Reflection once boomed in 2021, and since then new tokens have appeared that use the reflection concept, an example of a famous reflection token is SafeMoon. In a nutshell “Token Reflection” is a token that charges a tax on each transaction, or rewards token holders and collects a portion of the fee to be put into the liquidity pool.
Many investors like reflection tokens, this is because reflection tokens will provide a passive source of income. Every buying and selling swap transaction on reflection tokens will be deducted (which is often called tax), and the tax tokens will be sent to a specific wallet, or to a liquidity pool, or sent to holders. The amount of tax on each token is different and the tax mechanism also varies, depending on the developer who created the token.
The transaction tax deduction process is called reflection, the process is done automatically in smart contract tokens, it may look complicated, but it is easier than mining coins, staking or farming. Token reflection encourages investors to buy more tokens, because each swap-token will be taxed, which means the supply of tokens in circulation will decrease. The more transactions, the less supply of tokens in the market and this will trigger an increase in token prices. Over a long period of time, tokens will become very scarce (this is called the concept of deflation).
In this article we will provide a tutorial or education to create a crc20 reflection token on the coinex smart chain blockchain, why did we choose coinex? Because coinex smart chain is a blockchain that supports EVM, high performance, very fast transactions and very low transaction fees.
What is Needed to Create a CRC20 Reflection Token?
1# Wallet EVM
There are many evm wallets that you can use, but here I suggest you use the metamask wallet, because it is easier and safer. Metamask supports several versions, such as android, ios, browser versions, use the browser version to make it easier. To use the coinex smart chain blockchain, you must change the metamask rpc wallet to rpc coinex smart chain.
RPC URL : https://rpc.coinex.net
Network Name : Coinex Smart Chain
ChainID : 52
Symbol : CET
Block Explorer : https://www.coinex.net
2# Coin CET (Coin Native Coinex Smart Chain)
Coin CET is the native coin of the coinex smart chain blockchain, the coin is used to pay for all transactions such as sending coins/tokens/nft or for interacting contracts. CET is almost the same as ETH on the ethereum blockchain, used as the main coin on the blockchain. To get CET coins you can buy on Coinex Exchange
Currently the coin cet is worth $0.04x, the price is still very cheap, very suitable for long-term investment, because native-blockchain coins have the potential to increase by thousands of percent such as Matic, bnb, cardano, etc.

How to Create CRC20 Reflection Token ?
1# Deploy Smart Contract
To create a reflection token, we need to deploy a smart contract to the coinex smart chain blockchain, for the deployment process you can use the remixIDE service.
RemixIDE is used to compile and deploy smart contracts, you can use the service to deploy smart contracts or other dapps on the coinex smart chain blockchain.
- Go to remixIDE remix.ethereum.org
- Create a new file with the extension .sol and paste the smart contract in the file
- Compile smart contracts with the appropriate compiler
- Deploy a smart contract, and confirm it in the metamask wallet, wait 2-3 seconds for the transaction to be fully validated.
There are several things you need to set
- _NAME : Name for your token
- _SYMBOL : Symbol for your token
- _DECIMALS : Decimal for your token, yaou can setting range 1 – 18
- _SUPPLY : Total suppy your token
- _TXFEE : Percentage of tax fee for every BUY transaction, this token fee will go to the liquidity pool
- _BURNFEE : The percentage of tokens burned for each BUY transaction
- _CHARITYFEE : The percentage of tokens that will be sent to the charity wallet
- _FEEADDRESS : Address to accommodate charity tokens
- _TOKENOWNER : Owner address
2# Smart Contract Verification
This smart contract is used to create crc20 reflection tokens, almost the same as smart contracts from openzepplin, only different in the feature for automatic reflection (tax collection) when making transactions
3# Listing Tokens to DEX
This reflection token works when a trade swap occurs on the dex exchange, does not apply to the central exchange. You need to list the token to the dex exchange so that the reflection function works perfectly, there are many dex that you can use.
Dex exchange is the right choice for token listing, because it is decentralized and free, there is no need to pay a listing fee. All transactions on the dex exchange are carried out on-chain on the blockchain, without intermediaries, very safe and convenient.
How to List Token to Dex Exchange
- Choose the Dex Exchange that you will use, in this article we use ifswap: ifswap.finance
- Click the “trade” menu, select “liquidity“
- Click “add liquidity“
- The top column, click “select a currency“, you can use the pair usdt/busd/eth/btc/cet
- Bottom column, click “select a currency“, input smart contract token reflection in the search field, click “import“
- Click “i undestand” and click “import“
- Enter the comparison amount for the token price, this will determine the price of each token
- Example comparison (for token prices) = if you enter 10,000 USDT and 10,000,000 tokens, then the price for each token is (10,000 : 10,000,000 = $0.001 USDT). the more USDT/TOKEN liquidity is entered, the better,
4# Exclude Account (DEX Address)
ExcludeAccount is a function in the token smart contract that functions to exclude fees at certain addresses, you need to exclude fees at the DEX Exchange address, so that tokens can be traded (buy-sell), if this is not done, then the token cannot be executed SELL .
this is an example of an ifswap address that we need to “Exclude Account”
UniswapV2Factory: 0x44b7864D360BFf7879402E3B860aF47e6e371208
UniswapV2Router02: 0xBdC129f61d8840ede28EB6e26760682D9c5c30fD
5# Test Token Reflection
To test token reflection, you need to test the swap transaction on the dex exchange, when the swap transaction (buy) is complete, the number of tokens will be reduced according to the percentage of the tax fee that we previously set
in this token *that we created, using some fees (fee in swap-buy)
- tax fee : token will go to liquidity pool
- burn fee : token will be deleted permanently and supply will be automatically reduced
- charity fee : token will go to charity wallet address
Good luck
