Custom module development
Build application-specific Cosmos SDK modules with explicit state transitions, message handling, and invariant checks written in Go.
Cosmos SDK Development
Cosmos SDK appchain development — custom modules, IBC integration, and validator operations for teams that need chain-level control a smart contract can't give them.
Book a discovery callTHE BUSINESS NEED
Some products need control that a smart contract on someone else's chain can't offer — custom gas economics, application-specific consensus rules, or direct control over block production. Cosmos SDK makes building an application-specific blockchain realistic, but it requires genuine Go engineering and careful module design, not configuration of a template.
We start with the state machine your application actually needs — what changes, who can change it, and what invariants must hold — and build Cosmos SDK modules around that, using standard modules where they fit and custom ones only where the requirements demand it. CometBFT consensus configuration and validator setup are planned alongside the module design, not left until after development finishes.
CAPABILITY IN DETAIL
Specific engineering work, connected to a business need.
Build application-specific Cosmos SDK modules with explicit state transitions, message handling, and invariant checks written in Go.
Configure CometBFT consensus parameters, staking economics, and governance modules to match the network's intended validator and token model.
Implement Inter-Blockchain Communication support so the appchain can transfer assets and data with other IBC-enabled chains in the Cosmos ecosystem.
Document node setup, upgrade procedures, and monitoring so validators — internal or external — can run the network reliably after launch.
WHERE IT CAN HELP
Illustrative engagement types, not claims about previous projects.
BEFORE WE BEGIN
A smart contract runs within an existing chain's rules. An appchain built with Cosmos SDK is its own blockchain with its own consensus, gas model, and governance — appropriate when a project needs that level of control, not by default.
That depends on the network's decentralization goals. We can help plan a validator set, whether that means your own infrastructure, a partner network, or a mix.
No. It's justified when application-specific consensus or economics matter enough to outweigh the operational cost of running an independent chain. We discuss that trade-off honestly before recommending it.
