Smart Contract Development
Rust contracts written against near-sdk with full test coverage, simulation testing, and gas profiling before anything touches mainnet.
What we build
Full-stack NEAR development, from contract to interface
We cover the entire NEAR build: Rust smart contracts, the frontends users touch, and the indexing and integration layer that makes an on-chain product usable.
dApp Frontends
React applications wired to NEAR through wallet selector integration, with the transaction flows, error states, and account handling that separate a demo from a product.Token and NFT Systems
Fungible tokens, NFT collections, and staking or vesting logic built on the NEP standards, so your assets work across the NEAR ecosystem's wallets and marketplaces.Cross-Chain and Aurora
EVM deployments on Aurora and bridge integrations for teams that need NEAR's speed and fees without abandoning their existing Solidity codebase.Indexers and APIs
Custom indexing pipelines and query APIs over NEAR data, because on-chain state alone is never enough to power a real application's views and analytics.Contract Audits and Reviews
Line-by-line review of existing NEAR contracts covering access control, storage management, cross-contract call safety, and the failure modes specific to NEAR's async runtime.
How we work
From protocol design to mainnet deployment
(4)- 1
Protocol and Token Design
We work through your on-chain logic, account model, and economics before writing contract code, documenting the design so every later decision has a reference point. - 2
Contract Development
Contracts are built in Rust with unit and simulation tests from day one, including the cross-contract call and storage edge cases where NEAR projects usually break. - 3
Testnet Hardening
Full deployment to NEAR testnet with the frontend attached, where we load test, profile gas and storage costs, and run through failure scenarios before any real value is at stake. - 4
Mainnet Launch and Support
Audited deployment to mainnet with monitoring, key management procedures, and an upgrade path, followed by ongoing support as the protocol and your product evolve.
Why Webisoft
Blockchain engineers, not tourists
Webisoft has been building blockchain systems for years, across ecosystems. That depth matters on NEAR, where the async runtime and storage model punish teams that treat it like Ethereum.
Deep Protocol Experience
Our team has shipped smart contract systems across multiple chains and understands NEAR's specifics: sharded async execution, storage staking, and the NEP standards.Security First
Every contract goes through internal review, exhaustive testing, and gas and storage analysis before deployment. On-chain mistakes are permanent, so our process assumes hostile conditions.Senior North American Team
You work directly with the engineers writing your contracts, in your time zone, with communication that holds up under the pace of a token launch.Full Product Capability
We are a software studio, not a contract shop. The same team delivers your backend, frontend, and infrastructure, so the whole product ships coherent instead of stitched together.
FAQ
Common questions about NEAR Protocol development
(4)- A focused smart contract with tests and deployment typically runs in the tens of thousands, while a full dApp with contracts, frontend, and indexing is a larger engagement. The main cost drivers are contract complexity, the number of cross-contract interactions, and how much off-chain infrastructure the product needs. Fixed pricing after a design session is more reliable than estimating from a feature list alone.
- NEAR offers fast finality, transaction fees that stay in fractions of a cent, and human-readable account names, which matters for consumer-facing products where users will not tolerate Ethereum mainnet costs. Projects whose users and liquidity live in the EVM world can deploy on Aurora, NEAR's EVM-compatible layer, and get both. NEAR is not the right fit for every case, and the decision should follow from where the target users and assets actually are.
- Production NEAR contracts are written in Rust using near-sdk. JavaScript contracts exist for prototyping, but Rust is the standard for anything holding value, with better tooling, performance, and audit support. Teams planning a production launch on NEAR should budget for Rust expertise from the start.
- A takeover or audit starts with a technical review of the contracts and codebase, covering security, storage management, and upgrade safety, and produces a written findings report. Storage staking and upgrade patterns are NEAR-specific areas where problems commonly surface. From there, the work can target specific fixes or move to full ongoing development, depending on what the review shows.
Where we add value
NEAR development capabilities that matter in production
NEAR's account model, low fees, and Rust contract environment reward teams who know the platform's specifics. This is where our engineers spend their time on a NEAR engagement.
