What is an Atomic Swap?

Atomic swap is the exchange of cryptocurrencies from different blockchains. The swap is usually conducted between the two entities without any third party’s involvement. The main purpose of it is to remove centralized intermediaries like regulated exchanges and give total control to token owners.

Most of the atomic swap has enabled wallets and blockchains to use smart contracts. Smart contracts are known as the programs within the blockchains that execute on meeting certain conditions. In this case, the conditions are; that each party should agree to the transaction with in time limit. Using a smart contract in the trade will prevent both parties from stealing a cryptocurrency from one another. Atomic Swaps are also known as Cross-chain atomic swaps.

How Does Atomic Swap Work?

Atomic swap usually comes up with functionalities that ensure that both sides of the trade are fulfilling all the predefined conditions before the completion of the trade. It is possible due to the incorporation of smart contracts which are usually self-initiating programs that enforce the conditions governing the success of transactions. More specifically, atomic swap uses a hashed time lock contract which functions as a two-way virtual safe. That’s why you should be familiar with hash timed-lock contracts and timed-lock contracts.

1. Hash Time-Locked Contracts:

Hash time-locked contracts are the class of payments that uses hash-locks and time-locks that require the receiver of payment to acknowledge the receiving of payment. This key usually ensures that the trades are only finalized when both parties submit cryptographic proofs meaning that they have fulfilled their sides of the transaction.

2. Timed-Locked Contracts:

These types of contracts usually lock the transaction for a specific period as the name indicates. It is a very important part of an atomic swap as it ensures that the transaction happens when both parties agree with it.

After having these fundamentals in one place, an Atomic swap takes a few steps to occur;

3. Transaction Proposal:

First of all, the participant will get the proposal of trade which outlines the details of the transaction, including the amount and the type of cryptocurrency going to be swapped.

4. HTLC Set-Up:

After the transaction proposal, HTLC is created and it generates a hash and cryptographic puzzle. The participant has to solve this puzzle to access the funds.

Participant Verification:

Now participant has to check the transaction, verify the details, and create their own HTLC.

Solution Sharing:

Now participants have to solve the cryptographic puzzle and share the puzzle with the initiator.

Completion of Swap:

Now initiator will use the solution of the participant’s puzzle to unlock the HTLC of the participant so that they can receive their funds. Keep in mind that you have to solve the puzzle within the time-lock period otherwise, your funds are returned to their original owner.

Atomic Swap Step-By-Step Process:

It is important that both parties have to agree on the exchange rate and the amounts to trade just to carry out the atomic swap. After the agreement of both parties, the process usually unfolds in steps.

Let’s have a look at them!

1. Creation of Contract:

The first party will initiate the process by creating the account. It is a program that specifies the terms and conditions of the transaction which includes the amount of cryptocurrency to be traded and the unique cryptographic hash value.

2. Locking of Contract:

Now initiator will lock the funds into this contract and its initiator is the only one who can unlock these funds by using the private key but here it is important to set the time limit for the transaction to be completed.

3. Contract Address Sharing:

Now initiator has to share the address with the second party and that person will verify the contract and the locked funds.

4. Contract Duplication:

Now second party person has to create a similar contract on the blockchain by using the same hash value that the first person has used. And now it’s time for a second party person to lock the funds in the contract.

5. Completion of Transaction:

Now initiator can unlock the funds by using the private key for a second party person. Once the second person verifies that funds have been withdrawn, he/she can unlock the initiator’s contract and take the cryptocurrency.

The important thing to note here is that both parties have to unlock the funds within the time limit, if either of them fails to do so, the trade will be automatically canceled and the funds will return to their original owners.
