Rayls is redefining world finance by serving to banks securely tokenize property, combine privacy-preserving know-how, and rework 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 daily, 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 non-public and public chains, and why he believes tokenization and privacy-preserving know-how 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 biggest funding financial institution in Latin America. Throughout my profession there, I used to be an MD Accomplice chargeable for world operations and know-how, managing round 2,000 staff throughout Brazil, Chile, Colombia, Peru, Mexico, america, Canada, and the UK. At one level, I used to be additionally the CTO for your complete financial institution.
Being so near know-how, I acquired to know crypto in 2014 after I purchased my first bitcoins. From there, I began learning 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 ultimately migrate to blockchain rails.
We noticed that monetary establishments lacked the type of infrastructure they may 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 prime; it’s our first precept. Our mission is to deliver 100 trillion {dollars} in property on-chain by serving to banks undertake blockchain, tokenize property, and migrate legacy programs to blockchain infrastructure.
Rayls combines a public Ethereum-compatible chain with non-public networks for establishments. How does this unified method stability privateness, compliance, and interoperability?
It’s tough for a financial institution to maneuver immediately from off-chain programs to public blockchains. A lot of their merchandise, corresponding to certificates of deposit, are offered to their very own shoppers. They don’t essentially must concern these on a public chain, however they nonetheless need to tokenize and modernize.
Our mannequin permits a financial institution to begin by implementing its personal non-public community, the place it may well tokenize property, check flows, and concern tokenized deposits. This offers them consolation and management. Nevertheless, staying solely on a non-public community doesn’t mixture liquidity. That’s the reason our non-public networks are seamlessly built-in with the general public chain.
As an illustration, a financial institution can transfer tokenized property from its non-public community to the general public chain for liquidity or different use circumstances, corresponding to enabling shoppers to commerce, borrow, or lend in opposition to these property. We’re already working with a financial institution that plans to deploy a lending pool on a public chain the place others can deposit property to help lending actions.
This hybrid setup presents flexibility: non-public networks for top scalability, velocity, and safety, and interoperability with public chains for liquidity. One in all our real-world circumstances includes a financial institution with 65 million prospects issuing 1.2 to 1.3 million certificates of deposit each day. Doing that on a public chain could be far too gradual and costly, however with our setup, they will concern on the non-public community and switch solely chosen property to the general public chain when liquidity is required.
What particular challenges in conventional finance does Rayls purpose 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 1,000,000 tokens per day. Our non-public community reaches as much as 10,000 transactions per second, permitting a financial institution to tokenize a million property in about 5 minutes.
The second problem is privateness. We developed Rayls Enigma, a privacy-preserving protocol utilizing zero-knowledge proofs. Banks don’t need 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 know-how to lending, AMMs, and even auctions, all with privateness. These instruments permit banks to soundly signify, alternate, and retailer tokenized worth throughout completely different asset courses.
How do you see the way forward for blockchain adoption throughout the conventional finance system? Will tokenization reshape monetary markets?
Tokenization introduces a 24/7 monetary market, identical to crypto. It allows steady commerce, switch, and liquidity.
Second, stablecoins enhance cost infrastructure, making settlements on the spot and world. You possibly can transfer thousands and thousands in seconds wherever on the planet.
Third, tokenization allows liquidity aggregation. Think about a world the place all property, together with shares, bonds, actual property, and receivables, are tokenized. These property will be transferred, used as collateral, or exchanged immediately, unlocking huge liquidity that’s presently trapped in silos.
An awesome instance is from the DTCC, the biggest central counterparty in america. They not too long ago tokenized property so shoppers may commerce them within the U.S. after which use the identical property as collateral in Japan in a single day. That may be a enormous leap in market effectivity. We’re nonetheless within the early levels, however the transformation has already begun.
Do you assume banks are able to embrace DeFi-like infrastructure?
I feel it’s a journey. A couple of years in the past, crypto was virtually taboo in banks. Some even closed accounts of crypto firms. Nevertheless, as rules grew to become clearer, particularly in america, banks started realizing the potential of blockchain.
It isn’t a simple transition; it requires new know-how, expertise, and custody fashions. So banks are beginning small: tokenizing property in closed environments for their very own shoppers, then steadily increasing to extra open programs. 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 property. We’re at the beginning of a significant technological shift in finance.
Trying on the blockchain and finance trade as a complete, what traits or improvements do you discover most fun, and the way is Rayls positioned to reap the benefits of them?
Tokenization is certainly necessary, however the actual transformation will come when banks and monetary establishments begin providing on-chain companies.
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 could 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. By way of on-chain FX utilizing stablecoins, that transaction may occur immediately and transparently.
Moreover, that very same exporter may need to use their receivable, corresponding to a 30-million-dollar soybean cargo, to get financing. That commerce finance receivable could possibly be tokenized and positioned in a lending pool, the place traders 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 neighborhood and traders ought to look ahead to this yr and subsequent?
Sure, we’re presently launching our public chain testnet, and we’re thrilled with the outcomes up to now. We plan to go stay round December to make sure the chain is powerful and meets consumer necessities.
On the non-public community facet, we’re going stay with a buying and selling firm on a significant venture: the tokenization of commerce finance receivables. That may be a important milestone.
We’re additionally partnering to deliver 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 robust place to ship actual on-chain worth and broaden our neighborhood’s involvement in these transformative tasks.
