Building a Web3 product and need engineers fast?
Gaper assembles vetted blockchain engineering teams in 24 hours. Solidity, Rust, Move. Starting at $35/hr, roughly one fifth of what Toptal charges for the same caliber talent.
A blockchain tech stack is the combination of smart contract language, development framework, node infrastructure, frontend libraries, and indexing tools used to build a decentralized application in 2026. The most common 2026 stack is Ethereum with Solidity for smart contracts, Foundry as the dev framework, a node provider like Alchemy or Infura, Viem or Wagmi for the frontend, and The Graph for indexing.
That is a mouthful, so let us break it into layers the way we do with traditional web stacks.
If your stack comparison skips the indexing layer, it is not a real stack comparison. The indexing layer is the reason most Web3 products either ship or stall.
Five big shifts happened between 2022 and 2026.
First, Foundry replaced Hardhat as the default EVM dev framework. Foundry is written in Rust, runs tests roughly 100x faster than Hardhat, and has a fuzzing and invariant testing story that Hardhat never matched. Most serious new projects start on Foundry in 2026. Hardhat is still fine, and many legacy projects are still on it, but Foundry is where the momentum is.
Second, Viem replaced ethers.js v5 as the default TypeScript client. Ethers.js v6 fixed most of the v5 problems, but Viem was a ground up rewrite with better type safety, smaller bundles, and a more ergonomic API. Most new React and Next.js projects pick Viem plus Wagmi in 2026.
Third, Layer 2s went from “interesting experiment” to “the actual default”. In 2022 almost everything was on Ethereum mainnet with $50 gas fees. In 2026 most new projects launch on Base, Arbitrum, or Optimism first, with mainnet reserved for high value DeFi protocols. The rollup gas cost is roughly one one hundredth of mainnet.
Fourth, Solana’s ecosystem matured. In 2022 Solana was mostly NFTs and memecoins. In 2026 it has serious DeFi, consumer payment apps, and a mature Rust toolchain via Anchor. Solana handles consumer scale that Ethereum L1 cannot.
Fifth, the Move language got a second life through Sui and Aptos. Move was originally built at Facebook for Diem. It survived Diem’s death and is now the most security focused smart contract language in production use. If you are building something where one bug means losing hundreds of millions of dollars, Move is worth the learning curve.
Most stack guides skip the decision framework and go straight into the tool comparisons. We are going to do the opposite because picking the wrong stack is the single most expensive mistake you can make in a Web3 project.
The first question is not “which is the best tool”. It is “what are you actually building”.
Once you know your product type, score each candidate stack on these 5 criteria.
Here are the 7 stacks that cover almost every realistic Web3 product in 2026.
This is the stack most new Ethereum projects pick in 2026. Solidity for the contracts, Foundry for building and testing, Alchemy or Infura for node access, Viem and Wagmi for the TypeScript frontend. RainbowKit or ConnectKit for the wallet connection UI. The Graph for indexing.
Where it shines: Everything. This is the default.
2026 developer rate range: $50 to $200 per hour for a senior Solidity engineer. Gaper rates start at $35 per hour.
Hardhat 3 is still widely used, particularly by teams that started their project before Foundry matured. Hardhat has better JavaScript tooling integration (it runs on Node and feels native to JavaScript developers) and a more mature plugin ecosystem. If your team is JavaScript first and has never written Rust, Hardhat 3 may be the more comfortable choice.
Solana’s Anchor framework took Rust smart contract development from “nearly impossible for mortals” in 2021 to “doable with a learning curve” in 2026. Anchor handles the low level Solana program boilerplate and gives you a higher level developer experience. Pair it with @solana/web3.js or the newer @solana/kit library and the Solana Wallet Adapter for React integration.
2026 developer rate range: $80 to $250 per hour. Solana engineers are the most expensive smart contract developers in 2026.
This is the “same Solidity, cheaper gas” stack. Your contracts are basically identical to what you would write for Ethereum mainnet. The difference is that they run on a rollup that batches transactions and posts them back to Ethereum, which gives you roughly one one hundredth the gas cost with the same security guarantees.
