ETHGlobal Tokyo Developer Package

ETHGlobal Tokyo hackers can use MultiBaas for free to build DApps faster and win more prizes.

Congratulations on embarking upon your ETHGlobal journey. This document describes the tools we have available for you to build your application faster using MultiBaas.

The MultiBaas blockchain application server is middleware for the blockchain. You can use it to more easily build decentralized applications (DApps) on one or more blockchain platforms using a REST API, wallet automation, and event queries. To learn more, see What is MultiBaas?

ETHGlobal Plan

For ETHGlobal, we have created a FREE plan type with all the premium features, bells, and whistles available for you to maximise your hackathon time. Go to, create an account, and select the ETHGlobal deployment type on your network of choice.

You will be able to create up to two deployments so, for example, you can use one for testing on the EVM Curvegrid Test Network (faucet included) and one for production on Mainnet.

There are two main approaches to using MultiBaas: 1) creating a new smart contract and 2) accessing an existing smart contract that has already been deployed. You may also need or want to do a combination of both.

Accessing an existing smart contract can help you quickly build an interface into one of the many lucrative As a bonus you will be eligible for our modest prize as well!

Creating a new smart contract

There are a number of ways you can add a smart contract to your MultiBaas deployment, however if you are building and iterating on your contract, we recommend using the

Accessing an existing smart contract

You can also link an existing smart contract that is already deployed on the blockchain. Before linking you will need to add the contract as described above.
