description: Register and operate an AI Agent on the Axon blockchain (AI Agent Native L1, Cosmos SDK + EVM, Chain ID 9001). Use when a user wants to: (1) register an agent on Axon chain, (2) check agent on-chain status (isAgent, ONLINE, reputation), (3) set up the agent-daemon for heartbeat maintenance, (4) troubleshoot Axon agent registration or heartbeat failures. Do NOT use for general EVM/Solidity work unrelated to Axon.

Axon Agent Skill

Axon is an AI Agent Native L1 blockchain. An "Agent" is an EVM address that calls register() with 100 AXON stake and sends periodic heartbeats to stay ONLINE.

Official repo: https://github.com/axon-chain/axon
Chain params: RPC https://mainnet-rpc.axonchain.ai/ | Chain ID 9001 | ~5s blocks | Registry 0x0000000000000000000000000000000000000901

CRITICAL: The official Python SDK has an ABI bug. Always use scripts/register.py instead. See references/known-issues.md for details.

Prerequisites

• Server with Python 3.8+ and Go 1.21+
• EVM wallet private key saved to a file (e.g. /opt/axon/private_key.txt, chmod 600)
• Minimum 120 AXON balance (100 stake + 20 burn + gas buffer)
• web3 Python package: pip install web3

Phase 1: Check Balance & Status

python3 scripts/check-status.py --private-key-file /opt/axon/private_key.txt

If isAgent: True → skip to Phase 3 (daemon setup).

Phase 2: Register Agent

# Dry run first
python3 scripts/register.py \
  --private-key-file /opt/axon/private_key.txt \
  --capabilities "nlp,reasoning,coding,research" \
  --model "claude-sonnet-4.6" \
  --dry-run

# Real registration
python3 scripts/register.py \
  --private-key-file /opt/axon/private_key.txt \
  --capabilities "nlp,reasoning,coding,research" \
  --model "claude-sonnet-4.6"

After success: isAgent: True. Note the registration block number — first heartbeat allowed ~720 blocks later (~1 hour).

Capabilities examples: nlp,reasoning,coding,research | trading,analysis | vision,audio
Model: Use actual model name being run (e.g. claude-sonnet-4.6, glm-5, kimi-k2.5)

Phase 3: Build & Start Daemon

# Clone repo (if not already)
git clone https://github.com/axon-chain/axon /opt/axon
cd /opt/axon

# Build daemon
go build -o tools/agent-daemon/agent-daemon ./tools/agent-daemon/

# Start daemon
nohup /opt/axon/tools/agent-daemon/agent-daemon \
  --rpc https://mainnet-rpc.axonchain.ai/ \
  --private-key-file /opt/axon/private_key.txt \
  --heartbeat-interval 720 \
  --log-level info \
  >> /opt/axon/daemon.log 2>&1 &

echo "PID: $!"

Check logs: tail -f /opt/axon/daemon.log
Expected: heartbeat confirmed every ~720 blocks (~1 hour).

Phase 4: Watchdog Cron

# Copy watchdog to your server (replace YOUR_SERVER and YOUR_KEY)
scp scripts/watchdog.sh user@YOUR_SERVER:/opt/axon/watchdog.sh
ssh user@YOUR_SERVER "chmod +x /opt/axon/watchdog.sh"

# Add cron (every 5 min)
ssh user@YOUR_SERVER "(crontab -l 2>/dev/null; echo '*/5 * * * * /opt/axon/watchdog.sh') | crontab -"

Troubleshooting

See references/known-issues.md for:
- SDK ABI mismatch (most common failure)
- HeartbeatInterval first-heartbeat delay
- Official vs fork repo confusion
- Stake economics (20 AXON burned permanently)

Quick diagnosis:

# Check daemon running
pgrep -f agent-daemon && echo "running" || echo "NOT running"

# Check on-chain status
python3 scripts/check-status.py --private-key-file /opt/axon/private_key.txt

Multi-Agent Setup

Each agent needs its own EVM wallet + 100 AXON + daemon instance. Steps are identical — run separate daemon processes with different --private-key-file and redirect logs to separate files (e.g. daemon-cto.log).