Where it shines: Cost sensitive use cases, consumer apps, high frequency trading bots, any product where gas fees would otherwise eat margins.
zkSync Era is a zero knowledge rollup that supports Solidity with minor modifications. The big draw is faster finality and cheaper proofs. The tradeoff is that the tooling is still less mature than Base or Arbitrum. Pick zkSync if your application needs instant finality (for example, payments that cannot wait) and you can tolerate slightly rougher tooling.
Sui and Aptos both use Move, the language originally built at Facebook for Diem. Move’s claim to fame is “resource semantics”, which means assets cannot be accidentally duplicated or destroyed at the language level. If you have ever seen a Solidity reentrancy bug drain a DeFi protocol, Move is designed to prevent an entire class of those bugs from being possible in the first place.
2026 developer rate range: $100 to $280 per hour. Move developers are the highest paid smart contract developers because supply is so thin.
Polygon’s PoS chain is still a widely used EVM sidechain with cheap gas. The ecosystem is mature and most large consumer brands that launched NFT projects in 2021 and 2022 did it on Polygon. In 2026 the ecosystem has shifted toward Base and Arbitrum for new projects, but Polygon is still a reasonable choice if you have existing Polygon infrastructure.
Need Solidity, Rust, or Move engineers who can start this week?
Gaper’s pool of 8,200+ vetted engineers includes specialists in every smart contract language. Teams assemble in 24 hours. Starting at $35/hr.
The smart contract language you pick is a bigger commitment than the frontend library. It determines your talent pool, your audit costs, your bug profile, and your chain choices. Here is the honest comparison.
Pros: Largest developer pool by far. Most audit firms. Most tooling. Most libraries (OpenZeppelin is the industry standard). Most chains support it (every EVM chain). Easiest to hire for. Fastest to ship.
Cons: Language level safety is weaker than Rust or Move. Reentrancy bugs, integer overflow bugs (pre 0.8), and delegatecall bugs are real and have drained billions of dollars from DeFi protocols. Solidity requires discipline and audit budget to ship safely.
Pros: Memory safety, strong type system, excellent tooling through Cargo. Anchor on Solana gives you a higher level developer experience. Rust is also a useful general purpose language skill.
Cons: Steeper learning curve than Solidity. Rust smart contract developers are rarer and more expensive. The Solana specific programming model (accounts, rent, program derived addresses) has its own learning curve on top of Rust itself.
Pros: Resource safety at the language level. Assets cannot be copied or dropped accidentally. Formal verification tools are more advanced than in Solidity. Move was designed specifically for high value digital assets.
Cons: Extremely scarce talent pool. Ecosystem is still early. Audit tooling is less mature than Solidity.
| Use Case | Recommended Language | Rationale |
|---|---|---|
| DeFi on Ethereum L1 | Solidity | Ecosystem, liquidity, audit coverage |
| DeFi on Layer 2 | Solidity | Same contracts, cheaper gas |
| High throughput consumer app | Rust (Solana) | Transaction costs, finality |
| High value custody or bridge | Move (Sui/Aptos) | Resource safety at language level |
| Gaming or metaverse | Rust (Solana) | Transaction volume and cost |
Here is the realistic cost to build a production Web3 product in 2026 for a 2 to 4 person team. These numbers come from Gaper’s internal data on blockchain engineering projects plus 2025 to 2026 market rates.
| Product Type | Eng Hours | Audit Cost | Total Budget |
|---|---|---|---|
| Basic dApp (swap, staking) | 400 to 600 | $15,000 to $40,000 | $50,000 to $130,000 |
| NFT marketplace | 600 to 1,000 | $30,000 to $80,000 | $90,000 to $250,000 |
| DeFi lending protocol | 1,200 to 2,000 | $80,000 to $200,000 | $200,000 to $500,000 |
| Cross chain bridge | 2,000 to 4,000 | $150,000 to $400,000 | $400,000 to $1,200,000 |
Audit costs are a much bigger share of blockchain budgets than traditional web budgets.
