This article introduces how Solayer's VISA Emerald Card not only enables on-chain payments and daily spending but also allows participation in new IDO projects for airdrop activities.
Why open a VISA Emerald Card?
1. The Emerald Card is a crypto debit card launched by Solayer based on InfiniSVM, designed to seamlessly connect on-chain assets (such as USDC) with real-world consumption scenarios. The following are its key features and connection mechanisms:
2.a. A bridge between on-chain payments and real-world consumption
Direct use of on-chain assets: The Emerald Card allows users to spend on-chain USDC directly without needing to preload through centralized exchanges or fiat. Users can pay with USDC at merchants in over 200 countries and regions (like Starbucks) or withdraw cash from ATMs, with all transactions processed on-chain.
3. Visa-like settlement speed: Leveraging the high throughput of InfiniSVM (internal tests reaching 340,000 TPS) and low latency (1 millisecond confirmation), the Emerald Card achieves near Visa payment settlement speed, surpassing the cross-border efficiency of traditional payment networks.
4. Non-custodial design: The Emerald Card adopts a fully non-custodial framework, where user assets are managed by smart contracts, eliminating reliance on centralized entities, ensuring fund security and decentralization principles.
b. Mobile payments and global usability
Integration with Apple Pay and Google Pay: The Emerald Card supports Apple Pay and Google Pay, allowing users to complete 'tap payments' via their phones, enhancing convenience in consumption.
5. Global accessibility: Supports online and offline consumption worldwide and offers competitive foreign exchange rates, suitable for cross-border payment scenarios. Users can use the Emerald Card at any merchant supporting Visa, covering a wide range of consumption scenarios.
Here received an official notice from Solayer that holding an Emerald Card allows participation in the Sahara Labsai new pre-sale. The Emerald Card passes KYC directly, and being a local citizen, I also passed instantly. It's really a bit unbelievable.Additionally, regarding this KYC, the official said that you must log in with the Solana wallet you used in the last Solayer pre-sale to avoid KYC.
@Solayer is a next-generation high-performance blockchain project born for the Solana ecosystem, committed to addressing the core bottleneck of scalability and shared security in the current ecosystem. Its constructed InfiniSVM integrates two major paths: hardware acceleration and protocol reconstruction, aiming to achieve extreme performance of over 1 million TPS and promote the evolution of SVM toward infinite scalability.

1. InfiniSVM is a hardware-accelerated Solana Virtual Machine (SVM) blockchain developed by Solayer, aiming to achieve ultra-high throughput (>1M TPS), low latency, and infinite scalability through hardware optimization. The following is a detailed analysis of its core technical advantages:
Hardware acceleration and high throughput (>1M TPS)
2. Multi-executor cluster architecture: InfiniSVM employs a multi-executor architecture, significantly enhancing throughput by breaking down transaction processing into parallel-executed microservices. Traditional blockchains rely on single-machine architecture, which struggles under high load, while InfiniSVM overcomes this bottleneck through distributed computing and parallel processing.
Explaining the position of sUSD in the on-chain dollar ecosystem:
sUSD (Solayer USD) is a decentralized, physically-backed synthetic stablecoin based on Solana in the Solayer ecosystem, positioned as a key asset connecting on-chain finance with the real world. The following are its roles and advantages in the on-chain dollar ecosystem:
a. Innovation of decentralized stablecoins
Physical asset backing: sUSD is backed by low-risk assets such as U.S. Treasury Bills (T-Bills) and earns interest through the interest-generating feature of Solana's Token 2022 program, providing holders with an annual yield of 4-5%. This design brings the stable returns of traditional finance on-chain, attracting DeFi users and conservative investors.
Non-custodial and automated: sUSD operates through a decentralized request-for-quote (RFQ) protocol. Once users lock USDC, market makers automatically complete the asset tokenization, minting, and redemption processes through smart contracts, ensuring transparency and security, and reducing the risk of market manipulation.
b. Pillars of on-chain finance
Yield generation: sUSD holders can earn interest simply by holding the token, similar to the automatic appreciation of traditional bank accounts. This makes it a core tool for DeFi liquidity and asset management.
Infrastructure security: sUSD provides economic security support for decentralized infrastructure (such as cross-chain bridges and oracle networks) by participating in Solayer's Active Verification Service (AVS), enhancing the stability of the ecosystem.
High liquidity: Through the RFQ protocol, sUSD collaborates with multiple liquidity providers to optimize capital efficiency and yield while maintaining a 1:1 dollar peg, supporting instant minting and redemption.
c. Ecosystem integration
sUSD seamlessly integrates with other Solayer products (such as sSOL and Emerald Card), building a vertically integrated financial ecosystem. Users can participate in staking, payments, and cross-chain transactions through sUSD, enhancing ecosystem stickiness.
sUSD fills the gap between on-chain dollars and real-world assets, providing global users with permissionless access to dollar assets and promoting stablecoin innovation in the Solana ecosystem.
