We build the web3products serious companiesput their name on.
Advisory, infrastructure, and product for companies building on-chain. Designed around ownership: built, audited, and handed over so your team runs all of it.
The shift is already happening.
Pick your field. The value has already moved on-chain — and the companies that own their rails are the ones capturing it.
$15T+ moved on stablecoins last year.
Card-network scale at a fraction of the cost — accept and settle in any token, on any chain, with no processor taking a cut.

What we build
Six domains, each engineered in-house and handed over.
Payments you control end to end
Authorization, capture, and settlement written into contracts you own — reversible by no one but you, and free of any processor's roadmap.
Explore →Custody that never leaves your hands
Keys generated and held on your hardware. Policy and multi-signature enforced in code we write with you and audit line by line.
Explore →Real-world assets, made legible and owned
Bring property, credit, art, and reserves on-chain with compliance and transfer rules enforced at the contract level — auditable from issuance to settlement.
Explore →Governance your stakeholders can trust
Voting, treasuries, and permissions encoded transparently, so every decision and every movement of funds is legible to the people accountable for them.
Explore →Settlement on your terms, not a counterparty's
Deterministic finality on the network and schedule you choose. Cross-border clearing without a clearinghouse sitting in the middle.
Explore →Treasury that runs itself
Programmatic float, sweeps, and yield — managed on-chain, owned outright, never rate-limited by a service you don't control.
Explore →Selected work.
Anonymized at our clients’ request — every engagement is under NDA. The shape is real; nothing here is inflated.
Supplier payouts that clear in one transaction.
The weekly supplier and partner run went out as hundreds of separate wires — days of float, per-wire fees, and a reconciliation headache at the end of every cycle.
- A batch settlement contract on a network they operate
- An payout pipeline with on-chain
- Reconciliation that reads straight from the chain
The whole run now settles as a single atomic transaction in seconds instead of days, with no intermediary in the flow — built, audited, and handed over.
Treasury the fund owns outright, working every hour.
Reserves sat idle off-hours, and yield strategies lived in a managed account the team couldn't fully control or audit.
- Policy-driven allocation across operating, reserve and yield
- — every action against keys the fund holds
- Isolated, opt-in yield with a full on-chain trail
Float is now allocated by rules the fund sets and can read, settling any hour, with nothing custody-critical leaving their environment.
Private credit, with the rules inside the contract.
They needed to issue and transfer tokenized private credit with compliance actually enforced — not promised in a side letter.
- A permissioned token with transfer restrictions enforced on-chain
- Conditional escrow with and defined recovery paths
- Issuance and redemption that are provable end to end
Only eligible holders can ever receive the asset, funds release only when conditions are met, and every step is auditable — with compliance still theirs to operate.
Payments that settle on-chain — and stay confidential.
They needed on-chain settlement without broadcasting every amount and counterparty to the world — confidentiality for the business, provability for the auditor.
- Shielded transfer contracts with zero-knowledge proofs of validity
- A privacy vault that holds balances confidentially, spendable only by the owner
- Selective disclosure — prove a payment to an auditor without revealing the rest
Counterparties and amounts stay private by default; validity and solvency stay provable on demand — non-custodial throughout.
One stack: a wallet that's also a PSP, a vault, and a subscription engine.
They wanted to own the whole consumer stack — wallet, acceptance, confidential storage and subscriptions — instead of stitching four vendors who each hold a piece, and the keys.
- A self-custodial wallet: keys on the user's device, recovery paths defined
- A PSP rail: authorize, capture and settle, in contracts they own
- A privacy vault for confidential balances and statements
- Recurring on-chain billing with revocable, inspectable authorizations
Every layer is theirs and non-custodial — the user holds the keys, the business holds the contracts, and no vendor sits in the middle of any of it.
Compliance checks without the data lake.
They were obligated to verify users but didn't want to become a honeypot of personal data that every regulator and attacker would come for.
- Zero-knowledge eligibility proofs — verify a claim without seeing the data behind it
- Attestations issued once and reusable across the platform
- Nothing personal stored on-chain or by us — the user keeps their data
Eligibility is provable on every transaction; the personal data never leaves the user, so there is no lake to leak.
Settle across currencies without a correspondent bank.
Moving value between currencies meant correspondent banks, pre-funded accounts, and days of settlement risk on every leg.
- On-chain FX between regulated local stablecoins
- swap-and-settle — the trade and the transfer are one transaction
- Pricing and limits enforced in contracts they operate
Cross-currency value moves and settles atomically in seconds, with no correspondent bank holding the float in the middle.
Cards that spend self-custodial balances.
