BlockSprout / Non-custodial blockchain software

Build on-chain.
Keep control.

Configure and deploy smart contracts on BNB Chain and Ethereum without writing code. Your wallet signs the deployment. Your private keys stay yours.

Software infrastructure. Not an exchange or a custody service.

Our operating promises

Your keys. Always.

We never access your private keys.

No customer custody.

We build software, not deposit accounts.

Direct to the chain.

Deploy using your own wallet.

01 / The development platform

From an idea to
a deployed contract.

Start with templates based on OpenZeppelin v4.9.3 standards. Shape the mechanics around your project, then deploy from your browser.

Need something outside the template?

Custom smart contract development is available for project-specific logic and infrastructure.

  1. 01

    Choose your foundation

    Select a smart contract template for your project. Review its mechanics before committing to a deployment.

  2. 02

    Make the parameters yours

    Customize token supply, transaction fees, reward structures and lock periods to match your requirements.

  3. 03

    Sign with your own wallet

    Deploy directly to a supported public blockchain. BlockSprout never receives your private keys.

02 / Beyond deployment

Utility, expressed in code.

Four Ever Coin Plus · FEVR

A fixed-supply token on BNB Chain with automated reward distribution. Transfers and claims execute through immutable smart contract logic; BlockSprout does not operate the exchange.

Four Ever Coin X · FEVRX

In development

A non-custodial token rental marketplace being built for temporary utility rights. Smart contract escrow is designed to handle collateral, rental payments and token returns.

03 / Software pricing

Choose your build path.

Service fees for software and development—not deposits, token purchases or investment products.

Platform subscription

$99 / month

For ongoing access to the browser-based smart contract platform.

Explore platform options

Single deployment

$499 / contract

A per-deployment option when you have one contract to launch.

View deployment options

Custom development / scoped to your project

$5,000–$150,000 per project

Review available offerings and terms before purchase. Blockchain transactions carry network fees and smart contract risks. Template standards do not eliminate the need to review your configuration.
