# Glossary

## Account

An address plus a way to authorize it. WalletChan account types include private
key, seed phrase, Ledger, view-only, Safe, and optional Bankr remote signing.

## Address

A `0x` identifier for an EVM account or contract. A name/avatar can label it but
does not replace address verification.

## Allowance / token approval

Onchain permission for a spender contract to move up to a token amount.
Disconnecting a dapp does not revoke it.

## Atomic batch

Several calls that all succeed together or all revert. A sequential batch can
partially complete.

## Bridge

A protocol that moves value/state between networks. Source confirmation and
destination settlement are separate stages.

## Calldata

The encoded function and arguments sent to a smart contract.

## Clear signing

A human-readable description of a contract action, using ERC-7730 or a trusted
local pattern, with decoded/raw fallback.

## Dapp

A website/application that connects to an Ethereum wallet and requests reads,
transactions, or signatures.

## EOA

An externally owned account controlled by a key. EIP-7702 can attach smart
account behavior while retaining the same address.

## Gas

The network execution fee. A gas limit bounds work; fee values influence cost
and inclusion priority.

## Nonce

An account transaction sequence number. Same-nonce higher-fee replacements can
speed up or attempt to cancel a pending EOA transaction.

## RPC endpoint

A server WalletChan uses to read chain state and broadcast signed
transactions.

## Safe

A smart-contract multisig account controlled by owners and a confirmation
threshold.

## Seed phrase

Words that derive a family of private keys/accounts. WalletChan seed accounts
use standard EVM derivation paths.

## Shielded ETH

WalletChan's wallet-wide ready private balance in the configured Privacy Pool.
Its recovery phrase is separate from wallet seed phrases.

## SIWE

Sign-In with Ethereum (EIP-4361), a structured message for proving address
control to a service.

## Slippage

The tolerated difference between quoted and executed swap output. Minimum
received reflects the selected tolerance.

## View-only

An address tracked without a signing secret. Normal prompts are reject-only.

## WalletConnect

A relay protocol that pairs a wallet with another app/session using a `wc:`
URI.
