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.

Rama

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

Auto-Custodia

The practice of personally controlling your cryptographic private keys rather than entrusting them to a third party (exchange, custodian). Self-custody follows the principle 'not your keys, not your coins.' Hardware wallets and properly secured seed phrases enable self-custody. Risks include key loss (no recovery) and social engineering attacks.

Rama

Smart Contract Risk

The risk that bugs, logic errors, or exploitable vulnerabilities in on-chain program code could lead to loss of user funds. Smart contract risk is inherent to all DeFi participation because programs are immutable once deployed (unless upgradeable) and handle real value. Mitigations include professional security audits, formal verification, bug bounties, timelocks on upgrades, and starting with small amounts. Even audited programs can contain undiscovered vulnerabilities.

RPC (Remote Procedure Call)

The API interface for interacting with a blockchain node. Clients send JSON-RPC requests to read account state, submit transactions, and subscribe to events. Solana RPC methods include getAccountInfo, getBalance, sendTransaction, and simulateTransaction. Public RPCs have rate limits; production dApps use dedicated providers (Helius, Triton, QuickNode).

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.

Web3

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).

Web3

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.

Web3

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.
