Bucket hoursWhen you buy bucket hours, you purchase a set number of hours upfront.
- Your purchased bucket hours remain valid for 6 months, during this time frame, you can utilize our services until your hours are exhausted or until the 6-month period expires.
- For example, if you invest in 40 bucket hours and use 10 hours within the first month, you will have a remaining 30 hours to utilize over the next 5 months.
- In this case, the developer will work for other projects simultaneously as you have opted for bucket hours and not dedicated hiring.
It's a convenient and efficient way to manage your developer needs on your schedule.

Dedicated/Regular HiringIn dedicated hiring, the number of hours are not fixed like the bucket hours but instead, you are reserving the developer exclusively for your project.
- The developer will work only on your project for a set amount of time.
- You can choose to hire the developer for a week or a month, depending on what your project needs.
- This means our developer will focus exclusively on meeting the needs of your project, without any distractions from other commitments.

Our Blockchain Development Process
Companies choose us for blockchain development because we bring structured execution, deep technical expertise, and a proven track record of delivering secure, scalable distributed systems on schedule.
Planning and Assessment
Every blockchain project starts with fundamental architectural decisions that shape everything downstream — which network to build on, whether to use public or permissioned infrastructure, how consensus will work, and what the security model needs to be. We spend this phase working through those choices methodically, making sure the technical foundation matches your business requirements and compliance obligations before any development begins.
Determine whether you need a public blockchain integration, a permissioned enterprise network, or a hybrid model — and select the appropriate protocol (Ethereum, Hyperledger, Polygon, Solana, Corda) based on your transaction volume, governance needs, and regulatory context.
Map out exactly what logic belongs on-chain versus off-chain, identify the smart contracts required, and define the data structures, token models, and business rules that will be encoded into immutable blockchain logic.
Establish the consensus mechanism, validator structure, and governance model for your blockchain network — whether that's proof-of-stake, proof-of-authority, or Byzantine fault tolerance — along with upgrade pathways and decision-making protocols.
Build a phased delivery plan with blockchain-specific checkpoints — testnet deployment, security audit gates, mainnet migration — and allocate the right mix of blockchain engineers, cryptography specialists, and infrastructure architects to each phase.
Design
Blockchain design goes deeper than interface mockups — it includes the entire data model, the smart contract architecture, the transaction flow, and how users interact with decentralized systems. We prototype the complete user journey alongside the technical architecture, so both the on-chain logic and the user-facing experience are thought through before code gets written.
Design the contract structure, inheritance patterns, access control models, and upgradeability mechanisms — mapping out how each contract interacts, what state it maintains, and where the security boundaries are.
Map the end-to-end flow for every blockchain interaction — wallet connection, transaction signing, gas fee handling, confirmation feedback — ensuring users understand what's happening at each step even if they're unfamiliar with blockchain mechanics.
For projects involving tokens, define the supply model, distribution mechanics, staking rewards, burning mechanisms, and governance rights — ensuring the economic model aligns with long-term sustainability and regulatory requirements.
Create interactive prototypes showing how users will connect wallets, initiate transactions, view blockchain state, and manage assets — with a structured review cycle before moving into development.
Smart Contract Development
With the legal and structural framework confirmed, our blockchain engineers build the smart contracts that will govern every aspect of the token's behaviour — from initial minting through to investor exits. Every contract is written with auditability and upgradeability in mind.
Build the core token contract with the selected standard, encoding all ownership rules, transfer restrictions, and compliance logic directly into the contract code.
Develop contracts that handle investor allocations, vesting schedules, lock-up periods, and any automatic distribution of yield or returns.
Integrate on-chain KYC and allowlist management such that transfer restrictions are enforced at the contract level, rather than at the platform level.
Develop the front-end investor portal and on-chain registry which provides real-time visibility into holdings, distributions, and transaction history for issuers and investors.
Testing & Security Audit
No tokenization contract goes near mainnet without passing through a thorough testing and audit process. Given that these contracts govern real asset ownership and financial rights, the bar for quality is higher than most software projects.
Ensure that each contract function operates as expected in normal scenarios, such as minting, transferring, restricting, burning, and distributing, for all specified investor scenarios.
Assess the contract for potential reentrancy attacks, integer overflow, access control issues, and other typical smart contract vulnerabilities by using automated testing tools as well as manual code analysis.
Ensure that KYC/AML compliance, transfer restrictions, and investor qualification logic operate as expected at the contract level, including scenarios such as changes in jurisdiction or investor status updates.
Hire an independent auditor to examine the contract codebase prior to deployment, and generate a report of findings that can be shared with investors, attorneys, and regulators.
Token Issuance & Deployment
With contracts audited and approved, we manage the full issuance and mainnet deployment — coordinating the technical go-live with the investor onboarding process so everything lands cleanly at the same time.
Deploy all smart contracts to the target blockchain network with final configuration checks, gas optimisation, and deployment verification across all contract addresses.
Run the KYC/AML verification process for the initial investor cohort and configure on-chain allowlists so eligible investors can receive and hold tokens from day one.
Execute the initial token allocation to investors, founders, and any reserved pools — with full on-chain transaction records confirming every distribution.
Connect the token to any pre-arranged exchange listings, OTC desk arrangements, or institutional custodian wallets that are part of the issuance plan.
Post-Launch Management
Token issuance marks the start of a continuous process, not the end of a journey. We offer the infrastructure and tools to ensure your tokenized asset remains in good working order – for investors, for regulators, and for your internal team.
Monitor investor transfers, alert on breaches of restrictions, and keep an ever-green on-chain allowlist reflecting changes to investor KYC status, added jurisdictions, or evolving regulatory requirements.
Automatically or manually initiate yield distributions, dividend payments, or return of capital events according to the schedule set forth in the token’s distribution contract.
When contracts are designed with upgradeability in mind, handle upgrades reflecting changes in compliance, token economics, or platform functionality without affecting existing investor positions.
Offer issuers the on-chain data and reporting functionality required to fulfill their continuous regulatory needs and keep investors apprised of asset performance and token activity.
