In short
Cowchain builds compliance and custody into Web3 products from day one — MiCA and travel-rule readiness, KYC/KYT/AML and transaction monitoring, sanctions screening, and regulated + MPC custody integration — so compliance is engineered in, not bolted on. Usually bundled into stablecoin, RWA and exchange builds.

Why now
MiCAEurope's MiCA regime made compliance a build requirement, not an afterthought.
Regulation is now a build requirement. With MiCA live across the EU, the travel rule in force and stablecoin/RWA frameworks tightening globally, KYC/KYT/AML, sanctions screening and regulated or MPC custody have to be engineered into the product — not bolted on before launch. Getting this right is what lets institutions touch your build at all.

Custody models compared
Control, security and regulatory fit differ across custody approaches. Here's the comparison.
| Model | Who holds keys | Best for | Key build considerations |
|---|---|---|---|
| MPC custody | Distributed key shares | Self-managed, no single point | Share management, policy engine |
| Regulated custodian | Qualified custodian | Institutional requirements | Integration, approval workflows |
| Multisig | Multiple signers | Treasuries, DAOs | Signer ops, recovery |
| Hybrid | MPC + custodian | Balanced control & compliance | Policy routing, segregation |
Custody and licensing stay with regulated partners — we engineer the integration and controls.
