I gave a research presentation on Flash-Mintable Asset-Backed Tokens (new DeFi primitive).
Includes discussion about their properties, compare/contrast to flash loans, and a live bug bounty.

Or just check out the README in the Flash-Mintable repository:
fWETH contract live on mainnet
The Flash-Mintable Wrapped-Ether (fWETH) contract is live on mainnet. It has the same public API as WETH (is intended to work as a drop-in replacement for WETH).
Bug Bounty contract
The Bug Bounty contract (a constant-sum, AMM exchange contract that lets you trade fWETH for ETH on a 1-to-1 basis with no fees and no slippage).
If you can find a way to break the economics you can steal all of the money from this contract.
I think that’s about as far as I’m going to take this research project. Feel free to use it, fork it, ignore it, or whatever. If you do decide to pick up the torch and run with it, feel free to reach out if you want to discuss some of the more subtle design decisions.
