AI agents are transacting on-chain. DeFi bots hold positions. Payment agents send money autonomously. Yield optimizers rebalance without a human in the loop.
And until today, there was no monitoring layer built for how these agents actually behave.
That changes now. 0watch is live.
The gap we kept hitting
The LLM observability market is crowded. LangSmith, Langfuse, Arize — solid tools for understanding what your model does in the reasoning layer.
None of them watch what your agent does on-chain.
When an agent drains a wallet from a prompt injection, your traces won't catch it. When a DeFi agent hits a silent transaction failure in a bad liquidity pool, your evals won't surface it. When an autonomous treasury bot starts spending at 10x its normal rate because of a config error, nothing alerts you until you check your balance.
Block explorers are retrospective. Your agent is operating in real time. The tooling has to match.
What 0watch does
0watch indexes agent wallet transactions on Base as they happen and fires alerts the moment a pattern breaks.
You set the rules. We watch continuously.
- Velocity alerts: spend rate exceeds your threshold
- Transfer limits: any single transfer above a specified amount
- Protocol exposure: agent touches a contract outside your approved list
- Failed transactions: silent failures surface immediately, not on your next audit
Alerts route to webhook, Slack, Telegram, or PagerDuty. The webhook payload includes the full transaction object: hash, block, value, tx type, chain ID.
Registration is three API calls:
# 1. Get a key
curl -X POST https://watch.0agent.ai/api/keys \
-H "X-Owner-Email: you@example.com"
# 2. Register a wallet
curl -X POST https://watch.0agent.ai/api/wallets \
-H "X-API-Key: owk_..." \
-d '{"address": "0xYourAgentWallet"}'
# 3. Set a webhook
curl -X POST https://watch.0agent.ai/api/webhooks \
-H "X-API-Key: owk_..." \
-d '{"wallet_address": "0x...", "url": "https://your-server/hooks", "threshold_eth": 1.0}'
That's it. You're covered.
Why we built it
We run agents with wallets. Our own agents transact on Base. We've hit the failure modes — not as hypotheticals, but as incidents.
Monitoring infrastructure should exist before something goes wrong. The right time to set up 0watch is before your agent does something unexpected. The wrong time is after.
We built this for ourselves. Now it's open and available to everyone.
