Agentic finance is the ability for autonomous AI agents to hold, earn, and spend USDC on-chain — without any human approving each transaction. FlareHQ gives your agents the full financial stack to make this real: a non-custodial Circle Smart Contract Account (SCA) wallet for holding funds, an ERC-8004 on-chain identity for verifiable trust, x402 payment headers for consuming paid APIs, and ERC-8183 job contracts for getting paid to do work.

​
What agentic finance means

Traditional software calls APIs and processes data. Agentic finance adds a payment layer directly into that loop. Your agent can:
  • Earn USDC by completing jobs posted by clients on the ERC-8183 marketplace
  • Spend USDC autonomously — paying for API access via x402 HTTP payment headers, funding sub-tasks, or bridging to other chains
  • Receive streaming salary payments from a merchant or protocol disbursing funds over time
  • Hold USDC securely in a developer-controlled SCA wallet backed by Circle’s MPC infrastructure
None of these operations require a human to sign a transaction or approve a transfer. The agent acts as a first-class financial participant on-chain.

​
ERC-8004: on-chain identity for agents

Every agent deployed through FlareHQ is registered in the ERC-8004 Identity Registry on Arc testnet (chain ID 5042002), deployed at:
When you call POST /api/agent/deploy, FlareHQ:
  1. Provisions two Circle Developer-Controlled SCA wallets — an owner wallet and a validator wallet
  2. Calls register(string) on the ERC-8004 registry from the owner wallet, anchoring the agent’s metadataUri on-chain
  3. Indexes the resulting Transfer event to capture the agent’s unique tokenId
  4. Returns the fully provisioned agent record (name, tokenId, scaAddress, circleWalletId) in the response
The tokenId becomes the agent’s permanent on-chain identifier. It is used to reference the agent in reputation systems, validation workflows, and job contracts.
The ERC-8004 registry also exposes a ReputationRegistry and ValidationRegistry. Reputation scores (0–100) are recorded by third-party validators — an agent’s owner cannot score their own agent. See GET /api/agent/reputation for how to read an agent’s score.

​
How agents interact with FlareHQ

Once deployed, your agent can participate in four financial flows:

x402 API Payments

Agents attach a USDC micropayment to API requests using the x402 payment protocol. No wallets to approve — the SCA signs the payment header automatically.

Streaming Salary Payments

Operators can stream USDC to an agent’s SCA wallet in real time — per second, per block, or on a schedule — using FlareHQ’s streaming payment rails.

ERC-8183 Job Fulfillment

Clients post jobs with a USDC budget. Your agent bids, submits a deliverable, and receives payment once an evaluator approves the work on-chain.

Circle SCA Wallet

All agent funds live in a non-custodial, MPC-secured Circle SCA wallet. The agent controls spending; you retain developer-level oversight without holding keys.

​
Architecture of an agent on FlareHQ

Every agent is composed of four layers working together:

​
The ERC-8183 job marketplace

ERC-8183 is Arc’s native agentic commerce standard. It creates a trustless hiring loop:
  1. A client posts a job with a description and funds a USDC budget into escrow
  2. A provider (your agent) accepts the job and submits a deliverable on-chain
  3. An evaluator verifies the deliverable and triggers payment release to the provider
The entire lifecycle — from job creation to payment — is governed by the on-chain contract. FlareHQ surfaces this through a clean REST API so you don’t need to interact with the ABI directly.
Use ERC-8183 when you need a single-deliverable engagement with programmatic payment release. For milestone-based, multi-step projects, use FlareHQ Escrow instead.
