// web3
On-chain code, written like financial software.
Smart contracts, dApps and DeFi protocols by engineers who understand that a deployed bug is a transferred bug. Security-first, audit-ready, mainnet-tested.
// ledger · services
Six blocks. One chain of custody, from spec to mainnet.
Smart contract development
EVM, Solana & Cosmos. Production-grade Solidity, Rust and CosmWasm.
Architecture, implementation, unit + fork tests, gas optimization and deployment. We write contracts the same way we write financial software — because that is what they are.
dApp development
React/Next.js front-ends that handle wallets, RPC failures and reorgs gracefully.
Wagmi/Viem on EVM, @solana/web3.js on Solana. Optimistic UI, offline tolerance, indexer fallbacks, and clean UX even when the chain misbehaves.
DeFi protocols
AMMs, lending, staking, yield routers, perpetuals — with audited math.
We model every protocol in Python or Foundry before a line of Solidity is written. Invariants, fuzzing, formal-verification-friendly architectures.
NFT platforms
Mint engines, marketplaces, royalty enforcement and metadata pipelines.
ERC-721/1155, ERC-4907, on-chain & off-chain metadata, lazy-mint, allow-list logic, anti-bot strategies and resilient IPFS/Arweave pinning.
Security audits
Pre-deployment audits, fix-and-retest engagements, ongoing monitoring.
Manual line-by-line review + Foundry fuzz + Slither/Mythril static analysis. We hand over a public-quality report your community will actually read.
Chain integration
Bridges, oracle integrations, off-chain workers, indexers and analytics.
TheGraph, Subsquid, custom indexers. Chainlink, Pyth, RedStone. Cross-chain via LayerZero / CCIP — with replay protection done properly.
// security_first
A deployed contract is a permanent contract. We act like it.
Every contract we ship goes through threat modelling, invariant testing, fuzzing, slither, manual review, and at minimum one external audit before it sees mainnet. We don't ship to mainnet at 2am. We don't disable tests "just for now". We don't merge on red.
