## About Aptos

Aptos is a Layer 1 blockchain built with Move, a resource-oriented programming language originally developed at Meta. The Aptos blockchain is designed for scalability, safety, and upgradeability.

### Key Aptos Concepts

- **Move Language**: A resource-oriented programming language for smart contracts
- **Accounts**: Identified by 32-byte addresses (64 hex characters, prefixed with 0x)
- **Resources**: Typed data stored under accounts, defined by Move modules
- **Modules**: Smart contract code deployed on-chain
- **Transactions**: Signed messages that modify blockchain state
- **Events**: Structured logs emitted during transaction execution
- **Gas**: Computation and storage fees paid in APT (the native token)

## URL Construction Guide

**Base URL**: `https://explorer.aptoslabs.com`

All URLs default to **mainnet**. To specify a network, append `?network=testnet`, `?network=devnet`, or `?network=local`.

### Page Routes and Tabs

Each detail page has tabs accessible via path segments:

#### Transactions
- `/transactions` — paginated list of recent transactions
- `/txn/{version}` — transaction by version number (integer)
- `/txn/{hash}` — transaction by hash (0x-prefixed hex)
- Tab paths: `/txn/{id}/userTxnOverview`, `/txn/{id}/events`, `/txn/{id}/payload`, `/txn/{id}/changes`, `/txn/{id}/balanceChange`

#### Accounts
- `/account/{address}` — account overview (redirects to `/account/{address}/transactions`)
- Tab paths: `/account/{address}/transactions`, `/account/{address}/coins`, `/account/{address}/tokens`, `/account/{address}/resources`, `/account/{address}/modules`, `/account/{address}/info`
- Module source: `/account/{address}/modules/{moduleName}` — view source of a specific module

#### Blocks
- `/blocks` — paginated list of recent blocks
- `/block/{height}` — block by height (integer)
- Tab paths: `/block/{height}/overview`, `/block/{height}/transactions`

#### Validators
- `/validators` — active validator set with performance metrics
- `/validators/delegation` — delegation/staking information

#### Coins and Tokens
- `/coins` — list of known coins/fungible assets
- `/coin/{type}` — coin details by Move type (e.g., `/coin/0x1::aptos_coin::AptosCoin`)
- Tab paths: `/coin/{type}/info`, `/coin/{type}/transactions`
- `/fungible_asset/{address}` — fungible asset by metadata address
- `/token/{tokenId}` — individual NFT/token details

#### Other Pages
- `/analytics` — network analytics charts (TPS, DAU, gas, supply)
- `/verification` — on-chain verification tools

### Network Query Parameter

Append to any URL:
- `?network=mainnet` (default, can be omitted)
- `?network=testnet`
- `?network=devnet`

Example: `https://explorer.aptoslabs.com/account/0x1/modules?network=testnet`

## Key Addresses and Types

| Address | Description |
|---|---|
| `0x1` | Aptos Framework — core modules (coin, account, staking, governance, fungible_asset) |
| `0x3` | Token v1 standard (legacy NFT/token module) |
| `0x4` | Token v2 / Digital Asset standard (current NFT standard) |

| Type | Description |
|---|---|
| `0x1::aptos_coin::AptosCoin` | Native APT coin type |
| `0x1::coin::CoinStore<T>` | Token balance for coin type T |
| `0x1::account::Account` | Basic account information resource |
| `0x1::staking_contract::StakingContract` | Staking delegation resource |

| `0x4::collection::Collection` | NFT collection v2 data |
| `0x1::fungible_asset::Metadata` | Fungible asset metadata |

## Data Interpretation Guide

### Amounts and Units
- **Octas**: The smallest unit of APT. 1 APT = 100,000,000 Octas (10^8)
- Raw amounts in API responses and on-chain data are always in Octas
- The explorer displays converted APT values with decimal notation
- Example: `150000000` Octas = `1.5` APT

### Transaction Identifiers
- **Version**: A sequential integer (0, 1, 2, …) assigned to every committed transaction. This is the primary identifier.
- **Hash**: A 32-byte SHA3-256 hash (64 hex chars, 0x-prefixed). Used to look up transactions before they are committed or when the version is unknown.
- Both `/txn/123456` (version) and `/txn/0xabc...def` (hash) are valid.

