/// Services / Blockchain

Blockchain infrastructure, audited and built to last.

Smart contracts, wallets, custody, and tokenization — gas-aware, security-reviewed, and designed for the day after launch. We build the on-chain rails and the off-chain systems that keep them honest.

/// How we approach it

Security is the feature.

On-chain code is permanent and public — a bug is a headline. We design for the worst case: threat-modelled contracts, exhaustive tests, external audits, and upgrade paths that don't hand anyone the keys. Then we build the indexers, dashboards, and custody around them.

  • [ 01 ]Threat model and invariants before implementation
  • [ 02 ]Gas-aware, upgrade-safe contract design
  • [ 03 ]External audit and continuous fuzzing
  • [ 04 ]Custody and key management done properly
/// Capabilities

/// In the field
Six gates before mainnet: audit closed with 0 critical findings, 34/34 invariants, 12.4M fuzz runs. Promotion stays locked until the second signer approves.
2,400,000 units across 142 holders, every transfer policy-checked on-chain — 37/37 cleared in 30 days, lock-ups and the 9.9% holder cap enforced by the contract.
A 33,600-unit cold-vault transfer waits on the second of three signers — destination whitelisted, quorum at 1 of 2, signed on-device before anything moves.
Batch SB-2071 mid-flight: 12/12 confirmations done, bridge attestation at 2/3, SEPA Instant payout queued. €1,284,300 settled today, 0 manual touches.
The consent sheet a host app embeds: verified domain, read-only by default, every transfer signed in the wallet — keys never leave the device.
/// How we work

From spec to settled on-chain.

  1. [ 01 ]

    Model

    We map the assets, actors, and invariants — and the attacks each one invites.

  2. [ 02 ]

    Build

    Contracts and off-chain services in tight increments, tested against the invariants.

  3. [ 03 ]

    Audit

    External review, fuzzing, and a public testnet before a single real asset moves.

  4. [ 04 ]

    Operate

    Monitoring, incident runbooks, and custody you can trust — handed over or run with you.

On-chain

On-chain settlement that ends in an IBAN

External wallet connect, on-chain settlement bridged to an IBAN in one flow, multi-chain treasury behind 2-of-3 signers.

All major chains, one flowView case
Custody

A cold vault with time on your side

Self-custody with 24h time-locked withdrawals, 2-of-3 guardian approvals, and whitelisted addresses.

Three locks an attacker must beatView case
