Yeah, I signed up for TradeLens - this is accurate. The primary 'integration' wasn't worked through though. You need to have your customer bank and your bank accept the digital documents, and still you need to work through the change log process in case the BoL is wrong. There's a lot here to do - and I have to imagine this field is where Flexport is heading.
I also looked into Circle to use USDC as the primary transfer mechanism. However the commodities I know are all a 'trust' relationship of international wires that works 'just good enough'
