ERC-20, ERC-721, ERC-1155, and custom token standards — fully audited Solidity and Rust contracts on EVM and Solana.
Most smart contract bugs are discovered after deployment — when funds are at risk and reputational damage is done. Generic contract templates miss edge cases in custom tokenomics, and unaudited code creates legal and financial exposure for the founding team.
We build every contract from the ground up, following OpenZeppelin standards and the CEI pattern. Every contract ships with comprehensive Foundry test suites, Slither static analysis, and an internal security review. We coordinate third-party audits for contracts managing significant TVL.
Define token supply, emission, vesting schedules, access control roles, and upgrade path. Document every business rule the contract must enforce before writing a line of code.
Implement using OpenZeppelin base contracts, following CEI pattern throughout. Comprehensive NatSpec documentation and access control from day one.
Foundry unit tests covering all paths including edge cases. Slither static analysis. Gas optimisation pass. Internal security review by a second engineer.
Coordinate third-party audit for high-value contracts. Testnet deployment and UAT. Mainnet deployment with monitoring, incident response plan, and pause capability.

Delivery timeline
We build ERC-20 (fungible tokens), ERC-721 (NFTs), ERC-1155 (multi-token), ERC-4626 (tokenised vaults), ERC-3643 (compliant security tokens), and fully custom standards for unique use cases. On Solana we implement SPL tokens and custom program logic in Rust.
Every contract we deliver undergoes internal audit using Slither static analysis and Foundry fuzz testing before handover. For contracts managing $500K+ in TVL, we strongly recommend and coordinate third-party audits with established Web3 security firms. Audit cost is separate from development cost.
Yes. We implement UUPS and Transparent Proxy patterns with proper access controls and timelock governance. Upgrade proposals require multisig approval to maintain trust with users.
EVM chains (Ethereum mainnet, Arbitrum, Base, Optimism, Polygon, BNB Chain) as primary, with Solana for high-throughput requirements. We advise on chain selection based on your transaction volume, gas economics, and target user base.
Yes. We build full launchpad platforms — tiered allocation systems, automated vesting contracts, KYC/whitelist gating, and real-time dashboards. We have delivered IDO platforms that have hosted multiple token launches with combined seven-figure raises.
