Built on @arc
For the @nansen_ai Meridian Buildathon, I built NOCK.
2026 has been brutal for on-chain money.
April 1: Drift on Solana lost $285M in 12 minutes.
April 18: Attackers drained $292M of rsETH from Kelp’s bridge, used it as collateral on Aave and borrowed roughly $190M in ETH.
Aave itself wasn’t hacked yet $8.45B left the protocol within 48 hours and DeFi TVL dropped $13B in two days.
September 24: Bitget lost $351.6M from its hot wallets and paused withdrawals.
The exploit takes minutes but damage can spread for hours and leave a devastating impact
I built NOCK for those hours.
NOCK watches the vaults, yield dollars, and lending markets where people park capital across Ethereum, Arc and Robinhood Chain using live @nansen_ai data.
Instead of using one generic threshold, NOCK measures every venue against its own normal behavior.
When wallets start leaving unusually fast NOCK detects a run.
When suspicious or stolen collateral starts spreading into lending markets, NOCK detects contagion.
We replayed the Kelp incident using Nansen data.
NOCK’s contagion alarm fired at 17:42 UTC 78 minutes before major WETH lenders rushed to exit.
On Stream xUSD the run alarm fired 7 days before withdrawals froze.
But detecting risk isn’t enough.
NOCK can act.
You place your deposit behind a small guard contract controlled by your wallet.
If NOCK raises an alarm on that vault, a keeper can call exit() and return the funds directly to your wallet.
That is the only action the keeper is allowed to perform.
I tested the full flow on Arc testnet:
Deposit → drill → alarm → exit → funds back home → Telegram transaction alert.
NOCK also adds a safety layer for copy trading.
Before copying a wallet, you can see who entered first and whether early wallets sold into the traders who followed.
This week on Solana, NOCK identified 25 early wallets selling into buyers who arrived after a smart trader’s entry.
And agents can use all of this too.
Add the NOCK MCP to Claude Code or Codex.
Once the free credits are exhausted, agents can pay $0.02 per call in USDC on Arc via x402.

late gms are allowed right
@karwanBuild would be going live on a controlled mainnet on @arc today
expect more details later today.
all our contracts responsible for holding money are undergoing final stage of internal audits, once it passes we would be live fully on arc mainnet on a later date
been working day and night to bring this to life... expect more update from us soon
with just 2 days to @arc mainnet we can already see the signs
the team just rolled out points for in-person events and it’s a juicy one.
I can see @bobbilee is working to make architects ready for mainnet 🤍
my little mainnet wish is for @silencexlm to make me present @agonmarkets in the discord office hours 🥹
Build on arc.
g m chat
feels so good to be back and what a way to start the week
- @arc mainnet in 2 days
- ArcRun now Agon (@agonmarkets) made the shortlist for the ignyte hackathon
- finally left my toxic job 😮💨
- a close friend who was kidnapped has been released
- back to the gym
I wrote about agent portable memory a month ago Agent Memory Is an Ownership Problem https://t.co/FKACyrggYN
and built agentqa that uses memwal remember and recall storing and recovery of agent memory via walrus.
found a bug which was addressed: https://t.co/pGEFbPdm7B
good to see walrus becoming main pushers in portable memory for agents
A major update in regards to the rebranding of ArcRun will be coming soon
This is in line with the arc branding guidelines.
That said, we will be live on the 16th of September when mainnet goes live
Countdown begins
There are many builders on @arc This is just a spotlight on a few of them, in no particular order.
I initially wanted to cover 15 to 20 builders but honestly this took way more time and energy than expected, and I am currently sickish on my bed as I post this🤣
Happy weekend 🥂
