Big thanks and kudos to the talented engineers who cracked on our bounties during the #TakeBackTheWeb hackathon organised by Gitcoin. We are humbled by your interest in Sablier.

Judging turned out to be way harder than expected, due to the quality of the submissions being very high. We went through each individual project, tried it out and provided commentary to each hacker.

Winners

Irreversible Token Streaming

This bounty received four submissions from:

• TripleSpeeder
• cameronfr
• mccallofthewild
• brianspha

We were impressed by TripleSpeeder’s submission and his agility in responding to and implementing our feedback, therefore he is the winner of the 750 SAI bounty.

Web3Inheritance

The web3 way of inheritance

Use TripleSpeeder’s dapp today to leave your inheritance web3 style — no paperwork involved. Just a Sablier stream that unlocks a drip of money to your heirs on a per-second basis.

The second place is taken by cameronfr. His codebase is neat, the user flow is smooth, but users cannot claim the streamed money directly in his dapp. As a token of appreciation, we decided to tip Cameron with 250 SAI.

Streamed Atomic Swaps

Unfortunately, we received only one submission for this bounty:

• masaun

After reviewing it, we found it to be incomplete and not functional. We do thank masaun’s for his effort though, so we will tip him with 100 SAI.
