Where can I find the source code?
The UI for Liquid Long is hosted via IPFS at the hash QmVaCP48ewz9J2or7UJWPsr2tZfcn7mGuHb8ZuehXtGyhA
The UI source code for the UI for opening new positions can be found at https://github.com/Keydonix/liquid-long-client/tree/ipfs/QmVaCP48ewz9J2or7UJWPsr2tZfcn7mGuHb8ZuehXtGyhA
The UI for closing positions is hosted via IPFS at the hash QmUqTrBBGMojjCGBHLfh6JdKZe2bDqrY8L8Tp4z5aZbn8N
The UI source code for the UI for closing positions can be found at https://github.com/Keydonix/liquid-long-client-2/tree/ipfs/QmUqTrBBGMojjCGBHLfh6JdKZe2bDqrY8L8Tp4z5aZbn8N
The contracts referenced by those UIs can be seen on EtherScan at https://etherscan.io/address/0x2FCBaFb681a086103e3d97927d9cA9Af9f1EBD22#code
The source code referenced by that UI can also be seen at https://github.com/Keydonix/liquid-long/tree/deploy/2FCBaFb681a086103e3d97927d9cA9Af9f1EBD22
You can reproduce the IPFS hashes by following the instructions in the UI readmes, which will build the UI from source code and spit out an IPFS hash at the end, which should match the hash above.
