What's the difference between ERC-3643 and ERC-1400?

ERC-3643 enforces compliance through a global on-chain identity registry checked on every transfer, which keeps gas costs and integration complexity relatively contained. ERC-1400 partitions a token supply into separate tranches with independent rules, which fits multi-class structured products better but adds real complexity across its four underlying sub-standards.

Which blockchain should an RWA platform launch on?

Ethereum L1 (plus its L2s) still carries the deepest institutional liquidity and DeFi composability, which matters most for funds designed to be used as collateral elsewhere. Solana offers materially lower fees and faster finality and now dominates tokenized equities and ETFs. The right choice depends on whether deep DeFi integration or low-cost, high-frequency settlement matters more for the specific offering — and increasingly, platforms plan for both from the start rather than picking one.

How does on-chain compliance actually work at the smart contract level?

The token contract queries an identity registry (or, on Solana, triggers a Transfer Hook) on every transfer attempt. If the receiving wallet doesn't hold a valid KYC/accreditation claim for the relevant jurisdiction, the transaction is rejected automatically at the protocol level — no manual review or off-chain intervention required.

What is Proof of Reserve, and why does an RWA platform need it?

Proof of Reserve is an oracle mechanism that continuously verifies the off-chain assets backing a token — a custodial bank balance, for example — and feeds that data on-chain. It's typically wired directly into the mint function, so new tokens can't be created beyond what's actually backed, and it can double as an automatic circuit breaker in lending protocols if reserves drop below a safe threshold.

Does an RWA tokenization platform need a separate legal entity (SPV)?

For anything beyond a proof-of-concept, yes. Without an SPV or trust structure holding the underlying asset and isolating it from the platform operator's own balance sheet, the token has no enforceable legal claim behind it if the issuer runs into financial trouble. The SPV is what delivers bankruptcy remoteness for investors.

How much does it cost to build an RWA tokenization platform?

Cost is driven mostly by how much of the architecture is custom versus pre-built: a turnkey platform on an established token standard costs a fraction of a fully bespoke build with custom smart contracts, multi-chain support, and non-standard legal structuring. For a detailed line-item breakdown by build type, see OmiSoft's real estate tokenization platform cost guide — the same cost drivers apply across other RWA asset classes.

How long does it take to build a compliant RWA tokenization platform?

A turnkey deployment on an established token standard with standard KYC/AML and whitelisting logic can go live in a matter of weeks. A fully custom build — new smart contract logic, bespoke legal structuring, multi-chain architecture — typically runs months, largely because regulatory review and SPV formation drive the timeline more than the development work itself.

Who owns the source code on a custom RWA platform build?

That should be explicit in the contract before development starts. Pure white-label licenses generally don't transfer source code ownership. Turnkey and custom engagements should — it's worth confirming directly with any vendor, since some retain rights to reusable components even on projects billed as "custom."

Can a tokenized RWA platform integrate with a secondary market?

Yes, but it has to be architected for it — typically through a connection to a regulated Alternative Trading System (such as tZERO or INX) or a peer-to-peer transfer mechanism that still runs through the compliance layer's whitelist checks. This is worth confirming with any development partner before committing to an architecture, since illiquidity is the core problem tokenization is meant to solve in the first place.
