From Crypto.org Chain (Cronos Bridge Web App)
Transfer assets from Crypto.org Chain using Cronos Bridge Web App
Introduction
The Cronos bridge’s goal is to support a seamless transfer of assets between blockchains to foster interoperability and for users to enjoy the best Dapps and earnings no matter the chain.
The Cronos Bridge (Beta) can be found at https://cronos.org/bridge
Our bridge is a fully decentralized protocol built on the open-source projects of IBC and Gravity Bridge.
Please read the guide carefully and review the project documentation as misuse may cause incorrect transfer or even loss of assets. We recommend transferring a small amount first to get yourself acquainted with the bridge before moving significant amounts.

- Crypto.org <=> Cronos;
- Cosmos <=> Cronos;
- Terra <=> Cronos;
- Akash <=> Cronos.

We are constantly working on adding new tokens and chain support. If you have any feedback and issues, please drop us an email at product.bridge@crypto.org.
How to use the Cronos Bridge [Web Dapp]
1. Connect your wallet
Click the “Connect Wallet’ button to connect your desktop or browser extension wallet. We currently support browser-compatible versions of the Metamask, Keplr, and Crypto.com DeFi Wallet. Once a connection request is sent, look for a popup from your wallet interface or click into the wallet extension to give consent.
Note 1: If you are bridging assets from or to Crypto.org, you may specify the destination wallet by pasting the address directly or connecting a second wallet to avoid manual errors.
Note 2: Currently, Terra ⇔ Cronos only support Keplr wallet. Learn how to add your Terra station wallet to Keplr wallet, please click here.
2. Select Network and Token
Select the origin chain on the left and the destination chain on the right in the bridge interface. We will do our best to auto-suggest your wallet network to match the desired transfer parameter. However, a manual adjustment on your end may be needed to set your wallet to match the selected network.
If you are transferring from or to Crypto.org, you need to specify the destination address by inputting the address manually or connecting a second wallet to receive your funds.
Once the networks are chosen, select the asset you would like to transfer.
3. Enter the amount
Once the network and asset have been chosen, insert and confirm the amount you would like to transfer.
Our decentralized bridge protocol does not impose a minimum and maximum amount. However, bridging a very small amount may have a high gas fee in proportion to the amount transferred.
After the amount is entered, the bridge network fees will be calculated accordingly. The bridge itself and Crypto.org do not charge an additional fee.
During the promotional launch period, the network fee incurred by the bridge will be waived. You will still be liable to pay a gas fee directly on your preferred wallet charged by the source network.
Before bridging a large amount, we encourage testing a transfer of a minor amount first to ensure all the settings are correct.
4. Confirm the transaction
Once all transfer settings have been confirmed, a transaction confirmation page will pop up summarizing the transaction.
This will send a transaction request to your wallet; please confirm on your wallet screen to ultimately authorize the transfer.
Please note that after bridging the tokens, they will be converted into the destination blockchain-supported tokens. See FAQ for more information
5. Bridging assets
After the transaction is confirmed from the wallet, the bridge operation will commence. First, we will initiate and wait for the deposit of the assets on the origin chain. Once the deposit is confirmed, we will initiate the transfer in the destination chain to your desired receiving wallet address. Both transactions will include an external link to view and monitor the transaction on-chain via scanning utilities such as Cronos, and Crypto.org explorer.
Even if you dismiss, quit, or refresh the page, a small popup reminder will be available to indicate an in-progress transaction. A “transfer completed” message will finally confirm that the transaction has been completed successfully. You may also see a full record of past transactions tied to your wallet in the History tab.
Thank you for using the Cronos bridge and supporting the Crypto.org ecosystem!

FAQ
What are the fees involved?
-The bridge service itself is free and does not charge any additional service fees. The fees displayed are network gas fees which the blockchain infrastructure charges itself to process the transactions and vary depending on the network.
- For any bridge transaction, network gas fees are incurred on two chains: origin and destination.
- For the origin chain gas fee, this will be displayed and settled directly on your wallet extension.
- For the destination chain gas fee (“Bridge network fee”), our decentralized bridge is tasked to collect the appropriate gas fee and pay the network.
How does the Bridge network fee waiver work?
- The following transactions are eligible for a fee waiver:
- Crypto.org => Cronos;
- Cronos => Crypto.org;
- Cosmos => Cronos;
- Terra => Cronos;
- Akash => Cronos.
- The fee waived is the bridge network transaction fee on the destination chain. However, you are still liable to pay for the origin chain gas fee directly on your wallet extension.
- This is a promotional waiver; we reserve the right to modify and terminate the promotion at any time
How fast is the transfer?
- IBC Transfers will generally take around 1 minute to complete.
Can I transfer assets to a different wallet than my own?
- For transfers between Cronos and Crypto.org, we support either connecting a second compatible wallet or inputting the wallet address string.
- If possible, we recommend connecting the second wallet to avoid manual typing and potential malware risks such as clipboard attacks.
What are the support blockchains and tokens?
- The networks supported are:
- Crypto.org;
- Cronos;
- Cosmos;
- Terra;
- Akash;
- Coming Soon: Ethereum
What are the supported wallets?
- The initially supported wallets will be Crypto.com DeFi Wallet, Metamask, and Keplr.
- Please ensure to set the correct active network on your Wallet if it is supported.
Can I complete multiple transfers in one go?
- While it is possible to have multiple ongoing transactions, we recommend having one transaction at a time, even if there is some waiting time to avoid issues and duplication.
Where can I report bugs and provide product feedback?
For any bug reports, or feedback please contact contact.bridge@crypto.org. This is for the web Cronos bridge only. For Crypto.com app, exchange, and DeFi wallet, contact directly https://help.crypto.com/en/
How do I find my missing funds?
- Please check the transaction history table for your past transactions. If your transactions are not on the list, it was likely not initiated at all.
- If you believe you still have missing funds, please contact us at product.bridge@crypto.org.
Is transferring tokens across blockchains safe?
- As with any decentralized application, there is a degree of risk related to code exploits and hacking.
- Our bridge code is publicly available. We leverage open-source code from the IBC protocol and Gravity Bridge projects.
