  • signTransaction: asks a wallet to sign transactions (often Solana wallets).E46

How key features work

What it can ask your wallet to sign

Its code can ask your wallet for signTransaction. Each of these opens a wallet pop-up you must approve; read it before you click.E46

signTransaction

Connecting your wallet

It connects to crypto wallets using Privy (wallet login), WalletConnect / Reown, web3.js, Solana web3 / wallet adapter and 2 more. Connecting shows the site your wallet address; it doesn't move funds by itself.E20E21E22E23E24E10

Loading its content

Its content loads from its own API while you browse (/api/value, /__l5e/trackevents, /api/engine/config, /api/config and 2 more).E27E28E29E30E31

/api/value/__l5e/trackevents/api/engine/config/api/config/api/collect/api/keys

Saving data on your device

It saves data in your browser (localStorage and IndexedDB (a browser database)), so some things persist between visits.E26E17E18

Limits

  • We only see what your browser sees: code and requests on a first visit, without logging in or accepting cookie banners. What the servers do with data is invisible from outside.
  • Site code is usually minified (compressed), so names are partly lost and some code may be only partly analysed.
  • Some trackers only load after you accept cookies or log in, so the real list can be longer.
  • We visited from a server in the United States. Sites load different trackers and cookie banners in different countries (visitors in the EU usually get a consent banner first).
  • The tech check compares the site's own words with what its public page loads. Work done on servers, in private code or in separate apps isn't visible here, so 'nothing found' means not visible on the public page, not that it doesn't exist.
  • This text was written from fixed templates because no AI writer was available. It uses exactly the same evidence.
  • REA hit its size budget on parts of 29 large bundle file(s); those parts weren't fully analysed.
