Algorand Tools

A set of useful apps and snippets to handle Algorand transactions. The package can be used as a library for other applications or as a standalone set of utilities.

Installation

To install the library, use the following command:

$ npm install algorand-tools

Usage

As a library

Import the library in your application by adding the following command:

const algotools = require('algorand-tools');

Applications

build.js

Creates Algorand unsigned transaction.

$ node apps/build.js parameters [options]

Parameters:

• --output {FILENAME} : Transaction file to create.
• --from {ADDRESS} : Sender address.
• --to {ADDRESS} : Receiver address.
• --amount {NUMBER} : Amount to send in microalgos.
• --fee {NUMBER} : Fees to pay (the value is multiplied by the transaction size unless --fixed-fee is specified).
• --first-round [+]{NUMBER} : First round where the transaction should be sent. Use +NUMBER to calculate the round based on the network's current round.

Options:

• --note {BASE64-STRING} : Note to add.
• --last-round last-round [+]{NUMBER} : Last round where the transaction should be sent. Defaults to 1000 after first round. Use +NUMBER to calculate the round based on the network's current round.
• --close {ADDRESS} : Close address. Remaining account funds will be transferred to this address.
• --genesis-hash {BASE64-STRING} : Network's genesis hash. Retrieved from network if not specified.
• --genesis-id {STRING} : Network's genesis ID. Retrieved from network if not stated.
• --multisig-threshold {NUMBER} : Required signatures for a multsig account template.
• --multisig-addresses {ADDRESS[,ADDRESS...]} : A comma separated list of addresses that make up the multisig account template.
• --fixed-fee : Sets the fee as a fixed value (does not multiply fee by the size of the transaction).
• --node-url http://address:port : Node's url if an access to the network is required. If not specified the ALGOTOOLS_NODE_URL environment variable is used.
• --node-api-token {TOKEN} : Node's api token if an access to network is required. If not specified the ALGOTOOLS_NODE_API_TOKEN environment variable is used.

sign.js

Signs a set of transactions.

$ node apps/sign.js parameters [options]

Parameters:

• --input {FILENAME} or {FOLDERNAME} : Folder and/or file with transactions to sign. Wildcards accepted on filename..
• --output {FILENAME} : Output file to create with signed transactions. Can be used only if input is only one file.

Options:

• --mnemonic "{MNEMONIC}" : Signer's mnemonic. Enclose the 25-word passphrase in quotes. If not provided, the app will ask for it.
• --multisig-threshold {NUMBER} : Required signatures for a multsig account.
• --multisig-addresses {ADDRESS[,ADDRESS...]} : A comma separated list of addresses that make up the multisig account. Required only for the first signature.
• --remove-existing : Remove any previously existing signature from the transaction.

dump.js

Show details about transactions stored in a file.

$ node apps/dump.js parameters

Parameters:

• --input {FILENAME} : File with transactions to show.
• --from {NUMBER} : First transaction index. Starts at 1.
• --to {NUMBER} : Last transaction index.
• --index {NUMBER} : Dumps a single transaction located at the specified index.

generate_address.js

Generates standard or multisig accounts.

$ node apps/generate_address.js single-account-parameters

$ node apps/generate_address.js --multisig multisig-account-parameters

Single account parameters:

• --count {NUMBER} : Number of addresses to generate.

Multisig account parameters:

• --size {NUMBER} : Amount of addresses envolved in the multisig account.
• --req {NUMBER} : Required amount signatures to validate a multisig transaction.

merge.js

Merges transactions of one or more files and, optionally, combines signatures.

$ node apps/merge.js parameters

Parameters:

• --source {FILENAME} or {FOLDERNAME} : Folder and/or file with transactions to merge. Wildcards accepted on filename.
• --output {FILENAME} : File to store the merged transactions.
• --merge-signatures : Merge signatures if two or more transactions matches. If this flag is not set, transactions are just concatenated.

raw_signer.js

Signs raw data or file or verifies if the signature is correct.

$ node apps/raw_signer.js sign-parameters

$ node apps/raw_signer.js --verify verify-parameters

Sign parameters:

• --data {TEXT} : Sign the passed data. Cannot be used with '--filename'.
• --filename {FILENAME} : File to sign. Cannot be used with '--data'.
• --output {FILENAME} : Signature file to generate.
• --mnemonic "{MNEMONIC}" : Signer's mnemonic. Enclose the 25-word passphrase in quotes.

Verify parameters:

• --data {TEXT} : Verify the passed data. Cannot be used with '--filename'.
• --filename {FILENAME} : File to verify. Cannot be used with '--data'.
• --signature {FILENAME} : Signature file to validate.
• --address {ADDRESS} : Address of signer.

send.js

Sends a set of transactions to the network.

$ node apps/send.js parameters

Parameters

• --input {FILENAME} : File with transactions to send.
• --wait : Wait for the network's current round to match transactions' first round if required.
