# 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)

## 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
```

## Supported Chains

| Chain | Reverse Registrar |
|-------|-------------------|
| Base | `0x0000000000D8e504002cC26E3Ec46D81971C1664` |
| Arbitrum | `0x0000000000D8e504002cC26E3Ec46D81971C1664` |
| Optimism | `0x0000000000D8e504002cC26E3Ec46D81971C1664` |
| Ethereum | `0x283F227c4Bd38ecE252C4Ae7ECE650B0e913f1f9` |

## Prerequisites

1. **Own or control an ENS name** - The name must be registered
2. **Forward resolution configured** - The name must resolve to your address on the target chain
3. **Bankr wallet** - Used to sign and submit the transaction

## How It Works

1. Encodes `setName(string)` calldata with your ENS name
2. Submits transaction to the Reverse Registrar via Bankr
3. After confirmation, apps will show your ENS name instead of address

## Troubleshooting

| Issue | Solution |
|-------|----------|
| "Transaction reverted" | Ensure the ENS name resolves to your address on that chain |
| "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 |

## Manual Process

If the script fails, call `setName(string)` on the Reverse Registrar:

```solidity
// Function selector: 0xc47f0027
setName("yourname.eth")
```

## Setting Avatars

```bash
# Set avatar (requires L1 transaction)
./scripts/set-avatar.sh myname.eth https://example.com/avatar.png

# Supported 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, so this requires ETH for gas on L1.
