Decentralized exchanges (DEXs) are innovative trading platforms built on blockchain technology that enable trading of digital assets without the involvement of traditional banks or intermediaries. Unlike centralized exchanges, DEXs give users complete control over their assets and trading activities. This decentralized structure ensures a transparent and censorship-resistant trading environment.
One of the key features of DEXs is that they do not require complicated identity verification procedures such as KYC (Know Your Customer). Users can begin trading immediately by simply connecting their wallet. This makes DEXs an ideal choice for privacy-focused users and traders seeking rapid transactions.
DEXs also automate transactions using smart contracts, significantly reducing the risk of human error and fraud. Leading DEXs such as Uniswap, Raydium, and PancakeSwap use the Automated Market Maker (AMM) model with liquidity pools, allowing users to trade at prices close to market value at any time.
In Japan, the Payment Services Act applies to DEXs depending on the nature of their services. Specifically, if a DEX intermediates transactions, manages assets, or provides price quotations as a business, it is required to register as a crypto asset exchange operator. These regulations are crucial for protecting users and safeguarding market integrity.
Regulations on DEXs are tightening globally, and Japan’s Financial Services Agency is monitoring DEX operations closely. Users should confirm that the DEX they use operates within the proper legal framework. It’s also essential to understand the principle of self-responsibility, and to practice strict risk management when using DEXs.
Many overseas centralized exchanges (CEXs) do not support deposits in Japanese yen. In addition, enhanced regulatory oversight from Japan’s Financial Services Agency has led to access restrictions for users in Japan. As a result, DEXs have become a popular alternative to overseas exchanges.
By using a DEX, users avoid custody risk—the risk of an exchange holding their assets. DEXs allow users to tap into global liquidity 24/7, enabling trading at any time and from anywhere. Another advantage is the ability to access tokens unavailable on domestic exchanges, such as Ethereum-based meme coins or new tokens on the Solana chain.
However, using a DEX requires wallet management and an understanding of gas fees (transaction fees). While the initial learning curve can be steep for beginners, understanding these basics enables more flexible and open trading.
Meme coins are cryptocurrencies born from internet meme culture, with value shaped by community support and viral attention. In recent years, many meme coins have been traded on DEXs, generating strong interest among investors. Below are some notable meme coins available on DEXs.
Floki Inu (FLOKI) is a meme coin launched in recent years, named after “Floki,” a Shiba Inu adopted by a well-known entrepreneur. Just after its debut, FLOKI’s market capitalization reached hundreds of billions of yen, and it has remained in the spotlight with listings on major exchanges and plans for metaverse game development.
FLOKI is available on multiple blockchains, including Ethereum, with the ERC-20 version being its primary market. This multi-chain approach allows users to move FLOKI across different blockchains, improving liquidity and convenience. FLOKI is also a community-driven project with active voting and events for holders.
FLOKI’s appeal goes beyond meme status, as the project is developing practical use cases. For example, integration with NFT marketplaces and DeFi platforms is underway, generating expectations for long-term value growth.
BONK is a Shiba Inu meme token launched on Solana during a period when the ecosystem was reeling from the collapse of a major exchange. Its founding slogan was to “revitalize the community.”
BONK’s most distinctive feature is the airdrop of 50% of its total supply (50 trillion BONK) to Solana users. This large-scale airdrop rapidly raised BONK’s profile in the Solana community. Over time, BONK has achieved significant growth, reaching a market cap in the hundreds of billions of yen.
BONK leverages Solana’s high speed and low transaction costs, enabling quick trades. It is integrated with many Solana-based DeFi projects and NFT marketplaces, helping to revitalize the ecosystem as a whole.
dogwifhat (WIF) is a meme coin on Solana, featuring a Shiba Inu in a pink knit hat. Its unique appearance drew attention on social media, causing its price to surge shortly after launch.
WIF’s maximum supply is fixed at about 998.9 million, with no additional issuance, staking rewards, or burning mechanisms. This simple, community-driven design is a key part of its popularity among investors.
WIF’s main strengths are its simplicity and enthusiastic community. By keeping the project straightforward and accessible, anyone can participate. Solana’s low fees and high speed also make trading WIF easy and cost-effective.
Recently, a prominent politician launched the official meme token “Official Trump (TRUMP)” on social media. On its first day, its market cap reached several trillion yen, attracting extensive global media coverage.
