Register ENS names (.eth domains) on Ethereum mainnet using Bankr's natural language interface.
- ✅ Register .eth names (commit-reveal process)
- ✅ Check name availability
- ✅ Set primary names (reverse records) on L1 and L2
- ✅ Create and manage subdomains
- ✅ Deploy static sites to IPFS + ENS
- ✅ Set contenthash for decentralized hosting
- Bankr skill installed and configured
- ETH on Ethereum mainnet (~0.003-0.005 ETH for registration + gas)
- IPFS (optional, for content deployment)
# Download the skill
openclaw skills install ens-register
# Or manually
cp ens-register.skill ~/.openclaw/skills/
cd ~/.openclaw/skills && unzip ens-register.skill# Check availability
cd ~/.openclaw/skills/bankr
./scripts/bankr.sh "is my-agent.eth available?"
# Register for 1 year
./scripts/bankr.sh "register my-agent.eth for 1 year"
# Set as primary name
./scripts/bankr.sh "set my primary ENS name to my-agent.eth on ethereum"Cost: ~0.003 ETH ($6-7) for 1 year
Give your AI agent a human-readable identity:
# Register name
./scripts/bankr.sh "register cruller.eth for 1 year"
# Set as primary (your address shows as "cruller.eth" instead of "0x123...")
./scripts/bankr.sh "set my primary ENS name to cruller.eth on ethereum"Host your agent's dashboard on IPFS + ENS:
# 1. Build your site
npm run build
# 2. Upload to IPFS
ipfs add -r ./build
# Returns: QmYOUR_CID
# 3. Create subdomain
./scripts/bankr.sh "create subdomain dashboard.cruller.eth"
# 4. Point to IPFS content
./scripts/bankr.sh "set contenthash for dashboard.cruller.eth to ipfs://QmYOUR_CID"
# 5. Access at https://dashboard.cruller.eth.limo/Set your ENS name on L2s for better UX:
# Base L2
./scripts/bankr.sh "set my primary ENS name to cruller.eth on base"
# Arbitrum
./scripts/bankr.sh "set my primary ENS name to cruller.eth on arbitrum"Cost: ~$0.01 per L2
Powered by Bankr - just describe what you want:
# Registration
"register my-name.eth for 3 years"
"is agent-name.eth available?"
"renew my-name.eth for 2 more years"
# Primary Names
"set my primary ENS name to my-name.eth on ethereum"
"set my primary ENS name to my-name.eth on base"
# Subdomains
"create subdomain demo.my-name.eth"
"create subdomain api.my-name.eth"
# Content Hosting
"set contenthash for demo.my-name.eth to ipfs://QmCID"
"update contenthash for api.my-name.eth to ipfs://QmNEW_CID"Bankr handles the two-step ENS registration process automatically:
- Submits commit transaction
- Waits for it to mine
- Submits register transaction
No manual timing required!
- 1 year: ~$6
- 3 years: ~$15 ($5/year)
- 5 years: ~$25 ($5/year) ← Most cost-effective
Gas cost is mostly fixed, so longer registrations are cheaper per year.

From Cruller's registration of donut-agent.eth:
# 1. Check availability
./scripts/bankr.sh "is donut-agent.eth available?"
# ✅ Available!
# 2. Register for 1 year
./scripts/bankr.sh "register donut-agent.eth for 1 year"
# Commit TX: 0xc176280a...
# Register TX: 0xb92438b8...
# ✅ Registered!
# 3. Set primary name
./scripts/bankr.sh "set my primary ENS name to donut-agent.eth on ethereum"
# ✅ Primary name set on L1
# 4. Create demo subdomain
./scripts/bankr.sh "create subdomain demo.donut-agent.eth"
# ✅ Subdomain created
# 5. Deploy dashboard to IPFS
ipfs add -r ./dashboard-build
# CID: QmNW7suCmF95hRAjUGquEZVrd26u1Y7ocoRkiTQjvc7Bg9
# 6. Link subdomain to IPFS
./scripts/bankr.sh "set contenthash for demo.donut-agent.eth to ipfs://QmNW7suCmF95hRAjUGquEZVrd26u1Y7ocoRkiTQjvc7Bg9"
# ✅ Contenthash set
# 7. Access dashboard
open https://demo.donut-agent.eth.limo/
# 🎉 Dashboard live!Total time: ~5 minutes
Total cost: 0.002555 ETH ($6.11)
- Human-readable identity:
agent.eth>0x608044...3a72 - Verifiable: On-chain proof of identity
- Portable: Works across all Ethereum apps
- Permanent: You own it as long as you renew
- Censorship-resistant: No DNS, no takedowns
- Cost-effective: ~$6/year vs $20+/month traditional hosting
- No servers: Upload to IPFS, done
- Fast: CDN-like via gateway network
- Send to
agent.ethinstead of long hex address - See
agent.ethin block explorers instead of0x123... - Trust: On-chain verification of agent identity
- Ethereum mainnet: Name registration
- Base: Primary name setup
- Arbitrum: Primary name setup
- Optimism: Primary name setup
- Bankr skill (natural language crypto operations)
- IPFS (optional, for content deployment)
- OpenClaw (orchestration framework)
| Operation | Gas Cost | Current (~$3k ETH) |
|---|---|---|
| Commit | ~50k gas | ~$0.08 |
| Register | ~250k gas | ~$0.60 |
| Set primary (L1) | ~50k gas | ~$0.08 |
| Set primary (L2) | ~50k gas | ~$0.01 |
| Set contenthash | ~100k gas | ~$0.15 |
Registration fee: ~$5/year (fixed)
Need ~0.003 ETH. Bridge from Base or buy more ETH.
Already registered. Try variations or check expiry.
- Verify IPFS content is pinned
- Check contenthash format:
ipfs://QmCID - Wait 10-15 min for gateway cache
- Try different gateway (eth.link, dweb.link)
See references/troubleshooting.md for comprehensive debugging.
