Basis Cash · interactive mechanism simulation

A Uniswap TWAP oracle reads the BAC price. Above peg, new BAC is minted to repay bonds then pays Boardroom shareholders (who sell it). Below peg, holders burn BAC to buy discounted bonds — but only if they believe the peg will recover. Edit the parameters, or trigger a confidence crisis, and watch the flywheel respond.

Illustrative simulation. Mirrors the researched Basis Cash mechanism (BAC/BAB/BAS three-token seigniorage-shares model, ~24h Uniswap TWAP oracle, ε peg band, bond-funded contraction, Boardroom-funded expansion) but prices, supply and bond-buyer behavior are randomized and simplified for visualization — not live onchain data. The "trigger confidence crisis" button dramatizes the death spiral described in the entry's Outcome section; it is a hypothetical demonstration, not a record of the actual 2021 collapse.
