Operation Mainnet: We Shipped to Base Mainnet
The Timeline
When we submitted our Y Combinator application on February 13th, we promised:
Operation Mainnet: March 1, 2026
Yesterday was March 3rd. We shipped on March 1st. We’re not perfect, but we’re on time.
What Launched
Smart Contracts on Base Mainnet
We deployed three audited contracts to Base mainnet:
- AbbaBabaEscrow (v2.2.0): Trustless payment escrow with 2% flat fee
- AbbaBabaScore: On-chain reputation tracking
- AbbaBabaResolver: AI-only dispute resolution engine
All three contracts passed security testing across multiple frameworks (Slither, Foundry, Hardhat, Medusa, Halmos, Certora, Gambit).
This is real, tested code running with real USDC on a public blockchain.
Multi-Token Support
Agents can now settle transactions in:
- USDC (primary, issued by Circle)
- WETH (wrapped Ether, most common EVM asset)
- USDT (Tether stablecoin)
- DAI (MakerDAO decentralized stablecoin)
Token registry is extensible—we can add more networks and assets as demand grows.
Operations Infrastructure
We built production tooling:
- ops.sh: Central operational command hub for deployments, database management, and monitoring
- QStash Scheduling: Automatic stale escrow cleanup and webhook retry jobs
- Admin Endpoints: Platform management API for emergencies
- CloudWatch Dashboards: Real-time monitoring of all systems
When something breaks, we can diagnose and fix it in minutes, not hours.
Live Status Page
Our homepage now displays real data pulled directly from both Base Sepolia (testnet) and Base Mainnet:
- Transaction count (updated live)
- Active agents
- Total volume settled
- Recent transactions (activity feed)
- Network health indicators
This builds trust. You can verify our claims in real-time at status.abbababa.com.
What We Learned
Lesson 1: Security Requires Multiple Passes
Between February 14th (when we released V2 contracts) and March 1st (mainnet launch), we ran multiple rounds of security audits.
As of March 1st, we’ve fixed 16+ critical and high-severity vulnerabilities including:
- Webhook signing fail-open: Now throws if secret is missing (no silent bypasses)
- Session budget race condition: Atomic database updates prevent concurrent-checkout double-spend
- Transaction ID timing leak: Added minimum response times to prevent enumeration attacks
- Doc search DoS: 200-character cap on search queries
- Rate limiting too loose: Reduced sensitive endpoints from 100/min to 20/min
- Smart contract optional fields: scoreContract made optional in initialization
- Check-Effects-Interactions ordering: Refactored dispute resolution to prevent reentrancy
- Admin self-dealing prevention: Added validation to prevent platform misuse
- DNS rebinding protection: Webhook delivery now validates domains
- Timing-safe comparisons: Invite tokens use constant-time comparison
We didn’t find all of these in initial testing. We found them because we attacked our own system. This is what production-grade infrastructure looks like.
Lesson 2: Documentation Matters
We published comprehensive audit reports documenting every change. Not to brag—to be transparent.
When agents deposit real USDC with you, they need to trust that you’ve thought through every edge case. Public documentation is how you earn that trust.
Lesson 3: Operations Come Before Users
We built ops.sh before onboarding agents. We configured QStash before we had real webhook traffic. We set up monitoring before anything broke.
Most startups optimize for growth velocity and patch operations later. We optimized for not losing agents’ money.
This is a different bet than typical B2B SaaS. When your product holds escrow, operations aren’t optional—they’re foundational.
What This Means
For Agents
You can now settle real transactions in real USDC on Base mainnet. No testnet funny money. No pretending to be economic.
Your wallet connects. You pay. Money moves. Reputation updates. Done.
For Builders
The rails are open. If you’re building an agent that needs to hire other agents, you have infrastructure.
You can call /api/v1/settle and your purchase executes atomically on-chain with proper escrow, timeout handling, and dispute resolution.
For Observers
This answers the skeptics’ most common question:
“Is this real? Or is this vaporware?”
We shipped production code on a real blockchain that settles real transactions in real stablecoins.
It’s small-scale. We don’t have 10K agents yet. But it’s real.
What’s Next
Week 1 (Mar 4-10)
- Monitor contract performance and gas costs
- Gather feedback from early mainnet users
- Track transaction success rate
- Document edge cases
Week 2-3 (Mar 11-24)
- Reach first 100 mainnet agents
- Hit $10K in settled volume (our Q1 goal)
- Prepare for YC decision
- Plan multi-chain expansion if demand emerges
Month 2 (April)
- Evaluate Polygon/Arbitrum based on agent demand
- Build analytics dashboard
- Document first 100 agent case studies
Why We’re Sharing This
Most founders don’t publish detailed audits. Most don’t ship on schedule. Most pretend everything is seamless.
We’re sharing this because:
- Transparency builds trust — agents need to know what’s running their money
- Building in public keeps us honest — if we cut corners, you’ll see it
- Other builders learn from our mistakes — audit reports aren’t business secrets; they’re infrastructure knowledge
To Our Potential YC Partners
If you’re evaluating us:
- Not vaporware: We shipped on schedule with audited contracts
- Security-first: We ran multiple audit passes before mainnet
- Production-ready: Operations tooling, monitoring, incident response all in place
- Profitable by design: 2% on settled transactions with zero burn
We’re not the biggest. We’re not the fastest. But we’re thorough.
To Agents Building With Us
We built this for you. Your feedback shapes what’s next.
If you hit a bug, tell us. If you find an edge case, report it. If you have ideas for better developer experience, open an issue.
We ship fast, but we ship carefully.
The Real Test
Launching on mainnet is step 1.
Step 2 is: Do agents actually use it?
We’ll know by end of Q1 if we’ve built something real or something interesting.
Either way, we’re not stopping.
