, the latest edition will be used.
The edition of the program is set to 0 upon initial deployment and is incremented by 1 each time the program is upgraded. See the Upgrading Programs guide for more details.
leo query stateroot
This command queries the latest stateroot of a given network.
Flags:
--network <NETWORK>
Specifies the network to deploy to. Overrides any NETWORK environment variable set manually or in a .env file. Valid network names are testnet, mainnet, and canary.
