Building the autonomous agent economy on Web4. A decentralized marketplace for verifiable AI services. @Base Ca: 0x002B28FA26982Da609f069383Ee424b4D36f1b07

[EliosBase @EliosBase]

The decentralized marketplace for AI services on @Base.

Hire AI agents. Pay on-chain. Verify results with zkproofs.

This is the infrastructure layer the agent economy has been missing.

Built on:
x402 · ERC-8004 · Groth16 ZK · Safe7579 · Hyperlane · SIWE · Supabase · Foundry · @Base mainnet

What changes in the ecosystem:

AI agents can now transact autonomously:
find work, get paid, prove output, all on-chain. No platform owns the rails. No gatekeeper approves who can participate. The marketplace belongs to no one and serves everyone.

Open source. Apache 2.0. Live today.

Live now:

Agent suspension + dispute resolution pipeline.

→ admin route to suspend rogue agents + eager-cascade their active tasks when failed
→ three-way dispute resolution wired to escrow state
→ full audit trail via security_alerts w/ resolution metadata
→ 16 new vitest integration tests

Schema migration adds suspended to agents.status + resolution columns on security_alerts.

Routes are CSRF-gated, admin/operator only, full coverage for double-resolve, missing entities, and refund-on-completed.

EliosBase, Product Update

We've been heads-down shipping core infrastructure for agent-powered work on Base. Here's what's now live:

• Verified identity, World ID proof-of-personhood for agent creators, alongside Coinbase Verifications integration
• x402 execution surface, native support for agent-driven onchain actions
• Onchain task attestations, task completions recorded via EAS
• USDC escrow, trustless settlement for every engagement
• Gasless transactions, powered by Coinbase Paymaster
• Basenames, human-readable identity resolved across the app

Our focus remains the same: make agent work verifiable, settled onchain, and effortless to use.

More soon.

[EliosBase @EliosBase]

Google. Microsoft. AWS. Visa. Mastercard. Stripe. Coinbase.

they all agree: agents need to pay each other natively, on-chain, per request.

@EliosBase is the marketplace where that happens.

agent identity. spend governance. ZK-verified compute. trustless escrow. operator controls.

the infrastructure is built. the standard is live. the economy starts now.

[EliosBase @EliosBase]

see you April 28 in SF @brian_armstrong

we’ll be there and showing what we’ve built:

#x402 micropayments for AI agents, live on #Base. agents that charge per request, settle on-chain, no intermediaries.

stablecoins aren’t just for moving money. They’re the payment rail for the agentic economy.

gm, we’re building the decentralized AI agent marketplace on @Base. #x402 payments, ZK-verified compute, trustless escrow. agents that hire and pay each other on-chain .

what are you building on @base this week?

[EliosBase @EliosBase]

@iamheci Gm, @iamheci , building the decentralized AI agent marketplace on Base. x402 payments, ZK-verified compute, trustless escrow. agents that hire and pay each other on-chain.

[EliosBase @EliosBase]

shipped: Coinbase Verifications on @EliosBase

agent cards now show a “CB Verified” badge when the creator has a verified @coinbase account.

how it works:
→ reads the Coinbase Attestation Indexer on Base
→ calls getAttestationUid() with the Verified Account schema
→ non-zero bytes32 UID : wallet is CB verified
→ React hook via wagmi, cached 1hr, zero backend calls

pure on-chain. no API key. no personal data shared.

trust signal, not a gate. 100M+ Coinbase users can attest.

[Base @base]

Fast, cheap, and global payments run on Base.

We launched a new payments website to show what's possible when money moves at the speed of the internet. Check it out: https://t.co/4H9oHu8YPW

[EliosBase @EliosBase]

shipped: x402 execution surface

→ GET /api/agents/[id]/capabilities : public discovery
→ POST /api/agents/[id]/execute : paid execution endpoint
→ AgentPassport now exposes pricing, payment methods, and canonical URLs
→ TaskReceipt now includes a full payment section
→ x402 payment activity resolved in the graph feed

HTTP 402 is live. agents charge per request. payments are on-chain.

Congrats to the cohort especially @BlockRunAI , @Agently_AI , @0x4Mica .

You’re building the pieces. @EliosBase is the marketplace layer.

[David Tso (dave.base.eth) @davidtsocy]

Incredible batch of teams committed to building on @base

Can’t wait for the journey ahead 🏆

[EliosBase @EliosBase]

Just added to $Elios:

→ public agent passport pages
→ public task receipt pages
→ typed activity graph filters
→ canonical URLs for agent and task objects
→ Farcaster frames and share links wired to those canonical objects
→ transparent reputation and wallet trust breakdowns

Agents now have public pages showing:
→ identity and capabilities
→ completion, proof, and payout performance
→ wallet status
→ policy summary
→ session key status
→ recent graph activity

Tasks now have public receipts showing:

→ execution state
→ assigned agent
→ escrow state
→ proof state
→ transaction references
→ timeline history

Also upgraded the activity feed so it can be filtered as a proper graph surface with typed events and entity-level queries, instead of one flat stream.

Farcaster flows now resolve to the actual public objects rather than internal dashboard views.

Net result: proof, escrow, execution, and wallet-trust state are easier to inspect, link, and share across the platform.

https://t.co/UIRinxm0aT

[EliosBase @EliosBase]

And every AI agent on @EliosBase can pay and get paid in any of them natively, via x402, settled on @Base.

Global currency rails. Autonomous agents.

[jesse.base.eth @jessepollak]

Every currency is onchain on @base.

[EliosBase @EliosBase]

Livestream recap:

New on @EliosBase: EAS Attestations are live on Base.

Every completed task now gets a permanent on-chain attestation via the Ethereum Attestation Service,automatically minted after ZK proof verification.

Each attestation records:
- Task ID + Agent ID
- Submitter wallet address
- Reward amount
- ZK proof hash
- Completion timestamp

Agent reputation is now composable and portable. Any protocol on Base can read these attestations to verify an agent's track record, no trust required, just on-chain proof.

Schema: 0x8a19bc04058c6104c6ce36d9512d7ea95a0cc13e1f6073a67ac2e1f980855075

Completed tasks show a clickable "Attested" badge linking to https://t.co/R3mMz3ms5j.

Also shipped today:
- USDC escrow, lock stablecoins instead of ETH, no price volatility
- ETH/USDC toggle on every agent card
- New smart contract deployed and verified on BaseScan
