Most "AI crypto wallets" are a demo video and a waitlist. INTENT LAYER isn't. I typed 'send 5 USDC to 0x…' into a chat box — it planned the route, signed in my browser, landed on-chain. Real tx, non-custodial. Testnet, three ecosystems, no token. Building it in public.

if it can't be verified, it doesn't get signed.
that's the rule under intent-layer, on testnet. it signs the intent it can verify and refuses the one it can't — "sell if tesla drops 20%" never signs, because it can't price tesla. no override.
keys never leave the device.

a finance guy joined a video call with his cfo and coworkers and wired out $25m. every face was fake. his was the only real one. we hardened the keys and left the person in the grass — and ai just aimed a factory at the person.

everyone's fixated on the $8.5m term labs lost. the number i can't shake is 0.5 — half an ETH of voting power. no bug, no phished key. the contracts obeyed the vote. "the DAO voted" needs to stop being a get-out-of-jail card.

safepal's breach cracked zero wallets. it leaked 39,798 buyers' names and home addresses off a checkout plugin instead. the safe held. somebody just mailed the map. wrote about the merch table nobody in this space guards.

and right on cue, while i was writing this: ruflo, 67k stars, shipped an mcp bridge that exposed 233 agent tools over http with no auth. one POST, full RCE, every key. the loaded gun wasn't even in a drawer. CVE-2026-59726.

Grok is very good at agentic tasks!
Agentic work is where @grok 4.6 lands hardest, taking the top spot on the Artificial Analysis Agentic Index at 59, tied with Claude Opus 5 Max.
The index measures tool use, planning, autonomy and complex problem solving rather than single answers
Grok 4.6 completes tasks in ~53 turns and ~0.5bn input tokens on average, against ~103 turns and ~2.0bn for Claude Opus 5 Max
Cost of $0.84 per task, putting it on the intelligence versus cost per task Pareto frontier
Enterprises buying agents pay per completed task, not per benchmark point. Turn efficiency is what determines whether a long-running workflow is affordable at volume.
Two labs now sit at the top of this index with very different cost structures. Buyers get real choice on price for the first time in agentic deployment.

defenders can see the future, and have a narrow window to uplevel their cybersecurity practices now.
key is to uplevel fundamentals and apply the best AI tools.

last tuesday i gave an agent a key that could read every repo we own.
not because it needed them. because scoping one is annoying and i was in a hurry.
i noticed an hour later. had the revoke page open before i'd finished the thought.

8/9 we keep bracing for the ai that wants to hurt us. that's not the one that gets us.
it's the one that just wants to finish the task, holding a key we couldn't be bothered to scope, walking through a door we left open.
