DAO tooling startup
- Challenge
- ERC-20 voting hooks lacked cap checks and timelock on admin pause.
- Simplileap solution
- OpenZeppelin patterns, Slither/Mythril, and audit documentation pack.
- Outcome
- External audit: zero critical findings post-fix.

Solidity Smart Contract Development in Bangalore
Custom Solidity smart contracts: ERC-20 tokens, NFTs, DeFi logic, and protocol contracts. We treat every contract as a public attack surface, because it is. Fuzz tested, internally audited, and mainnet-deployed with verification.

Custom Smart Contract Development
Bespoke on-chain logic for your protocol.
Token Development
ERC-20, ERC-777, governance, and utility tokens.
NFT Smart Contracts
ERC-721, ERC-1155, royalties, and mint mechanics.
Smart Contract Testing & Deployment
Hardhat/Foundry test suites and mainnet deployment.
Contract Optimisation & Maintenance
Gas optimisation, upgrades, and ongoing monitoring.
// Standards
Smart contract security standards
Security-first design
Checks-Effects-Interactions pattern, reentrancy guards, minimal privilege, and pull-over-push payment patterns are non-negotiable in every contract.
Third-party audit recommended
For contracts handling significant user value, we strongly recommend and facilitate third-party audits from firms like Trail of Bits, ConsenSys Diligence, or OpenZeppelin.
Fuzz testing coverage
Foundry invariant tests and Echidna property-based fuzzing catch edge cases that hand-written unit tests miss, particularly for mathematical operations and state transitions.
Upgradeable when needed
Transparent proxy or UUPS patterns for upgradeable contracts; immutable deployment for trust-minimised contracts where upgradeability is a liability.
Gas-optimised by default
Storage packing, event vs. storage trade-offs, batch operations, and unchecked arithmetic where safe, gas costs are a user experience consideration.
Full NatSpec docs
Every public and external function documented with NatSpec, readable developer documentation generated automatically from inline annotations.

// FAQ
Common questions about smart contract development
What is the minimum viable smart contract engagement?+
A single contract type (e.g. ERC-20 token with custom vesting schedule) is our minimum scope. We do not implement contracts without a full specification phase, undefined requirements produce insecure contracts.
Do you recommend third-party audits?+
Yes, strongly, for any contract handling user funds. We conduct internal reviews as part of our process, but they do not substitute for specialist third-party audit firms. We can introduce you to firms we trust.
Can you upgrade deployed contracts?+
If the contract was deployed with a proxy pattern (Transparent or UUPS), yes. Immutable contracts cannot be changed by design, which is sometimes the correct security posture. We design upgrade strategies intentionally upfront.
What chains do you deploy on?+
All EVM-compatible chains, Ethereum mainnet, Polygon, Base, Arbitrum, Optimism, and BNB Chain. For high-value deployments, we recommend Ethereum L1 or audited L2s.
What does gas optimisation involve?+
Storage layout review (packing variables to minimise slots), replacing storage reads with events where read is not needed on-chain, using immutable variables, batch functions, and unchecked arithmetic in proven-safe loops.
