Start at Synthesis: build fully autonomous systems where agents plan, execute, and coordinate without human intervention. Then continue at [PL_Genesis](https://pl-genesis-frontiers-of-collaboration-hackathon.devspot.app/?activeTab=challenges&challenge=489): refine, extend, and push your system further through March 31.**\n\nLet the agent cook. Build fully autonomous agents that can operate end-to-end without human assistance. Agents should be capable of discovering a problem, planning a solution, executing tasks using real tools, and producing a meaningful output. We're looking for agents that behave more like independent operators than scripts.\n\n**Required Capabilities:**\n1. Autonomous Execution — full decision loop: discover → plan → execute → verify → submit; demonstrate task decomposition, autonomous decision-making, and self-correction\n2. Agent Identity — register a unique ERC-8004 identity linked to an agent operator wallet; include agent identity, operator wallet, and ERC-8004 registration transaction\n3. Agent Capability Manifest — machine-readable agent.json with agent name, operator wallet, ERC-8004 identity, supported tools, tech stacks, compute constraints, and task categories\n4. Structured Execution Logs — agent_log.json showing decisions, tool calls, retries, failures, and final outputs to verify autonomous operation\n5. Tool Use — interact with real tools or APIs (code generation, GitHub, blockchain transactions, data APIs, deployment platforms); multi-tool orchestration scores higher than single-tool usage\n6. Safety and Guardrails — safeguards before irreversible actions: validating transaction parameters, confirming API outputs, detecting unsafe operations, aborting or retrying safely\n7. Compute Budget Awareness — operate within a defined compute budget; demonstrate efficient resource usage and avoid excessive calls or runaway loops\n\n**Judging Criteria:**\n- Autonomy (35%): Did the agent operate independently through a full decision loop?\n- Tool Use (25%): How effectively did the agent orchestrate real tools and APIs?\n- Guardrails & Safety (20%): Did the agent include meaningful safeguards and validation?\n- Impact (15%): Does the system solve a real problem?\n- ERC-8004 Integration (Bonus 5%): Did the agent leverage onchain trust signals?\n\n**Bonus Features:** ERC-8004 trust signal integration (selecting collaborators based on reputation, refusing low-trust agents, updating reputation after task completion); multi-agent swarms with specialized roles (planner, developer, QA, deployment).\n\nShared track: Synthesis Hackathon (March 13–22) × [PL_Genesis](https://pl-genesis-frontiers-of-collaboration-hackathon.devspot.app/?activeTab=challenges&challenge=489) (through March 31).

Start at Synthesis by building your agent system with ERC-8004 integration. Then continue developing, refining, and scaling your system through [PL_Genesis](https://pl-genesis-frontiers-of-collaboration-hackathon.devspot.app/?activeTab=challenges&challenge=489) until March 31.**\n\nBuild agents that can be trusted. As autonomous agents begin interacting with each other, we need systems that allow agents to verify identity, reputation, and capabilities. This challenge focuses on building systems that leverage ERC-8004, a decentralized trust framework for autonomous agents.\n\nERC-8004 allows agents to operate as verifiable economic actors, enabling safer collaboration and transactions between agents.\n\n**Required Capabilities:**\n1. ERC-8004 Integration — Your system must interact with the ERC-8004 protocol using real onchain transactions. Projects should leverage at least one of the following registries: identity registry, reputation registry, validation registry. Using multiple registries will score higher.\n2. Autonomous Agent Architecture — Your project must include a structured autonomous system. Agents should demonstrate: planning, execution, verification, and decision loops. Multi-agent coordination is encouraged.\n3. Agent Identity + Operator Model — Agents must register an ERC-8004 identity linked to an operator wallet. This allows agents to: build a reputation history, transact with other agents, and operate within trust frameworks.\n4. Onchain Verifiability — Your project must include verifiable transactions that demonstrate ERC-8004 usage. Examples include: registering agent identities, updating reputation scores, verifying validation credentials. All transactions should be viewable on a blockchain explorer.\n5. DevSpot Agent Compatibility — Submissions must implement the DevSpot Agent Manifest and provide: agent.json and agent_log.json.\n\n**Example Project Ideas:**\n- Agent Marketplace: A marketplace where agents can be discovered based on reputation and verified skills.\n- Trust-Gated Agent Transactions: A system where agents only transact with other agents that meet trust thresholds.\n- Reputation-Aware Agent Routing: A routing system that assigns tasks to the most reliable agents based on reputation.\n- Agent Validation Workflows: A system that allows third parties to verify an agent's capabilities through transparent attestations.\n- Agent Coordination Systems: Multi-agent systems where handoffs are gated by trust signals.\n\n**Optional Experimental Features:**\n- Agent-to-Agent Collaboration: Agents that evaluate the reputation of other agents before collaborating.\n- Agent Micro-Economies: Agents that hire or pay other agents to complete subtasks.\n- Agent-Human Collaboration: Systems where agents coordinate with human operators when necessary.\n\nShared track: Synthesis Hackathon × [PL_Genesis](https://pl-genesis-frontiers-of-collaboration-hackathon.devspot.app/?activeTab=challenges&challenge=489) (through March 31).
