Contracts, none of them ours
Morpho Blue, its Adaptive Curve rate model, its Bundler3 and its GeneralAdapter1 are Morpho's own work. Uniswap's router and quoter are used for two things only: turning ETH into dollars, and checking each market's oracle against a price from outside Morpho. Multicall3 is used to read a whole board at a single block.
Libraries
ethers v6, for encoding calldata and typed-data signatures, from cdnjs. Nothing else: the rate model, the placement and the transaction builder are this site's own files, and all three are plain, dependency-free JavaScript so that the tools and the page can run the same code.
The chain
Robinhood Chain, id 4663, an Arbitrum Orbit chain. The dollar is Global Dollar (USDG), issued by Paxos. Tokenized equities on it are Robinhood's.
