Decentralised Apps,Audited Before They ShipSolidity, EVM Chains, and Wallets — Built by an In-House UK Team.

A dApp with custom smart contracts typically runs £30,000–£120,000. A standard token or NFT collection with a minting site starts around £15,000; a DeFi protocol with upgradeable contracts, multi-chain deployment, and multiple audit rounds sits at the upper end. Audit fees are quoted separately and passed through at cost.

Eight to sixteen weeks from signed specification to mainnet. That includes a testnet phase where the mechanics are exercised with real wallets, and an external audit cycle with time built in to remediate findings — the step most schedules underestimate.

For most UK commercial use cases we recommend an EVM chain — Polygon, Base, or Arbitrum for low fees, Ethereum mainnet where settlement assurance matters more than cost. Mtoag makes a recommendation during scoping based on your transaction volume, value at risk, and where your users already hold assets.

Internally, always — static analysis, invariant testing, and fuzzing are part of every build. We also coordinate an independent third-party audit before mainnet and remediate every finding. We do not consider a contract shippable on our internal review alone.

This is why the upgrade strategy is decided at architecture stage, not after launch. Where the use case allows, we deploy behind a proxy with multi-sig-controlled upgrades and a timelock; where immutability is the point, we build in pause and withdrawal escape hatches instead. Both approaches are documented in your Technical Specification.

Yes. Every function is gas-profiled during development and the results are reviewed at each sprint, so cost regressions get caught before deployment rather than being discovered by users paying for them.

Yes, and we prefer to. The frontend is where most user-facing dApp failures actually happen — unclear transaction previews, unhandled rejection states, silent nonce errors. Building both sides in one team removes the gap where those bugs live.

Yes, 100%. Source code and all intellectual property transfer to you on final payment, and contract ownership and deployer keys are handed over at launch through a documented process. No vendor lock-in.

Yes. We integrate regulated on-ramp providers and, where appropriate, account abstraction wallets, so users can sign up with an email address and pay by card without ever handling a seed phrase.

We build to the compliance position your legal advisers set — KYC gating, transfer restrictions, jurisdiction blocking, and record-keeping hooks are all implementable. Mtoag provides the engineering; we do not provide legal or financial advice on token classification.
