Custom development/DeFi platform & protocol development
Blockchain & digital trust

Turn protocol rules into a usable product.

Build decentralised finance applications with explicit transaction rules, wallet journeys and operating controls. We scope staking, lending, liquidity and reward workflows alongside contract integration, position data, reconciliation and the tools your operators need.

SEE HOW THE TECHNOLOGY WORKS

A shared record. A clear chain of responsibility.

INTERACTIVE WORKFLOWIllustrative engineering scenario

Establish the source

Define who supplies the record, what the source system verifies and who is allowed to sign.

Read the complete workflow
  1. Establish the source

    Define who supplies the record, what the source system verifies and who is allowed to sign.

    A business record and identified issuer → An authorized signed assertion

  2. Coordinate participants

    Agree the participant permissions, validation rules and correction process before selecting the network design.

    Signed record + network rules → A consistent shared event history

  3. Connect the workflow

    Connect records to enterprise systems and make the audit trail inspectable. A ledger records a claim; it does not independently prove the physical event.

    Recorded event + integration scope → Traceable system updates

WORKFLOW BLUEPRINTIllustrative delivery design
INPUTS TO DEFINE

Protocol rules, transaction states and participant roles

Chain, oracle, wallet and provider requirements

Risk assumptions, review owners and operating responsibilities

REVIEWABLE OUTPUT

A protocol specification and scenario-based test plan

Define deposits, withdrawals, rewards, fees and any collateral or liquidation rules. Map chain, oracle and provider dependencies, privileged actions and user disclosures. Agree test scenarios for stale prices, liquidity constraints and interrupted transactions.

WHAT WE DEFINE AND DELIVER

Practical artifacts. A shared definition of done.

The exact scope follows discovery. These are the building blocks we discuss, specify and review together.

  • Protocol requirements, state models and risk assumptions
  • Staking, lending, liquidity or reward modules within agreed scope
  • Wallet, custody-provider and price-data integrations
  • Position dashboards, event indexing and accounting reconciliation
  • Approval roles, pause controls and exception handling
  • Scenario tests, review evidence and deployment procedures
HOW THE PIECES CONNECT

Architecture with your operation in mind.

Application and wallet → protocol contracts → chain events and price-data dependencies → indexed positions → reconciliation and operator controls. Off-chain calculations, privileged keys and external providers remain explicit parts of the trust model.

Designed around real constraints.

  • Block Gemini provides scoped engineering, not investment advice, a guaranteed yield or a promise of liquidity. Operating permissions and financial obligations belong to the responsible business and its advisers.
  • Testing and code review do not make a protocol exploit-free. Independent audits, economic risk review and provider due diligence are separate, explicitly agreed work.
FIND THE RIGHT STARTING POINT

A product where it fits. A custom build where it matters.

Specify how value moves, who can act and what happens when a dependency fails. Build the protocol, customer interface and operator controls around the same rules.

Bring your objective and the people it should help. We will shape a first scope and the evidence needed to move forward.

A CLEAR PATH THROUGH DELIVERY

One plan. Visible progress.

A complete build, a focused integration or specialists alongside your team. The engagement follows the scope—not a fixed team template.

  1. 01

    Discover

    Define users, the process, constraints and a useful first measure of success.

  2. 02

    Design

    Make the interface, architecture, data and integration decisions visible.

  3. 03

    Build & evaluate

    Deliver working increments and test the task, permissions and difficult cases.

  4. 04

    Release & evolve

    Agree rollout, recovery, handover and the people responsible for ongoing operation.

BEFORE YOU START

Good questions. Clear answers.

Do you build new protocols or integrate existing ones?

Both can be assessed. A new protocol requires explicit rules and threat modelling; an integration requires review of the chosen contracts, permissions and dependencies. We define the accountable scope before implementation.

Which DeFi features can be included?

The scope can include staking, reward distribution, lending, borrowing, liquidity interfaces, position dashboards and operator tools. Each module needs its own transaction rules, data dependencies and acceptance checks.

Can the platform connect to existing custody and reporting systems?

We assess available APIs, signing responsibilities, event data and accounting requirements. Custody, eligibility and reporting integrations are included only where the operator has the required access and agreements.

What does a first engagement produce?

A bounded protocol or integration specification, user and operator journeys, dependency map and testable pilot scope. Delivery milestones follow the actual design, review requirements and access to the necessary systems.
