Crypto & Web3
Smart contracts, exchanges and wallet integrations — built secure from day one.
We have shipped production systems on Ethereum, Polygon, Arbitrum, Solana and Bitcoin Layer-2s. Every contract we write is reviewed by at least two senior auditors before it sees mainnet, and every key we manage lives in a hardware security module.
What's included
- Smart-contract design, implementation and gas optimisation (Solidity, Rust)
- External audit coordination with top-tier firms
- Wallet integrations: MetaMask, WalletConnect, Phantom, Ledger, Trezor
- Custody architecture using MPC and HSM-backed key management
- On-chain analytics, indexer infrastructure and explorer dashboards
Stack we usually pick
Deliverables
- 01Audited smart contracts deployed to mainnet
- 02Front-end dApp with wallet connect and transaction UX
- 03Indexer and subgraph for fast data access
- 04Operational runbook for treasury and key rotation
How we work
How we work
Threat model
We map every actor, every asset and every failure mode before writing code.
Implementation
Test-driven Solidity with 100% branch coverage and slither / mythril checks.
External audit
We coordinate with a third-party auditor and remediate every finding.
Launch & monitor
Mainnet deploy, on-chain monitoring and incident-response playbook.
Frequently asked
Frequently asked
Do you handle the smart-contract audit?+
We coordinate it. We have working relationships with CertiK, Trail of Bits, OpenZeppelin and Halborn — we package the code, manage the back-and-forth and ship the fixes.
Can you help with token economics?+
Yes — we have a tokenomics partner who joins early-stage projects to stress-test the supply schedule and incentives before launch.
Which chains do you support?+
Primarily EVM (Ethereum, Polygon, Arbitrum, Base) and Solana. We have also shipped on Bitcoin Layer-2s like Stacks.
