World Chain
What is World Chain and why do I have to migrate to it?
What is the World Chain Network?
World Chain is a new blockchain designed for humans, built to scale the World protocol and the broader Ethereum community to 1 billion people and beyond.
Migrating to World Chain will result in these benefits:
- Free transfers in World App for verified users
- Transactions will be completed at twice the speed of those on the Optimism network, ensuring faster and more efficient processing
World Chain is designed first and foremost to significantly increase capacity so new people can continue to join at scale, and existing users can enjoy faster, cheaper, and more reliable transactions.
How do I migrate World App assets to World Chain?
From October 2024, World App transactions will be taking place in the World Chain Network.
All World App users will need to migrate their existing app assets (tokens) from the Optimism Network into the World Chain Network. World App will prompt you to begin the migration process once it is ready.
To migrate to World Chain:
- Tap on Start migration
- The migration process will begin and should be done in minutes. Once it completes, you will see a confirmation screen, which will allow you to continue using the app as normal.
What will happen to transactions sent to me via the Optimism Network?
If you have already migrated to World Chain and someone sends you a transaction via the Optimism Network, World App will show you the following screen so you can migrate those assets to your wallet:
Simply tap the Understand button to get the migration started. Your assets will appear in the wallet shortly.
To avoid losing funds, please make sure future transactions are done on the World Chain Network.

How do I find a transaction on the World Chain Network?
If you need to locate a specific transaction on the World Chain network, you can do so by using a blockchain explorer such as the World Chain Explorer. Follow the instructions below to find your transaction.
Steps to Find a Transaction Using World App
If you used World App to make a transaction, you can easily locate its blockchain record by following these steps:
1. Go to the Wallet tab and tap on the Clock icon on the upper corner of the screen.
2. Select the specific transaction and then tap on Show More
3. You'll be able to view all the relevant information regarding the transaction and have the option to view the Details of transaction on the blockchain through the World Chain Explorer.
Note: Transaction ID and Transaction Hash are both different. For more information on what a Transaction ID is, please check our detailed guide here.
Steps to Find a Transaction Directly in the World Chain Explorer
1. Get the Transaction Hash (TxID) or Wallet Address
When you perform any transaction on the World Chain network, you’ll receive a unique transaction hash. You can usually find this in your wallet or the app where the transaction was made.
If you do not have the transaction hash, you can also use the sender’s or receiver’s wallet address.
2. Open World Chain Explorer
Go to the official World Chain Explorer which can be found through the following link: https://worldscan.org/
3. Enter the Transaction Hash or Wallet Address
Once on the explorer page, you'll see a search bar. Enter the transaction hash (TxID) or wallet addressinto the search bar and press Enter or tap on the magnifying glass to start the search.
4. Review the Transaction Details
The explorer will display detailed information about the transaction, including:
- Status
- Transaction value (Amount of tokens involved)
- Fees
- Timestamp of the transaction
- Sender and receiver wallet addresses
Example of a transaction record found in the blockchain explorer
Troubleshooting
Transaction Not Found
If the transaction doesn’t appear, double-check the transaction hash or address to ensure it is correct. It can sometimes take a few moments for new transactions to appear on the blockchain.
Pending Transactions
If your transaction is still pending, it may take time depending on network congestion. You can monitor its progress in the same explorer.
Transaction Shows Completed but Funds Have Not Been Received
Transactions marked as completed in World App and/or on the blockchain may take some time to appear in the destination wallet or address. Please allow up to 48 hours and check again. If the funds have not arrived after this period, contact the destination wallet or centralized exchange’s support team for further assistance.

Why are crypto transactions irreversible?
Crypto transactions are permanent and cannot be reversed once they’re confirmed. This is a key feature of blockchain technology, which powers most cryptocurrencies.
This means that once funds are sent, they cannot be recovered unless the recipient chooses to send them back.
1. Blockchain is Unchangeable
Once a transaction is recorded on the blockchain (a public digital ledger), it cannot be changed or deleted. This is called immutability. It helps keep the network secure and prevents anyone from tampering with past transactions.
2. No Central Authority
Unlike banks, cryptocurrencies operate on decentralized networks with no single authority controlling the system. This means there is no bank or company that can reverse a transaction once it’s been processed.
3. Transactions are Final
When a crypto transaction is confirmed, it’s final. There are no chargebacks or cancellations like with credit card payments. Because transactions cannot be undone, it’s important to carefully review all details before sending funds.
4. Transaction Validation
Each transaction goes through a validation process. Once it’s confirmed by the network, it is permanently added to the blockchain.
5. Sufficient Balance is Required
A crypto transaction can only be processed if you have enough balance in your wallet to cover:
The amount you are sending
Any applicable network fees
If your balance is insufficient, the transaction will not go through.
How to Protect Yourself?
- Double-check the wallet address before sending funds.
- Confirm that you are using the correct blockchain network (chain). Sending funds to the correct address on the wrong network may result in permanent loss.
- Make sure the token you are sending is supported by the receiving wallet.
- Verify the amount before confirming the transaction.
- Only send funds to trusted recipients and be careful of scams.
