Token Approval

The permission granted to a program or delegate address to spend a specified amount of tokens from your account on your behalf. Token approvals are necessary for DeFi interactions like swapping or depositing into liquidity pools. On Solana, the SPL Token program's approve instruction sets a delegate and approved amount on a token account. Approvals should be set to the minimum needed and revoked when no longer required to limit exposure to potential exploits.

Rama

Revoke Approval

The act of removing a previously granted token spending permission from a program or delegate, preventing it from transferring your tokens in the future. Revoking approvals is an important security practice after interacting with DeFi protocols, especially unfamiliar ones, because outstanding approvals could be exploited if the approved program is compromised. On Solana, tools like Revoke.cash and wallet-built-in features allow users to view and revoke active token approvals.

Programa SPL Token

The original Solana Program Library token program (TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA) that implements fungible and non-fungible token operations. It manages mints (token definitions) and token accounts (balances). Core instructions include InitializeMint, MintTo, Transfer, Burn, Approve (delegation), and Revoke. All SPL tokens on mainnet before Token-2022 use this program.

Autoridad

A pubkey with administrative privileges over a resource—such as the mint authority (can mint tokens), freeze authority (can freeze accounts), upgrade authority (can upgrade a program), or the signer authorized to perform operations on a PDA-controlled account. Authority is a convention, not a runtime concept.

Token Standard

A specification defining how tokens are created and managed on a blockchain. Ethereum: ERC-20 (fungible), ERC-721 (NFT), ERC-1155 (multi-token). Solana: SPL Token (fungible/NFT), Token-2022 (extended features), Metaplex standards (NFT metadata). Standards ensure wallet/marketplace interoperability and composability across the ecosystem.

Web3

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.

dApp (Aplicación 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).

Billetera

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.

Frase Semilla (Mnemónico)

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.
