Recently, the crypto assets field has welcomed an innovative product - the Emerald Card, which is reshaping people's understanding of crypto asset consumption. This payment card developed by Solayer cleverly combines everyday spending with crypto mining, providing users with a brand new passive income channel.

Users only need to bind their Solana wallet with the Emerald Card to automatically convert USDC to sUSD (Solayer's stablecoin) during Visa transactions and earn an annual yield of 4%. Even more impressively, users' spending behavior can trigger on-chain rewards. Cardholders have the opportunity to participate in the "Build Pool" activity, with airdrop rewards of up to 280 LAYER tokens per week.
The smooth user experience of the Emerald Card is attributed to Solayer's InfiniSVM technology. This technology achieves a transaction confirmation time of 0.01 seconds and a bandwidth of 100 Gbps, ensuring that users can instantly complete on-chain asset settlements when swiping their cards. In addition, through collaboration with Nubit, the Emerald Card has become the first crypto Visa card to access the Bitcoin Thunderbolt network, supporting instant Bitcoin exchanges via the Lightning Network, significantly reducing cross-border payment fees.
The Emerald Rewards program employs a dual incentive model to attract users. First, users can earn 0.5% of their spending amount in LAYER tokens as basic rewards, which will be credited instantly. Second, the top 10% of users in quarterly spending rankings will have the opportunity to participate in DAO governance voting, influencing the treasury allocation strategy of sUSD reserves, thus deeply engaging in ecological construction.
This innovative consumption mining model seems to have garnered a good market response. According to reports, in the first week of the event going live, the number of users exceeded 500,000, with a single-day highest airdrop reward value reaching 23,000 USD.
The emergence of the Emerald Card not only provides users with a new way to obtain crypto assets, but also demonstrates the possibility of integrating crypto payments with traditional financial systems. As these innovative products continue to emerge, the application scenarios for crypto assets are gradually expanding, which may drive the entire industry towards greater accessibility.
