[0] "A network fee of 2.5% (with a cap of $500) will be deducted from your investment amount for settlement, custody, and trading costs associated with your payment in USDC". Very cheap indeed.
[1] [2] Blockchains offer no guarantees off-chain. Everything that happens in the real world boils down to the oracle problem. You need trusted third parties in supply chains, a cryptographic signature would essentially achieve the same thing.
Fair critique — AngelList is pretty aggressive with its fees. If you're willing to handle settlement + custody yourself, it's much cheaper.
The oracle problem is very real (and solvable). Even ignoring the ability to transact within the same system where provenance is maintained, I tend to think that trusted third-parties moving their supply chain operations into a public ledger which is verifiable across time is more advantageous than point-in-time cryptographic signatures.
