When Rayls opened its public mainnet on April 30, 2026, it did so with a roster that most blockchain projects spend years assembling. The Layer 1 chain, built by Parfin (core developer of Ralys), went live recently, and was preceded by Tether made a strategic investment in Parfin, the core developer of Rayls. That backing sits alongside Rayls’ inclusion in Mastercard’s Crypto Partner Program, a J.P. Morgan Kinexys deployment and a $1 billion partnership agreement with AmFi – all secured within the 18 months preceding launch.
The institutional momentum behind the chain reflects a broader shift in how large financial organizations are approaching blockchain infrastructure. Rayls offers verifiable sub-second finality and low gas fees on its public chain, alongside full EVM compatibility – a combination that lowers the integration cost for institutions already running Solidity-based systems. The technical baseline appears to have been a decisive factor for each of the major partners.
Tether and Mastercard inclusion signal infrastructure-level commitment
Tether’s strategic investment in Parfin closed in November 2025. This signals the world’s largest stablecoin issuer backing the company building Rayls at the infrastructure level, rather than simply deploying a token on top of it. In March 2026, Mastercard added Rayls to its Crypto Partner Program alongside Polygon, Solana, Ripple and Stellar – a shortlist that places the chain in the company of some of the most liquid and developer-active networks in the market.
AmFi’s $1 billion commitment anchors near-term volume
The AmFi partnership, announced in December 2025, is the deal with the largest direct volume implication. The agreement targets $1 billion in assets under management on the Rayls network by the end of 2027, with $100 million committed by July 2026 and $500 million by January 2027. The milestones represent contracted deployment rather than indicative targets, which gives the figures a different weight when assessing the chain’s near-term transaction volume.
J.P. Morgan’s Kinexys division – the bank’s blockchain and digital-assets infrastructure arm – has deployed on the network and independently assessed its privacy architecture. The Kinexys relationship also brings credibility to the chain’s regulatory positioning: Rayls is designed to operate within MiCA, CVM, BACEN and US financial-market frameworks, and J.P. Morgan’s involvement implies a level of compliance due diligence that most new chains do not receive at launch.
A 200 million-strong distribution network and live FX volume
XP Inc., Brazil’s largest independent investment bank, and Nuclea are issuing stablecoins on Rayls. AmFi brings tokenized real-world asset deployment, while Nimofast adds a pipeline of tangible real-economy assets and cash flows. Animoca Brands rounds out the roster on the digital-assets side. Across the full partner network, the combined end-client reach exceeds 200 million users.
Parfin’s own FX desk is scheduled to migrate approximately $400 million in monthly foreign exchange flows to the Rayls network from Q3 2026. That migration represents production transaction volume rather than a pilot, and the figure gives a concrete floor estimate for the chain’s early throughput under real commercial conditions.
Beyond the corporate partner base, Rayls has engaged with the Central Bank of Brazil, the Bank for International Settlements and the European Commission on digital-asset and stablecoin policy frameworks.
The public mainnet also brings Rayls’ RLS tokenomics live. The burn mechanism is designed to connect network activity with the token’s economic model, giving the chain a clearer link between institutional demand, transaction volume and its native token layer.
With the mainnet live, the focus shifts to delivery against the contracted milestones – $100 million with AmFi by July, the $400 million FX migration from Q3, continued stablecoin issuance from XP and Nuclea, and the expansion of asset activity through Rayls Private Networks. The sub-second finality and low gas fees that attracted the partner roster now face their first test at production scale.
