swap 0.1.0

Cross-chain atomic swap between the networks of two Cryptocurrencies.

Swap

Swap is a python library for cross-chain atomic swap between the networks of two Cryptocurrencies. Cross-chain atomic swaps are the cheapest and most secure way to swap Cryptocurrencies. It’s a brand new decentralized payment environment based on Hash Time Lock Contracts (HTLCs) protocol.

Available Cryptocurrencies

Swap has the following available Cryptocurrencies to swap:

Cryptocurrencies	Mainnet	Testnet	Solonet
Bitcoin BTC	Yes	Yes	None
Bytom BTM, Assets	Yes	No	No

Benefits of HTLC's

There are many benefits to these types of contracts. First, because they are time sensitive, it prevents the person who is making the payment from having to wait indefinitely to find out whether or not his or her payment goes through. Second, the person who makes the payment will not have to waste his or her money if the payment is not accepted. It will simply be returned.

• Time Sensitivity · The time sensitive nature of the transaction prevents the sender from having to wait forever to find out whether their payment went through. If the time runs out, the funds will just be sent back to the sender, so they don’t have to worry and can wait for the process to unfold.

• Trustless system · As is the case with all smart contracts, trust is not needed as the rules are already coded into the contract itself. Hash Time Lock Contracts take this one step further by implementing a time limit for recipients to acknowledge the payment.

• Validation of the Blockchain · Transactions are validated because of the cryptographic proof of payment required by the receiver.

• Private Information's · There are no complicated account setups or KYC/AML restrictions. Trade directly from your wallet with a counterparty of your choice. Only the parties involved know the details of the trade.

• Trading across multiple Cryptocurrencies · HTLC makes Cross-chain transactions easier and more secure than ever. Cross chain transactions are the next step in the evolution of Cryptocurrency adoption. The easier it becomes to unite the hundreds of blockchain's that currently exist in silos, the faster the technology as a whole can begin to scale and achieve mass adoption.
