# deftools.xyz (Base.tools)

> Free tools for trading on Base, built by @Def7771: live token boards with a Buy/Sell signed in your own wallet, five tools of its own (Aero Vote Radar, Thesis, Stocks on Base, Token Check, Arc Contract Check) and a short hand-picked list of Base apps. Everything reads public onchain and market data in the browser; nothing is custodied, no key leaves the visitor's wallet, and every trade is something the visitor signs.

## Tools

- [Aero Vote Radar](https://aero.deftools.xyz): where to vote veAERO on Aerodrome this week to earn the most. Ranks every pool by dollars paid per vote and splits the voting power across several pools, because piling everything into one dilutes your own share. Read-only, open source. It has its own file with this week's numbers: https://aero.deftools.xyz/llms.txt
- [Thesis](https://deftools.xyz/thesis.html): write one line about what you believe ("ai chips and cloud, no tesla") and get a basket of Coinbase Tokenized Stocks on Base, priced across every pool and bought in one transaction through the KyberSwap aggregator. Paste any Base address to see which of the stocks it holds, what was paid for them (from the USDC that left in the same transaction) and the gain or loss, and sell a basket in one transaction. A stock is left out of a basket, with the reason shown, when its price on Base strays from the real share or its pools are too thin for the amount.
- [Stocks on Base](https://deftools.xyz/stocks.html): all 36 Coinbase Tokenized Stocks on Base, checked live. For each one: is it the official token (address from base.org/stocks), its price on Base against the real share, what a $1,000 buy-and-sell round trip costs, where it trades cheapest, Morpho markets that lend USDC against it, and how Base traded over the last weekend while Wall Street was shut. Stocks whose market on Base is broken are marked "do not buy".
- [Token Check](https://deftools.xyz/check.html): paste a Base or Robinhood Chain token address and get a trust score from 1 to 10 with what it is made of: can you actually sell it, who launched it and what became of their earlier coins, which big holders got coins straight from the deployer, what a $500 exit really returns, and a project read built only from sources it can cite. 3 free checks a day, then 0.1 USDC each.
- [Arc Contract Check](https://araxis33.github.io/arc-contract-check/): paste a contract address on Arc (Circle's chain) and see who can change it: a single key, a Safe multisig or a timelock. [Arc fees](https://deftools.xyz/arc.html) shows live Arc costs in dollars and catches the 18 vs 6 decimals USDC mix-up.

## Homepage

- [deftools.xyz](https://deftools.xyz): four live boards (biggest 24h losers with a volume floor, best gainers, Base blue-chips, the ten most traded tokenized stocks), each row with a Buy/Sell that trades through KyberSwap and is signed in the visitor's wallet, with an allowance for exactly the amount sold. A "My wallet" window lists a wallet's tokens on Base, Ethereum and Robinhood Chain with their value and a Sell button.
- The app list: wallets (Coinbase Wallet, Rabby, Rainbow, Fomo), stocks and launchpads, trading bots, terminals, tracking and alerts, DeFi (Aerodrome, Uniswap, Matcha, Relay, Morpho). Links are direct, no affiliate programs.

Not financial advice. The tools print numbers and hand the visitor's wallet a transaction to confirm; they never hold funds.
