Centurion Docs
Getting started
Setup takes about a minute. Sign in, pick your stocks, press one button. No wallet popups, no signatures, no gas.
What you need
- A Google or X account, or an Ethereum wallet, to sign in
- Whatever you already trade with, on any of the 10 chains. Round-ups are paid out of the wallet that spent, in USDC, USDG or the chain's own coin
Step by step
Sign in
Google, X, or a wallet. That creates your Centurion account with its own wallet. The keys live in Privy's secure enclaves; Centurion can sign for that wallet only within limits you can see, and you can export the key at any time.
Pick your stocks
Choose which Stock Tokens your spare change buys, and the split between them (50% AAPL, 30% TSLA, 20% SPY). Press Continue and they are saved.
You can change your picks any time. New picks apply to the next purchase.
Choose how much to round up, then turn it on
Pick the spare-change size (1×, 2×, 5×, 10×) and when to buy. One click turns round-ups on for every wallet on your account, on all 10 chains at once. Centurion pays the gas.
Optional settings
- Multiplier: 2× means $4.35 becomes $1.30 instead of $0.65
- Boost: Adds a percentage of every payment on top (+2%)
You're done
Import the wallets you already trade with, or export this one into MetaMask or Rabby, then trade as usual: Hyperliquid, Polymarket, Uniswap, wherever. Come back any time to change your stocks.
Using a wallet you already have
On the Wallets page you can import a wallet by pasting its private key. It goes to Privy, not to Centurion; the address stays the same. From then on its trades are rounded up too, into the same pot, buying the same stocks.
You can also export the key of any of your wallets to use it in MetaMask or Rabby. Round-ups keep working on trades you make there, on every chain the wallet is used on.
