We develop custom ERC-20 tokens with governance capabilities, gas-efficient permits, snapshot voting, and seamless DeFi composability.
The ERC-20 standard is the foundation of the fungible token ecosystem on Ethereum and all EVM-compatible chains. While the basic interface is straightforward, a production-quality ERC-20 token requires careful decisions about governance capabilities, supply management, access control, and DeFi compatibility. Arthiq develops ERC-20 tokens that are professionally engineered, thoroughly tested, and ready for production deployment.
We build on OpenZeppelin's battle-tested ERC-20 implementation, extending it with the specific features your token needs. Whether you are launching a governance token for a DAO, a utility token for a protocol, a reward token for a platform, or a wrapped asset for cross-chain compatibility, we deliver a token contract that meets the highest standards of security and gas efficiency.
Our ERC-20 development includes not just the token contract itself, but the surrounding infrastructure — vesting contracts, distribution mechanisms, staking integration, and DEX liquidity setup. We deliver a complete token launch package, not just a standalone contract.
Modern ERC-20 tokens often extend the base standard with additional capabilities. We implement ERC20Votes for governance-enabled tokens that track voting power through checkpoint history. We add ERC20Permit for gasless approvals using EIP-2612 signatures, eliminating the need for a separate approval transaction before token transfers.
For tokens that need historical balance queries — for airdrops, revenue distribution, or governance snapshots — we implement ERC20Snapshot or checkpoint-based balance tracking. These features allow querying any address's balance at any historical block, which is essential for fair distribution events.
We also build tokens with custom transfer logic when the economic model requires it — transfer taxes that fund protocol treasuries, reflection mechanisms that distribute fees to holders, and transfer restrictions for compliance or vesting enforcement. Each custom feature is carefully tested to ensure it does not break composability with DeFi protocols.
Token supply management is a critical design decision. We implement fixed supply tokens with all tokens minted at deployment, mintable tokens with controlled minting authority, and capped tokens with maximum supply limits and scheduled minting. Burn functionality allows supply reduction through voluntary or automatic burning mechanisms.
Access control for minting, pausing, and administrative functions uses role-based systems from OpenZeppelin. We configure role hierarchies with the principle of least privilege — minting authority is separate from admin authority, and emergency pause authority is separate from upgrade authority. Multi-signature wallets are configured as role holders for production deployments.
For tokens that need regulatory compliance features, we implement pause functionality that can halt all transfers, blacklist capabilities for sanctioned addresses, and forced transfer mechanisms for court-ordered asset recovery. These features are optional and only included when the use case demands them.
A token's value is amplified by its composability with the DeFi ecosystem. We ensure that every ERC-20 token we develop integrates smoothly with DEXs, lending protocols, and yield platforms. This means conforming to the ERC-20 specification precisely, implementing standard events, and avoiding non-standard behaviors that could cause integration issues.
We set up initial DEX liquidity on Uniswap V3, SushiSwap, or other decentralized exchanges with appropriate price ranges and liquidity depths. For tokens that need liquidity incentives, we deploy corresponding staking contracts and configure reward distributions that attract liquidity providers.
Integration testing verifies that the token works correctly with major DeFi protocols before launch. We test deposit and withdrawal flows in lending protocols, swap execution on DEXs, and yield farming interactions. This pre-launch verification prevents the integration issues that have troubled many token launches.
Our deployment process includes testnet validation, mainnet deployment with Etherscan verification, and initial configuration. We deploy to Ethereum, Polygon, Arbitrum, Base, and Optimism, with chain-specific optimization for each deployment target.
Post-deployment, we set up token distribution infrastructure — airdrop contracts using Merkle tree claims, vesting contracts with configurable schedules, and team token lockup contracts. We also configure the token on portfolio trackers, price aggregators, and block explorers so that holders can track their balances accurately.
Arthiq provides ongoing token support including contract upgrades (if the token uses a proxy pattern), new feature implementation, and integration support as the token ecosystem grows. Our Singapore-based team treats your token as critical infrastructure. Contact founders@arthiq.co to discuss your ERC-20 token development.
