bankr dev - portfolio is a Claude Code skill that fetches multi-chain wallet balances, token positions, and portfolio valuations from the Bankr API for developers building dashboards, risk engines, or treasury reporting
About
bankr dev - portfolio is a Claude Code skill (version 1.0.0) from bankrbot/claude-plugins for querying crypto portfolio data through the Bankr API via natural-language prompts. It supports ten query patterns including total portfolio, chain-specific balances, token holdings, and cross-chain token views across Base, Polygon, Ethereum, Unichain, and Solana. TypeScript usage calls execute() from bankr-client with prompts like 'Show my portfolio' or 'How much ETH do I have?'. Reach for this skill when implementing portfolio dashboards or balance checks—not for executing trades (use bankr-token-trading) or API key security setup (use bankr-safety).
- Balance and position endpoints
- Treasury snapshot queries
- Dashboard data plumbing
- Risk and reporting inputs
- Pairs with API basics skill

How do you fetch multi-chain crypto portfolio data?
Fetch wallet balances, token positions, and portfolio snapshots from Bankr to power dashboards, risk engines, billing, or treasury reporting in backend services.
Who is it for?
Backend developers integrating Bankr into dashboards, billing, risk engines, or treasury tools that need multi-chain balance and holdings queries.
Skip if: Skip bankr dev - portfolio when implementing token trades, NFT operations, or API key security configuration—use bankr-token-trading, bankr-nft-operations, or bankr-safety skills instead.
When should I use this skill?
User asks to build portfolio dashboards, check wallet balances, list crypto holdings, or add multi-chain portfolio views with Bankr.
What you get
Portfolio snapshots with balances, token positions, and valuations across supported chains from Bankr API responses.
- Portfolio query integration code
- Multi-chain balance responses
- Holdings snapshot handlers
By the numbers
- Skill version 1.0.0
- Ten documented portfolio query operation patterns
- Five supported blockchains: Base, Polygon, Ethereum, Unichain, Solana

Safety & Access Control
Comprehensive safety guidance for using the Bankr API and CLI.
API Key Types
Bankr uses a single key format (bk_...) with capability flags:
| Flag | Controls | Default |
|---|---|---|
agentApiEnabled | /agent/* endpoints | false |
llmGatewayEnabled | LLM Gateway at llm.bankr.bot | false |
readOnly | Restricts agent to read-only tools | false |
Manage flags at bankr.bot/api.
Read-Only API Keys
When readOnly: true, all write tools are filtered from the agent session:
Allowed: Balances, prices, analytics, portfolio, research Blocked: Swaps, transfers, NFT purchases, staking, orders, token launches, leverage, Polymarket bets, claims
The /agent/sign and /agent/submit endpoints return 403 for read-only keys.
IP Whitelisting
Set allowedIps on your API key to restrict usage to specific IPs. Requests from non-whitelisted IPs are rejected with 403.
- Empty array = all IPs allowed (default)
- Non-empty array = only listed IPs can use the key
Dedicated Agent Wallet
When building autonomous agents, create a separate Bankr account rather than using your personal wallet:
- Limited exposure — compromised key only exposes agent wallet funds
- Clear accounting — agent transactions isolated from personal activity
- Independent controls — apply stricter access controls without affecting personal use
- Easy revocation — disable agent account without disrupting primary wallet
Recommended Funding
| Chain | Gas Buffer | Trading Capital |
|---|---|---|
| Base | 0.01-0.05 ETH | As needed |
| Polygon | 5-10 MATIC | As needed |
| Ethereum | 0.05-0.1 ETH | As needed |
| Solana | 0.1-0.5 SOL | As needed |
Rate Limits
| Tier | Daily Limit |
|---|---|
| Standard | 100 messages/day |
| Bankr Club | 1,000 messages/day |
| Custom | Set per API key |
Reset window is 24 hours from first message (rolling), not midnight.
Key Management
- Store keys in environment variables (
BANKR_API_KEY,BANKR_LLM_KEY), never in source code - Add
~/.bankr/and.envto.gitignore - Rotate keys periodically at bankr.bot/api
- Revoke immediately if compromised
- Use separate keys for Agent API vs LLM Gateway if needed
Transaction Safety
- Test first — small amounts on Base/Polygon before scaling
- Verify recipients — double-check addresses before transfers
- Gas buffer — keep enough native tokens for gas
- Immediate execution —
/agent/submitexecutes with no confirmation prompt - Understand calldata — verify trusted source for arbitrary transactions
Pre-Deployment Checklist
- Use a dedicated agent wallet, not your personal account
- Fund with limited amounts appropriate to purpose
- Set read-only if agent only queries data
- Configure IP whitelisting for server-side agents
- Store keys in environment variables
- Test with small amounts first
- Implement error handling for rate limits (429) and access control (403)
