DIP20: A fungible token standard for the DFINITY Internet Computer.

Introduction

Token standard is essential for the Internet Computer ecosystem, especially for the decentralized finance(DeFi) system. We implemented an ERC-20 style token standard in both Motoko and Rust, the standard is named DIP20.

You can find the interface descriptions in the specification file.

This branch contains code of several other token canister templates.

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 the sub directory and start a local development network:

cd motoko
dfx start --background

Create canisters:

dfx canister create --all

Install code for token canister:

dfx build

dfx canister install token --argument="(\"<LOGO>\", \"<NAME>\", \"<SYMBOL>\", <DECIMALS>, <TOTAL_SUPPLY>, <YOUR_PRINCIPAL_ID>, <FEE>)"

e.g.:

dfx canister install token --argument="(\"data:image/jpeg;base64,...\", \"DFinance Coin\", \"DFC\", 8, 10000000000000000, principal \"4qehi-lqyo6-afz4c-hwqwo-lubfi-4evgk-5vrn5-rldx2-lheha-xs7a4-gae\", 10000)"

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

Contributing

We'd like to collaborate with the community to provide better token standard implementation for the developers on the IC, if you have some ideas you'd like to discuss, submit an issue, if you want to improve the code or you made a different implementation, make a pull request!