Rust smart contracts
We write NEAR contracts in Rust using near-sdk-rs, with unit tests, integration tests against a sandbox via near-workspaces, and explicit handling of storage staking costs. Rust's ownership model catches whole classes of bugs at compile time, but NEAR-specific pitfalls like cross-contract callback failures still need deliberate design, and that is where experience pays.Cross-contract call design
NEAR's asynchronous runtime means calls between contracts resolve in later blocks, so state can change between a call and its callback. We design promise chains with rollback logic for every failure branch, because the classic NEAR exploit is a callback that assumes the optimistic path. Getting this right is the difference between a demo and a system that holds funds.Account model and onboarding UX
Named accounts, access keys with scoped permissions, and meta-transactions let NEAR apps feel like normal web products. We use function-call access keys and relayers so users can start without buying tokens or installing a wallet, which removes the single biggest drop-off point in consumer dApp funnels.Chain abstraction and Aurora
When your users or liquidity live elsewhere, we work with NEAR's chain signatures and intents for cross-chain flows, and with Aurora when you want EVM compatibility with NEAR's fee profile. Choosing between native NEAR, Aurora, and a multichain design is an architecture decision we help you make with the trade-offs written down.Token and NFT standards
Fungible tokens on NEP-141, NFTs on NEP-171, and storage management under NEP-145 have real behavioral differences from their Ethereum counterparts, especially around storage deposits and transfer callbacks. We implement to the standards, test against reference implementations, and make sure wallets and marketplaces index your assets correctly.Indexing and full-stack delivery
Production dApps need more than a contract: we build indexers on NEAR Lake or use QueryAPI-style pipelines to serve fast queries, wire frontends through wallet selector, and set up monitoring for contract activity. You get a complete product, from chain to browser, with the off-chain infrastructure treated as seriously as the contract.
Our approach
How we deliver a NEAR project
(4)- 1
Protocol fit and architecture
We start by validating that NEAR is the right chain for the product, looking at fee sensitivity, onboarding requirements, and where your users already are. The output is an architecture document covering contract boundaries, what lives on-chain versus off-chain, and the account and key structure, with alternatives and their trade-offs recorded. - 2
Contract development and testing
Contracts are built in Rust with a test pyramid: unit tests, simulation tests in near-workspaces covering cross-contract failure paths, and testnet deployments exercised by scripted scenarios. Storage costs and gas budgets are measured per method as we go, so economic surprises show up in development rather than in production. - 3
Audit, review, and hardening
Before mainnet, contracts go through internal review focused on callback safety, access control, and storage exhaustion, and we coordinate third-party audits for anything holding meaningful value. Findings are fixed and retested, and we prepare upgrade and key management procedures, including whether the contract should be made immutable by removing keys. - 4
Mainnet launch and operations
Launch includes deployment runbooks, monitoring on contract calls and balances, an incident response plan, and indexer infrastructure running in your accounts. After launch we can stay on for iteration or hand over fully, with documentation your own engineers can operate from.
FAQ
Questions buyers ask about NEAR development
(6)- NEAR is strong when transaction cost and onboarding friction are the product's main constraints: consumer apps, high-frequency interactions, and products whose users do not already have wallets. Its named accounts and key model support email-style onboarding that is hard to replicate elsewhere. Ethereum and its L2s still win when you need deep DeFi liquidity or EVM ecosystem tooling, and Aurora offers a middle path. We help you make that call based on your users and economics, not chain loyalty.
- The dominant drivers are contract complexity, the amount of cross-contract interaction, and how much off-chain infrastructure the product needs, indexers and relayers in particular. A single self-contained contract with a simple frontend is a much smaller project than a protocol with multiple interacting contracts, token economics, and a custom indexer. Audit cost scales with contract size and value at risk. After the architecture phase we can quote fixed scopes with confidence.
- NEAR's asynchronous cross-contract calls are the platform's most common source of vulnerabilities, so our review process is built around callback failure paths, one-yocto access checks, and storage attack surfaces. Anything holding meaningful value gets a third-party audit, and we treat audit findings as blocking. We also design the key and upgrade policy explicitly, because a perfectly audited contract behind a single unprotected full-access key is still insecure.
- Yes, and this is one of NEAR's genuine advantages. Function-call access keys let an app sign scoped transactions on a user's behalf, and meta-transactions with a relayer let your product sponsor gas so users never touch tokens. We build these onboarding flows regularly, including progressive setups where users start with an embedded key and can export to full self-custody later. The cost is that you operate relayer infrastructure and absorb gas, which we model with you up front.
- NEAR contracts are upgradeable by default: whoever holds a full-access key on the account can redeploy code and run state migrations. That is operationally convenient and a governance question at the same time, since your users are trusting whoever holds that key. Options range from multisig or DAO-controlled keys to burning keys entirely for immutability. We implement migration paths, versioned state, and the key policy that fits your trust model, and we document it publicly if your users need that assurance.
- The typical entry point is the architecture phase: one to three weeks producing the technical design, on-chain versus off-chain split, cost model, and delivery estimate. If you already have contracts, we can start instead with a code review of the existing system. Both are fixed-scope, both leave you with documents your team can act on independently, and both give you a grounded basis for deciding on the full build.