Card programs normally pool user funds in a custodial account — the user gives up their keys just to spend with a card.
- On-chain authorization: each card auth checks and locks funds in a contract the user controls
- Self-custodial balances — keys stay with the user, not the program
- Settlement to the network with a full, provable trail
Users spend with a card while keeping their keys; the program never takes custody, and every authorization is provable on-chain.
Real assets, made liquid.
From private credit to carbon — brought on-chain with ownership, yield, and provenance enforced in the contract, not a custodian.
↓ Scroll — each asset class slides over the lastPrivate credit
Loans originated, serviced, and traded as tokens — the largest asset class already moving on-chain.
Treasuries & bonds
Tokenized T-bills and sovereign debt — yield that settles on-chain, around the clock.
Real estate
Title, rent, and equity — tokenized, divisible, and transferable.
Fine art
Provenance and fractional ownership of blue-chip works, enforced on-chain.
Trade finance
Invoices and receivables, financed and settled without the paperwork.
Carbon credits
Verifiable environmental credits, retired transparently on-chain.
Seven primitives, all written in-house.
Payments, settlement, custody, treasury, subscriptions, vaulting and escrow, tokenization — each built from scratch, audited, and handed over. No black boxes, no rented rails.
Open any one for the deep dive — how it works, what you own, and where teams get it wrong.
Authorization, capture, and settlement logic you control — reversible by no one but you. On-chain enforcement, off the vendor's roadmap.
Released when the payer marks the work delivered.
Illustrative flow. The contract, conditions, and recovery paths are written for your case and handed over.
Escrow that answers only to your rules.
Funds held in a contract you own and can read — released the moment your conditions are met, and never before. Time-locks, delivery checks, multi-party approval: defined by you, enforced on-chain.
- Conditional release, written to your spec
- Time-locks and recovery paths you define
- Non-custodial — no third party can touch it
Security is the whole job.
In crypto, one mistake is terminal. We build as if every line will be attacked — because it will be.
Threat-modeled first
We map how a system breaks before we decide how it works.
Audited twice
Internal review plus an independent third-party audit, with your engineers reading along.
Keys stay yours
Nothing custody-critical ever leaves your environment.
Full trail at handoff
Repository, runbook, and audit reports — every decision is provable.
What you own at handoff.
Every engagement ends with you holding the whole thing — nothing rented, nothing locked.
The repository
Every line of the system, in your version control.
A runbook
How to operate, deploy, and recover — written for your team.
Audit reports
Internal review and an independent third-party audit.
Your team, trained
We hand over knowledge, not just code.
Whatever your product needs on-chain.
Below is one example — a payment flow across any chain and token, one-off or recurring. Whatever the on-chain logic your product calls for, we build it, audit it, and hand it over.
- One-off or recurring — any flow
- Any token, any chain — EVM and Solana
- Built and handed over — you own it
One-off or recurring · any token, any chain · non-custodial
Live FX over public APIs. Request, address and QR generated client-side — no funds move.
Settlement measured in seconds — not days.
Illustrative batch. The contracts and networks are chosen and built for your case, then handed over.
A whole payout run. One transaction.
Payroll, suppliers, fund distributions — an entire batch clears atomically in seconds, not a week of wires sent one at a time. One example below.
- Hundreds of payments, one atomic settlement
- Final in seconds, not days
- No intermediary, no per-wire drag
Float that works every hour you hold it.
Treasury that runs itself.
Float, reserves, and yield — allocated by rules you set, settling any hour, never rate-limited by a service you don't run. One example below.
- Programmatic allocation and sweeps
- Yield on idle reserves, opt-in
- Owned outright — 24/7, non-custodial
Illustrative allocation. Strategies, limits, and custody are written to your spec and handed over.
Own your infrastructure. Don't rent it.
Custody you don't control isn't custody.
If you can't read the contract, you don't own the system.
Build it to be handed over — the engagement should end.
On-chain, or it didn't happen.
How an engagement runs.
Four phases. You're in the room for all of them, and you leave owning everything.
We pressure-test the idea
Before a line of code, we map the mechanism, the threat model, and what ownership has to look like at the end.
We engineer in your environment
Product and contracts develop together, on your infrastructure, under your keys.
We prove it, line by line
Internal review plus a third-party audit, with your engineers reading along — not after the fact.
We hand over the keys and leave
Repository, runbook, and audit transferred. No retainer, no lock-in. The engagement ends.
Built with you. Handed to you.
Tell us what you're bringing on-chain. We scope it, build it, audit it, and hand it over — keys, code, and all.
- Non-custodial by default
- Built, audited, and handed over
- NDA on request
