Testnet: PDEX Migration Tutorial

This post was originally published on Polkadex

The next phase of the Polkadex Testnet includes the PDEX Migration process redesigned for Test Tokens

Here’s a detailed guide on how to migrate your Polkadex Test Tokens from Ethereum to Polkadex on the Polkadex Testnet

Step 1 — Accessing Ropsten and getting Test ETH from a Ropsten token faucet

You will first need to access the Ropsten Test Network of Ethereum. You can select it in the drop-down list on your Metamask browser extension as seen below.

Step 2 — Claim ERC-20 Polkadex Test Tokens

1. Once you have ETH in your Ropsten Test Network wallet, you will need to claim ERC-20 Polkadex Test Tokens.

Step 3 —Migrate from Ethereum to Polkadex

Once you have some ETH and some Polkadex Test Tokens on the Ropsten Test Network and you have your Polkadot.js browser extension wallet set up (along with Metamask), you are ready to migrate!

Migrated!

Once the migration is done, you’ll see it reflected on the Test Token balances of your Polkadex Testnet wallet and the Ethereum Ropsten Test Network. You can even visit the Polkadex Testnet app on Polkadot.js/apps to check your account’s Test Token balance. Keep in mind your account needs to retain a balance of over 1 Test Token to stay above the existential deposit and remain active.

Keep in mind

The migration protocol is currently only designed to migrate 1 Test Token at a time. This is intended to maximize the amount of times the migration process is triggered in order to stress-test the migration protocol. On mainnet, there will not be a cap on the amount of PDEX migrate-able in one transaction.

The importance of testing

While this guide is specific to the migration of Test Tokens from Ethereum’s Ropsten Test Network to the Polkadex Testnet, the process is designed to be as similar to the PDEX migration from Ethereum to the Polkadex Mainnet. It is important to test the migration protocol thoroughly before it is pushed out onto the Mainnet, where real PDEX are at stake.
