Our commitment

Web3 should be invisible to the user

The big Web3 failure of 2021-2022 was catastrophic UX: wallets to configure, incomprehensible gas fees, anxiety-inducing signatures. The projects that survived are the ones that made blockchain invisible.

At Inprogress, we've integrated crypto wallets into several apps in production. Our priority: Web3 must bring value without ever blocking the user on a technical concept they don't understand.

Our responsibility

Web3 that holds in production and compliance

Poorly audited smart contracts, lost private keys, evolving crypto regulation (MiCA is coming): Web3 in production is full of traps that artisanal development doesn't see coming.

We work with specialized smart contract auditors, anticipate MiCA compliance for the European market, and design wallets with recovery and integrated KYC when the use case requires it.

Why Inprogress?

Product arbitrations

We help you decide between features requested by customers and those that move the strategic roadmap forward.

Enterprise-grade security

Multi-tenant isolation, audit logs, SSO, GDPR compliance: the product is ready for your most demanding B2B sales cycles.

Delivery speed

Short sprints, regular releases, observability in place: the product moves forward continuously without breaking production.

Frequently asked questions

Multi-tenancy (strict data isolation between clients), complex billing (plans, add-ons, prorata, upgrades), SSO and granular permissions, stable and versioned public APIs.

Each of these is addressed seriously from scoping, not improvised along the way.

We pick the isolation model that fits your context: shared schema, schema per tenant or database per tenant. Each approach has trade-offs on cost, performance and isolation.

For most early-stage B2B SaaS, shared schema with properly configured row-level security is the right balance.

One to two week sprints, continuous production releases, feature flags to test with select customers before general rollout.

The product team keeps a sustainable pace and your first customers see added value every sprint.

Ethereum, Polygon, Solana are most common. Arbitrum, Base, Optimism for Ethereum L2s. We help you decide based on your constraints (gas fees, ecosystem, geographic targeting).

Blockchain choice is a product decision as much as a technical one: it impacts UX, costs, community.

Non-custodial (user manages keys) = maximum sovereignty but UX friction and key loss risk. Custodial (you manage keys) = smooth UX but technical and regulatory responsibility.

For mainstream audiences, hybrid solutions (custodial with migration option) often give the best compromise.

We integrate crypto-specialized KYC partners (Sumsub, Veriff) and prepare architectures for MiCA (PSAN registration, transaction traceability, key governance).

Crypto compliance evolves fast: we stay in active watch and adapt projects as regulations evolve.