### Address Format
- 32 bytes = 64 hex characters, always 0x-prefixed
- Short form: leading zeros can be omitted (e.g., `0x1` is `0x0000…0001`)
- The explorer accepts both short and full-length addresses

### Move Resource Type Syntax
- Format: `{address}::{module_name}::{struct_name}`
- With generics: `{address}::{module_name}::{struct_name}<{type_param}>`
- Example: `0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin>`

### Epochs and Rounds
- **Epoch**: A period (~2 hours on mainnet) during which the validator set is fixed
- **Round**: A sub-unit within an epoch for consensus
- Epoch boundaries trigger staking reward distribution

### Sequence Numbers
- Each account has a sequence number that increments with every transaction sent
- Analogous to nonces in Ethereum
- Visible on the account info tab

## Example Prompts and Answers

Below are worked examples showing how to route user questions to explorer URLs.

**Q: "What is transaction 582947613?"**
A: Visit `https://explorer.aptoslabs.com/txn/582947613` — this shows the full transaction details including sender, payload, events, and gas.

**Q: "Show me the balance of 0xce462d0a77e4f6e7e9be93a08d498e6934fbb8ac02ddd6d5a472dd9dde9f7798"**
A: Visit `https://explorer.aptoslabs.com/account/0xce46…7798/coins` — the coins tab shows all fungible token balances for this account.

**Q: "What modules does the Aptos Framework have?"**
A: Visit `https://explorer.aptoslabs.com/account/0x1/modules` — this lists all Move modules deployed at address 0x1 with viewable source code.

**Q: "Is there an APT coin page?"**
A: Yes — `https://explorer.aptoslabs.com/coin/0x1::aptos_coin::AptosCoin` shows supply, metadata, and recent transactions for native APT.

**Q: "What's the current TPS on Aptos?"**
A: Visit `https://explorer.aptoslabs.com/analytics` — the analytics page shows real-time and historical TPS charts along with other network metrics.

**Q: "Show me block 50000000"**
A: Visit `https://explorer.aptoslabs.com/block/50000000` — shows the block's proposer, timestamp, and contained transactions.

**Q: "How do I check the same account on testnet?"**
A: Append `?network=testnet` to the URL. Example: `https://explorer.aptoslabs.com/account/0x1?network=testnet`

**Q: "What validators are currently active?"**
A: Visit `https://explorer.aptoslabs.com/validators` — shows the active validator set with voting power, performance, and staking info.

**Q: "Where can I see token/NFT details?"**
A: Individual NFTs: `/token/{tokenId}`. Collections are visible via the owning account's tokens tab. Fungible assets: `/fungible_asset/{address}`.

**Q: "Convert 250000000 Octas to APT"**
A: 250000000 ÷ 100000000 = 2.5 APT. The explorer shows converted values automatically.

## API Endpoints Used by the Explorer

The explorer fetches data from these Aptos APIs (for reference — these are not explorer URLs):

### REST API (Node)
- `GET /accounts/{address}` — Account info
- `GET /accounts/{address}/resources` — Account resources
- `GET /accounts/{address}/modules` — Account modules
- `GET /transactions` — Transaction list
- `GET /transactions/by_hash/{hash}` — Transaction by hash
- `GET /transactions/by_version/{version}` — Transaction by version
- `GET /blocks/by_height/{height}` — Block by height

### Indexer GraphQL API
- Account transactions, token ownership, collection data
- Event history, aggregated analytics

## Limitations

The explorer **cannot** do the following:
- **No historical price data**: The explorer shows on-chain data only, not market prices or charts
- **No cross-chain data**: Only Aptos L1 is supported — no bridged asset tracking or multi-chain views
- **No wallet signing**: The explorer is read-only for browsing; it does not initiate or sign transactions
- **No full-text search of code**: Module source can be viewed but not searched across all accounts
- **No time-range queries**: Transaction/event history is paginated, not filterable by date range
- **No private/encrypted data**: Only public on-chain state is displayed
- **Testnet/devnet data resets**: These networks reset periodically; historical data may be unavailable

---

## Technical Stack

- **Frontend**: React with TypeScript
- **Routing**: TanStack Router (file-based routing)
- **Data Fetching**: TanStack Query (React Query)
- **UI**: Material-UI (MUI)
- **Build**: Vite with SSR
- **Deployment**: Netlify
