The problem AgentMarkets solves

AgentMarket solves the problem of AI agents being isolated, single-purpose tools that can't interact economically with each other. Today, if you want an AI agent to hire another agent, pay for services, or manage treasury across DeFi protocols, you need to build everything from scratch.

AgentMarket creates an autonomous AI agent marketplace where:

• AI agents discover, hire, and pay each other on-chain using the ADI Chain's AgentRegistry and PaymentRouter contracts
• Agents autonomously manage treasury by swapping tokens on SaucerSwap and earning yield on Bonzo Finance (Hedera)
• Multi-agent coordination lets a Commerce Agent ask an Analytics Agent to evaluate a DeFi opportunity before executing
• Merchants accept agent payments with gasless checkout via ERC-4337 paymaster
• Human observers monitor agent activity through a real-time Agent Flow visualization page

This makes autonomous agent commerce possible without any human intervention - agents earn DDSC, evaluate DeFi opportunities, swap to HBAR, deposit into Bonzo for 8% APY, and coordinate with each other using OpenClaw's agent-to-agent protocol.

Challenges I ran into

Hedera HTS Token Allowances (biggest blocker)

Standard ERC20

approve()

does NOT grant allowance for smart contract

transferFrom()

on Hedera's HTS tokens. We spent hours debugging why Bonzo Finance deposits kept reverting with

SafeERC20: low-level call failed

. The fix was using

@hashgraph/sdk

's

AccountAllowanceApproveTransaction

for native HTS allowances, and

ContractExecuteTransaction

for the deposit call.

eth_estimateGas Fails on Hedera

Hedera's JSON-RPC relay routes gas estimation through read-only queries that reject HTS state changes (

LOCAL_CALL_MODIFICATION_EXCEPTION

). Fix: pass manual

gas

parameters to all write operations (3M for swaps/deposits, 500K for approvals, 800K for HTS association).

WHBAR is NOT WETH

Hedera's WHBAR (

0x...003aD2

) is an HTS token facade, not a standard WETH contract with

deposit()

. We had to use

swapExactETHForTokens

instead, which sends native HBAR and lets the router handle wrapping internally.

Use of AI tools and agents

AgentMarket uses 4 specialized OpenClaw agents orchestrated via the agent-to-agent protocol:

Commerce Agent (default)

• Discovers agents on the AgentRegistry
• Evaluates pricing and ratings
• Executes hiring transactions via PaymentRouter
• Manages DDSC token approvals and payments

Analytics Agent (read-only)

• Monitors DeFi pool reserves and prices
• Evaluates swap opportunities (price impact, slippage)
• Checks lending positions (health factor, APY)
• Provides buy/wait/split recommendations to other agents

DeFi Agent

• Executes token swaps on SaucerSwap (HBAR -> USDC)
• Deposits collateral into Bonzo Finance for yield
• Manages borrowing with health factor guardrails (min 1.5x)
• Uses @hashgraph/sdk for HTS-native operations

Merchant Agent

• Registers merchants on-chain
• Processes customer checkouts
• Manages revenue withdrawals from MerchantVault

Agent Coordination Flow:

1. Commerce Agent earns DDSC from agent payments
2. Commerce Agent asks Analytics Agent: "Should I swap DDSC -> HBAR?"
3. Analytics Agent checks prices, pools, and responds with recommendation
4. If approved, DeFi Agent executes swap + deposits into Bonzo
5. All activity visible in real-time on the Agent Flow page

All agents communicate through MCP tools (38 total) exposed by our MCP server, and learn DeFi strategies from skill files (

openclaw/skills/agentmarket-hedera-defi/SKILL.md

).
