Introduction

Token standard is essential for the Internet Computer ecosystem, especially for the decentralized finance(DeFi) system, this repository contains code of several token canister templates, developers can choose whichever implementation to issue their own tokens.

Token templates:

motoko: token canister templates implemented in Motoko:

• simple-erc20: Simple ERC20 style token canister implemented in motoko
• erc20-simple-storage: ERC20 style token canister implemented in motoko, support history transaction storage
• erc20: Improved ERC20 style token canister template implemented in motoko, support history transaction storage in a seperate storage canister

rust: token canister templates implemented in Rust:

• erc20: Rust implementation of ERC20 style token canister template
• notify: Rust implementation of notify scheme token canister template

Development

You need the latest DFINITY Canister SDK to be able to build and deploy a token canister:

sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"

Navigate to a token sub directory and start a local development network:

cd erc20
dfx start --background

Create canisters:

dfx canister create --all

Install code for token canister:

dfx build

dfx canister install token --argument="(\"<NAME>\", \"<SYMBOL>\", <DECIMALS>, <TOTAL_SUPPLY>, <YOUR_PRINCIPAL_ID>)"
e.g.:
dfx canister install token --argument="(\"DFinance Coin\", \"DFC\", 8, 10000000000000000, principal \"4qehi-lqyo6-afz4c-hwqwo-lubfi-4evgk-5vrn5-rldx2-lheha-xs7a4-gae\")"

Refer to demo.sh in the corresponding sub directory for more details.
