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:

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.

npm install -g viem

Quick Start

# 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

Supported Chains

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:

./scripts/verify-primary.sh 0xYourAddress base

Output:

✅ Reverse record: 0x1234... → myname.eth
✅ Forward resolution: myname.eth → 0x1234...
🎉 PRIMARY NAME VERIFIED: myname.eth

Setting Avatars

# 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).
