What Is Onchain Trading?
Onchain trading is the act of buying, selling or exchanging digital assets via transactions which are recorded straight onto a blockchain itself. Rather than having to rely on a single central company to administer trades in a private database, onchain trading employs blockchain networks and intelligent contracts to process all activity.
The term 'onchain' simply signifies that a transaction actually occurs upon the blockchain itself - thereby forming an integral component of its publicly accessible record. Users are usually able to validate a given transaction via a blockchain explorer tool.
Onchain trading is very extensively utilized within Decentralized Finance (DeFi). It provides cryptocurrency users with the ability to swap out their tokens, engage in trading of assets themselves, offer liquidity, and also engage with various other financial applications all from compatible digital wallets themselves.
Why Was Onchain Trading Created?
Early cryptocurrency trading became popular via centralized exchanges. These platforms really simplified the process of purchasing and selling digital assets - although users themselves generally had to store their funds in accounts under the control of the exchange.
Blockchain developers developed decentralized trading systems as an alternative option.
Their objective was for individuals to be able to trade digital assets while retaining complete control over their crypto wallets. Instead of having to ask a company to update its internal balance, an on-chain trade moves assets through a blockchain transaction itself.
Such an approach really embodies the broader concept of Decentralized Finance: developing financial services that will run using open-source software - rather than relying almost entirely upon the traditional intermediaries.
How Does Onchain Trading Work?
An on-chain trade will start when a user links their self-custody cryptocurrency wallet to a decentralized application.
The user picks out the assets they wish to trade and views essential details - including estimated price, network fees and potential price impact. Then the wallet will ask the user to sanction the transaction itself.
Post-approval the transaction is sent off onto the blockchain network. Validators or other participants within the network process it in line with the blockchain's rules themselves.
A smart contract might then conclude the trade itself by moving tokens between your wallet and a liquidity pool or some other trading system. Once verified the transaction forms part of the blockchain record itself.
Exactly how this process works itself out will depend on the specific network and the trading protocol being used.
What Role Do Decentralized Exchanges Play?
Decentralized exchanges - known as DEXs - are among the most popular platforms for trading on-chain.
Many DEXs will be using liquidity pools instead of a traditional order book. A liquidity pool comprises tokens supplied through smart contracts. Traders can swap assets with these pools themselves whilst liquidity providers may get a share of the trading fees.
Other on-chain trading platforms use blockchain-based order books that match buyers and sellers much more directly.
Both models aim to let users trade via transparent blockchain infrastructure itself - without having to give up control of their assets entirely to a centralized exchange.
Onchain Trading vs. Centralized Exchange Trading
The main difference lies in the place where the trade is registered and who holds control over the assets themselves.
On a centralized exchange trades will often occur within the company's own internal system itself. Blockchain transactions generally happen when users put in or take out their cryptocurrency.
With on-chain trading, the actual transaction itself is performed by way of blockchain infrastructure. Users themselves normally link up their own digital wallets and verify each and every transaction.
This results in much greater transparency and self-custody, but at the same time also puts more power into the user's hands. A wrong transaction or interaction with a deceitful smart contract may prove very difficult - or even impossible - to turn back.
Benefits of Onchain Trading
Transparency is really one of the key benefits. Users are able to verify transactions, smart contract activity and liquidity data themselves via the public blockchain records most of the time.
Self-custody is yet another very important feature. Traders will be able to keep hold of their private keys instead of storing all their assets with an exchange.
On-chain markets will also be able to operate 24/7 and may give you access to a whole host of blockchain-based assets.
For more experienced users this makes for a far more open and programmable trading environment itself.
Risks of Trading Onchain
Trading on a blockchain is accompanied by quite high risks.
Smart contracts might be affected by bugs or some sort of security weakness. Counterfeit tokens and malicious web sites will try to take your money whilst poor liquidity will result in either a very high price impact or 'slippage'.
Network fees themselves can become costly whenever there's a lot of action on the blockchain.
Because most transactions are final, users really have to check their wallet addresses, token contracts, network details and also all information about the transaction itself very carefully.
Why Onchain Trading Matters
On-chain trading really shows off blockchain technology's capabilities when it comes to creating transparent, programmable and accessible financial markets - all accessible right from your digital wallet.
Its value lies well beyond simple token exchanges themselves. The very same infrastructure could be used for decentralized lending, derivatives, prediction markets and many more sophisticated financial services.
As blockchain tech itself continues to develop, what's in store for on-chain trading in the future will depend on better security, an even simpler user experience, a deeper pool of liquidity and clearer regulatory frameworks. Grasping the fundamentals of how it all works is a key first step for anyone wanting to get to grips with decentralized finance and markets based on blockchain.
