Cronos is an EVM-compatible Layer 1 built on the Cosmos SDK (chain ID 25). Gas is paid in CRO. 1inch supports Classic swaps, Fusion, Fusion+ cross-chain swaps and Limit Orders on Cronos. Liquidity comes from VVS Finance v2/v3 and Ferro.
How-to Guide
1. Add Cronos to your wallet
Most wallets add the network automatically when you connect to the 1inch dApp. To add it manually, use:
Network name: Cronos Mainnet
Chain ID: 25
Currency symbol: CRO
RPC URL: https://evm.cronos.org
Block explorer: https://cronoscan.com
2. Get CRO for gas
Keep a small amount of CRO, about 1 CRO covers several swaps. Classic swaps and approvals pay gas in CRO. Fusion swaps are gasless, the resolver pays the gas. To move funds to Cronos, use a Fusion+ cross-chain swap from another chain or the Cronos Bridge.
3. Open the 1inch dApp and switch to Cronos
Go to https://1inch.com/swap/.
Click the network selector at the top and choose Cronos, or select it in the Connect Wallet → Choose Network window.
Connect your wallet and accept the Terms of Service.
The network indicator switches to Cronos and you can swap.
4. Start swapping
Select the token to swap from and the token to receive, for example CRO to USDC.
Choose the mode: Classic, Fusion (gasless, MEV protected) or Limit Order.
Check the quote and confirm the transaction in your wallet.
What you can trade
CRO, WCRO, USDC and the other listed tokens, plus any token added by contract address. Cronos has few liquidity sources. Check the price impact in the quote before a large swap.
