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: Transaction Signing This skill requires a way to sign and submit transactions. It looks for the bankr skill which provides wallet functionality via the Bankr API. If you don't have bankr installed: Install from: https://github.com/BankrBot/openclaw-skills (bankr skill) Or modify the scripts to use your own transaction submission method The scripts call bankr.sh with a prompt like: Submit this transaction: {"to": "0x...", "data": "0x...", "value": "0", "chainId": 8453} You can replace the find_bankr() function in each script with your own wallet/signer. 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 Chain Reverse Registrar Base 0x0000000000D8e504002cC26E3Ec46D81971C1664 Arbitrum 0x0000000000D8e504002cC26E3Ec46D81971C1664 Optimism 0x0000000000D8e504002cC26E3Ec46D81971C1664 Ethereum 0x283F227c4Bd38ecE252C4Ae7ECE650B0e913f1f9 Prerequisites Own or control an ENS name - The name must be registered Forward resolution configured - The name must resolve to your address Native tokens for gas - ETH on the target chain How It Works Checks forward resolution exists (name → address) Warns if chain-specific address is not set Encodes setName(string) calldata Submits transaction to the Reverse Registrar 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). Troubleshooting Issue Solution "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.sh not found" Install bankr skill or modify scripts to use your signer "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 Customization Using a Different Wallet/Signer Replace the find_bankr() function in the scripts:

Example: use cast (foundry) instead

send_tx ( ) { local to = " $1 " data = " $2 " chain_id = " $3 " cast send " $to " --data " $data " --rpc-url "https://..." --private-key " $PRIVATE_KEY " } Links ENS Docs: https://docs.ens.domains/web/reverse ENS App: https://app.ens.domains Primary Names UI: https://primary.ens.domains Bankr Skill: https://github.com/BankrBot/openclaw-skills
