Pouls

Pouls (French for "pulse") is a client-side dashboard that tracks the live pulse of your crypto net worth — DeFi positions, staking, and plain wallet holdings — across Solana, Ethereum & other EVM chains, Tron, Cardano, Cosmos, and Polkadot, from nothing but public wallet addresses.

No backend. No API keys. No private keys or seed phrases — ever. Everything runs in your browser against public, CORS-enabled APIs and on-chain RPCs, and your addresses never leave localStorage.

⚠️ Read-only portfolio tracker, not financial advice. Values are best-effort snapshots from public data and may lag or differ from the protocols' own UIs.

Features

• One address in, full picture out. Paste a Solana, EVM (0x…), Tron (T…), Cardano (addr1…/stake1…), Cosmos (cosmos1…), or Polkadot address — Pouls detects the chain from the address format and fans out to every relevant source.
• Multiple wallets & portfolios. Group several addresses into named portfolios and switch between them. Adding a wallet only fetches that wallet, then re-aggregates.
• Net-worth chart with 1M / 3M / 6M / 1Y ranges and PnL since your last investment, reconstructed from price history (no historical balance API needed).
• Allocation donut by protocol, and All / DeFi / Assets tabs with collapsible per-protocol cards showing each position's value, APY, earned yield, cost basis, and PnL.
• 9 display currencies (USD, EUR, GBP, JPY, CNY, CAD, AUD, CHF, ZAR) and a dark / light theme.

EVM wallet	6 EVM chains	Native coin + major ERC-20s	On-chain Multicall3 (viem) + DefiLlama prices
Tron	Tron	TRX + major TRC-20s, staking	TronGrid + Binance prices
Cardano	Cardano	ADA (UTxO across the stake account + staking rewards)	pool.pm + Binance price
Cosmos Hub	Cosmos	ATOM balance, staked, rewards	cosmos.directory LCD + Binance price
Polkadot	Polkadot	DOT balance + staked	Public JSON-RPC (relay chain + Asset Hub)

Prices come from Binance and DefiLlama; fiat conversion from open.er-api.com. On-chain reads use viem's fallback() transport across several public RPCs, so a single flaky endpoint won't break a read — if all RPCs for a chain fail, the UI shows a warning rather than a misleading $0.

To keep a single refresh from re-fetching the same address-independent data once per wallet, registry and price responses are de-duplicated and briefly cached (see src/lib/http.js).

Run

npm install
npm run dev       # http://localhost:5173
npm run build     # production bundle in dist/
npm run preview   # serve the built bundle locally

Enter one or more wallet addresses. They're saved to localStorage and reloaded on your next visit; use Refresh to re-fetch. The build in dist/ is fully static — host it anywhere (GitHub Pages, Netlify, an S3 bucket) with no server.

Privacy & security

• Pouls only ever takes public addresses. It has no field for, and no use for, private keys or seed phrases.
• There is no backend: requests go straight from your browser to public APIs and RPCs. Those providers see the addresses you query (the same as any block explorer) but nothing else.
• Portfolios, addresses, and the net-worth history are stored only in your browser's localStorage. Clear it to wipe everything.

Extending

• More EVM chains for Beefy: add an entry to CHAINS in src/lib/beefy.js — any Beefy-supported chain with a Multicall3 deployment and a public RPC works.
• More wallet chains: add a reader in src/lib/, register it in ROUTES in src/App.vue, and add an address matcher to detectAddressType in src/lib/format.js.