Skipping or underfunding an audit is how protocols get drained. Anyone quoting cheaper is cutting corners on security.
Gaper.io in one paragraph
Gaper.io is a platform that provides AI agents for business operations and access to 8,200+ top 1% vetted engineers. Founded in 2019 and backed by Harvard and Stanford alumni, Gaper offers four named AI agents (Kelly for healthcare scheduling, AccountsGPT for accounting, James for HR recruiting, Stefan for marketing operations) plus on demand engineering teams that assemble in 24 hours starting at $35 per hour.
The engineer pool covers all three major smart contract languages. Solidity is the largest group, followed by Rust (Solana), followed by a smaller but growing Move (Sui and Aptos) specialist pool. Every engineer in the pool has been vetted on coding skill, communication, and production experience.
Toptal, the best known vetted marketplace, charges $150 to $250 per hour for Solidity engineers and more for Rust and Move specialists. Gaper’s direct model cuts out most of that markup. Senior Solidity engineers start at $35 per hour. Senior Rust engineers start at $45 per hour. Senior Move engineers start at $60 per hour. The engineers are comparable. Both Toptal and Gaper vet to roughly the top 1 to 3 percent of applicants. The difference is the price.
Most blockchain projects stall because hiring takes months. A senior Solidity engineer in the US market in 2026 typically takes 4 to 6 months to hire through traditional channels. Gaper cuts that to 24 hours. You describe your project, your stack, and your timezone preferences, and you get a vetted shortlist the same day. There is a 2 week risk free trial, so if the engineer is not a fit you pay nothing and pick someone else.

The best all round blockchain tech stack in 2026 is Ethereum plus Solidity plus Foundry plus Viem plus Wagmi. Foundry replaced Hardhat as the fastest EVM dev framework in 2024. Viem replaced ethers.js as the default TypeScript client. For cheaper gas with the same code, deploy to Base or Arbitrum. For high throughput consumer apps, use Solana with Rust and Anchor. For maximum language level security, use Sui or Aptos with Move.
If you are picking one smart contract language to learn or hire for in 2026, pick Solidity. The Solidity developer pool is roughly 10x larger than the Rust smart contract pool, the audit and tooling ecosystem is mature, and Solidity works on every EVM chain (Ethereum, Base, Arbitrum, Optimism, Polygon, zkSync, BNB Chain, and dozens more). Pick Rust only if you are specifically building on Solana, NEAR, or Aptos.
A basic dApp (token swap, staking, simple governance) costs $50,000 to $130,000 to build in 2026, including $15,000 to $40,000 for a security audit. An NFT marketplace costs $90,000 to $250,000. A DeFi lending protocol costs $200,000 to $500,000. A cross chain bridge costs $400,000 to $1,200,000. Audit cost is a much larger share of blockchain budgets than web budgets because skipping audits is how protocols get drained.
Foundry is the 2026 default for new Solidity projects. It is written in Rust, runs tests roughly 100x faster than Hardhat, and has a superior fuzzing and invariant testing story. Hardhat 3 is still widely used, particularly by JavaScript first teams and teams with legacy Hardhat projects. If you are starting a new project in 2026, pick Foundry unless your team has a specific reason to stay in Node based tooling.
Most new projects in 2026 should launch on a Layer 2 (Base, Arbitrum, or Optimism) rather than Ethereum mainnet. The gas cost is roughly one one hundredth of mainnet, the security still inherits from Ethereum, and your Solidity contracts run unchanged. The only reasons to launch on mainnet in 2026 are institutional DeFi TVL requirements, high value custody, or specific protocol interactions that only live on mainnet.
The fastest way to hire a vetted blockchain engineer in 2026 is through a curated platform like Gaper, which assembles teams in 24 hours from a pool of 8,200+ top 1% engineers starting at $35 per hour. Traditional hiring takes 4 to 6 months for a senior Solidity engineer in the US market. Freelance marketplaces like Upwork are faster but the lack of vetting means you spend weeks filtering. A middle option is Toptal, which is also vetted but charges $150 to $250 per hour, roughly 3x to 5x the Gaper rate.
