Paris Solutions

Best Blockchain and Web3 applications company in Paris

Wallet journeys and smart contracts connected to the CRM and operations systems behind them. Hosn Al Tomoh works with organisations in Paris on Web3 applications, agreeing scope, responsibilities and proof of completion for each phase from the start.

Web3 applications put wallets, digital ownership and smart contracts in front of investors or guests. The work covers the user journey, contract security and the link back to CRM and operations, so on-chain activity matches the business record.

We work with clients across the Middle East and beyond. For organisations in Paris, that usually means a programme with a Gulf footprint: we plan for your home-market data protection rules and for the GCC laws, such as the UAE and Saudi personal data protection laws, that apply where systems and data will sit.

Before go-live, we run a full rehearsal of the cutover with the team who will operate the service, and agree in advance how problems will be escalated in the first weeks after launch.

Where you already work with systems integrators or vendors, we can deliver in partnership with them, with each party's responsibilities written into the contract.

Where the effort goes

We concentrate on the points below, because that is where the work usually stumbles.

  • Wallet journeys that a first-time user can complete.
  • Smart contracts reviewed and tested before deployment, with an upgrade plan.
  • On-chain events reconciled with CRM and finance records.

Where programmes go wrong

Smart contracts are hard to change once deployed. We review the contract logic, test it thoroughly and agree how fixes will be handled before anything goes live.

We record decisions, responsibilities and test results as we go, so internal audit and regulators can trace every decision and who approved it.
