Chain Parameters
Detailed chain parameters, denomination info, and genesis configuration for the crescendo-1 testnet.
This page contains detailed technical parameters for the crescendo-1 testnet, useful when configuring clients, building transactions, or integrating with the chain.
Chain Identity
| Parameter | Value |
|---|---|
| Chain ID | crescendo-1 |
| Binary | bitsongd |
| Branch | feat-hyperlane |
| Networks Repo | bitsongofficial/networks |
| Docker Image | ghcr.io/bitsongofficial/go-bitsong:feat-hyperlane |
Denomination
| Property | Value |
|---|---|
| Display Denom | TBTSG |
| Base Denom | utbtsg |
| Decimals | 6 |
| Conversion | 1 TBTSG = 1,000,000 utbtsg |
When building transactions, always use the base denomination utbtsg. For display purposes, divide by 10^6 to convert to TBTSG.
// Convert utbtsg to TBTSG for display
const utbtsg = "1000000"
const btsg = Number(utbtsg) / 1e6 // 1.0
// Convert TBTSG to utbtsg for transactions
const amount = Math.floor(1.5 * 1e6).toString() // "1500000"

Gas Configuration
| Parameter | Value |
|---|---|
| Minimum Gas Price | 0utbtsg (testnet only) |
| Default Gas Limit | 200000 |
| Gas Adjustment | 1.5 (recommended) |
The minimum gas price is set to
0utbtsg for easy testing. On mainnet this should always be set to a non-zero value.Genesis Information
The genesis file defines the initial state of the blockchain. Download it from the networks repository:
curl -L https://raw.githubusercontent.com/bitsongofficial/networks/refs/heads/master/testnet/crescendo-1/genesis.json \
-o genesis.json
The genesis file contains initial accounts, chain parameters, and the initial validator set. You can parse it with
jq for specific values:# Get chain ID
jq '.chain_id' genesis.json
# Get staking denom
jq '.app_state.staking.params.bond_denom' genesis.json
