Thanks! Here's the latest news for Solana devs...
🌉 Colosseum Accelerator SF
Colosseum’s eight-week accelerator now includes a dedicated two-week, in-person event in San Francisco's Financial District, followed by six weeks of remote programming.
During those first two weeks in SF, founders receive:
- Dedicated office space in the heart of the ecosystem
- Direct access to 1:1 mentorship and go-to-market support
- A Demo Day attended by 150+ investors
- Entry into Solana’s deepest founder network
To qualify, teams must complete the ongoing Eternal challenge or win one of Colosseum’s biannual hackathons.
The full program combines hands-on IRL collaboration with weekly educational sessions, an exclusive founder community, and online follow-up to help crypto startups achieve product-market fit and accelerate their seed rounds.
🏆 Eternal Winners
Colosseum is also pleased to announce the first two teams selected from Eternal to join the next cohort of the Colosseum Accelerator:
- @slant_ai is an AI data scientist for Solana, building research-grade analytics tools to support developers, investors, and researchers.
- @Tempo_Trade is an automated trading bot platform engineered for Solana, offering ultra-fast execution and zero-slot transaction landing to optimize trading strategies.
The remaining spots in Colosseum’s upcoming accelerator cohort will be filled by top teams from the Breakout hackathon. Additional selections will be announced in the coming weeks.
Founders interested in Eternal and launching a focused four-week development sprint can learn more below.
Eternal is now active again! Founders can join today to begin their four-week development sprint and be considered for the next accelerator cohort.
🛠️ Metaplex CLI
Metaplex has launched a public beta of its new CLI for Solana designed to simplify token and NFT workflows by providing direct terminal commands for common tasks.
Core capabilities include creating and managing both fungible tokens and NFTs, uploading and updating metadata, and inspecting asset or collection details.
You can switch between wallets and RPC endpoints instantly, burn or update assets, and generate metadata files with a single command. Additional utilities cover SOL transfers, balance checks, airdrops for testing, and rent calculations.
Metaplex CLI allows developers to build NFT applications and manage on-chain assets directly from a terminal with a simplified, script-free workflow.
🪄 Dev.fun Devbase
Devbase is an onchain data engine that powers payments, token logic and storage in Dev.fun apps, enabling wallet integration and transaction logic without writing backend code.
Devbase functionality is activated by including “Use wallet” or “Use vault” instructions in your initial prompt when you start a new app and describe a transaction.
You can inspect your Devbase setup at any time via a live schema visualization in the chat interface. Whenever you add or change data fields or transaction instructions, Dev.fun will update this schema to show:
- The structure of your stored data
- The on-chain operations that will run
If you need a deeper explanation of how your app’s on-chain logic works, switch to Brainstorm Mode and enter “Explain my schema.”
The AI will then walk you through:
- The conditions that trigger each transaction
- Which accounts send or receive funds
- Any vault rules or escrow mechanics in place
This combination of live schema and on-demand explanation gives you full visibility into your app’s data model and transaction flows.
Example applications include a meme generator tokenized to your coin or a simple marketplace charging SOL for item purchases.
💵 Maple Finance syrupUSDC
Maple Finance has brought syrupUSDC, its yield-bearing stablecoin, to Solana.
This launch includes $30 million in on-chain liquidity and up to $500 000 in phased incentives to encourage lending and liquidity provision.
Chainlink’s Cross-Chain Interoperability Protocol (CCIP) enables this support by allowing syrupUSDC to move securely and seamlessly between Ethereum and Solana.
CCIP went live on Solana mainnet in May and uses Chainlink’s decentralized oracle network to handle cross-chain transfers with configurable rate limits and built-in risk management.
Several leading Solana DeFi applications have already integrated syrupUSDC:
- Kamino Finance has added it across its Lend, Multiply and Liquidity Vault products, making it the primary venue for accessing Maple’s yield on Solana
- Orca offers direct swaps into syrupUSDC and contributes to its TVL
For Solana developers, the launch of syrupUSDC on Solana offers access to a fully on-chain, institutional-grade stablecoin with a fixed yield of around 6.5% percent without the need to write or deploy custom programs for interest-bearing assets.
⛰️ mtndao v8
Now in its fourth year, mtndao will host its eighth edition from August 1–31, 2025, in downtown Salt Lake City. This invite-only summit brings together Solana founders, developers, marketers, and investors.
mtndao has a track record of spawning award-winning projects and hackathon champions.
To support this creative community, v8 will feature a newly upgraded, around-the-clock workspace complete with 90 Autonomous Labs desks, Secretlab chairs, and enterprise-grade Wi-Fi.
After a v7 turnout that exceeded capacity by over 50% and doubled the size of any previous mtndao event, mtndao will be implementing new policies to preserve the quality of the experience for all attendees.
