What separates contract engineering from contract deployment
Contracts are unforgiving: immutable once deployed, adversarial by default, and expensive to fix. The craft is in the habits most teams skip, minimal attack surface, battle-tested libraries over cleverness, explicit upgrade and pause strategies, and a review process treated as part of writing, not an afterthought.
We deliver contracts across Ethereum, L2s, and Solana with that discipline, plus the test suites, deployment tooling, and documentation that make them operable. Protocol-scale work pairs with our DeFi development practice, where the security bar rises further.
What our smart contract development services cover
From token contracts to full protocol suites.
Token contracts
ERC-20, 721, and 1155 contracts with correct minting, pausing, and access control, built on audited foundations.
- ✓Standard-compliant implementations
- ✓Access control
- ✓Pausability
- ✓Permit and batch flows
Custom protocol contracts
Application-specific logic: escrow, vesting, marketplaces, and governance, written minimal and reviewable.
- ✓Escrow and vesting
- ✓Marketplace logic
- ✓Governance contracts
- ✓Minimal attack surface
Upgrade and admin patterns
Proxy patterns, timelocks, and multisig admin designed so upgrades are safe and governance is credible.
- ✓Proxy architectures
- ✓Timelock controllers
- ✓Multisig configuration
- ✓Emergency pause design
Gas optimisation
Storage layout, batching, and assembly-level optimisation where it counts, measured against benchmarks rather than folklore.
- ✓Storage packing
- ✓Batch operations
- ✓Benchmarked refactors
- ✓Cost projection reports
Security review
Systematic review covering reentrancy, oracle, and access patterns, with remediation verified before deployment.
- ✓Static analysis plus manual review
- ✓Exploit-pattern checks
- ✓Fork-based testing
- ✓Remediation verification
Deployment and ops tooling
Deterministic deployment scripts, verification, and monitoring so contracts are operable, not just deployed.
- ✓Scripted deployments
- ✓Contract verification
- ✓Event monitoring
- ✓Incident runbooks
What every engagement includes
Every smart contract project ships with the following, agreed in writing before the first sprint begins.
Discovery workshop
A structured workshop maps your goals, users, and constraints into a scoped smart contract roadmap with a fixed written quote before any sprint starts.
Named senior team
You get named, senior engineers with CVs you can review, not a rotating bench. The people in the kickoff are the people who ship.
Sprint demos every two weeks
Working builds are demoed live each cycle with CI running on every merge, so progress is visible in software, not slideware.
100% source-code ownership
All smart contract source, configurations, designs, and documentation transfer to you on delivery with no licensing strings or vendor lock-in.
60 days of post-launch support
Engineering time is on standby for two months after go-live to triage defects, tune performance, and stabilise the release at no extra cost.
12 months of free updates
Compatibility updates, security patches, and platform upgrades ship free for a full year after handover.
What you can build with smart contracts
Contract systems our team delivers, reviewed before mainnet, always.
Token launch suite
Token contracts with vesting, distribution, and governance, ready for a public launch with audit documentation.
Escrow and settlement logic
Trust-minimised escrow for marketplace, freelance, or trade settlement, with clear dispute paths.
Marketplace contracts
Listing, bidding, and royalty logic for digital asset marketplaces, gas-optimised for real usage.
Vesting and treasury contracts
Team, investor, and treasury vesting with credible timelocked administration.
Membership and access contracts
Token-based access and membership logic integrated with your application's permissions.
How a smart contract Project Runs
Six stages, each with a sign-off gate before the next begins.
- 01
Discovery
We map your contract goals, users, and constraints in a structured workshop, ending in a fixed written quote and an architecture risk list.
✓ step 01 complete - 02
Solution design
The smart contract architecture, integrations, and delivery plan are designed and reviewed before build work starts, so scaling later is not a rewrite.
✓ step 02 complete - 03
Foundation sprint
Repositories, CI, environments, and a walking skeleton are set up first. Something real runs on a staging URL before feature sprints begin.
✓ step 03 complete - 04
Sprint delivery
Two-week sprints with live demos every cycle. smart contract work is reviewed, tested, and merged continuously, so scope surprises surface early.
✓ step 04 complete - 05
Hardening and launch
Performance, security, and accessibility checks run against agreed budgets, followed by a staged contract launch with monitoring from hour one.
✓ step 05 complete - 06
Support and handover
60 days of included support, 12 months of free updates, and documentation that lets your internal team own the system with confidence.
✓ step 06 complete
The stack behind our contract work
Default choices, stated with reasons.
Languages and chains
Solidity on Ethereum and EVM chains, Rust on Solana, with framework tooling for testing and deployment as code.
Libraries
Battle-tested contract libraries as the foundation, with custom code kept minimal, because novelty is where exploits live.
Testing
Unit and fork-based integration tests against real chain state, with invariant testing on the paths that hold value.
Review tooling
Static analysis alongside systematic manual review, with findings tracked and remediation verified before deployment.
How intelligence flows through the tooling
What each layer reads, and what it changes.
Contract monitor
Watches contract events and state for anomalies.
Reads
Chain events, contract state
Changes
Alert queues and incident tickets
Audit assistant
Pre-screens code changes against known exploit patterns.
Reads
Diff sets, vulnerability databases
Changes
Review checklists and flags
Cost analyser
Projects gas costs across usage scenarios.
Reads
Contract bytecode, usage patterns
Changes
Optimisation recommendations
What's included, standard
The baseline on every smart contract engagement. Not an upsell tier, just the floor.
Fixed written quote
The price agreed at discovery is the price you pay, with change handled through explicit scope changes rather than silent drift.
Solution architecture document
System design, data flows, and technology decisions written down so your team can audit and own the result.
Dedicated project manager
One accountable point of contact with real authority over the delivery, not a message relay between time zones.
QA on every build
Automated and manual testing on each smart contract release candidate, with defects triaged before anything reaches production.
Security review
A checklist-based security pass covering authentication, data handling, and dependency vulnerabilities before launch.
CI/CD and environments
Pipelines, staging, and preview environments configured from week one, so releases are routine rather than dramatic.
Analytics and monitoring
Instrumentation wired before launch so you can see real user behaviour and system health from day one.
Documentation and handover
Code comments, runbooks, and architecture notes written for your next developer rather than for our convenience.
Security review included
Every contract ships with a systematic security review and verified remediation before mainnet deployment.
Audited contract development vs fast deployment
What the extra weeks buy, stated in incident terms.
| Criteria | Consideration | Reviewed Moxace Build | Deploy-First Development |
|---|---|---|---|
| Pre-mainnet review | Systematic, remediation verified | Optional, often skipped | |
| Upgrade strategy | Designed before deployment | Discovered when needed | |
| Admin controls | Multisig with timelocks | An owner key, hopefully safe | |
| Incident posture | Monitoring and runbooks ready | Improvise under pressure | |
| Cost of a bug | Caught in review | Caught in a post-mortem |

Why teams pick us for smart contracts
The differences live in engineering habits, not pitch decks.
Minimal by design
Contracts are written with the smallest attack surface that does the job, because every extra feature is extra exploit surface.
Review before mainnet, always
Systematic security review with verified remediation is included in every engagement, not sold separately or skipped under deadline pressure.
Upgradability designed in
Proxy, timelock, and multisig patterns are designed before deployment, so your governance story is credible from day one.
Operable, not just deployed
Deterministic deployments, monitoring, and runbooks ship with the contracts, so your team can run what it owns.
Track record since 2010
9,000+ projects and 3,900+ apps across 25+ countries, held to the same bar as everything else we ship.
