BStocks

A self-custodial interface for Coinbase Tokenized Stocks on Base (the B20 standard). Live prices and charts, best-route trading across several DEX aggregators, baskets and recurring plans, yield discovery, gifting stock to a Basename or a whole group at once, and a fenced AI assistant — all without holding keys or funds.

Coinbase Tokenized Stocks are available only to eligible persons outside the United States. BStocks is an independent interface built on Base, not an official Base or Coinbase product, and does not provide investment advice.

What it does

Area	Highlights
Markets	13 stocks with live DEX price, Chainlink reference and freshness, candles and volume, a Live / Thin / Very thin / No pool / Not issued status, single Buy action
Trade	Every quote asks KyberSwap, Velora, the Uniswap Trading API, Aerodrome directly, CoW Protocol and, when enabled, 0x and OKX; you pick auto (best net output) or a provider. Pay with USDC or ETH. Exact approvals, simulation before signing, atomic batches on Base Account. CoW orders are signed, not sent: solvers pay the gas. Limit orders at your own price, cancellable any time
Strategies	Build baskets (sliders, templates, guided AI drafts with live market context), community baskets with votes and clones, and auto-invest: a stock or a basket bought on a schedule by the AutoInvest contract — amount, cadence, routes and minimum output enforced onchain, cancel or revoke any time — or, if you prefer, a plan that waits for your confirmation per run
Earn	Idle USDC into Morpho vaults, Aave V3 and Compound v3 from the app; stock pools, LP positions and lending venues discovered at runtime, never hardcoded
Portfolio	Value (stocks + USDC + Earn + LP), allocation, history, profit and loss, rebalance against a template or your own saved target (one drift measure for the banner, the table and the trades), verified activity, daily AI summary and badges
Send & gift	To a Basename or address with the recipient's profile shown first, or a claim link for someone without a wallet: the stock waits in an ownerless escrow, they claim it with a passkey Base Account and the gas is sponsored. Public receipt pages to share
Gift pools	One deposit, many equal shares of one stock or a package of several: a share link, a public directory or steps to finish first. Onchain steps (a Basename, a holding, a verified purchase) are read from Base; X steps are recorded as the claimant's own confirmation and labelled that way. Close a pool any time — or lock it so you cannot — and the unclaimed remainder comes home
News	Headlines per stock and market-wide, a Base & Coinbase feed that follows tokenized-stock listings and venues, and one shared AI brief every six hours that reads ~60 headlines and leads with that ecosystem; the same brief and headlines ground the basket and plan drafts, which come with a "why this mix" commentary
Compliance	Eligibility notice for restricted regions (attest or block mode), issuer policies and pauses read before every action
Stats	/stats: trades, volume, wallets, gifts, pools, Earn and plan runs, every figure verified against its receipt on Base; a six-figure summary and an anonymous public feed on the home page
Status	Live, smoothed checks of every dependency at /status

The narrative and FAQ live in the app at /how-it-works. The technical reference (contracts, data sources, providers, environment, routes) is docs/HOW_IT_WORKS.md; the backlog is docs/ROADMAP.md.

Also in the box

• Installable: a web app manifest with maskable icons and shortcuts; add BStocks to a phone or desktop and it opens in its own window. No service worker, so no stale prices from a cache.
• Printable gift cards: every gift link, bulk link and pool link prints as a QR card (four to an A4 sheet), drawn in the browser — the link never reaches a server.
• Public feed: the latest verified transactions, with no wallet named, on Home and on Activity for visitors without a wallet; the same shared-cached object as the counters and /stats.
• Heatmap view: Markets can be read as tiles instead of a list, each stock coloured by its 24h move with the three deepest markets doubled; the choice is remembered.
• Benchmark: the equal-weight index of the listed stocks runs dashed behind the portfolio's value history, one shared-cached series per window.
• Gift a basket: any template or basket becomes a one-share package, claimable with a link, from the stocks you hold.
• Statistics that stay cheap: finished days are rolled up once and stored; /stats reads the recent days and the rollups, so it costs the same at ten thousand records as at a hundred.
• An integrator fee, off by default: set a rate and a recipient and KyberSwap, CoW and 0x routes carry it, shown on the quote and summed on /stats.
• Return to target on a schedule: a buy-only manual plan from the Rebalance tab, legs computed from live holdings on each run, confirmed in the wallet, never automatic, never a sell.

Quick start

pnpm install

pnpm dev

Without any keys the app still runs: assets, multipliers, pause flags, policies and Chainlink reference prices come straight from Base; DEX prices, liquidity, pools and candles come from the keyless DexScreener and GeckoTerminal APIs behind a shared server-side cache; trades route through KyberSwap, Velora and Aerodrome. Keys add providers and features:
