Aura Onboarding Wallet

DeFi, Consumer Apps, Infrastructure

Solving for the onboarding dilemma. Most crypto natives avoid the onboarding effort because it takes at least 2hours to run interested people though it all - from downloading a wallet, what a seed is, what Solana is, that it’s not bitcoin, what X is, who Toly is why Raj will kill you etc… So just short of airdropping a QR+seed to a pre-funded wallet into NYC on a busy Friday, we came up with this “normie airdrop" tool. A simple 2-step download from app stores cuts the friction to bare minimum. They land to a wallet pre-funded with Aura and Solana. Here they will have all the basic resources of how to navigate crypto with essential information. The stuff we all wish we knew before getting rugged on drainers, farms and Hayden coins. Now that they are in - they can explore the rest of what Solana has to offer while always knowing they can refer back to the Aura app for guidance.

Veintree is building a biocryptography MVP enabling cryptocurrency operations without seed phrases, through an ethical biometric scanner, embedded authentication tokens, and post-quantum secure communications.

Autonomous Vehicle Micropayments

DeFi, Consumer Apps, Infrastructure

This project outlines a **Solana+IoT+Orchestrator** designed to revolutionise autonomous vehicle delivery networks by implementing **decentralised micropayment solutions**. This system leverages the **Solana blockchain** to provide lightning-fast, secure, and trustless transactions for delivery services, primarily focusing on automating payments within a multi-agent **IoT environment**. Key features include **Escrow Payments** to secure funds until delivery completion, **Multi-Agent Coordination** for fleet management, and **Automatic Settlement** via smart contracts upon successful delivery. The architecture details how participants, such as the **Customer**, **Vehicle Operator**, and **Authority**, interact with on-chain components like **Program Derived Addresses** (PDAs) and specific **Smart Contract Functions** to manage configuration, vehicle registration, order creation, and payment distribution.

Autonom - Unleashing RWAs in Solana

DeFi, RWAs, Infrastructure

Apart from Ostium (one standalone perp DEX), RWAs and particularly equities haven’t really hit perps or at least not in Solana. Confidence in these assets is weak and thus leverage is low compared to crypto. Equities go through all kinds of corporate actions (such as splits, dividends, or M&A) which impact share price and this is something which incumbent oracles don’t account for. They offer real-time prices but lack the account-based context that can be crucial to a trade. As a result, onchain perpetual future derivatives (perps) or lend/borrow applications face a choice: lack confidence, accept manual pricing risk or exclude these assets entirely. Autonom is a specialized oracle for RWAs, factoring in for corporate action adjustments, enabling dynamic pricing on-chain. For perp DEXs, Autonom also has a funding service and a risk a module with recommendations to deleverage or to return to baseline leverage around risk windows.

Avalon

DeFi, RWAs

We are transforming the Cape Town property market, making it accessible, tradable and yield generating for everyone. Investors can now earn real returns on premier real estate, trade instantly and do it all within a fully compliant framework.

Avlon

DeFi, RWAs, Infrastructure

Our project builds a Confidential Cross-Chain P2P Exchange powered by Arcium’s MPC engine, enabling privacy-preserving identity verification and atomic trading across Solana and EVM chains. It solves the core problem of on-chain exposure -> where public ledgers reveal user identities, trade sizes, and wallet links -> by using Multi-Party Computation to verify legitimacy without revealing data. Each trade executes securely through encrypted MPC tasks, ensuring confidentiality while maintaining transparency for auditability. This approach adds value to the Web3 and Solana ecosystem by introducing a privacy-native interoperability layer that supports compliant, cross-chain trading. It enhances user security, expands liquidity by attracting privacy-conscious participants, and lays the foundation for next-gen DeFi primitives like confidential lending and dark liquidity pools -> building a more secure, compliant, and user-centric financial internet.

Avoid.net

DeFi, Consumer Apps, Undefined

AVOID.NET is a blockchain-incentivized consumer protection platform that combines Wikipedia's collaborative model with cryptocurrency economics.

Helpful content results in refunds and rewards when approved, while scammers and spammers lose their deposit.

Axis

DeFi, Consumer Apps, Infrastructure

Axis is crypto’s S&P 500. Your smartest move? Do nothing. Own the top five cryptos with one token Key points - Institutional-grade security: Private execution via JitoBAM, shielded from harmful MEV. - Drawdown-resilient portfolio: Inverse-volatility weighting with quarterly rebalancing. - Low fee: A simple 0.95% per year.

Axon

DeFi, Consumer Apps, Undefined

Small Bitcoin miners are economically excluded from mining. High gas fees force traditional pools to set minimum payouts of $100+ (0.001 BTC), trapping the earnings of small miners for months or years. Axon solves this by leveraging Solana's low-transaction fees to make micropayments viable. By bridging BTC rewards to zBTC, we can send instant, near-zero-fee micropayments for every valid share. This unlocks trapped value, makes mining accessible to everyone, and strengthens Bitcoin's decentralization.

Baloteer

Consumer Apps, Infrastructure, Undefined

Balloteer makes voting work in the real world. Most voting systems suck. Board meetings drag on without resolution. Neighborhood associations can’t get quorum. Companies spend weeks collecting feedback that nobody trusts. DAOs are a joke. Traditional tools are either paper-based chaos or bloated enterprise software that costs a fortune — and still doesn’t deliver verifiable results. Balloteer fixes this with technology that actually makes sense: verifiable on-chain voting that ordinary people can access from anywhere. Vote straight from Telegram or WhatsApp. No wallet required for voters — just click a link, cast your vote, and it’s recorded on-chain with cryptographic proof. Organizers get the security of blockchain without forcing everyone through the crypto learning curve.
