we built breaker for the
@solana stocklana hackathon.
on september 17th, the SEC started letting real US stocks trade on public blockchains
but there's a condition almost nobody is talking about:
when nasdaq halts a stock, every venue trading its token has to halt it too.
on solana, nothing does that today.
the issuer halts the stock, but the token keeps trading.
we checked every stock xstocks has halted right now, and not one of them is paused on chain.
any pool holding them would keep filling orders at a price the market hasn't set.
@breakersec is infra for exchanges, protocols and liquidity pools.
it's one call a venue adds to its swap, and before any token moves it checks what the SEC order requires:
→ is the stock halted?
the trade is refused
→ is it over its daily volume limit? refused
→ did it pass? the trade is published on chain, in dollars
if any check fails, the whole trade reverts.
it covers all 1,124 xstocks tokens, with the halt feed mirrored from the issuer every 5 minutes.
the demo below shows the same order sent with and without breaker while the stock is halted.
every run is a real transaction on solana devnet that you can open yourself.

The SEC just let real US stocks trade on public blockchains.
But when Nasdaq halts a stock, its token keeps trading on chain.
We built Breaker to fix that.
