        definition: A distributed ledger that records transactions in blocks linked cryptographically
      - term: Chain
        definition: A specific blockchain network identified by a chain ID or name (e.g., ethereum, polygon, bsc)
      - term: EVM
        definition: Ethereum Virtual Machine — the runtime environment for smart contracts on Ethereum-compatible chains
      - term: Smart Contract
        definition: Self-executing code deployed on a blockchain at a specific address
      - term: Wallet Address
        definition: A public hexadecimal identifier derived from a cryptographic key pair that can hold and send assets
      - term: Transaction
        definition: A signed instruction from a wallet that modifies blockchain state
      - term: Block
        definition: A batch of confirmed transactions grouped and added to the blockchain
      - term: Gas
        definition: The unit measuring computational effort required to execute operations on EVM-compatible blockchains
      - term: Nonce
        definition: A sequential counter for transactions from a wallet, ensuring transaction ordering

  - name: Token Standards
    description: Fungible and non-fungible token standards
    terms:
      - term: ERC-20
        definition: The Ethereum standard for fungible tokens — interchangeable units with name, symbol, and decimals
      - term: ERC-721
        definition: The Ethereum standard for non-fungible tokens (NFTs) — unique tokens with individual ownership
      - term: ERC-1155
        definition: A multi-token standard supporting both fungible and non-fungible tokens in one contract
      - term: Token Decimals
        definition: The number of decimal places for a fungible token — typically 18 for ETH and 6 for USDC
      - term: Total Supply
        definition: The total number of tokens in existence for a given contract
      - term: Allowance
        definition: The amount of tokens a spender is authorized to transfer on behalf of a token holder (ERC-20)

  - name: NFT Concepts
    description: Non-fungible token specific terminology
    terms:
      - term: NFT
        definition: Non-Fungible Token — a unique, indivisible digital asset on a blockchain
      - term: Token ID
        definition: The unique numerical identifier for a specific NFT within a collection contract
      - term: Collection
        definition: A group of NFTs deployed under a single smart contract address
      - term: Metadata
        definition: Structured data describing an NFT including name, description, image, and attributes
      - term: IPFS
        definition: InterPlanetary File System — a decentralized storage protocol commonly used to host NFT metadata
      - term: Mint
        definition: The process of creating a new NFT and recording it on-chain

  - name: DeFi Concepts
    description: Decentralized finance terminology
    terms:
      - term: DEX
        definition: Decentralized Exchange — an automated market maker protocol for trading tokens without a central intermediary
        aliases: [Decentralized Exchange]
      - term: Market Cap
        definition: Total market capitalization — current price multiplied by circulating supply
      - term: Trading Volume
        definition: The total value of tokens traded over a period (commonly 24 hours)
      - term: Price Impact
        definition: The effect a trade has on the market price due to pool depth
      - term: Liquidity Pool
        definition: A smart contract holding token reserves that enables decentralized trading

  - name: Uniblock Platform Concepts
    description: Concepts specific to the Uniblock API platform
    terms:

        definition: Uniblock's higher-level API that abstracts multiple data providers into a single endpoint
      - term: Direct API
        definition: Uniblock's pass-through API for accessing provider-specific endpoints not yet in the Unified API
      - term: JSON-RPC API
        definition: Uniblock's unified endpoint for standard JSON-RPC blockchain node calls across 300+ networks
      - term: Provider Routing
        definition: Uniblock's automatic selection of the best upstream data provider based on reliability and cost
      - term: Multi-Chain
        definition: Support for interacting with multiple distinct blockchain networks through a single interface
      - term: Cross-Chain
        definition: Operations or data that span multiple blockchain networks
      - term: Failover
        definition: Automatic retry using an alternative provider when the primary provider fails
      - term: Chain ID
        definition: A numeric identifier uniquely identifying a blockchain network (e.g., 1 for Ethereum mainnet)
      - term: Webhook
        definition: An HTTP callback that Uniblock uses to deliver real-time blockchain event notifications
