Base Sepolia Testnet

Base Sepolia is the current public testnet for Dome shielded ETH. Hosted infrastructure (when running):

API / indexer: https://api.getdome.app
Circuits: https://circuits.getdome.app

Deploy contracts

export ALCHEMY_KEY=...
export PRIVATE_KEY=0x...
bash scripts/base/deploy-sepolia.sh

Writes .dome-local/base-sepolia-deploy.json. Fund the deployer/relayer address with Base Sepolia ETH.

Or use the setup script (deploy if funded):

# Configure .dome-local/sepolia.env first
bash scripts/testnet/setup-sepolia.sh

Backend configuration

Copy dome-backend/.env.sepolia.example to .env on your host:

Variable	Notes
`DOME_DEPLOY_FILE`	`.dome-local/base-sepolia-deploy.json`
`DOME_DEV_FAUCET`	`false` — no faucet on public networks
`DOME_RELAYER_PRIVATE_KEY`	Dedicated key; never the Hardhat default
`DOME_DATABASE_URL`	Postgres recommended for production
`DOME_RELAYER_SECRET`	Required for public relayer endpoint

Start:

cd dome-backend
npm install
npm start

For tunnel + circuits + backend together:

bash scripts/cloudflare/up-sepolia.sh

See Cloudflare Tunnel and Backend & Indexer.

SDK smoke test

No web UI required:

cd dome-sdk-evm
npm run build
export PRIVATE_KEY=0x...
export DOME_EVM_INDEXER_URL=https://api.getdome.app
export DOME_ETH_POOL_ADDRESS=0x...   # from deploy manifest
export DOME_FEE_RECIPIENT_ADDRESS=0x...
export DOME_BASE_RPC=https://base-sepolia.g.alchemy.com/v2/YOUR_KEY
export DOME_CHAIN_ID=84532
export DOME_CIRCUIT_KEY_BASE_PATH=https://circuits.getdome.app/transaction
node scripts/smoke-sepolia.mjs balance
node scripts/smoke-sepolia.mjs deposit 0.001
node scripts/smoke-sepolia.mjs withdraw 0.0006

Relayer balance

The relayer pays gas for withdraws. Check and fund as needed:

bash scripts/testnet/check-relayer-balance.sh

Fund via the Alchemy faucet if balance drops below ~0.05 ETH.

Circuits

Browsers load Groth16 artifacts over HTTPS. See Circuit Hosting.

Client env (summary)
