Overview

Gas costs affect adoption, especially on Ethereum mainnet. Gas optimisation combines contract-level improvements with system-level strategies: batching operations, using signatures for off-chain approvals, choosing efficient token standards, moving activity to Layer 2 networks and sponsoring gas through account abstraction. We measure costs per user action and reduce the ones that matter most.

Common use cases

  • User cost reductionCheaper mints, swaps and transfers.
  • Protocol operationsLower keeper and admin costs.
  • L2 migrationMoving activity to lower-cost networks.
  • Gasless UXSponsored transactions for users.

Quick answers

Gas Optimization at a glance

The essentials in brief. Every project is scoped individually — ask us for specifics.

What is gas optimization?
Reduce transaction costs for users with targeted gas optimisation, batching and L2 deployment strategies.
Who is it for?
Typically Web3 startups, fintechs adding digital assets, and institutions exploring tokenization, stablecoins or on-chain settlement.
What does Shivacha provide?
  • Cost analysis
  • Contract optimisation
  • Batching
  • Signature-based flows
  • Account abstraction
  • Network strategy
Which technologies are used?
Solidity, Foundry, ERC-4337, Arbitrum, Base, Vyper — chosen to fit your stack and constraints.
How does the process work?
Specify → Design → Implement → Test adversarially → Prepare for audit.
What affects the cost?
  • Contract complexity and number of chains
  • Custody and wallet model
  • Independent audit scope
  • Indexing, analytics and back-office tooling
  • Compliance integrations (KYC, AML, Travel Rule)
  • Upgradeability and governance requirements
How long does it take?
A focused contract system or dApp MVP typically takes 8–14 weeks plus independent audit time; institutional platforms usually take 4–9 months.
How do I get started?

Architecture

Engineered right from day one

The layers we typically design for smart contract engineering, adapted to your stack and partners.

  • Audit-ready, not self-auditedInternal review supports but never replaces independent audits.
  • Admin key designMultisig, timelocks and role separation for privileged functions.
  • Upgradeability trade-offsProxies add flexibility and risk; used only when justified.
  • Gas efficiencyOptimised where it matters, never at the expense of clarity or safety.

Delivery

How an engagement runs

  1. 1

    Specify

    Written specification with invariants, roles and failure modes.

  2. 2

    Design

    Contract architecture, storage layout, upgrade and admin model.

  3. 3

    Implement

    Minimal, readable code using well-reviewed libraries.

  4. 4

    Test adversarially

    Fuzzing, invariant tests, fork tests against real protocols and static analysis.

  5. 5

    Prepare for audit

    Documentation, coverage reports and a known-issues list for independent auditors.

Security

Security built into delivery

Controls we apply by default on this kind of work — not a separate phase at the end.

Specification first

Roles, invariants and threat model documented before code.

Adversarial testing

Fuzz, invariant and fork tests plus static analysis on every change.

Key management

Admin keys in multisig or MPC with timelocks on sensitive actions.

Independent audit

Code prepared for — and we recommend — an external audit before mainnet value.

FAQ

Frequently asked questions

What is the biggest gas saving usually?

Often architectural — moving to an L2, batching or reducing storage writes — rather than micro-optimisations.

Can users transact without holding gas tokens?

Yes, with paymasters and relayers under account abstraction.

What does audit-ready mean?

It means the contracts arrive at an independent audit with a clear specification, comprehensive tests including fuzz and invariant tests, static analysis resolved, documented trust assumptions and deployment plans — so auditors spend their time on deep issues.

Which languages do you use?

Solidity for EVM networks, with Vyper where appropriate, and Rust for Solana and other Rust-based environments.
