# Tavcoin

> Understand Tavcoin, its 18-decimal base units, testnet genesis allocation and the difference between Test TAV and application tokens.

Tavcoin (**TAV**) is Tavchain's native coin. Use Test TAV on testnet to send value and pay transaction fees. Test TAV has no monetary value.

## Units and precision

TAV has **18 decimal places**. Its base denomination is `atav`.

| Display amount | Base amount |
| - | - |
| 1 TAV | 1,000,000,000,000,000,000 atav |
| 0.01 TAV | 10,000,000,000,000,000 atav |
| Smallest unit | 1 atav = 0.000000000000000001 TAV |

Wallets display TAV amounts. Ethereum RPC represents balances and other quantity fields as hexadecimal integers. Keep base amounts in integer-safe types; do not use floating-point arithmetic for account balances.

## Testnet genesis allocation

The testnet genesis allocates a total of **1,000,000 Test TAV**:

| Allocation | Test TAV |
| - | - |
| Four operator accounts | 2,000 each |
| Faucet | 50,000 |
| Validator-grant reserve | 50,000 |
| Test reserve | 892,000 |

Each genesis validator self-bonds 1,000 Test TAV from its operator allocation. The reserve does not automatically refill the faucet.

This describes the testnet genesis, not mainnet tokenomics or a promise of rewards. Test balances have no announced redemption, airdrop or mainnet conversion entitlement.
