BTCB/USD price feed

This feed prices Binance-Peg Bitcoin: a token on BNB Chain, issued by Binance, backed one to one by bitcoin the issuer holds in reserve with public attestations. The backing is the issuer's undertaking; what the pools pay for the token is the market's reading of it. This page carries the second number.

The precision matters because the name does not travel cleanly. More than one token answers to this symbol across chains, at prices orders of magnitude apart, so a casual lookup can land on a different asset entirely. A feed settles that the boring way, by naming exactly what it measures: the composition below is the answer to which BTCB, at every block.

One thing this page does not claim is that BTCB is bitcoin. It is a claim on bitcoin, carried by an exchange's reserve, priced continuously by an on-chain market. Keeping those three things separate is what lets each of them be verified on its own terms.

BTCB exists so that an ecosystem with its own applications, its own dollar venues, its own native coin can trade bitcoin without leaving home. A home-chain book is therefore not a gap in coverage; it is the asset doing what it was minted for. This page measures that market at whatever size it currently runs.

The quote side shows who the host is: a chain's ecosystem prices its bitcoin in the dollars it settles in plus, at times, in its own coin. Bitcoin priced in its host's currency is the distinctive number a home market can produce; where such a leg exists, the feed reads it on the host's terms.

The flow is serious: weekly volume through these pools has run to nine figures. A footnote for readers of market structure: wrapped bitcoins sometimes price each other directly, two representations of one asset trading at the edge of a number.

A rate built from a home market raises a fair question: what keeps it honest? The same things that keep any rate honest. The book is read across whatever quote families it holds, each leg converted to dollars at one pinned block, so legs of different natures cross-check one another before the aggregate exists.

Coin-quoted legs deserve a sentence of their own. A pool that prices BTCB in the chain's native coin knows nothing about dollars; the feed resolves such a leg through that coin's own measured dollar market at the same block, so every step of the conversion describes one moment. No part of the number is borrowed from outside the measurement.

For teams building on BNB Chain it is the local Bitcoin number; for everyone else it is a clean reading of what one ecosystem pays for bitcoin.