This was followed by the launch of “MELANIA,” the official token of the US First Lady. Both tokens generated significant buzz and attracted many investors in a short time, but they do not guarantee long-term value and are prone to sharp price fluctuations. Investors should proceed with caution.
Celebrity tokens can see temporary surges in demand due to media exposure and name recognition. However, it is critical to evaluate their utility and project sustainability carefully. Before investing, research the token’s background, purpose, and community activity thoroughly.
COCORO is Japan’s first officially recognized meme coin by “Kabosu Mama” (the photographer of the DOGE meme), launched in recent years. The coin’s motif is “Kokoro,” a black Shiba Inu rescued as the successor to the famous Dogecoin model “Kabosu.”
COCORO is issued as an ERC-20 token on Base, an Ethereum Layer 2 solution. This significantly reduces gas fees compared to Ethereum mainnet, making trading inexpensive. COCORO is typically purchased by swapping ETH on Uniswap.
COCORO is deeply rooted in the Japanese community, with robust Japanese-language support and events, making it accessible to domestic investors. Backed by Kabosu Mama’s official recognition, COCORO combines credibility and popularity.
Because most new meme coins are issued on Ethereum or Solana, having a MetaMask or Phantom wallet will allow you to access almost all such tokens. These wallets are user-friendly and compatible with many DEXs, making them a good choice for beginners.
For beginners, it’s best to start with small amounts. Keep risk low until you become comfortable operating a DEX. Use trusted sources like CoinMarketCap or CoinGecko to check the official DEX for each token and avoid fake tokens.
Be extremely careful with wallet setup and recovery phrase management. The recovery phrase is the only way to restore wallet access, and losing it may result in permanent loss of assets. Write it down and keep it in a safe place.
Ethereum mainnet gas fees are very high, making small swaps costly. In such cases, consider chains like Solana, Base, or BSC (Binance Smart Chain), which offer faster and cheaper transactions. These chains are ideal for frequent traders due to their speed and low fees.
Uniswap is one of the most popular DEXs on Ethereum. Here are the steps to buy a meme coin on Uniswap:
Buy Crypto on a Domestic Exchange: First, purchase ETH or another cryptocurrency on a domestic exchange, which accepts Japanese yen and is beginner-friendly.
Send Crypto to a Supported Wallet: Transfer the ETH to a wallet like MetaMask. Enter the destination address carefully and consider a small test transfer first.
Access Uniswap’s Official Site: Visit app.uniswap.org and click “Connect Wallet” in the upper right.
Connect Your Wallet: Choose a supported Web3 wallet (MetaMask, WalletConnect, Coinbase Wallet, etc.) and approve the connection.
Search for the Token: On the swap screen, search for the token by name or contract address. Confirm the contract address from official sources to avoid fake tokens.
Execute the Swap: Select the token to swap from (e.g., ETH) and the token to receive (e.g., FLOKI), enter the amount, set slippage tolerance, and click “Swap.”
Confirm the Transaction: Review the details in your wallet and approve. Gas fees will display—check the cost before proceeding.
Verify Completion: After the swap, the new token appears in your wallet. Check transaction history to ensure it was processed correctly.
Raydium is a popular DEX on Solana. Here’s how to buy meme coins on Raydium:
Buy Crypto on a Domestic Exchange: Buy SOL on a domestic exchange. SOL is Solana’s native token and is used for gas fees.
Open Raydium’s App: Visit raydium.io and select “Swap” from the top menu.
Connect Your Wallet: Connect a Solana-compatible wallet such as Phantom. Approve the connection and verify your wallet balance.
Select the Token: Choose the token from the dropdown or enter the mint address directly. Verify token details using official sources to avoid scams.
Execute the Swap: Enter the amount, click “Swap,” set slippage, and approve the transaction.
Transaction Approval: Once confirmed on-chain, your new balance will appear in your wallet. Solana transactions typically finish in seconds.
Keep these points in mind when swapping on Raydium:
Check Price Impact: Large swaps or illiquid pools can cause significant price impact. Always check “Minimum Received” before proceeding to avoid unexpected losses.
Set Slippage Appropriately: Slippage is the difference between expected and executed price. Generally, a 1–5% range is recommended, but adjust based on liquidity and market conditions.
If you see a “TimeOut” error, the transaction may not have reached the blockchain. Raising the priority fee can help your transaction process faster.
Also check for network congestion. If the network is overloaded, wait and try again later. Solana is usually fast, but can be slow during heavy usage.
