BNB Smart Chain development: contracts and dApps
BNB Smart Chain is EVM-compatible, so contracts are written in Solidity with familiar Ethereum tools. We build contracts for your product and the app around them, describe the owner rights in plain language and hand the keys to your signers.
Solidity, your keysBNB Smart Chain in brief
From the BNB Chain documentation, read on 15 November 2026.
- EVM-compatible
BNB Smart Chain supports EVM-compatible smart contracts and the existing Ethereum tooling. Contracts are written in Solidity.[1]
- Proof of Staked Authority
Validators take turns producing blocks under PoSA consensus. The consensus model differs from Ethereum’s, and we take that into account when we review the project’s risks.[1]
What we build on BNB Chain
Contracts and the product around them.
A fork or a contract built for your product
Why ready-made code from the internet often costs more in the end.
| A fork or a contract built for your product | Fork or generator | Built for your product |
|---|---|---|
| Owner rights | Preset: minting, burning, fees | Only those agreed and documented |
| Other networks | BNB Smart Chain only | The same Solidity on Ethereum or a layer 2 |
| User questions | Nobody can explain the code | A plain-language spec and verified source |
| Keys | One owner wallet | A multisig held by your signers |
BNB Chain or another EVM network
The code is the same; users and the risk model decide.
- Users or partners already work on this network
- You need Ethereum tooling and modest fees
- The project targets a foreign market where this network is common
- Users hold wallets on Ethereum or a layer 2
- Ethereum mainnet’s security model matters to you
- Auditors and partners work on another network
How the work goes
From the rules to a launch from a multisig.
- Agree the rules
Roles, owner rights and upgrades in plain language.
- Testnet
Contracts and the dApp on the BNB Smart Chain test network.
- Independent audit
An audit firm reviews the code; we fix the findings.
- Launch from a multisig
Source verified, keys with your signers.
About BEP-20 tokens
BEP-20 is the BNB Smart Chain version of the ERC-20 interface; in code the difference is minimal. But a token for users in Kazakhstan may be issued only in the cases the law allows, so we build such projects for clients with a licence or registration, or for foreign markets. We do not run token sales, listings or promotion.

Networks, services and the law.
Checked on 15 November 2026
This is not legal advice. Laws change: before launch, check the current version on adilet.zan.kz and talk to a lawyer or accountant.
Short and to the point.
What is the difference between BEP-20 and ERC-20?
In code, very little: BEP-20 is the BNB Smart Chain version of the ERC-20 interface, so the same Solidity and tools work. Fees, validators and wallets differ, and we explain that at the start.
Which wallets work with BNB Smart Chain?
EVM wallets that support the network, such as MetaMask with the network added, and mobile wallets via WalletConnect. The app can offer to add the network for the user when they connect.
Can we move a contract from Ethereum?
Usually yes: the network is EVM-compatible, so the same Solidity is redeployed. Addresses, keys and user data are moved under a separate plan.
How much does BNB Chain development cost?
There is no separate price in our price list. We name it after the brief and fix it in the contract. Network fees and the external audit are paid separately.
Do we need a licence to issue a BEP-20 token?
We need no licence to develop it. Issuing digital assets to users in Kazakhstan is allowed only in the cases the law sets out, and the client needs the status. Their lawyer decides this.
What should run on BNB Chain?
Describe the product and users; we reply quickly with a scope.
