Important Notes
- Token Contracts: Verified contracts will be published via official Cronos channels. Avoid unverified contracts to prevent fund loss.
- Supported Assets Only: Transfers are limited to the assets listed above.
Token Standard: CRC-20
Cronos uses the CRC-20 token standard, ensuring compatibility across its ecosystem. Withdrawals from Crypto.com App/Exchange convert assets into wrapped CRC-20 tokens (1:1 ratio).
Example: Withdrawing USDC from Crypto.com App delivers it as CRC-20 USDC on Cronos.
Bridging CRO from Crypto.org Chain
The decentralized Cronos Bridge leverages:
- Inter-Blockchain Communication (IBC)
- Gravity Bridge module
CRO is routed via IBC, then wrapped into native CRO on Cronos’ EVM.
