Colosseum Codex: Superteam USA, Mastercard Partner Program, Jito Acquires SolanaFloor

Here's what's featured in this week's issue:

• Superteam USA has officially launched
• Mastercard introduced a Crypto Partner Program including Solana
• SolanaFloor returns after shutdown thanks to Jito

🦸 Superteam USA

Solana Superteam USA has officially launched, led by Nicky Scannella, founder of decentralized validation project Layer33 and host of The Index Show podcast. 

Superteam USA operates as a community of founders and developers across the US. Day-to-day work includes connecting developers with founders, helping teams hire, organizing events, supporting fundraising, and assisting consumer apps with on-chain payments and user data.

Scannella cites consumer apps, trading infrastructure, and agentic payments as Solana's biggest near-term opportunities, noting the chain's speed and cost as natural rails for autonomous agent transactions. 

The chapter's near-term goal is to help ten teams that wouldn't otherwise have touched Solana integrate it meaningfully. Longer term, Scannella wants to help double the current count of seven Solana companies generating over $100M in annual revenue.

Superteam USA is headquartered/launching from Miami, and prioritizing Miami founders in applications right now

💳 Mastercard Crypto Partner Program

Mastercard introduced a Crypto Partner Program connecting more than 85 companies across crypto, payments, and fintech, including Solana

The initiative creates a forum for blockchain developers, financial institutions, and payment providers to build practical digital asset applications on top of existing card networks and global commerce infrastructure.

The program targets cross-border remittances, B2B transfers, settlement, and stablecoin payments. Participants work directly with Mastercard teams to design products that combine digital asset speed and programmability with compliant, scalable card infrastructure.

Solana already has concrete integrations in the pipeline. Kazakhstan's central bank launched a tenge-pegged stablecoin (KZTE) on Solana that Mastercard plans to enable for card payments within the country's regulatory sandbox. Mastercard also added support for $FIUSD, a Solana-based stablecoin launched by financial services firm Fiserv.

Crypto-linked card payments grew rapidly in 2025, with Visa currently processing roughly 90% of total volume according to analytics firm Artemis. Mastercard's program signals a direct push to compete in that expanding market.

📰 Jito Relaunches SolanaFloor

Jito Foundation acquired SolanaFloor, bringing the publication back online after it went dark following a hack at its former parent company, Step Finance.

SolanaFloor retains full editorial and creative independence under Jito's ownership. Jito Foundation President Brian Smith framed the acquisition as an investment in ecosystem public goods: 

When SolanaFloor went dark, the ecosystem lost something difficult to replace. This acquisition is about filling the gap with a platform that operates from a position of editorial independence.

Originally launched in 2021 as an NFT analytics platform, SolanaFloor was acquired by Step Finance in 2022 and pivoted to full ecosystem news coverage. The newsroom resumes all services immediately, with news, data analytics, investigative journalism, and video content.
