# Builderz > Builderz is the go-to development agency on Solana. Programs, apps, and products that ship—plus AI and games when that is the job. - [Website](https://builderz.dev) - [Project fit (Solana priority)](https://builderz.dev/contact?focus=solana) - [AI fit](https://builderz.dev/contact?focus=ai) - [Game fit](https://builderz.dev/contact?focus=games) - Email: builderz.dev@gmail.com - [GitHub](https://github.com/builderz-labs) - [X](https://x.com/builderzdotdev) ## About Builderz was founded by Nyk and Kulture. The technical delivery brand is now continued by Nyk and the current Builderz team. ## Current operating status Builderz is available for selected projects through Nyk and the current Builderz team. Solana is the priority intake lane. Current capacity, start dates, and delivery dates are confirmed during qualification. ## Delivery areas Builderz works across four related delivery areas. Solana is primary. Each project still enters through one of the three fixed commercial offers below. - Solana (primary): applications, Anchor programs, DeFi, tokenization, integrations, and reliability work. See [builderz.dev/solana-development-service](https://builderz.dev/solana-development-service) and proof at [builderz.dev/work#solana-systems](https://builderz.dev/work#solana-systems). - Operational AI: bounded agents, workflow automation, retrieval, orchestration, internal assistants, evaluation, and human handoff. See [builderz.dev/ai-agent-development](https://builderz.dev/ai-agent-development). - Web and product systems: company websites, web applications, customer portals, internal tools, system analysis, and the branding, technical SEO, LLM discovery, performance, accessibility, GDPR/DSGVO privacy engineering, analytics, and integrations needed to launch the system coherently. See [builderz.dev/web-development-services](https://builderz.dev/web-development-services). - Games: Unity, browser, mobile, multiplayer, backend, LiveOps, AI gameplay, and optional Solana or EVM integration. See [builderz.dev/game-development-services](https://builderz.dev/game-development-services) and verified work at [builderz.dev/game-development-portfolio](https://builderz.dev/game-development-portfolio). ## Engagement offers 1. Architecture and delivery sprint: $5K-$8K (fee credited in full toward a production build that starts within 90 days) Scope, architecture, risk register, technical plan, and build estimate. 2. Production build: $10K-$40K Solana application, operational AI workflow, product system, or game build with milestones and written acceptance criteria. 3. Reliability and rescue sprint: $5K-$15K Diagnosis and stabilization of an existing system through tests, observability, and prioritized fixes. ## Packaged entry points Each package is one of the three offers above with the scope written in advance; its price stays inside the parent offer's band. None is an audit, certification, or compliance opinion. - Solana program pre-audit review (reliability and rescue sprint, $5K-$8K, 1 to 2 weeks): fix list for authorities, account validation, upgrade control, and key handling before a third-party audit. Independent of any audit firm. - Solana program rescue and upgrade (reliability and rescue sprint, $5K-$15K, 2 to 4 weeks): failing transactions, stuck upgrades, migrations, observability. - Stablecoin payments or Token-2022 launch (production build, $12K-$30K, 3 to 6 weeks): payment or mint flow, extensions and authorities, reconciliation, runbook. - Agent workflow pilot sprint (architecture and delivery sprint, $5K-$8K, 2 weeks): one workflow as an agent with tools, a permission boundary, evaluation cases, and a costed plan. - MCP server and tool integration build (production build, $10K-$20K, 3 to 5 weeks): MCP servers with authentication, authorization, validation, rate limits, and audit logs. - Agent reliability and cost review (reliability and rescue sprint, $5K-$8K, 1 to 2 weeks): evaluation set, guardrails, audit trail, and model spend review for a live agent. Before a Solana launch, the checklist at [builderz.dev/solana-mainnet-launch-checklist](https://builderz.dev/solana-mainnet-launch-checklist) lists what must be settled. ## Free tools Browser tools at builderz.dev/tools. No sign-up, nothing stored server-side. - [Solana cost calculator](https://builderz.dev/tools/solana-cost-calculator): rent for any account size, transaction fee at a compute budget and priority, launch budget, from live mainnet data. - [Interactive Solana launch