Native CRO is the native currency of the Crypto.org Chain, which enables near-instant CRO transactions with minimal fees. ERC20 CRO tokens are created and hosted on the Ethereum blockchain, where ETH network fees are required to carry out crypto transactions.

Crypto.org Chain is a public, open-source and permissionless blockchain - a fully decentralized network with high speed and low fees, designed to be a public good that helps drive mass adoption of blockchain technology through use cases like Payments, DeFi and NFTs.

Crypto.org Chain has the following key-value propositions:

Native CRO and ERC20 CRO are different crypto assets, although sharing the same token name, symbol and fiat value (1 native CRO = 1 ERC20 CRO), please ensure you understand the differences and confirm with your recipient or receiving wallet when you’re transacting CRO.

How do I receive native or ERC20 CRO to DeFi Wallet?

  4. You will see 2 tabs - “CRO” and “ERC20”, choose the corresponding chain tab based on your use case of CRO on DeFi Wallet

Why is there no memo for the Crypto.com DeFi Wallet native CRO receive address?

Crypto.com DeFi Wallet is a decentralized (non-custodial) wallet where you’re the one and only custody of your wallet and crypto assets. Your native CRO address is unique to you and isn't shared with other wallet users, that’s why there isn’t a memo in addition to your native CRO address to identify your wallet.

When is a memo required for sending native CRO?

Follow the checklist below to decide whether a memo is required for your recipient

  1. Ask your recipient whether there is a memo for the native CRO address.

  2. Is the receiving address generated by a centralized or decentralized wallet? (The recipient will own the recovery phrase if it’s a decentralized wallet, in which case a memo is not required)

  3. If you are still unsure, we strongly advise you to send a small test amount first to ensure your recipient is able to receive the crypto.

We will not be able to locate/reverse the funds if you fail to include the memo when sending native CRO to a centralized wallet.

How can I convert my ERC20 to native CRO via DeFi Wallet?

To convert your ERC20 CRO to native CRO on the DeFi Wallet, please follow the instructions of the in-app CRO Migration Tool. Please note that you can’t convert native CRO back to ERC20 CRO via the CRO Migration Tool, so please consider your use cases carefully before the migration -

  • Native CRO is required for Crypto.org Chain Staking via DeFi Earn

  • ERC20 CRO is required to perform swap on Ethereum Network

If by any chance you need to convert native CRO back to ERC20 CRO, a workaround will be to deposit your native CRO to our centralized platforms - Crypto.com App or Exchange and choose to withdraw CRO as ERC20 tokens.
