Gm Gm chat! so I’d love to drop my takeaways from the just concluded HackCanton S3, from what i actually loved this season, down to issues i faced and of course some builder tip so you dont waste time on things that Ive already figured out. So for S3, @umbraoncanton focused mainly on decentralisation of our node, as centralisation already showed how bad it could be when your only node is down, and what I loved this season, was how the @BitSafe_Finance's team actually showed up, and assisted with the co-hosting of our parties, on their node. They actually stayed with the node-down run even after the first attempt failed, and that genuinely meant a lot to us! The @appsfactory_cc team were also super active and i could see how they swiftly attended to other participants' issues kudos to the team. So, down to challenges I faced this season, the one that actually stood out, was with the wallet integration, where i found out that every wallet signs differently, so even when dealing with just 4 wallets, and those wallets wanted the same 32-byte hash, they all kinda wanted it in 4 different shapes, so for instance, 1 decodes base64 itself, while another straight up wants it wrapped by its own SDK, another UTF-8 expands a bare string before signing. So basically, if not careful, you just find out withdrawals or basic transactions silently do nothing, and unfortunately, most of our integration time went there, not even into the Daml lol. With all these said, what i genuinely feel would help S4, is, • A link to documentation holding details about exactly which bytes a wallet should sign, with sample hashes to check against if possible (Im actually working on setting up a public repo for this later too). • Again, links to docs for the one ledger permission an externally-signed trade needs before it can execute. And now as a developer on Canton this might help you save some time actually; • I’d advise you run tests against 2 wallets from day one, because 1 working wallet proves nothing lol except if you only plan to integrate 1 single wallet though. • Record the demo before deadline hours this is actually very important, as a poorly made demo could miss lots of key points that judges watch out for. But in all, the builds this season were really at the top, and it was really nice listening to you guys pitch yesterday🫡🫡

Umbra won the BitSafe Gold track at HackCanton S3! The moment that actually stuck with me the most this season, was switching our own node off and watching a trade still settle live on DevNet through BitSafe's node. Decentralization really did stop being a slide thing, and became a property of @UmbraOnCanton . Big thanks to the @BitSafe_Finance team, and @appsfactory_cc. Congrats to all the winners and finalists this season the builds this season were unreal. Upwards only📈
