How key features work
What it can ask your wallet to sign
Its code can ask your wallet for eth_sign, approve, increaseAllowance, eth_signTypedData and 4 more. Each of these opens a wallet pop-up you must approve; read it before you click.E167E174E175E168E169E173
It connects to crypto wallets using Privy (wallet login), WalletConnect / Reown, viem, Coinbase Wallet SDK and 4 more. Connecting shows the site your wallet address; it doesn't move funds by itself.E18E19E20E21E22E23
It reads blockchain data (Arbitrum One, Arbitrum Sepolia, Avalanche, Avalanche Fuji and 4 more) to show balances, prices or contract state.E237E238E239
Sign-in and account features show up in its code or traffic (/api/v1/custom_jwt_account/authenticate, /api/v1/recovery/oauth/init, /api/v1/wallets/:wallet_id/deposit_accounts/crypto/orders/:order_id and /api/v1/siwe/authenticate).E36E37E41
Its content loads from its own API while you browse (/api/memecards/reward-config, /api/memecards/catalog, /api/memecards/activity, /api/memecards/leaderboard and 1 more).E29E30E31E32E33
Every sentence above points to one of these. Code references show the file, line:column and the short identifier that matched, never the site's code itself.

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 24 large bundle file(s); those parts weren't fully analysed.
Facts, not judgements: this page describes what the code and traffic show, not anyone's intent. Not financial advice. Case id GhLmmX2c.
