Services
Three practices with concrete deliverables. If your problem sits between two of them, that is usually the interesting part.
01Chain
For protocol and product teams who need contracts, oracles and wallet flows that survive audit, adversarial users and real money.
Escrow, payout, staking and access contracts written to be read by an auditor, with the failure cases tested before the happy path is celebrated.
Signed data feeds, scoring oracles and proof systems that let a contract accept an off-chain fact without trusting the messenger.
Wallet authentication, transaction lifecycle and ledger views built so a user always knows what state their money is in.

PvPserver-authoritative matches
A decentralised credit scoring oracle on Base that turns off-chain verification signals into signed, on-chain reputation.
EIP-712signed oracle updates
A multi-chain launchpad for tokens and NFT drops that ships either as the unified platform or as a single-chain white-label product, from one codebase.

02Product
For founders and operators turning a validated idea into a multi-tenant product with billing, roles and a data model that still works at the tenth customer.
Tenant isolation at the database layer, plan tiers with real quota enforcement, and an admin surface the operator can actually run the business from.
One product core reaching both stores, with a native shell only where the device capability actually requires it.
Fast, art-directed sites that carry a real position instead of a template, and stay editable by the people who own the brand.

03Automation
For teams that want language models doing real work: grounded generation, message automation and data pipelines with guardrails, queues and audit trails.
Retrieval-grounded generation with evaluation, fallbacks and cost control, so the feature keeps working when a provider does not.
Bots and scheduled jobs that carry real business state: queues, retries, rate limits and an audit trail for every action taken on a user account.
Collection, normalisation and scoring pipelines that turn noisy external sources into a store you can query with confidence.
