Sandbox & Testnet

Brale provides a sandbox environment to simulate requests.

Only testnets (Sepolia, Solana Devnet, Base Sepolia, etc.) are supported in sandbox. Fiat flows and blockchain mainnets (Ethereum, Solana, etc) are not supported in sandbox.

See the full set of supported blockchain networks.

1. Create API Credentials scoped to Testnet​

Create an application on the Settings page in the Dashboard.

Select Testnet as Network and enable all resources.

2. Mint Tokens on Testnets​

When you submit a mint in sandbox, we skip the fiat leg and immediately mint on-chain. This simulates a onramp transaction, and also acts as a faucet to easily mint tokens to use in other flows (payouts, etc.).

  }
}

3. Burn Tokens on Testnets​

When you submit a redemption in sandbox, we immediately burn on-chain and skip the fiat payout. This simulates an offramp transaction.

    "value": "100",
    "currency": "USD"
  },
