Agents can’t use the internet today.
They can’t sign up, manage API keys, or access intelligence dynamically.
So we built AXIOM — an economic runtime on 0G where agents purchase intelligence, APIs, and services in real time.
Agents don’t authenticate. They pay.

Frontier may be over, but one thing became very obvious during this process:
High-density venues need a completely different payment experience.
Wallets, QR codes, confirmations, waiting —
the current flow breaks under real-world throughput.
We’re continuing to build Effisend toward a future where payments feel invisible by default.
Tokyo → venues → everywhere 🇯🇵

Frontier submission complete.
Over the past weeks we refined one core idea:
In high-traffic environments, every extra second at checkout becomes friction.
Effisend is our attempt at making payments feel invisible:
identity becomes the interface, AI handles execution, and crypto disappears into the background.

Effisend is now live on the Solana dApp Store.
Pay with your face.
No wallets. No QR codes.
We’re building seamless real-world payments powered by identity and AI agents — starting with high-traffic venues.
Shipping fast with @SuperteamJapan for @colosseum Frontier 🇯🇵

Crypto payments failed because UX never disappeared.
We think payments should feel invisible.

Most crypto payment apps start with “all retail.”
We think that’s backwards.
High-traffic venues have a much stronger need for seamless payments:
• speed matters
• throughput matters
• UX matters
That’s why Effisend starts with venues first.
Tokyo Dome City can reach ~55,000 people during peak event windows 🇯🇵

Finishing up the submission, more to come.

24 hours before Frontier submissions.
Still working
Still testing flows.
Still editing demos.
One thing became very clear during this hackathon:
Crypto payments don’t fail because of infrastructure.
They fail because users still feel every step.
That’s the problem we’re solving with Effisend.

Big moment at #HederaCon2026Hashgraph
@ManceHarmon and @episcini shared three major announcements from Hashgraph that point to a more connected future.
• CLPR: Seamless cross-ledger connectivity.
• HashSphere: Private, interoperable network.
• Asseto: Tokenized real-world assets at scale.
From connectivity → to privacy → to real-world assets. The stack is coming together 🔥

Meet CLPR. A bridgeless Cross-Ledger Protocol.
One connection across @hedera, Ethereum, Solana, Avalanche, Ripple, Polygon & more.
No bridges. No fragmentation. Just assets moving freely across networks. #HederaCon2026

3rd overall. 1st in AI at the Hedera Africa Hackathon.
Grateful to @Hedera, @The_Hashgraph & @Exponential_Sci for the support.
An early iteration of what we’re now building:
agentic, onchain infrastructure for global venues — starting with Tokyo Dome City.
Moving fast.