PancakeSwap is a popular DEX on Binance Smart Chain (BSC). Here’s how to buy meme coins with PancakeSwap:
Buy Crypto on a Domestic Exchange: Buy BNB on a domestic exchange. BNB is BSC’s native token and is used for gas fees.
Prepare a BSC-Compatible Wallet: Set up a wallet like MetaMask for BSC. You’ll need to add the BSC network manually.
Connect MetaMask to BSC: In MetaMask settings, add the BSC mainnet with the appropriate network details.
Open PancakeSwap’s Official Site: Visit pancakeswap.finance and connect your wallet via the “Connect Wallet” button.
Open the Swap Screen: Click “Trade” then “Swap” in the top menu.
Select Tokens: Choose the token to swap (e.g., BNB) and the token to receive (e.g., BONK). Enter the contract address to find a specific token.
Execute the Swap: Enter the amount, click “Swap,” review the confirmation screen, then click “Confirm Swap.”
Approve the Transaction: Confirm and approve the transaction in MetaMask. Gas fees will be shown—confirm the cost before proceeding.
Set slippage (acceptable price range) appropriately when using a DEX. Too low can cause failed trades, too high can result in unfavorable prices. A range of 1–5% is common, but adjust for liquidity and market conditions.
Ethereum network fees can rise sharply, reaching several thousand yen for small trades. Consider using Layer 2 solutions such as Solana, Arbitrum, or Optimism for lower costs and faster transactions while maintaining Ethereum’s security.
Meme coins can deliver high returns but involve significant risks. Consider the following when buying meme coins:
Scam tokens imitating popular coins are widespread on DEXs. Many have names or tickers similar to “PEPE” or “SHIB,” so caution is required.
To avoid scams, always confirm contract addresses via official websites or trusted sources like CoinGecko and CoinMarketCap. Do not interact with suspicious tokens. Be especially careful with tokens promoted on social media or those with sudden price spikes.
When searching for tokens on a DEX, check liquidity and trading volume. Extremely low-liquidity tokens are susceptible to price manipulation and may not trade at fair prices when selling.
The meme coin market is highly volatile, with drops exceeding 50% from all-time highs in some periods.
As the number of meme coins rises rapidly, many lose value quickly. One survey found that 97% of meme coins have failed, underscoring their speculative and short-lived nature.
Sharp price swings are common until liquidity stabilizes. Only invest what you can afford to lose without affecting your daily life.
Meme coins derive value from community enthusiasm more than utility, so carefully evaluate project sustainability. For long-term investment, thoroughly research the project’s background, development team, and community activity.
Meme coins are attractive for their buzz and potential but carry risks such as volatility and fake tokens. Since many are not listed on domestic exchanges, DEXs are a viable option if you understand their mechanisms and legal frameworks.
Familiarize yourself with wallet and network settings, as well as gas fees, to trade safely on DEXs. Carefully manage slippage settings and always verify token contract addresses to minimize risk.
Remember, meme coins are high-risk speculative assets. Approach them carefully, monitor market trends closely, and make investment decisions at your own risk. Beginners should start with small amounts and increase investment as they become more comfortable with DEX trading.
Above all, enjoy meme coin investing but avoid excessive risk. Engage with the community and support project growth for a more rewarding investment experience.
Meme coins are cryptocurrencies inspired by internet memes. They are popular due to low entry costs, strong communities, and viral momentum on social media. Their entertainment value and speculative opportunities attract many investors.
Connect your wallet to a DEX, search for the meme coin, enter the amount of crypto to swap, and click the swap button. Pay the gas fee and approve the transaction to complete your purchase.
Dogecoin, Shiba Inu, Neiro, and DOGS are currently notable meme coins. These are community-driven with steady trading volume. Keep an eye on new tokens and overall market trends as well.
Prepare a TRON-compatible wallet (like TronLink) and hold TRX. Swap TRX for meme coins on a DEX. Always verify contract addresses with official sources to avoid scams.
Meme coins are highly volatile and driven by speculative demand. Utility is limited, so always investigate project credibility and invest only what you can afford to lose.
DEXs are decentralized and do not require intermediaries, while CEXs are centralized and hold assets in custody. DEXs offer more security but may have slower transaction speeds, while CEXs are faster but at higher risk of hacks.
Use contract audit tools (such as RugCheck) and track the creator’s wallet. Do not trust unknown projects and always confirm the reliability of information sources.
