Fungible Token (FT) Example 👋

This repository contains an example implementation of a fungible token contract in Rust which uses near-contract-standards and workspaces-rs tests.


How to Build Locally?

Install cargo-near and run:

cargo near build

How to Test Locally?

cargo test

How to Deploy?

To deploy manually, install cargo-near and run:

# Create a new account
cargo near create-dev-account

# Deploy the contract on it
cargo near deploy <contract-account-id>

# Initialize the contract
near call <contract-account-id> new '{"owner_id": "<contract-account-id>", "total_supply": "1000000000000000", "metadata": { "spec": "ft-1.0.0", "name": "Example Token Name", "symbol": "EXLT", "decimals": 8 }}' --accountId <contract-account-id>

Basic methods

# View metadata
near view <contract-account-id> ft_metadata

# Make a storage deposit
near call <contract-account-id> storage_deposit '' --accountId <account-id> --amount 0.00125

# View balance
near view <contract-account-id> ft_balance_of '{"account_id": "<account-id>"}'

# Transfer tokens
near call <contract-account-id> ft_transfer '{"receiver_id": "<account-id>", "amount": "19"}' --accountId <contract-account-id> --amount 0.000000000000000000000001

Notes

  • The maximum balance value is limited by U128 (2**128 - 1).
  • JSON calls should pass U128 as a base-10 string. E.g. "100".
  • This does not include escrow functionality, as ft_transfer_call provides a superior approach. An escrow system can, of course, be added as a separate contract or additional functionality within this contract.
