How a Bank Can Launch On-Chain Products Without Rebuilding Its Core Infrastructure
How a bank can launch on-chain products in reais without rebuilding its core, by adding an institutional on-chain real like BRLV as a thin layer.
A bank does not have to replace its core banking system to offer on-chain products. It can add an institutional on-chain real as a thin layer on top of what it already runs, and connect to it through an API. Crown issues BRLV to serve as that layer.
The core stays; a settlement layer is added
The core banking system keeps holding accounts and settling on banking rails. The on-chain layer is where tokenized balances and products live, denominated in reais through an on-chain real. The two connect at defined points: deposits in by Pix, redemptions out to reais, and movement on-chain in between. The bank builds the product, not the issuance, custody, and attestation underneath it.
What the thin layer provides
BRLV holds a 1:1 peg to the real, is fully backed by Brazilian federal government bonds, and keeps the principal available 24 hours a day, 7 days a week. It is an ERC-20 token issued on the Base, Ethereum, and Tempo networks, and Crown acts as issuer and attestor, controlling mint and burn against the bond reserves. That issuer-attestor model is described in how a BRL stablecoin is issued and redeemed. Because the real is already on-chain, banks and fintechs use BRLV as the base to launch digital wallets, programmable cards, and on-chain products without complex bank integrations.
What the bank integrates, not builds
Custody, identity, and reporting come with the layer rather than being rebuilt. BRLV custody runs on Fireblocks institutional infrastructure with multi-party computation and segregated per-client wallets, detailed in how a BRL stablecoin issuer custodies client tokens. Crown performs the mandatory reporting to the Central Bank of Brazil for operations on the platform, and the API is documented at docs.crown-brlv.com.
Where balances are held
Once the layer is in place, reais balances can sit in the bank’s wallet management or in any wallet the client prefers, including external ones, as covered in where a Brazilian real stablecoin can be held. The bank launches the product on top; the on-chain real handles issuance, backing, and settlement underneath.
