token2049's own faq: 60%+ of its 25,000 attendees are c-level or founders.

i went as a student. four things got me further than the badge did 🧵

[alex @frytegg]

what the week was about: tokenization and agents.

x402 has settled ~$42m across 192m payments. 22 cents each on average, tests included.

the rails are ahead of the demand. so who's building the return counter?

[alex @frytegg]

4. keep iterating.

twice that week, the project that made a stranger lean in was orma, from september. not the one i'd just built.

[alex @frytegg]

3. go to the rooms where you feel out of place.

best advice of the week, on a rooftop full of suits: quantify the risk on the protocol. for an institution, every operation is a risk.

best conversation: a check-in queue at changi, on the way home.

[alex @frytegg]

2. believe the judges and sponsors.

day one, in writing: the use case isn't clear. we spent two days building a better answer. two hours finding a better question would have done more.

[alex @frytegg]

1. do the hackathon.

130 of 200 builders at origins went to the cardano track: ai agents that pay. masumi said it in august: everyone built the checkout, nobody built the return counter.

@0XAndrea_ and i built the return counter. we didn't place. https://t.co/5XrRTNjS6J

built brume at @token2049 origins last week, cardano track.

the escrow that pays ai agents has a dispute branch. it works fine. it just needs an arbitrator, and that arbitrator hasn't signed anything since november 2025.

61 escrows are still sitting in it. ⬇️

who owns your context in your company ?

[alex @frytegg]

so happy to have shipped this project alongside @elibenbaruk, whose work was impeccable

anyone who understands that context is the real currency in the agentic ai era will thrive in any project they build

Badge makes context sharing inside companies safe

[DeVinci Blockchain @DeVinciBC]

🧑‍💻 Our @Ledger N3XT hackathon build is in !!

@elibenbaruk and @frytegg shipped Badge: each employee's Ledger becomes their company badge for AI agents.

No context leaves without its owner's signature.

@DeVinciBC @Ledger @elibenbaruk lfg 🚀 @elibenbaruk is such a good builder

@token2049 code, every transaction hash and a 7-page annex with the proofs:
https://t.co/CA1ncc0hz4

built on @MasumiNetwork's vested_pay contract. mainnet numbers pinned to a census block in the repo. we didn't place.

if you know how to measure a front-run cleanly, i'm listening.

@token2049 what it doesn't do: pre-signing kills the refusal, not the race. once leg 1 lands the buyer can still broadcast a competing exit. we never got a clean window to measure that, so the solver prices it at worst case.

[alex @frytegg]

@token2049 so brume builds the exit that doesn't need one.

two transactions, signed before either is sent. the seller concedes, the buyer has already signed the split, so there is nothing left to refuse.

12 settlements on preprod, 24 legs, no admin key in any of them.

[alex @frytegg]

@token2049 the number that stopped me: across all 120 arbitrations that contract has ever seen, the seller side was paid in 0 of them.

not rarely. zero.

[alex @frytegg]

went to the @Ledger n3xt student gathering and conference, at SMU in Singapore.

always nice to see many student’s community thriving

can’t wait for this week Op3n here in paris, in the Ledger HQ

see you there 👀

[alex @frytegg]
