Flowy -- Stream NFTs across chains in real-time @ 1 click

Thanks! 😊

What it does?

• With Flowy, you can stream NFTs across chains in real-time.
• For instance -- send + change a number automagically from one chain to another @ each second literally.

How it works?

Using some smart contract magic (wink, wink)

• Flowy’s smart contract has dynamic token URI (stored as on-chain function)
• Deployed across EVM chains (currently Goerli + Polygon Mumbai)
• Basically, NFT is changed on a per second basis -- aka streaming

How it's made?

Using Connext + Push Protocol + Smart Contracts

• Data is streamed by passing a stream reference (linked with block timestamp)
• Stream Reference changes token URI as per set time interval (currently 1 second)
• Flowy’s smart contact co-ordinates with chains to ensure a seamless flow

Future Work

• Link data to colors (RGB + more)
• Add nested update feedback
• Simultaneous Chain Support

Test 1 -> Hello World!

• Optimism -- 0x199F32709630345d701Ec3d072eC816cab33f2f5

Test 2 -> TOKENS MISSING -- Tokens were sent from Mumbai Testnet, but they didn't reach Goerli -- if you find them, please send them @ 0x20136F73c536Db9D061b078146D7694cd4Bd0aEA address.

• Optimism -- 0xEBDe845A1b3496e8Bac65b12A666E09C13ae1cC4
• Mumbai -- 0x6521CBd89b00B05c74D5CCa6EBA313E2fcC5bBa7

Test 3 -> CONNEXT WORKED -- now, I need to focus on how to actually stream NFT, fr.

• Optimism -- 0x7bD14F022b13D0d49bC1b9d2F6d4b9E522f73220
• Mumbai -- 0x313daf6A19669353a331AE47e5D625aC5A2b0413

Test 4 -> SOMETHING WORKED -- basically data was being sent + received.

• Optimism -- 0x10618819DDbECAa8c41614B8E84B5d84FacA8980
• Mumbai -- 0x99573EaebdbA8B8f7245a424ef60BAA30ae142AE

Test 5 -> 404 -- don't know what happened here.

• Optimism -- 0x9FF4F30AF7F5E09d8fe1732002ce541b37456Ad2
• Mumbai -- 0x3F1DD9E63820BBB5F891491DB09164e6B90719EB

Test 6 -> SOMETHING COOL JUST HAPPENED -- ain't gonna reveal here the suspense here, check out the code :)

• Mumbai -- 0x8F188C69F7a368d2eFeab4F48becFc7134cd398E

Test 7 -> TOKENS MISSING PART 2 -- back to the same problem of Test#2, damn.

• Optimism -- 0x58c173Cb71EB14f40997A209e3dA004Fd85eaB9B
• Mumbai -- 0x2A74C6a761FE076585664678fbAF2A233510f102

Test 8 -> MYSTERY SOLVED -- it was the authorization problem in contract.

• Mumbai -- 0xb460582cD86d379eAC0a8dF9E3a0D33AE445aD0D

Test 9 -> TOKENS MISSING PART 3 -- it was not the authorization problem.

• Optimism -- 0xaA2E1F629619cADf34ba2e78cEd8dD348ad9f399
• Mumbai -- 0xD387157e10EF1B772E7e207466BB9f1dA46FD0D7

Test 10 -> TOKENS MISSING PART 4 -- at this point, I was about to give up, but I didn't -- not gonna let that damn TEST token decide the fate of this project.

• Optimism -- 0x00bc4406ED97643FD98eE7b65D2a17e339eF3B1f
• Mumbai -- 0xDD7bB344dA9793da270d55ccDb3a192F72D51947

Test 11 -> DAMN! -- it was the problem of Connext's bridges; if you send token from Polygon to Optimism, then they go missing (something fishy going on with Connext's bridge on Polygon) -- but if you send from Optimism to Polygon, it works.

• Optimism -- 0x29022Ef6818CD2e2A70a10B278695BD555ba8b1b
• Mumbai -- 0xEA32B11df38BeeBB3f22c81a46eB8D07FaeB284B

Test 12 -> PIVOT -- moved to Goerli (coz' Optimism betrayed me) + added Push Protocol

• Goerli -- 0xfF44095dcc42205c49D6d317056853D08c9B451c
• Mumbai -- 0x23aA8D82Befb7EA722F2EbE461c6F5A3FaB7652b

Test 13 -> TESTING -- notifications are working, we are good for launch -- cap'n

• Mumbai -- 0x10a0358e48D56Dcc38A0047Ce834e02834B4bb16

Test 14 -> NOTIFICATION MISSING -- when stream was sent -> notification was received BUT when stream was received -> notification was not received, huh.

• Goerli -- 0x1ec713728479B84Af6038DE2aA9cfE666c0B2725
• Mumbai -- 0xE13439d4a9B2279F406a0bC40Cc491B5602692B0

Test 15 -> EUREKA! -- everything works, FINALLY!

• Goerli -- 0x6C7132d30167F39Ef6DA9287916d09A5962b8E51
• Mumbai -- 0x0029754f88896E3FE639Dad25c1460223231F032