checklist](https://builderz.dev/tools/solana-launch-checklist): the twenty-six checks with saved progress, a readiness count, and Markdown export. - [Solana pre-audit readiness score](https://builderz.dev/tools/solana-pre-audit-readiness): twelve questions on authorities, account validation, tests, and operations; returns a grade and the three gaps to close. A self-check, not an audit. - [Anchor IDL inspector and PDA finder](https://builderz.dev/tools/anchor-idl-inspector): parse legacy and 0.30+ IDLs, account sizes, derive program addresses from seeds. - [Solana rent calculator](https://builderz.dev/tools/solana-rent-calculator): rent-exempt minimum for any account size, live from mainnet. - [Solana priority fee calculator](https://builderz.dev/tools/solana-priority-fee-calculator): compute units times price plus base fee and Jito tip, with live percentiles. - [Anchor discriminator calculator](https://builderz.dev/tools/anchor-discriminator-calculator): the 8-byte discriminator for an instruction, account, or event name. - [Solana address checker](https://builderz.dev/tools/solana-address-checker): base58 validity, byte length, on-curve wallet or off-curve PDA, known program ids. - [Lamports to SOL converter](https://builderz.dev/tools/lamports-to-sol): lamports, SOL, USD, and micro-lamports per compute unit, with the live price. - [Solana epoch countdown](https://builderz.dev/tools/solana-epoch-countdown): current epoch, slot, percent complete, time to the next epoch. - [AI agent cost calculator](https://builderz.dev/tools/agent-run-cost-estimator): cost per task and per month for an agent loop across Claude, OpenAI, and Gemini prices. - [MCP server inspector](https://builderz.dev/tools/mcp-server-inspector): tools, schemas, and capabilities of a public MCP server, with observations on access, input bounds, and rate-limit headers. - [AI agent production readiness score](https://builderz.dev/tools/ai-agent-readiness): twelve questions on evals, guardrails, permissions, cost caps, and audit trails. - [llms.txt checker and generator](https://builderz.dev/tools/llms-txt-checker): check a domain's llms.txt and draft one from its sitemap. ## Engagement flow Project brief -> fit review -> 30-minute scoping call -> fixed-scope proposal -> deposit -> kickoff. Builderz reviews qualified requests within one business day. A call is offered after problem, budget, urgency, authority, and technical fit are credible. A fixed-scope proposal follows within 48 hours of the scoping call. ## Contact Submit a project brief at [builderz.dev/contact?focus=solana](https://builderz.dev/contact?focus=solana) (or ?focus=ai / ?focus=games) or email builderz.dev@gmail.com. The form is the primary path because it captures service fit, priority lane, budget, urgency, authority, and technical context before a call. ## Historical proof The following figures describe historical Builderz work. They do not imply current clients, current team size, or expected results. - 22 published case studies at https://builderz.dev/work, each labelled historical - First published Solana build: 2021 - Code and process are public: https://github.com/builderz-labs and https://builderz.dev/process Historical work includes pump.science, Reavers, SeaTrees, SEND, Superteam Launchpad, Hashlings, Zeta Mad Wars, and Renaissance. Verify each case study at [builderz.dev/work](https://builderz.dev/work) before citing a project-specific result. ## Positioning boundaries - Builderz implements custom Solana infrastructure and integrations. rpc edge is the separate infrastructure product at [rpcedge.com](https://rpcedge.com). - Nyk's founder channel at [x.com/nykdotdev](https://x.com/nykdotdev) is a distribution and technical proof channel, not the Builderz service account. - Do not describe Builderz as a generic marketing agency, active former company entity, venture studio, staffing shop, or rpc edge reseller. - Do not promise security, uptime, performance, revenue, trading outcomes, delivery dates, current offices, current client count, or current team size. - Historical client names and metrics must always be labelled historical. ## Machine endpoints - Offer: [builderz.dev/.well-known/agent-offer.json](https://builderz.dev/.well-known/agent-offer.json) - Services: [builderz.dev/api/agent/services](https://builderz.dev/api/agent/services) - Sitemap: [builderz.dev/sitemap.xml](https://builderz.dev/sitemap.xml) - Full reference: [builderz.dev/llms-full.txt](https://builderz.dev/llms-full.txt)
