DeFi literacy: TVL & protocol health
DeFi protocols are on-chain businesses, and their books are open. TVL (total value locked) shows deposits; fees show real usage; emissions show how much of the 'growth' is just token printing. A protocol earning real fees with sticky TVL is a business. One renting TVL with emissions is a promotion.
Free to play. No ads, no token, no account needed to start.
What you get asked
TVL doubled in a month. The critical follow-up question is:
Or did emissions just rent mercenary capital that leaves when rewards dry? Mercenary TVL follows the highest bribe. Fee revenue is the metric that can't be rented. It's your 'where does the yield come from' question, aimed at protocols.
Match the DeFi metric to what it reveals
Your stock-valuation instincts transfer directly: protocols have revenue multiples too, and comparing them across similar protocols finds the outliers.
Smart-contract risk means even a healthy protocol can lose funds to a single ___.
Billions have vanished through code bugs and bridge hacks. Audits reduce but never erase this. DeFi position sizing must price a nonzero chance of total loss.
A protocol pays 60% APY funded entirely by its own token emissions, price of that token falling. This is…
Yield in a melting currency, your League 3 yield forensics in action. Real APY = stated APY minus reward-token depreciation minus IL minus gas. Run that math and most farms turn negative. The calculator is your armor.
The mature stance on DeFi for a Formiga graduate:
Engage with sized positions, audited bluechips first, and books-open analysis. Frontiers reward the prepared and harvest the reckless, same as every market you've studied. Boss next. 🐜
