# Tangerine

> Tangerine is a permissionless, Ethereum-compatible Layer-1 community blockchain. Blocks every 2 seconds, deterministic finality in seconds, and everything open: anyone can read the chain, transact, and deploy Solidity contracts. No allowlist, no gatekeepers.

Key facts:
- Chain ID (EIP-155): 8264
- Native token: TANG (18 decimals, gas and settlement; fixed 1B supply)
- Block time: 2 seconds, fixed cadence
- Finality: deterministic (GRANDPA), typically seconds
- Execution: full EVM semantics; Solidity contracts deploy unmodified
- Interface: standard Ethereum JSON-RPC
- Public read RPC (no key required): https://rpc.tangerine.network/eth
- Access model: fully permissionless — any funded account can transact and deploy; spam is priced by dynamic fees and storage deposits, not permissioned away
- Treasury: 80% of every transaction fee accrues to an on-chain community treasury

## Live network

- [Explorer](https://explorer.tangerine.network/): live blocks, transactions, and addresses — no sign-up
- Example read (no key):
  curl -s https://rpc.tangerine.network/eth -H 'content-type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}'

## Lineage

Tangerine's chain architecture descends from Satsuma (satsuma.one) — a nod of respect —
rebuilt as a permissionless community chain.
