Blockchain & Crypto
On-chain products people can actually use.
Wallets, smart contracts, indexers and compliance tooling for Web3 teams who need security and a user experience normal people understand.
What Blockchain & Crypto teams tell usSolved
- “New users quit at “create a wallet””
- “Every contract change felt risky”
- “Compliance checks done by hand”
- “Reports needed data nobody could query”
Built for the standards you answer to
- KYC / AMLIdentity and risk
- Travel RuleFATF transfers
- MiCAEU crypto rules
- Audit-readySmart contracts
- SOC 2Security controls
- GDPREU data protection
Why it is hard
What makes Blockchain & Crypto software different
Six things we plan for on every blockchain & crypto project, before a single screen is designed.
Code you cannot undo
Once a smart contract is live, a mistake can lock or lose funds for good. Testing, audits and safe upgrade paths are essential.
What we actually do
- Full test suite and fuzz testing before every deployment
- Timelock and multisig approval on every upgrade
- Audit preparation pack ready for your external auditor
Wallets scare normal users
Seed phrases, gas fees and network switching lose most new users before they ever transact.
What we actually do
- Email or social sign-in with an embedded wallet
- Gas sponsored for first actions
- Plain-language confirmations before every transaction
Compliance still applies
Exchanges and payment products still need KYC, sanctions screening and transaction monitoring.
What we actually do
- Wallet screening on every deposit and withdrawal
- Travel Rule data exchange built into transfers
- A case queue with a full decision history for the regulator
Smart contracts you cannot undo
Once deployed, one bug in a contract can lock or lose funds permanently.
What we actually do
- Full test coverage plus fuzzing before deploy
- Independent audit before mainnet
- Upgrade paths and pause switches where they make sense
Wallet steps that scare normal users
Seed phrases, gas fees and failed transactions drive newcomers away in the first minute.
What we actually do
- Embedded and social-login wallets for new users
- Gas sponsored for key actions
- Plain-language previews before every signature
Rules that keep shifting
Regulations like MiCA and the Travel Rule change what you must collect, check and report.
What we actually do
- KYC and sanctions screening built into the flow
- Travel Rule data handled through compliant providers
- Rules configurable per region, not hard-coded

Problems we solve
Real problems, and what we built
The kind of day-to-day problems blockchain & crypto teams bring to us, and how we typically solve them.
Sign-up asked users to install a wallet, save a seed phrase and buy gas before doing anything.
An embedded wallet with email or social login, sponsored gas for first actions, and an optional upgrade to self-custody later.
Users reach their first transaction in a couple of minutes, without learning what gas is.
Account abstraction (ERC-4337)MPC walletsPaymaster
The team was afraid to ship fixes because contracts could not be upgraded safely and test coverage was thin.
Upgradeable contracts with a full test suite, fuzz tests, a timelock and multi-signature approval for every change, ready for external audit.
The team ships changes with confidence, and the audit came back with far fewer findings.
SolidityFoundryOpenZeppelinMultisig
Deposits and withdrawals were reviewed manually against sanctions and risk lists.
Automatic wallet screening on every transaction, risk alerts and a case queue for the compliance team.
High-risk activity is flagged in real time, and every decision is recorded for the regulator.
Chain analytics APIsRisk rulesCase management
Finance and product teams needed on-chain activity, but raw blockchain data was slow and hard to read.
An indexer that turns contract events into clean database tables, with dashboards on top.
Reports that took days of scripting now refresh on their own.
