Blockchain & Web3 Development
Audited smart contracts, dApps, and tokenized platforms across EVM and high-throughput chains.
Blockchain and Web3 work at Prixelo means writing the contracts that hold value and building the applications people use to interact with them. On the contract side, that's Solidity for EVM chains and Rust for high-throughput chains, built on OpenZeppelin's audited standards rather than custom primitives reinvented from scratch. Every contract ships with a Foundry test suite — unit tests, fuzzing, and invariant checks — before it goes near an external audit, because catching a reentrancy bug in review is free and catching it on mainnet is not.
On the application side, this covers the full path from wallet to chain: dApps wired to WalletConnect and viem, token and NFT flows built on thirdweb where it speeds delivery without hiding the underlying contract logic, and The Graph for indexing on-chain data so a frontend isn't polling an RPC node for every state change. The same team writing the contracts builds the DeFi mechanics — DEX, lending, staking, and yield logic — the NFT and token launch flows, DAO governance and treasury systems, and RWA tokenization, so assumptions baked into the contracts don't get lost in translation to the frontend.
This fits teams putting real value on-chain who can't afford to discover a flaw after launch: founders taking a token or NFT collection to mint, protocols building lending or staking mechanics, and DAOs standing up governance and treasury infrastructure. Engagements start around $10,000 for a mint or token launch and scale to $35,000+ for a full dApp or DeFi protocol, sized to how much contract surface and audit rigor the project actually needs.
Our process
Scope & Architecture
Define contract architecture, choose EVM or Rust-based chains, and map the attack surface for the specific DeFi, NFT, or DAO mechanics before writing code.
Contract Development
Build Solidity or Rust contracts on OpenZeppelin standards for the mechanics the project needs — DEX, staking, minting, governance, or RWA tokenization.
Testing & Audit Prep
Run Foundry unit tests, fuzzing, and invariant checks against every contract path, then harden findings before external audit sign-off.
Integration & Launch
Wire the dApp to wallets via viem and WalletConnect, index on-chain activity with The Graph, and deploy to mainnet or testnet.
