Creating a token: ERC-20, BEP-20, SPL or Jetton, and what comes with it

What token creation and deployment include

Quick test: Write your token name, symbol, supply and decimals on one line. Everyone on the team should agree before deployment.

Token creation and deployment takes a defined token specification through implementation and release on its chosen network. The service can include contract or token configuration, deployment, metadata preparation, and support with publishing or verifying relevant information in an explorer. The exact plan is agreed before implementation, so you can see what is included and what remains with your team.

The work is useful for a project preparing a token launch, adding a token to an existing product, or replacing assumptions with a documented technical specification. It is not a substitute for deciding how the token should function commercially or legally. If the token needs connected product features, we can map those requirements alongside smart contract development or a wider Web3 development project.

Before work starts, share:

• The intended network and token standard, if already chosen.
• Token name, symbol, supply approach, and any required decimal setting.
• Any transfer, minting, burning, pausing, or administrative behavior you expect.
• Who will control the deployment wallet and approve the final configuration.
• Existing design notes, product requirements, or metadata assets.

If a requirement is undecided, mark it as open rather than letting it become an accidental default. That gives the team a clear point to resolve before code is finalized.

Which token standard fits your network?

The network and product requirements determine which token format to build; the standards are not interchangeable labels. ERC-20 is associated with Ethereum, BEP-20 with BNB Chain, SPL with Solana, and Jetton with TON. Start by naming where users will interact with the token, then confirm that the selected standard fits the surrounding product and its planned integrations.

A practical selection review asks what the token needs to do, who will administer it, and which existing product components must recognize it. If a team requests multiple networks, treat each deployment as a separate plan: confirm whether the token behavior, supply plan, metadata, and operational controls should match across networks. Do not assume that deploying on more than one network automatically creates a connection or shared supply between them.

For a product with application requirements, discuss the token alongside the dApp build rather than treating deployment as the whole launch. For a wallet-facing product, include the intended wallet experience in the requirements and coordinate with crypto wallet development.

A good brief records the selected network, standard, intended token behavior, admin roles, and any unresolved decisions. The delivery team can then check those choices before implementation and explain what needs a client decision. That early review helps avoid late changes caused by a mismatch between the token specification and the product that will use it.

Contract settings and handoff materials

The what you receive should make clear what was specified, what was deployed, and how your team can refer to the result. The contract or token configuration follows the agreed requirements; the deployment handoff records the relevant network and deployment reference, while metadata materials are prepared within the agreed plan.

Before implementation, a developer and delivery lead review the project inputs with you. They identify missing decisions, flag settings that need explicit approval, and confirm who can authorize deployment. You receive the configuration for review in plain language, including any admin or update controls that are part of the agreed design. This is a review of the planned work, not a claim that the token has undergone an independent security audit.

A typical handoff can include:

• The approved token specification and the implemented features in plan.
• The deployment reference and network details supplied at release.
• Source-code verification support where the relevant explorer provides a process for it.
• Metadata files or values prepared for the agreed token presentation.
• Notes on any remaining actions owned by the project team.

If the token will appear in a website or product, make sure the content and user journey are ready to explain its purpose. We can coordinate token details with Web3 website and landing development, but separate product or marketing what you receive should be listed in the plan rather than assumed to be part of token deployment.

How deployment, verification and metadata fit together

Common mistake: Leaving owner rights unclear. State who can mint, pause or change settings, and why.

Deployment releases the agreed token implementation on the selected network; verification and metadata are related follow-up tasks, not substitutes for checking the token specification. We plan them together so the project team knows what information needs to be ready and which actions require access to a project-controlled wallet or account.

The sequence is straightforward: confirm the network and configuration, review the implementation, prepare the required deployment access, deploy after approval, then support the agreed verification and metadata tasks. The deployment wallet must be controlled by the project or by an authorized person acting under its instructions. The project team should also ensure it can provide the network's required transaction-fee asset before the release is scheduled.

Explorer verification generally involves submitting information about the deployed source through the explorer's available process. It is separate from an independent audit, and it does not establish that the token's design is appropriate for every use. Metadata should be prepared with consistent names and project details; how it appears to users can vary by the explorer, wallet, or product displaying it.

If the token is one part of a larger Telegram product, coordinate requirements with Telegram bot and mini app development early. That helps align token details with the app experience and avoids treating a deployment reference as a finished integration. We confirm the planned order and handoff items with your team before the release.

What can affect deployment or explorer verification

The project controls its specification, approval, deployment access, and readiness of required materials; the network and third-party explorer control their own transaction processing and verification interfaces. We plan delivery around the implementation and support work agreed with you, and we report what was completed rather than presenting an external review as our own result.

For this service, the main boundary is explorer verification: an explorer may require specific submission details, and its verification process or display can change independently of the contract work. Token metadata may also render differently across explorers and wallets. We cannot promise that a third-party explorer will approve a submission or display metadata in a particular way, so we identify the target explorer and its visible requirements before handoff and record the outcome.

You can reduce avoidable delays by confirming the deployment wallet owner, providing accurate token details, resolving open contract settings, and keeping the person authorized to approve deployment available. If the project requires a formal security review, specify that separately; deployment and source verification do not by themselves constitute an audit. Our role is to deliver the agreed implementation and deployment work, explain its status, and make clear which remaining actions belong to your team or an external platform.

Your 7-point token settings checklist

Agree these 7 items in writing before anything is deployed. Token settings are hard to change afterwards, and a clear sheet prevents most deployment-day debates. Do the ticking together in one short call, and write down who owns each line before the call ends.

1. Choose the network and the standard.
2. Fix name, symbol and decimals.
3. Fix total supply and who receives it.
4. State owner rights: mint, pause, burn or none.
5. Prepare the logo and metadata files.
6. Plan explorer verification after deploy.
7. Save the contract address and deployment notes.

What to prepare before you ask

A useful request explains the token's purpose, target network, intended behavior, and launch context. You do not need to have every technical choice settled, but you should separate confirmed requirements from questions that need advice. That gives the team a clear basis for estimating plan and for proposing a review before implementation begins.

Send a short project brief with the details you already know: the network or candidate networks; the token name and symbol; how supply should be created or managed; any special transfer or administrative behavior; and who controls the deployment wallet. Include relevant product links or design materials, plus the explorer or wallet where you expect users to see token information. Do not send private keys or seed phrases in a project brief.

MarketingExtra reviews those materials with the project contact, returns questions on missing or conflicting requirements, and confirms the implementation and handoff plan before work proceeds. You will know who is responsible for approvals and what needs to be ready for deployment. If the brief shows that the token depends on other product work, we can discuss the relevant Web3 development services and define the relationship between them.

The next step is to send your target network, token behavior, current specification, and preferred deployment contact to MarketingExtra. We will review the inputs, identify open decisions, and respond with a written plan for the token work.

Send 3 things: your target network, your token behavior, and the wallet that will deploy.

How it works

1. Share the token briefSend the intended network, token behavior, known settings, product context, and deployment contact. Mark undecided items so they can be reviewed before implementation.
2. Confirm the specificationA developer and delivery lead review requirements, identify gaps, and confirm the features and handoff materials included in plan.
3. Review and approve the buildThe team implements the agreed configuration and walks you through the settings that need approval before deployment.
4. Deploy and hand offAfter approval and access are ready, the team coordinates deployment, supports agreed verification and metadata tasks, and shares the completion details.
