smart-contracts for the swap functionality

bitcoincom-solidity-swap

This repository contains smart-contracts for the swap between token A and token B or token A to ETH / ETH to token A.

Process and Testing

The package can be run as a CLI for testing purposes.

🔗 First start a local chain:

npm run chain

Then run test commands for contract deployment and testing

🚀 This command runs token tests:

npm run test-token

🌯 This command runs wrapped ether tests:

npm run test-wraps

🏭 This command runs swap router / swap factory tests:

npm run test-swaps

Test coverage

🧪 To generate test-coverage report simply run this command (without starting local chain)

npm run test-coverage

Hola

Dear Bitcoin.org,

Dear Bitcoin.org, 

Greetings, I hope this find you well. I have an issue that needs an explanation.

When I tried to download the Bitcoin White Paper from your website [Bitcoin.org]. I noticed a blockage. I did not get the PDF paper, even from Google search link. How is it Google can get the paper and I can't? Could you please amend your ways and give me an explanation? (Read the Images attached).

By the way, if you are unable to change. It could be read as payload and harassment for sick gains!!! If that is so, I guess, is that why you are in hiding! lol

Thank you,
PS: Where is the blue paper? lol

The Images and content are the copy right of the owners.
