Solayer launches on-chain debit card, expands DeFi payment offerings

Solayer has unveiled a new suite of financial tools centered around the Emerald Card, a digital-first debit card.

This product is designed to bridge decentralized finance infrastructure with real-world payments, according to a company post on X.

At the core of Solayer’s offering are synthetic assets sUSD and sSOL, along with a high-performance virtual machine, infiniSVM, which the company claims can process one million transactions per second.

These elements power a growing vertical of DeFi applications, now tied to a payment system that connects directly with Visa networks.

The Emerald Card allows users to deposit USDC and access a variety of services including currency conversion, on- and off-ramps, ATM withdrawals, and wallet integrations with Apple Pay and Google Pay. 

Deposited funds can optionally earn yield through sUSD, which is linked to a 4% synthetic T-bill rate.

V0 release stage

The card is currently in its V0 release, with basic features including transaction history, balance top-up, the ability to freeze and unfreeze cards, and access to Emerald Rewards. This program offers incentives tied to real-world spending, according to the company post.

Points from “Solayer Season 2” are being distributed to card users, with rewards ranging from airdrops to merchandise. Access to the card is currently managed via a $75 pre-order fee and a rolling waitlist system.

Genesis airdrop recipients and presale participants are eligible to activate or claim their cards at reduced or no additional cost. The company also noted plans to expand access via referral programs and collaborations with partner protocols.

Solayer is positioning its ecosystem as a full-stack financial platform, combining digital savings and checking account features with real-world payment functionality and integrated DeFi incentives.
