modbender Warren - On-Chain Website Deployment
Deploy websites permanently on MegaETH blockchain. Content is stored on-chain using SSTORE2 and cannot be deleted.
Network: MegaETH Testnet (Chain ID: 6343)
RPC: https://carrot.megaeth.com/rpc
Explorer: https://megaeth-testnet-v2.blockscout.com
Setup (One Time)
cd {baseDir}
bash setup.sh
This installs ethers.js, the only dependency.
Prerequisites
1. Create a Wallet
node -e "const w = require('ethers').Wallet.createRandom(); console.log('Address:', w.address); console.log('Private Key:', w.privateKey)"
Set the private key:
export PRIVATE_KEY=0xYourPrivateKey
2. Get Testnet ETH
Visit https://docs.megaeth.com/faucet and enter your wallet address. This requires a captcha. You need ~0.1 ETH for multiple deployments.
Check balance:
node -e "const{ethers}=require('ethers');new ethers.JsonRpcProvider('https://carrot.megaeth.com/rpc',6343).getBalance('$YOUR_ADDRESS').then(b=>console.log(ethers.formatEther(b),'ETH'))"
3. Genesis Key NFT
The deploy script automatically mints a free Genesis Key NFT if you don't have one. No manual action needed.
Deploy
Deploy HTML string
cd {baseDir}
PRIVATE_KEY=0x... node deploy.js \
--html "<html><body><h1>Hello Warren!</h1></body></html>" \
--name "My First Site"
Deploy HTML file
PRIVATE_KEY=0x... node deploy.js \
--file ./my-site.html \
--name "My Website"
Deploy via stdin
echo "<h1>Hello</h1>" | PRIVATE_KEY=0x... node deploy.js --name "Piped"

Output
{
"tokenId": 102,
"rootChunk": "0x019E5E...",
"depth": 0,
"url": "https://megawarren.xyz/loader.html?registry=0x7bb4233017CFd4f938C61d1dCeEF4eBE837b05F9&id=102"
}
Stress Test Workflows
Deploy multiple random sites
cd {baseDir}
for i in $(seq 1 10); do
HTML="<html><body><h1>Stress Test #$i</h1><p>$(date)</p></body></html>"
PRIVATE_KEY=0x... node deploy.js --html "$HTML" --name "Stress Test $i"
sleep 2
done
Deploy a larger site (~50KB)
python3 -c "
html = '<html><body>'
for i in range(1000):
html += f'<p>Paragraph {i}: Lorem ipsum dolor sit amet</p>'
html += '</body></html>'
print(html)
" > large-site.html
PRIVATE_KEY=0x... node deploy.js --file large-site.html --name "Large Test"

Troubleshooting
"No ETH" → Get from https://docs.megaeth.com/faucet (captcha required)
"RPC rate limit" → Built-in retry. Add sleep 5 between batch deploys.
"Insufficient funds" → ~0.001-0.02 ETH per deploy. Get more from faucet.
Site doesn't load → Wait 10-30s. Check URL has correct registry and token ID.
Notes
- Testnet only — may reset
- Max 500KB per deployment
- Content is immutable once on-chain
- You pay gas from your own wallet
- Genesis Key NFT auto-mints (free)
