Key facts for Reading Ethereum wallet requests: connection, signing and calls

Typed signatureProvides structure and domain context, not automatic safety[2]
01

Connection, signing and submission establish different things

Connecting a wallet lets an application request interaction with an account; it is not itself an ERC-20 spending approval. A signature can authorize a message, order, permit or transaction, depending on what is signed.

Signing is also different from submitting. Someone can hold a valid permit and submit it later under its nonce and deadline rules. A request with no immediate gas charge can therefore create consequential authority. Read the verifying contract, chain, spender, amount and validity conditions before treating it as a login.

02

Example: approving a spender is different from paying a recipient

Suppose a decoded request says approve a spender for 100 token units. That changes the permitted spending allowance if executed; it is not the same instruction as transfer 100 units to a recipient.

The ABI is the interface description used to turn bytes into readable function names and arguments. The actual token contract, spender, amount and chain still matter. A familiar function name does not authenticate the destination.

03

A structured message helps show what is being signed

EIP-712 defines typed structured data and domain separation. Fields can include an application name, version, chain and verifying contract. These give software a way to display more context than an opaque byte string.

The standard explicitly does not provide application replay protection by itself. An application still needs appropriate nonces, deadlines or other rules, and the wallet’s presentation cannot establish that the verifier implements them correctly.

04

A preview answers a narrower question than a guarantee

A simulation estimates execution against selected state. A later transaction may encounter a different price, balance or ordering. Treat the preview as evidence about those assumptions rather than a promise of the final outcome.

Account delegation deserves special attention: EIP-7702 authorization can grant persistent execution capabilities. It should not be confused with a routine login signature or permission to view an account.

Direct answers

Questions people ask

Does connecting a wallet move my tokens?

Account exposure alone does not execute a transfer. Additional signatures or transactions can grant authority, so distinguish each request rather than treating every prompt as connection.

Is signing a message safe because it costs no gas?

No. A signature can authorize a later action when presented to a contract or service. Its effect depends on the message and the rules that verify it.

Does readable transaction text prove a contract is legitimate?

No. Decoding explains the requested function and arguments. It does not certify the destination contract, its implementation or the site making the request.

Inspect the evidence

The answer and key facts have stable claim links. These records retain the scope and qualification when reused.

A wallet request can expose an account, sign a message or authorize a transaction; these are different actions. Contract interfaces help decode function names and arguments, while typed-message formats add context to signatures. A request with no immediate gas fee can still authorize a consequential action later.
