dApp (Aplicação Descentralizada)

An application with its backend logic running on a blockchain as smart contracts rather than centralized servers. dApps typically have a traditional web frontend that interacts with on-chain programs via RPC. Users authenticate with wallets instead of username/password. Examples: Uniswap (Ethereum DEX), Jupiter (Solana DEX), Magic Eden (NFT marketplace).

Ramo

Web3

The vision of a decentralized internet built on blockchain technology, where users own their data, identity, and digital assets. Web1 was read-only (static pages), Web2 is read-write (platforms like social media), Web3 is read-write-own (permissionless, user-sovereign). Web3 applications use wallets instead of logins and smart contracts instead of centralized servers.

Ramo

Contrato Inteligente

Self-executing code deployed on a blockchain that automatically enforces the terms of an agreement when conditions are met. Smart contracts are immutable once deployed (unless upgradeable), transparent, and trustless. On Solana they're called 'programs'; on Ethereum they're written in Solidity and run on the EVM. They enable DeFi, NFTs, DAOs, and other decentralized applications.

Decentralized Identity (DID)

A W3C standard for self-sovereign digital identifiers created, owned, and controlled by the individual rather than a centralized authority. DIDs use public-key cryptography for verification without traditional identity providers. In blockchain contexts, DIDs map to on-chain addresses and enable verifiable authentication across protocols.

Web3

Custodial vs Non-Custodial

Distinction between services that hold users' private keys (custodial — exchanges like Coinbase) versus tools where users retain sole control of their keys (non-custodial — wallets like Phantom). Non-custodial means only the user can authorize transactions; custodial means trusting a third party with asset security.

Web3

Carteira

Software or hardware that manages cryptographic keys and enables users to sign transactions, view balances, and interact with dApps. Hot wallets (Phantom, Solflare, Backpack) are internet-connected for convenience. Cold wallets (Ledger, Trezor) store keys offline for security. Wallets don't actually 'hold' tokens—they hold the private keys that control on-chain accounts.

Web3

Frase Semente (Mnemônico)

A 12 or 24-word human-readable backup of a wallet's master private key, generated using BIP-39 standard. The seed phrase can deterministically regenerate all derived keypairs (BIP-44 derivation paths). Losing the seed phrase means permanently losing access to all associated accounts. Never share, photograph, or store seed phrases digitally in plain text.

Web3

DeFi (Finanças Descentralizadas)

Financial services built on blockchain smart contracts that operate without traditional intermediaries (banks, brokers). DeFi includes lending, borrowing, trading, insurance, and derivatives. Key properties: permissionless (anyone can participate), composable (protocols can be combined), transparent (open-source, auditable). Solana DeFi TVL has exceeded $5B, led by Jupiter, Raydium, Marinade, and Kamino.
