137 is an MVP development studio for Web3 founders, positioned around “fixed scope, fixed price, fixed timeline.” It is not a traditional developer SaaS tool, but a project-based engineering service that helps early-stage teams deliver a testnet prototype, audit-ready mainnet code, or a fundraising-ready build within 4 to 8 weeks.
Based on the main copy, 137’s key deliverables include wallets, authentication, smart contracts, front ends, testing, deployment scripts, tokens, multi-chain support, and third-party integrations. It emphasizes the team’s experience across DeFi, wallets, banking, iGaming, healthcare compliance, and encrypted file exchange, positioning itself as a specialist team that can avoid the Web3 security pitfalls often seen in AI-generated code or general-purpose agencies. A full supported tech stack is not listed, but the site mentions scenarios involving Solidity, Solana program, ERC-3643, L2, RPC, indexers, oracles, KYC, cross-chain messaging, and bridges.
Pricing is disclosed fairly clearly: 4 weeks for €19,000 to deliver a testnet prototype; 6 weeks for €39,000 to deliver audit-ready code, front end, contracts, tests, and deployment scripts; and 8 weeks for €79,000 covering tokens, front end, integrations, and multi-chain support for teams preparing for a funding round. External audit fees are not included, with the article citing a typical range of €10k–€30k. Mainnet gas fees and third-party services such as RPC, indexers, and oracles are also billed separately. 137 promises that if it underestimates the scope, it will absorb the overrun, and it includes 30 days of post-launch defect support.
The main advantages are that pricing, timeline, scope, and exclusions are stated relatively directly, and the fixed-price model helps early teams keep budgets under control. It also shows awareness of common Web3 risks such as contract security, audit readiness, MEV, and frontrunning protection. The drawbacks are the lack of details on company location, team size, payment methods, exact tech stack, open-source code, or technical documentation. It is also not a good fit for highly uncertain research-driven projects, such as a new L1, complex ZK circuits, or product exploration where the requirements are not yet clearly defined.
137 is best suited to Web3 founders who already have a clear product scope, fundraising milestone, or launch window, especially teams working on DeFi, on-chain payments, wallets, game settlement, or tokenized products. The source text does not provide information on access from China, and payment methods are not disclosed, so these should be marked as unknown. Teams in China would need to verify network accessibility, euro payments, invoicing, contracting entity, and compliance requirements. Alternatives include hiring Solidity contractors, building an in-house engineering team, choosing a traditional Web3 agency, or sourcing development services recommended by audit firms on a case-by-case basis.
