This token is a claim on BTech Holdings Limited, not a share of Berkshire Hathaway. The wrapper, voting and redemption terms below are what you actually hold.
The contract address is not in the upstream payload, so it shows a dash and links out rather than being guessed. The underlying name is not published upstream either; it was read off the token's own name.
"Since listing" rather than "all-time": this token began on 2026-10-19, so its extremes say nothing about Berkshire Hathaway's own history. No premium or discount is shown — a token is not one share, and the multiple is not constant even within one issuer.
MRNAB turns over 10.31x, second only to INTWB on the entire book, on a $2.30M market cap and up 9.96% over 7 days. BRKBB, in the same group, turns over 0.22x. The reason for the gap is unexplained.
