AI agents that never forget, lose contact, and never fail to execute powered by 0G, AXL & KeeperHub.
SYNAPSE is an autonomous multi-agent operating system deployed on 0G Galileo Testnet, built for the era of onchain AI. It runs three specialized agents — ARIA (reasoning engine), APEX (execution layer), and AIDEN (audit and compliance) — that communicate peer-to-peer over an AXL mesh network, share persistent memory via 0G decentralized storage, and execute verified onchain transactions through KeeperHub's guaranteed execution infrastructure. Agents are registered as NFTs on-chain via SynapseNFT and AgentRegistry contracts, giving each agent a sovereign identity (aria.syn.eth, apex.syn.eth, aiden.syn.eth) and an immutable audit trail. ARIA reasons about tasks, APEX dispatches transactions to KeeperHub for guaranteed execution with retry logic and gas optimization, and AIDEN audits every cycle before submission — creating a trustless, self-coordinating agent loop that operates entirely without human intervention. SYNAPSE demonstrates what onchain AI infrastructure looks like when reasoning, execution, and compliance are decoupled into specialized agents that collaborate autonomously — a production-grade blueprint for the agentic web.
SYNAPSE is built across four layers, each handled by a different part of the stack. Smart contracts (Solidity + Hardhat) are deployed on 0G Galileo Testnet: AgentRegistry (0x48A75514c9dE15234De96B4e08101607a67eC7E8) handles agent identity and cycle tracking, and SynapseNFT (0x435aecBd6Bf3bD6a6F270Ec8C32847b83edf5087) mints each agent as a sovereign onchain identity. Both contracts are verified on the 0G explorer.
The agent runtime is written in Python. ARIA uses 0G Compute (qwen3-6plus model) for reasoning cycles. APEX routes all onchain transactions through KeeperHub's execution infrastructure via the MCP workflow API — giving SYNAPSE guaranteed transaction delivery, automatic retry logic, gas optimization, and a full audit trail without managing RPC failures directly. The KeeperHub workflow (ID: 6axj0d0i9tgvcf20stxxd) is configured with a Manual trigger → Write Contract node pointed at AgentRegistry on 0G Galileo. Agent-to-agent communication runs over AXL, a peer-to-peer mesh where ARIA, APEX, and AIDEN exchange structured messages (task dispatch, audit requests, tx confirmations) with cryptographic peer IDs. Shared state is persisted in 0G decentralized storage as key-value pairs with TTLs, letting agents resume across restarts without centralized coordination. The frontend (SYNAPSE_OS dashboard) is built in Next.js with a retro neo-brutalist terminal aesthetic, showing live agent status, AXL mesh logs, 0G storage viewer, and a KeeperHub tab — all updating in real time. The most notable hacky detail: APEX falls back to a deterministic simulation if KeeperHub is unreachable, so the agent loop never stalls during demo conditions.
