    Frequently Asked Questions

    Multi-Party Computation (MPC) wallets split a single private key into shards held by separate parties so no individual ever sees the full key. Compared to multisig, MPC produces a single on-chain signature (cheaper, more private) and works across chains that don't support native multisig. Enterprises use them because they meet institutional custody requirements (no single point of compromise), support flexible policy controls (approval thresholds, time locks), and integrate with HSMs for additional protection.

    Use public chains (Ethereum, Solana, Bitcoin) when the value comes from interoperability, transparency, or composability with existing DeFi/NFT infrastructure. Use permissioned chains (Hyperledger Fabric, Corda) when regulatory requirements demand identifiable participants, data privacy, or strict throughput guarantees. For most enterprise use cases the practical answer is a hybrid: a private subnet or rollup that anchors proofs to a public chain.

    Our process: peer review with two senior smart-contract engineers, automated analysis (Slither, Mythril, Echidna for fuzz testing), formal verification of critical invariants where feasible, third-party audit by a recognized firm, public testnet deployment with bug bounty, then phased mainnet rollout with circuit breakers and time-locked upgrades. We never deploy unaudited code to mainnet — period.

    The honest answer: most 'blockchain' use cases are better served by a database. The legitimate enterprise applications in 2026 are (1) stablecoin payments and treasury for cross-border B2B settlement, (2) tokenized real-world assets (RWA) for fractional ownership and 24/7 settlement, (3) supply chain provenance where multi-party trust is needed, and (4) regulated digital identity. Skip the rest.

    Both. We pick based on the use case: Ethereum and its L2s (Arbitrum, Optimism, Base) for high-value financial applications where decentralization and tooling maturity matter most. Solana for high-throughput, low-fee consumer applications where transaction speed dominates. We also work on Polygon, Avalanche, and Hyperledger Fabric for enterprise permissioned use cases.
