BRC & BRX Tokenomics
Every number on this page comes from the consensus source code or is read live from the chain. Emission is paid at consensus boundaries, not per block, and is capped by a hard 330,000,000 BRC supply.

Circulating supply counts only BRC that has left the six distribution wallets (Public Sale, Liquidity, Private Sale, Marketing, Ecosystem, Airdrops). Reserve, foundation, treasury and validator wallets accumulate rewards but are not counted as circulating.

Rewards halve every 47,304,000 blocks (9 × 10,512,000 ÷ 2 ≈ 4.5 years at 3-second blocks) by an exact right-shift (reward ÷ 2era), decaying toward zero with no floor. The geometric total of 106,482,667 BRC plus the 194M genesis leaves a safety margin of about 29,517,333 BRC under the 330M cap. Regular blocks mint nothing; validators earn the gas fees of the blocks they seal.

BRX is minted by the staking contract when rewards are claimed, so its supply is exactly the rewards paid out to date. It is fingerprinted by Token DNA on every transfer and trades against WBRC on BirrDEX. Contract 0xDc267E…8C01cd · vault 0xBb0821…E90DA9.
