Arbswap: Is It Safe to Connect a Wallet?
Arbswap should not be treated as safe with a funded wallet simply because it shows a swap, arbitrage route, or profit opportunity. Safety depends on the exact contracts, network, route, and permissions your wallet is asked to approve. Until those details are independently verified, use only a new wallet with no assets you cannot afford to lose.
Connecting is not the same as approving
Connecting a wallet usually lets a site read your public address and request signatures; it does not itself transfer assets. Risk increases when a wallet requests an on-chain transaction or typed-data signature.
An ERC-20 approval permits a specified spender address to move a stated amount of a token. Check the token, spender, and allowance carefully. An approval can remain active after you close the site, so it is not a harmless confirmation.
A connection request exposes your address. A signature may authenticate a session but can also authorize a permit or order. A transaction changes blockchain state, such as an approval, swap, transfer, bridge deposit, or contract call. Reject any prompt you cannot explain plainly. A legitimate connection never requires your seed phrase.
Before approving anything, obtain every contract address from a verifiable project-controlled source—not an ad, chat message, screenshot, or token display name. Check the selected chain’s explorer, confirm verified contract code where applicable, and compare the wallet prompt’s address with independently documented protocol addresses. Familiar methods such as approve, allowance, and transferFrom, defined in the EIP-20 specification, do not prove a spender is trustworthy.
Allowances and quoted profits are not guarantees
Unlimited allowances can let a spender access all of a particular token later if it is malicious or compromised. For an unproven interface, grant no approval. If you have independently verified and chosen a contract, use only the smallest allowance needed for one operation, then review and revoke it when no longer needed. Permit signatures deserve the same caution because they can authorize token spending without a separate on-chain approval screen.
A displayed swap or arbitrage return is not a promise of execution. Liquidity-pool trades can change pool reserves, producing price impact and slippage; another transaction may take the opportunity first, gas can erase the margin, a route can revert, a bridge can delay settlement, or a token can charge transfer fees.
The useful test is a disposable wallet: select the intended network manually, connect without approving or signing, inspect every request, and match every contract address to independent documentation. If you still choose to proceed, test the smallest amount with a capped allowance, confirm the result on an explorer, and revoke unused permissions. If Arbswap cannot provide verifiable contracts, requests an unnecessary unlimited allowance, or presents a signature unrelated to your intended action, stop rather than add funds.
