What a USDC transfer actually costs on Base, Polygon, Arbitrum, Ethere
What a USDC transfer actually costs on Base, Polygon, Arbitrum, Ethereum and XDC, measured rather than assumed: gas units simulated per chain against live prices and fresh chain heads, plus the rollup L1 data fee where it applies. Every figure ships with its inputs and the block it was read at, so you can recompute it. Cheapest first; a chain that cannot be measured is excluded, never estimated.

Realised 30-day yields for 13 tokenized treasury funds: BUIDL, BENJI, OUSG, USDY, USTB, USYC, VBILL, mTBILL, TBILL, cUSDO, EUTBL, USTBL and UKTBL. Measured rows use NAV, price or verified passive-holder balance series under the published Open Treasury Yield Basis. Each carries its observations, sources and dates, plus an issuer figure and difference where available. Quoted and unavailable rows stay explicit; free coverage names every gap.
