Tutorial: How to Pay Gas Fees with $ERA and Enjoy Discounts? @Caldera Official #caldera $ERA

The native token of the Caldera ecosystem, $ERA, can not only be used for governance and staking but also to directly pay gas fees and enjoy exclusive discounts. Here is a detailed guide:

1. Preparation

• Acquire ERA: Purchase ERA through exchanges like Binance or participate in Caldera ecosystem airdrops and liquidity mining to obtain tokens.

• Connect Wallet: In a wallet that supports the Caldera Rollup chain (such as MetaMask), switch the network to the target Rollup chain (such as ApeChain or Manta Pacific).

2. Pay Gas Fees

• Select ERA for Payment: When initiating a transaction in a DApp (such as inEVM or RARI Chain), the wallet will prompt you to select the gas token. Check “Use ERA for Payment,” and the system will automatically convert the fee at the real-time exchange rate.

• Discount Mechanism: Some ecosystem projects (such as Ozean) offer a 5%-10% discount on gas fees when paid with $ERA; be sure to confirm the activity rules before the transaction.

3. Cross-Chain Benefits

When cross-chaining via the Metalayer protocol, using $ERA for payment can reduce fees:

• Select $ERA as the fuel token in the cross-chain interface to avoid additional costs associated with ETH conversion.

• Some chains (such as zkXPLA) provide priority packaging services for $ERA users, reducing transaction delays.

Notes

• Ensure that your wallet retains a small amount of $ERA for the initial gas payment; some chains require initial ETH activation.

• Pay attention to official announcements; limited-time events may offer higher discounts (such as fee waivers during developer testing periods).

By following these steps, users can efficiently utilize $ERA to lower on-chain costs while participating in ecosystem development.
