Set your primary ENS name on Base and other L2s. Use when user wants to set their ENS name, configure reverse resolution, set primary name, or make their address resolve to an ENS name. Supports Base, Arbitrum, Optimism, and Ethereum mainnet.

ENS Primary Name

Set your primary ENS name on Base and other L2 chains via the ENS Reverse Registrar.
A primary name creates a bi-directional link:
  • Forward: 
    name.eth
    → 
    0x1234...
    (set in ENS resolver)
  • Reverse: 
    0x1234...
    → 
    name.eth
    (set via this skill)

Requirements

Required: Bankr CLI

This skill requires the Bankr CLI for transaction signing:
bash
bun install -g @bankr/cli
bankr login
The scripts use 
bankr prompt
to submit transactions like:
Submit this transaction: {"to": "0x...", "data": "0x...", "value": "0", "chainId": 8453}

Required: Node.js

Scripts use Node.js with 
viem
for ENS namehash calculation and ABI encoding.
bash
npm install -g viem

Quick Start

bash
# Set primary name on Base
./scripts/set-primary.sh myname.eth

# Set on specific chain
./scripts/set-primary.sh myname.eth arbitrum

# Verify primary name is set
./scripts/verify-primary.sh 0x1234... base

# Set avatar (L1 only)
./scripts/set-avatar.sh myname.eth https://example.com/avatar.png

Prerequisites

  1. Own or control an ENS name - The name must be registered
  2. Forward resolution configured - The name must resolve to your address
  3. Native tokens for gas - ETH on the target chain

How It Works

  1. Checks forward resolution exists (name → address)
  2. Warns if chain-specific address is not set
  3. Encodes 
    setName(string)
    calldata
  4. Submits transaction to the Reverse Registrar
  5. Verifies the primary name is correctly set

Verification

The skill automatically verifies after setting. You can also verify manually:
bash
./scripts/verify-primary.sh 0xYourAddress base
Output:
✅ Reverse record: 0x1234... → myname.eth
✅ Forward resolution: myname.eth → 0x1234...
🎉 PRIMARY NAME VERIFIED: myname.eth

Setting Avatars

bash
# Set avatar (requires L1 transaction + ETH for gas)
./scripts/set-avatar.sh myname.eth https://example.com/avatar.png
Supported avatar formats:
  • HTTPS: 
    https://example.com/image.png
  • IPFS: 
    ipfs://QmHash
  • NFT: 
    eip155:1/erc721:0xbc4ca.../1234
Note: Avatars are text records stored on Ethereum mainnet. The script automatically looks up the resolver for your ENS name (works with both public and custom resolvers).

Troubleshooting

IssueSolution
"Transaction reverted"Ensure the ENS name resolves to your address
"Name not showing"Forward resolution may not be set for that chain's cointype
"Not authorized"You must call from the address the name resolves to
"Bankr CLI not found"Install with 
bun install -g @bankr/cli && bankr login
"Chain-specific address not set"Set the address for the target chain via app.ens.domains
"Could not find resolver"Ensure the ENS name exists and has a resolver set
