To ensure that your transaction doesn't remain in "pending" status for too long, you should include enough to cover the fees:
Minimum gas fee: 2,500 gwei.
Minimum priority fee: 1 gwei.
Yes, the Chiliz Chain is EVM compatible and supports Solidity. Note that CHZ on Chiliz Chain is the native token and not a smart contract. This is similar to ETH on Ethereum.
Use Solidity 0.8.23 for your contracts. Chiliz Chain does not support higher versions currently. Ensure we are running with EVM version 19.
You can get test tokens for the Spicy network through faucets.
Check our dedicated documentation here:
You can create your own fan tokens, which are ERC20 tokens with 0 decimals.
While we encourage using existing ones, deploying your own on the Spicy Testnet may provide more liquidity for testing.
CREATE2 is support on Chiliz Chain Mainnet.
The Chiliz token (CHZ) has 18 decimal places.
Refer to the following page for more details:
If you run your own node, we advise you to upgrade both mainnet and testnet nodes whenever a newer version is available.
Testnet is a replica of the Mainnet blockchain and is used to test out the chain for free, without consuming gas fees. Mainnet on the contrary is where all the real transactions happen and you will be charged the actual gas fees as well. It's a real transfer of crypto coins / Fan tokens.
The Testnet is a testing ground for smart contracts that will later be deployed on Chiliz Chain. We are offering the Testnet for users to get a chance to play around with and test some basic on-chain smart contracts.
Spicy is our Testnet blockchain and Chiliz Chain is our Mainnet blockchain.
We launched the Scoville Testnet in early 2022 to enable users to test out dApps that will be later deployed on the Chiliz Chain Mainnet.
Following external audits, we decided to improve the overall security and performance of our blockchain. However, since it couldn’t be done without a hard fork, in January 2023 we introduced the Spicy Testnet.
The Scoville Testnet should not be used anymore, and is deprecated.
We encourage all developers to deploy their tests on Spicy Testnet as it will be kept up-to-date to directly reflect the new Chiliz Chain.
Yes, you can wrap on the Spicy Testnet.
You can use our wCHZ token if you prefer an ERC20 version of the token instead of the native token.
ThirdWeb has deployed a CREATE2 factory on the Spicy testnet. For reference, see the unverified contract at .
Currently, there is no direct method to verify contracts on Spicy using Hardhat. We recommend flattening your contracts and using the or . Ensure you correctly set the compiler version, EVM version, and optimization settings during verification.
For reference, see the Wrapped CHZ contract: .
For easier management, consider using services like and for on-chain data instead of running your own node.
Yes! Chiliz support on Biconomy can be verified .
Make sure you are connected to the Spicy Testnet in your wallet (e.g., MetaMask) before connecting, then open the and connect your wallet.
