We build the tooling, wallets, and infrastructure behind Accumulate.

Kompendium is a software studio and the primary engineering team behind OpenDLT — authors of Accumulate’s mobile wallet, core developer tooling, and validator infrastructure, and a standing member of network governance.

[ 01 · the flagship ]

Deep in the Accumulate stack.

We aren’t adjacent to Accumulate — we help build and run it. From the wallet in users’ hands to the nodes validating the chain, our fingerprints are across the network.

Kompendium sits at the center of the work that keeps Accumulate running — hover any node to see how.

WalletACCU2 — mobile signing for Accumulate

We designed and built Accumulate’s mobile wallet end to end: zero-friction identity onboarding, multi-sig approvals, and push-notified delegated signing on iOS and Android.

CoreCore development & tooling

We are a primary author of Accumulate’s developer tooling — the libraries, SDKs, and utilities that other teams build on — and contribute directly to core protocol development.

RunValidator & bridge infrastructure

We operate a validator node and a bridge node on the network, helping secure consensus and move value between chains with production-grade reliability.

[ 02 · capabilities ]

What we build.

One team across the full stack of decentralized software — from the contract layer to the app in your pocket to the node under the network.

Custom software development

Tailored, cost-effective systems built to production standards — web, mobile, and backend.

Smart contract development

Efficient, audited, purpose-built contracts — secure logic for real economic weight.

Crypto wallets

Wallets and exchange integrations with clear provenance and safe, legible approvals.

dApps & deployment

Decentralized apps shipped and operated — from identity to on-chain interaction.

Node & validator ops

Validator and bridge infrastructure operated for uptime, security, and network health.

Developer tooling

Libraries and SDKs that make building on-chain faster, safer, and more legible.
