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, merge for ETH or USDC — executed locally using VEIL_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.veil or .env files to git.
