Blockchain, engineered for trust.

We build stablecoin smart contracts, tokenisation platforms, DeFi protocols and dApps with the discipline of financial infrastructure, and interfaces people actually understand.

Stablecoin smart contracts

Anatomy of a stablecoin contract.

A stablecoin is a promise that every token is backed and redeemable. We engineer the contracts that keep it, whether fiat-backed, collateralised or built for payments, with the controls issuers, auditors and regulators expect.

  1. 01

    Payments & interfaces

    Issuer dashboards, mint and redemption portals, and wallet and merchant integrations. Gasless approvals and transfers make paying in stablecoins feel like paying by card.

  2. 02

    Mint & burn

    Role-gated issuance and redemption tied to your banking and reserve workflows, with per-minter allowances, rate limits and native cross-chain burn-and-mint.

  3. 03

    Compliance controls

    Allowlists, blocklists, account freezes and sanctions-screening hooks, built to support the controls issuers need under frameworks such as the EU's MiCA and the US GENIUS Act.

  4. 04

    Governance & safety

    Multisig and timelocked admin actions, an emergency pause and strict role separation, so no single key can mint, freeze and upgrade. Upgrades follow a deliberate path, or the contract is immutable.

  5. 05

    Reserves & proof of reserve

    Proof-of-reserve oracles that refuse to mint beyond verified reserves, supply reporting across every chain, and data for your attestation reports.

(04) What we build

Key things we build on-chain.

01

Stablecoin smart contracts

Fiat-backed, collateralised and payment stablecoins with role-gated minting, compliance controls and proof-of-reserve checks.

02

Smart contract development

Secure, gas-efficient contracts in Solidity and Rust, upgradeable or immutable, with audit-ready documentation.

03

Security reviews & audit prep

Threat modelling, invariant and fuzz testing, internal reviews and hands-on support through independent audits.

04

Tokenisation & real-world assets

Tokenised funds, treasuries, invoices and loyalty points, with transfer restrictions and investor allowlists built in.

05

DeFi & on-chain payments

Vaults, lending, staking and DEX integrations, plus stablecoin checkout, merchant settlement and on/off-ramps.

06

dApps, wallets & NFTs

Fast front-ends with wallet and smart-account support, NFT minting, marketplaces and token-gated experiences.

07

Cross-chain & layer 2

Deployments across Ethereum, layer-2 networks and Solana, with canonical bridging instead of fragmented wrapped tokens.

08

Indexing & monitoring

Indexers, event pipelines, dashboards and real-time alerts, so you see what your contracts are doing as it happens.

09

Enterprise blockchain

Permissioned networks and integrations that connect on-chain records to your ERP, banking and identity systems.

Approach

Security is the product.

A transparent process with demos every sprint, so you always know what's shipping and why.

  1. 01

    Model the system

    Token flows, roles, reserves and threat models are defined up front, before a single line of Solidity is written.

  2. 02

    Build & test

    Contracts built on battle-tested standards like OpenZeppelin, with unit, fuzz and invariant tests ("supply never exceeds reserves").

  3. 03

    Audit & harden

    Internal security reviews, testnet deployments, coordination with independent auditors and fixes for every finding.

  4. 04

    Launch & monitor

    Mainnet deployment, verified source code, live monitoring and alerting, and incident runbooks written before launch day.

FAQ

Questions, answered.

What kinds of stablecoins can you build?

Fiat-backed tokens redeemable one-to-one against reserves, over-collateralised crypto-backed stablecoins, tokens backed by treasuries or commodities, and private payment or settlement tokens for B2B, treasury or loyalty use. We'll help you choose the model that fits your licence, users and liquidity plans.

How do you keep a stablecoin's supply honest?

Minting is limited to approved roles with allowances and rate limits, and can be gated by proof-of-reserve oracles so supply can't exceed verified reserves. Invariant tests check that rule on every build, and on-chain monitoring alerts you if anything drifts.

Do you handle the regulatory side?

We're engineers, not lawyers. We build the technical controls regulators expect, such as freezing, blocklists, audit trails, role separation and reporting, and work alongside your legal and compliance advisers, who own the regulatory strategy.

Which blockchain should we build on?

It depends on your users, costs, throughput and ecosystem. We'll compare options such as Ethereum, layer-2 networks (Base, Arbitrum, Polygon) and Solana, and recommend the right fit. Stablecoins often launch on several chains at once.

How do you keep smart contracts secure?

We follow established standards, write extensive automated tests including fuzzing and invariants, run internal reviews and coordinate independent third-party audits before mainnet.

Do you still build NFT platforms?

Yes. Minting, marketplaces, royalties and token-gated experiences are still part of what we do, alongside stablecoins, tokenisation and DeFi.
