Capabilities Blockchain

dApp development and blockchain infrastructure engineering.

Deep blockchain expertise, having built and invested across many DeFi categories. Experience on every major Layer 1 and Layer 2, and a long history of contributing critical on-chain utilities and infrastructure.

The gap

On-chain engineering
is unforgiving.

A contract bug is irreversible, an exploit is public, and the testing discipline that most software can defer has to be there before launch. Engineers who have actually shipped production systems on-chain, and kept them running under real value, are rare. That is the team we bring, across every major chain, with the patterns below recurring in the work.

Patterns we bring

Repeatable across on-chain engagements, not one-off.

Smart contracts, tested like they are irreversible

Contract development across EVM and Solidity, Stellar and Soroban, Solana, Cosmos, and Move, with chain testing, migration, and audit-grade QA discipline.

Wallets and account abstraction

Wallet and custody infrastructure, embedded wallets, and account abstraction, the entry point of every on-chain product.

Stablecoins, payments, and cards

Issuance, settlement, reconciliation, and card infrastructure at network scale, engineered for the volumes where most systems break.

On-chain credit and RWA

Receivables financing, private credit, tokenized real-world assets, and the collateral management underneath them.

On-chain AI agents

Agents for trading, yield and liquidity, compliance, and contract auditing, with guardrails engineered for irreversible environments.

Cross-chain and interoperability

Bridging, intents-based systems, and multi-chain compatibility, so a protocol is not trapped on its first chain.

Ecosystems

Deep in three, fluent across the rest.

Stellar

Stellar

A preferred engineering partner in the Stellar ecosystem: Soroban smart contracts, wallets, and developer tooling for teams building on the network.

Canton

Canton

Privacy-preserving infrastructure in the Canton and Daml ecosystem, where institutional finance meets on-chain settlement.

EVM

EVM

The broadest surface: Solidity contracts, account abstraction, DeFi protocols, and migration work across Ethereum and EVM-compatible chains.

How we engage

Scoped or sustained.

A Blueprint scopes the contract or infrastructure layer and proves it. An engineering subscription carries sustained protocol work at a fixed fee with quality gates.
