## Core Concepts

| Term             | Meaning                                                                                                                                                                                                        |
| ---------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Address**      | Wallet address. EVM chains use `0x...` format, Solana uses base58.                                                                                                                                             |
| **Chain ID**     | Numeric blockchain identifier. `1` = Ethereum mainnet, `137` = Polygon, etc. See [supported chains](./methods/portfolio/v5.0/general/supported_chains/method/get).                                             |
| **Timerange**    | Period for historical calculations. Values: `1day`, `1week`, `1month`, `1year`, `3years`. Counted backwards from current time.                                                                                 |
| **Snapshot**     | Point-in-time view of assets. By default returns current state; optional `timestamp` parameter returns historical state.                                                                                       |
| **Metrics**      | Aggregated historical data for a timerange: profit/loss, ROI, volume of inflows and outflows, etc.                                                                                                             |
| **Protocol**     | DeFi application where user has positions (Aave, Uniswap, Compound, etc.). See [supported protocols](./methods/portfolio/v5.0/general/supported_protocols/method/get). Does not include simple token holdings. |
| **Native token** | Chain's base currency (ETH on Ethereum, MATIC on Polygon). Represented as `0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee` in API responses.                                                                       |
