Launch Your Own Cosmos SDK Chain

Most teams don't fail at building an app-chain because the technology is missing. They fail because launching a sovereign chain is a full-stack problem that touches consensus, economics, infrastructure, and governance at the same time — and very few engineering teams have shipped all of it before. Vitwit has.

/ why cosmos sdk

Sovereignty without isolation

Instead of renting block space on a shared L1, you get your own chain: your own validator set, fee token, governance, and full control over the state machine. CometBFT handles consensus, giving you instant finality and predictable block times.

You own
  • Your validator set
  • Your fee token & economics
  • Your governance
  • Your state machine logic
  • Your upgrade path
Connected via IBC
  • Cosmos Hub
  • Osmosis & DeFi ecosystem
  • Ethereum via bridges
  • Every IBC-enabled chain
  • Cross-chain messages & assets

The trade you're making is sovereignty for responsibility. You own the throughput and the upgrade path — but also the security, validator economics, and operational burden.

This tradeoff makes sense for DeFi venues, RWA settlement layers, DePIN networks, and gaming chains that need custom logic at the protocol layer. And because every Cosmos chain speaks IBC, sovereignty doesn't mean isolation — your chain can move assets and messages to hundreds of other chains from day one.

/ what it takes

A production launch is more than a single command

The work breaks into layers, and each one has failure modes that only show up under real load.

01

State machine & modules

The SDK ships with battle-tested modules for staking, governance, bank, and authz. Your value lives in custom modules. Designing module boundaries, keeper interfaces, and message types correctly from the start saves painful migrations later.

  • Custom module architecture
  • Keeper & message type design
  • Audit-ready from commit one
02

Tokenomics & genesis

Inflation schedule, staking rewards, community pool, fee handling, initial allocations, vesting — encoded in genesis and in module parameters. Getting these wrong is expensive to fix once mainnet is live. They need to be modeled, not guessed.

  • Inflation & reward modeling
  • Vesting & allocation design
  • Parameter simulation
03

Consensus & validator set

Choosing validator set size, slashing parameters, unbonding periods, and minimum self-bond. Recruiting and coordinating a genesis validator set that is decentralized enough to be credible from block one.

  • Slashing & unbonding design
  • Genesis validator coordination
  • Decentralization from day one
04

Interoperability

IBC client, connection, and channel setup. Relayer configuration and operation. If your chain needs to talk to the Hub, Osmosis, or Ethereum via a bridge, that path has to be designed and tested — not bolted on after launch.

  • IBC client & channel setup
  • Relayer configuration
  • Bridge design & testing
05

Infrastructure

Sentry node topology, monitoring, alerting, key management, upgrade tooling, and explorers. The chain that runs cleanly in a devnet and falls over in production is almost always an infrastructure failure, not a code failure.

  • Sentry node topology
  • Monitoring & alerting stack
  • Upgrade tooling & explorers
/ how we run a launch

Staged delivery, not a single handoff

Security runs through all of it. State machine bugs are consensus bugs, and a consensus bug on a sovereign chain halts the network. We design for that reality from the first commit and bring chains to an audit-ready state rather than treating review as an afterthought.

A launch doesn't end at genesis — it ends after the third upgrade has gone cleanly and the relayers have stayed up through a network split. We're built to be there for that part, not just the launch announcement.

ArchitectureState machine design, module list, token model, and interoperability requirements — before a line of custom code is written.
02
Build & unit-testCustom module development, message handlers, genesis config, and full unit-test coverage.
03
DevnetEnd-to-end integration testing of the full system. Shake out cross-module interactions and infrastructure assumptions before anyone else is involved.
04
Public testnetExternal validators stress the network. Real governance proposals, real upgrades, real IBC. Everything that can go wrong tends to go wrong here, where it's cheap to fix.
05
Genesis ceremonyValidator onboarding, genesis file collection and verification, coordinated network start.
06
Mainnet launchMonitored launch with 24/7 coverage. Incident response procedures in place before the first block.
07
Post-launch operationsUpgrades, relayer maintenance, parameter governance, and ongoing infra support. A launch doesn't end at genesis.

Everything the chain needs after launch

A new chain needs validators, RPC endpoints, IBC relayers, and ongoing engineering support. Fragmenting that across vendors means no one owns the seams when something breaks at 3 a.m. on a network upgrade night.

We cover the full arc under one SLA and one on-call rotation — from the genesis ceremony to post-launch upgrades, IBC path setup, and managed endpoints for your ecosystem's wallets and dApps.

Seven years across the Cosmos ecosystem. Zero network halts.

We've written modules, run validators, and operated relayers across the Cosmos Hub, Akash, Regen, Cheqd, Passage3D, and Polygon. Architecture decisions informed by what actually breaks at 3 a.m. on mainnet — not by what looks clean in a diagram. If you're scoping an app-chain and want a partner who has shipped this before, let's talk through your architecture and where the real risks are.
