Start here
Welcome to the Safrochain developer portal. This section is for app and integration developers: wallets, remittance flows, dApps, and CosmWasm contracts. For nodes, validators, and CLI reference, use the Infra section.
What is Safrochain for developers?
Safrochain is a Cosmos SDK Layer-1 built for mobile-first payments and IBC-connected economies.
| Constant | Testnet | Mainnet |
|---|---|---|
| Chain ID | safro-testnet-1 | safrochain-1 |
| Base denom | usaf | usaf |
| 1 SAF | 1_000_000 usaf | 1_000_000 usaf |
| Bech32 prefix | addr_safro | addr_safro |
You integrate via RPC / REST, CosmJS or Cosmos Kit, mobile SDKs, and CosmWasm smart contracts. Human-readable sends use SafHandle.
Why build here?
- Low, predictable fees via globalfee (see chain constants)
- IBC to Noble (USDC) and Osmosis (see IBC channels)
- SafHandle:
@nameand phone-to-address resolution (hub) - CosmWasm for on-chain logic (FeePay, tokenfactory, custom contracts)
- Mobile-first design for remittance and wallet apps across African markets
