Deposit USDC from any Ethereum wallet — MetaMask, Rainbow, or anything over WalletConnect — and receive U. The protocol buys the unit's exact contents on-chain at that moment: dollar stablecoins, tokenized T-bills, gold, tokenized US equities, bitcoin, tokenized real estate and credit, in the quantities fixed by revision R1. Burn U and the contents come back — in kind, or swapped to USDC at the live U rate. No rate oracle stands in between; the price of U is what its contents cost. How the mechanism works, and its safety math. The contract is in build (testnet milestone E-1); the quotes below are live from the index today. Fees are the symbolic f, with terms published separately.

The token contract (a standard ERC-20 with mint/burn against the basket) ships in milestone E-1 — see the build spec.

deposit USDC → receive U at the U rate
burn U → the contents back, in kind or swapped to USDC
Why Ethereum: every leg of revision R1 already exists there as a real token held outright — dollar stablecoins (USDC, USDT, PYUSD), tokenized T-bills (BUIDL, USDY, OUSG), gold (PAXG, XAUt), tokenized US equities (bCSPX, Ondo Global Markets), bitcoin (WBTC, cbBTC) and tokenized real estate and private credit (RealT, Centrifuge). Nothing is carried synthetically. The unit is a portfolio of those assets, so its dollar price moves with them and can fall; the 20-year backtest of this composition returned +4.44%/yr above world inflation with 5.9% annual volatility and a worst drawdown of 12.0%.
