Rayls is redefining world finance by serving to banks securely tokenize belongings, combine privacy-preserving expertise, and remodel conventional markets right into a 24/7 blockchain-powered monetary system.

A single financial institution working with Rayls points over 1.3 million tokenized certificates of deposit on daily basis, a formidable instance of how blockchain can already deal with actual monetary scale. On this interview, Marcos Viriato, CEO at Parfin and Builder at Rayls, discusses his journey from conventional banking to Web3, how Rayls bridges the hole between personal and public chains, and why he believes tokenization and privacy-preserving expertise will redefine the way forward for world finance.
Are you able to please introduce your self as knowledgeable and inform us about your journey into Web3?
I’ve been working in conventional finance for about 25 years, spending 13 of these at a financial institution referred to as BTG Pactual, the most important funding financial institution in Latin America. Throughout my profession there, I used to be an MD Accomplice liable for world operations and expertise, managing round 2,000 staff throughout Brazil, Chile, Colombia, Peru, Mexico, the US, Canada, and the UK. At one level, I used to be additionally the CTO for all the financial institution.
Being so near expertise, I received to know crypto in 2014 after I purchased my first bitcoins. From there, I began finding out blockchain and its protocols. I spotted that blockchain had the potential to resolve a significant drawback in monetary markets: liquidity fragmentation. After I left the financial institution in 2019, I took a sabbatical and mirrored on how monetary markets, as we all know them, would finally migrate to blockchain rails.
We noticed that monetary establishments lacked the type of infrastructure they might belief and comfortably use. That’s the reason we began constructing Rayls, a blockchain designed for banks and monetary establishments, targeted on compliance, on-chain KYC, suitability checks, and different options banks require. Safety is key; it’s our first precept. Our mission is to convey 100 trillion {dollars} in belongings on-chain by serving to banks undertake blockchain, tokenize belongings, and migrate legacy methods to blockchain infrastructure.
Rayls combines a public Ethereum-compatible chain with personal networks for establishments. How does this unified method stability privateness, compliance, and interoperability?
It’s troublesome for a financial institution to maneuver straight from off-chain methods to public blockchains. Lots of their merchandise, akin to certificates of deposit, are bought to their very own shoppers. They don’t essentially must subject these on a public chain, however they nonetheless wish to tokenize and modernize.
Our mannequin permits a financial institution to begin by implementing its personal personal community, the place it may tokenize belongings, take a look at flows, and subject tokenized deposits. This offers them consolation and management. Nevertheless, staying solely on a personal community doesn’t mixture liquidity. That’s the reason our personal networks are seamlessly built-in with the general public chain.
For example, a financial institution can transfer tokenized belongings from its personal community to the general public chain for liquidity or different use circumstances, akin to enabling shoppers to commerce, borrow, or lend in opposition to these belongings. We’re already working with a financial institution that plans to deploy a lending pool on a public chain the place others can deposit belongings to help lending actions.
This hybrid setup affords flexibility: personal networks for prime scalability, pace, and safety, and interoperability with public chains for liquidity. Certainly one of our real-world circumstances includes a financial institution with 65 million clients issuing 1.2 to 1.3 million certificates of deposit day by day. Doing that on a public chain can be far too sluggish and costly, however with our setup, they will subject on the personal community and switch solely chosen belongings to the general public chain when liquidity is required.
What particular challenges in conventional finance does Rayls intention to deal with? How does your platform allow banks to soundly undertake blockchain and DeFi options?
The primary problem is scalability. Conventional blockchains like Ethereum can course of round 300 to 400 transactions per second, which isn’t sufficient for banks issuing over one million tokens per day. Our personal community reaches as much as 10,000 transactions per second, permitting a financial institution to tokenize a million belongings in about 5 minutes.
The second problem is privateness. We developed Rayls Enigma, a privacy-preserving protocol utilizing zero-knowledge proofs. Banks don’t wish to expose consumer balances, transaction quantities, or holdings. Our protocol preserves this confidentiality whereas permitting them to make use of blockchain securely.
We’re additionally increasing this privacy-preserving expertise to lending, AMMs, and even auctions, all with privateness. These instruments permit banks to soundly characterize, alternate, and retailer tokenized worth throughout completely different asset courses.
How do you see the way forward for blockchain adoption inside the conventional finance system? Will tokenization reshape monetary markets?
Tokenization introduces a 24/7 monetary market, similar to crypto. It permits steady commerce, switch, and liquidity.
Second, stablecoins enhance cost infrastructure, making settlements immediate and world. You may transfer hundreds of thousands in seconds wherever on this planet.
Third, tokenization permits liquidity aggregation. Think about a world the place all belongings, together with shares, bonds, actual property, and receivables, are tokenized. These belongings might be transferred, used as collateral, or exchanged immediately, unlocking monumental liquidity that’s at present trapped in silos.
A terrific instance is from the DTCC, the most important central counterparty in the US. They not too long ago tokenized belongings so shoppers might commerce them within the U.S. after which use the identical belongings as collateral in Japan in a single day. That could be a enormous leap in market effectivity. We’re nonetheless within the early phases, however the transformation has already begun.
Do you assume banks are able to embrace DeFi-like infrastructure?
I feel it’s a journey. A number of years in the past, crypto was nearly taboo in banks. Some even closed accounts of crypto firms. Nevertheless, as rules turned clearer, particularly in the US, banks started realizing the potential of blockchain.
It isn’t a straightforward transition; it requires new expertise, expertise, and custody fashions. So banks are beginning small: tokenizing belongings in closed environments for their very own shoppers, then steadily increasing to extra open methods. Some establishments are already well-prepared, having spent years constructing digital asset divisions and tech stacks.
Now, with regulatory readability, we see extra banks eager to launch stablecoins, undertake crypto, and tokenize belongings. We’re in the beginning of a significant technological shift in finance.
Trying on the blockchain and finance business as a complete, what traits or improvements do you discover most fun, and the way is Rayls positioned to benefit from them?
Tokenization is unquestionably necessary, however the true transformation will come when banks and monetary establishments begin providing on-chain providers.
For instance, think about utilizing an AMM to carry out an on-chain FX transaction, changing a non-USD stablecoin right into a USD stablecoin immediately. The liquidity in these AMMs can be supplied by monetary establishments.
Image this: an exporter in Argentina sells soybeans to China. The Chinese language purchaser pays in yuan, whereas the Argentine vendor wants pesos. Via on-chain FX utilizing stablecoins, that transaction might occur immediately and transparently.
Moreover, that very same exporter would possibly wish to use their receivable, akin to a 30-million-dollar soybean cargo, to get financing. That commerce finance receivable might be tokenized and positioned in a lending pool, the place buyers present liquidity in alternate for yield. We’re already implementing this with a significant buying and selling firm producing 3 billion {dollars} in annual income.
That is the place Rayls brings actual worth by enabling environment friendly, tokenized, and privacy-preserving finance.
Are you able to share any upcoming product milestones, partnerships, or pilots that the group and buyers ought to look ahead to this 12 months and subsequent?
Sure, we’re at present launching our public chain testnet, and we’re thrilled with the outcomes to date. We plan to go dwell round December to make sure the chain is powerful and meets consumer necessities.
On the personal community aspect, we’re going dwell with a buying and selling firm on a significant challenge: the tokenization of commerce finance receivables. That could be a vital milestone.
We’re additionally partnering to convey our privacy-preserving AMM protocol to market. There are extra thrilling collaborations within the pipeline, some we can’t disclose but, however we’re in a powerful place to ship actual on-chain worth and increase our group’s involvement in these transformative tasks.
