Crypto has changed considerably over the past decade. Buying Bitcoin once meant navigating unfamiliar exchanges and wallets, while moving between cryptocurrencies on different blockchains could require even more technical knowledge.
Today, someone looking to swap BTC to ETH or BTC to SOL has far more options. Centralized exchanges remain widely used, but decentralized exchanges, bridges, aggregators and cross-chain protocols have created new ways to move between assets and networks.
That progress has made crypto more capable. It has not necessarily made it less complicated.
allblu is approaching that problem by focusing on the experience around the swap. Rather than requiring users to understand every piece of infrastructure involved in a cross-chain transaction, the platform brings the process into a single swap flow while still showing information such as the expected amount, fees and minimum received.
From Centralized Exchanges to Cross Chain Swaps
For years, centralized exchanges were one of the most accessible ways to move between cryptocurrencies on different blockchains.
Someone holding Bitcoin who wanted Ethereum, for example, would typically have to:
- Create and verify an account with a centralized exchange.
- Deposit BTC into the exchange.
- Wait for the Bitcoin deposit to be credited.
- Trade the BTC for ETH, either directly or through another trading pair.
- Enter an Ethereum withdrawal address.
- Withdraw the ETH back to their own wallet.
For users already trading on an exchange, this process can still make sense. But for someone holding Bitcoin in their own wallet who simply wants ETH in another wallet, the process introduces an exchange account and several separate actions between the asset they have and the asset they want.
Crypto infrastructure has since evolved.
Users can now interact with decentralized exchanges, bridges, aggregators and protocols capable of coordinating transactions across multiple blockchains. Instead of always depositing assets onto a centralized platform first, there are now ways to complete many of these transactions onchain.
What Is a Cross Chain Swap?
Consider a BTC to ETH swap.
To the user, the intent is simple:
BTC → ETH
But Bitcoin and Ethereum exist on separate blockchains. Moving from one asset to the other requires infrastructure capable of coordinating a cross-chain transaction.
Behind the scenes, liquidity and execution can involve an intermediate asset. A route could effectively look like:
BTC → USDC → ETH
The user, however, does not necessarily need to manage each part of that route individually.
This is the part of the process allblu is designed to simplify. Instead of asking the user to execute multiple trades, the platform presents the transaction as one BTC to ETH swap.
allblu handles the underlying routing and liquidity behind the swap. Today, this can include Just-in-Time, or JIT, liquidity, where liquidity is sourced in real time when a swap is needed. The underlying route can remain more sophisticated, while the user sends the requested asset and receives the destination asset in their wallet when the swap completes.
There is no account or signup required to create a swap, and the user does not have to manually manage the intermediate liquidity route.
That does not make a crypto transaction risk-free. Markets can move, blockchains can experience delays and decentralized infrastructure carries its own risks. Simplifying the transaction flow does not eliminate those realities.
Instead, the approach reduces how much of the underlying process the user has to coordinate themselves.
Understanding Slippage and Minimum Received
Crypto prices can move while a swap is taking place, and different blockchains have different confirmation times. The market price when a quote is created may therefore be different by the time the swap executes.
This is where slippage and the minimum received amount become important.
Slippage allows for a certain amount of price movement during the swap, while the minimum received shows the lowest amount the user is willing to receive if the market moves within the permitted range.
allblu includes the expected amount, minimum received and applicable fees in the quote so users can review the expected outcome before starting the swap.
It is a relatively simple approach to an important part of onchain trading: users should be able to see what they are sending, what they are expected to receive and the minimum amount they could receive before proceeding.
Making Cross Chain Swaps Easier to Understand
Another barrier to cross-chain swaps has little to do with liquidity or blockchain infrastructure. Many people simply have not made one before.
Terms such as destination network, slippage, deposit address and minimum received can make an otherwise simple transaction feel unfamiliar.
allblu also includes an interactive how-to-swap guide aimed at making the process easier to understand. Rather than relying entirely on static instructions, the guide uses live quotes and lets users explore supported asset combinations before starting a transaction.
Someone interested in swapping BTC to ETH, for example, can explore the pair, see a live quote and become familiar with the information involved without having to create a swap.
It is a useful addition for newcomers because understanding how a cross-chain swap works should not require understanding every liquidity mechanism operating underneath it.
Making the Complicated Part Simpler
Cross-chain technology has advanced considerably, but the user’s goal can still be remarkably straightforward.
Someone has BTC and wants ETH. Someone has BTC and wants SOL.
The technology required to make that happen across separate blockchains can remain complex underneath. The experience presented to the user does not have to be.
That is ultimately where allblu is positioning itself: making cross chain swaps easier to understand and execute while allowing the more complicated routing to happen in the background.
