Agent skill
veil
Privacy and shielded transactions on Base via Veil Cash (veil.cash). Deposit ETH or USDC into private pools, withdraw/transfer privately using ZK proofs. Manage Veil keypairs, check private/queue balances across all pools, and submit deposits via Bankr. Use when the user wants anonymous or private transactions, shielded transfers, or ZK-based privacy on Base.

Veil
This skill wraps the @veil-cash/sdk CLI to make Veil operations agent-friendly.
Supported Assets
| Asset | Decimals | Description |
|---|---|---|
| ETH | 18 | Native ETH (via WETH) |
| USDC | 6 | USDC on Base |
What it does
- Key management: generate and store a Veil keypair locally
- Status check: verify configuration, registration, and relay health
- Balances:
veil balance(queue + private) — supports--pool eth|usdc - Deposits via Bankr: build Bankr-compatible unsigned transactions and ask Bankr to sign & submit (handles ERC20 approve + deposit for USDC)
- Private actions:
withdraw,transfer,mergefor ETH or USDC — executed locally usingVEIL_KEY(ZK/proof flow)
File locations (recommended)
- Veil keys:
~/.clawdbot/skills/veil/.env.veil(chmod 600) - Bankr API key:
~/.clawdbot/skills/bankr/config.json
Quick start
1) Install the Veil SDK
Option A: Global npm install (recommended)
npm install -g @veil-cash/sdk
Option B: Clone from GitHub
mkdir -p ~/.openclaw/workspace/repos
cd ~/.openclaw/workspace/repos
git clone https://github.com/veildotcash/veildotcash-sdk.git
cd veildotcash-sdk
npm ci && npm run build
2) Configure Base RPC (recommended)
Veil queries a lot of blockchain data (UTXOs, merkle proofs, etc.), so public RPCs will likely hit rate limits. A dedicated RPC from Alchemy, Infura, or similar is recommended.
Put RPC_URL=... in one of these:
~/.clawdbot/skills/veil/.env(preferred)- or the SDK repo
.env(less ideal)
Example:
mkdir -p ~/.clawdbot/skills/veil
cat > ~/.clawdbot/skills/veil/.env << 'EOF'
RPC_URL=https://base-mainnet.g.alchemy.com/v2/YOUR_KEY
EOF
chmod 600 ~/.clawdbot/skills/veil/.env
3) Make scripts executable
chmod +x scripts/*.sh
4) Generate your Veil keypair
scripts/veil-init.sh
scripts/veil-keypair.sh
5) Check your setup
scripts/veil-status.sh
6) Find your Bankr Base address
scripts/veil-bankr-prompt.sh "What is my Base wallet address? Respond with just the address."
7) Check balances
# ETH pool (default)
scripts/veil-balance.sh --address 0xYOUR_BANKR_ADDRESS
# USDC pool
scripts/veil-balance.sh --address 0xYOUR_BANKR_ADDRESS --pool usdc
8) Deposit via Bankr (sign & submit)
# Deposit ETH
scripts/veil-deposit-via-bankr.sh ETH 0.011 --address 0xYOUR_BANKR_ADDRESS
# Deposit USDC (auto-handles approve + deposit)
scripts/veil-deposit-via-bankr.sh USDC 100 --address 0xYOUR_BANKR_ADDRESS
9) Withdraw (private to public)
scripts/veil-withdraw.sh ETH 0.007 0xYOUR_BANKR_ADDRESS
scripts/veil-withdraw.sh USDC 50 0xRECIPIENT
10) Transfer privately
scripts/veil-transfer.sh ETH 0.01 0xRECIPIENT
scripts/veil-transfer.sh USDC 25 0xRECIPIENT
11) Merge UTXOs
scripts/veil-merge.sh ETH 0.1
scripts/veil-merge.sh USDC 100

Notes
- For Bankr signing, this skill uses Bankr's Agent API via your local
~/.clawdbot/skills/bankr/config.json. - For USDC deposits via Bankr, the skill automatically submits the ERC20 approval transaction first, then the deposit transaction.
- For privacy safety: never commit
.env.veilor.envfiles to git.
