Most Web3 systems don't struggle on the contract — they struggle around it: indexing pipelines that fall behind, RPC bills that scale faster than users, settlement books that never quite reconcile with the chain, and wallet flows users abandon. Beneventa Tech designs that layer. Your team, your vendors and your licensed partners build and operate it.
Design review of on-chain/off-chain boundaries: what belongs in contracts, what belongs in services, upgrade and governance mechanics, degradation behaviour under load.
Self-hosted vs managed node strategy, provider redundancy, rate-limit and cost engineering, archive vs full-node planning across the chains you target.
Event ingestion, reorg handling, backfill strategy, subgraph vs custom indexer trade-offs, serving layers for product and analytics.
Integration architecture with your licensed custodian or wallet vendor: MPC vs multisig vs HSM trade-offs, signing workflows, key rotation and recovery procedures as operational process design.
Architecture for client-operated settlement flows: ledger design, reconciliation between on-chain events and internal books, idempotency, chain-selection criteria. Operated by you and your licensed payment partners — never by us.
Reporting design that ties on-chain transactions to business records: reconciliation trails, proof-of-reserve-style statements, dashboards your finance team and external accountants can rely on.
Smart-account architecture: ERC-4337 stacks, paymasters and gas sponsorship, session keys, social recovery flows — so users stop seeing seed phrases and failed transactions.
Rollup and appchain selection, bridge and messaging architecture, liquidity and state fragmentation trade-offs, chain-abstraction patterns for multi-chain products.
Delivery process design: testing and simulation strategy on forked networks, release and upgrade management, dependency and library policy, documentation your next hire can onboard with.
On-chain analytics with ML, anomaly and pattern detection on transaction streams for product insight, LLM-assisted monitoring and support, agent infrastructure that reads chain state reliably.
Illustrative. Dashed green nodes are run by the client or the client's licensed providers; solid nodes are systems we help the client's engineers design and build. Beneventa Tech appears nowhere in the runtime path.

The pattern behind W1.3 and W1.10: one ingestion spine feeding product features, dashboards and ML.
Every engagement produces a filled-in version of this matrix with reasoning per row. Options listed are examples, not endorsements.
| Layer | Typical options | What actually decides it |
|---|---|---|
| Execution | Ethereum L1 · OP-stack / Arbitrum rollups · Solana · appchains | Finality needs, fee tolerance, ecosystem of the users you already have |
| Node access | Self-hosted · managed RPC · hybrid with failover | Request volume and shape, archive needs, ops headcount, unit cost at 10× scale |
| Indexing | Subgraphs · custom indexer · vendor firehose | Query patterns, reorg sensitivity, backfill volume, schema ownership |
| Wallets / accounts | EOA + vendor wallet · MPC custodian · ERC-4337 smart accounts | Who your users are, regulatory posture of your licensed partners, recovery UX |
| Settlement asset | USD-backed stablecoins on the chains above | Issuer support per chain, your PSP's coverage, treasury policy set by the client |
| Data & ML | Lakehouse + streaming · vendor analytics · in-product models | Latency of the decisions the data feeds, team skill set, cost per query |
| Model | Shape | Typical output | Fits when |
|---|---|---|---|
| Architecture sprint | 2–4 weeks, fixed scope | Findings memo, target architecture, decision records | You need a design or a second opinion before committing budget. |
| Design partner | Monthly retainer | Ongoing designs, reviews of your team's RFCs, vendor evaluations | You're building continuously and want an architect on call. |
| Migration programme | Scoped multi-month project | Transition architecture, cutover plan, vendor shortlists, cost model | You're moving chains, changing custody vendors, or rebuilding indexing at scale. |
Clear boundaries make the advisory useful. These are scoped out of every engagement:
We never hold, generate or have access to client or end-user private keys, seed phrases or funds — in production or in test.
We don't design tokenomics, run token sales, or advise on issuing, listing or marketing any token.
No market-making, treasury trading strategies, staking-as-a-service or yield products — and no advice on them.
Settlement systems we design are operated by clients and their licensed providers. We are not a payment institution and don't act as one.
