Interlace

Interlace is a global card issuing and banking-as-a-service platform that removes the compliance and operational complexity standing between a business and its ability to issue branded payment cards. It sits beneath the application layer — the infrastructure that crypto exchanges, travel platforms, and fintech startups plug into when they want to offer customers a spending card without building the underlying rails themselves.

The Problem It Solves

Launching a card program has historically required direct relationships with card networks, navigating country-by-country licensing, and managing separate providers for issuance, settlement, and KYC. Interlace consolidates that surface into a single API that provides access to more than 30 card BINs and covers over 180 countries. Businesses can go from integration to live card program in roughly two weeks, compared to the months typically required to establish direct network relationships.

Core Mechanism

Interlace operates as a regulated financial intermediary sitting between businesses and the card networks. It holds licenses as a Money Services Business with FinCEN in the United States, is regulated as a Trust or Company Service Provider in Hong Kong, and holds an MSB license through FINTRAC in Canada. It also carries a European payments license in Lithuania. This multi-jurisdictional regulatory stack lets it issue across regions under a single API contract.

On the crypto side, the platform provides deposit addresses on supported blockchains, handles on-chain KYT (Know Your Transaction) for AML compliance, manages stablecoin conversion to spendable fiat balances, and feeds the resulting funds into the card issuance layer. The end result is a path from a wallet holding USDC on Solana to a physical or virtual card accepted wherever Visa and Mastercard are honored.

Key Products and Features

Cards as a Service (CaaS) is the core offering. It supports multi-BIN issuance of both virtual and physical cards, includes white-label API integration so partner brands can customize card presentation, and bundles real-time transaction monitoring and anti-fraud tooling. Interlace reached Visa Principal Member status — a designation that most fintech intermediaries never achieve — which deepens its access to Visa's network rails.

Wallet as a Service (WaaS) is the crypto-to-card bridge. It handles wallet management, deposit address generation, and blockchain transfers across 14 supported networks. The platform supports native USDC and USDT on Solana, alongside native versions of both stablecoins on Ethereum, Avalanche, Base, Arbitrum, Polygon, Optimism, TRON, and Ton. This multi-chain support lets Web3 businesses serve users regardless of which chain holds their funds.

Banking as a Service (BaaS) provides multi-currency business accounts denominated in USD, EUR, GBP, and HKD. These accounts support external transfers and payouts and can be combined with the card layer to create an integrated spend-and-settle product.

CryptoConnect is the on/off-ramp module. It converts between crypto and fiat and supports more than 40 currencies, making it the settlement bridge between a user's crypto holdings and the fiat-denominated card spend that merchants see.

Yield Treasury adds a 4% yield to idle treasury balances, giving business accounts a passive return on undeployed funds.

Infinity Cards are the direct-spend corporate card product aimed at businesses managing employee expenses in crypto-native environments.

Supported Assets and Networks

Solana is one of 14 blockchain networks supported in production. Native USDC and USDT on Solana are fully supported for wallet deposits and subsequent card spend. This positions Interlace as a practical spending layer for Solana-based applications and users who want to convert on-chain stablecoin balances into real-world purchasing power without a separate off-ramp step.

Security and Compliance

Interlace holds PCI-DSS Level 1 certification, the highest tier in the international card payment security standard. Card programs run on top of Visa Principal Membership. The KYT pipeline handles on-chain transaction screening as part of the deposit flow, and client KYC/KYB is built into the integration layer rather than outsourced to the partner.

Team and Background

Interlace was founded in 2019 in Singapore by CEO Michael Wu. The company has grown to more than 100 employees across five global offices. In December 2024, it closed a $10 million Series B1 round led by Bitrock Capital, with additional participation from senior alumni of Klarna and Robinhood. New hires at the time included a Head of Global Financial Partners, a Head of Global Operations, a Head of Marketing and Business Development, and a Creative Director. The company appeared at the PayFi Summit at Consensus Hong Kong in February 2025 alongside the Solana Foundation, Huma Finance, and DePHY, positioning itself within the emerging PayFi infrastructure conversation.

Scale

By mid-2025, Interlace reported more than 7 million cards issued, over 12,000 enterprise clients, and more than 60 million transactions processed annually. The platform spans 180-plus countries and 40-plus fiat and crypto currencies.

Solana Ecosystem Fit

Interlace occupies the spending layer of the Solana PayFi stack. Where Solana provides the fast, low-fee settlement rail for stablecoin balances, Interlace converts those balances into spendable card credit accepted globally. For Solana-based projects building crypto-to-card experiences — crypto exchanges, DeFi yield products, payroll tools, and neobanking applications — Interlace provides the regulated, multi-BIN card issuance infrastructure they cannot easily build themselves. Its native USDC and USDT support on Solana means the conversion path is direct, without bridging to another chain first.
