Constructing transactions on NEAR

This repository serves to demonstrate how transactions are created, signed, and sent to the NEAR blockchain. Users are able to send NEAR token to any users with private key.

Prerequisites:

• Current version of Node.js. >=v14.0.0

Install NEAR-CLI

npm i -g near-cli

How to get private key from the seed phrase

near generate-key --seedPhrase 'special style height timber defense leave vote behave elbow scare gallery side'

Setup:

1. Setup an environment variable SENDER_PRIVATE_KEY with the private key of the sender's account.

Either create a .env file in the root of this project, or export a bash variable by running the following in your terminal (replacing the example key).

export SENDER_PRIVATE_KEY=

2. Install dependencies by running:

yarn

Examples:

Send Tokens (High Level)

send-tokens-easy.js will show you the easiest (JavaScript) way to send NEAR tokens (Ⓝ) using a near-api-js method; account.sendMoney()

1. In send-tokens-easy.js, update:

• account IDs for sender and receiver.
• network ID (default is testnet)

2. Run the file and send those tokens!

node send-tokens-easy.js

Send Tokens (Low Level)

send-tokens-deconstructed.js completely dissects the transaction construction process and shows the lowest level way to send NEAR tokens (Ⓝ).

1. In send-tokens-deconstructed.js, update:

• account IDs for sender and receiver.
• network ID (testnet is default)

2. Enter the amount of Ⓝ you would like to send.
3. Run the file and send those tokens!

node send-tokens-deconstructed.js

For a detailed walk-through, see the create-transactions doc.

Happy coding! 🚀
