Aleo is a Layer 1 blockchain that uses zero-knowledge proofs to enable private, scalable decentralized applications. Unlike traditional blockchains where validators execute every transaction, Aleo offloads smart contract execution off-chain through a Prover Market, allowing users to hide transaction details while processing thousands of transactions per second. The platform combines general-purpose programmability with privacy by default, differentiating itself as one of the first blockchains to leverage zero-knowledge technology for both privacy and scalability.

RedotPay is a stablecoin-based fintech platform that combines crypto payment cards, cross-border payout rails, and multi-currency accounts into a unified financial app. It serves consumers in emerging markets facing currency instability and limited banking infrastructure by enabling global spending and transfers using cryptocurrencies without fiat conversion. With 6+ million users across 100+ countries and $10B+ annualized payment volume, RedotPay has achieved unicorn status ($1B+ valuation) in under 3 years, backed by tier-one investors including Lightspeed, Coinbase Ventures, and Goodwater Capital.

⚠️ INACTIVE: Prime Trust was a technology-driven trust company that provided API-based financial infrastructure for fintech and digital asset companies, offering custody, funds processing, compliance, and transaction settlement services. The company served nearly 700 B2B clients including Swan, Abra, Dapper Labs, and Binance US. Prime Trust filed for Chapter 11 bankruptcy in August 2023 and is no longer operating.

Aztec is a privacy-first Layer 2 rollup for Ethereum that enables encrypted transaction execution and private smart contracts while maintaining public verifiability through zero-knowledge proofs. Unlike privacy blockchains like Zcash, Aztec is programmable—developers can specify privacy at granular levels (users, data, metadata, or full contract logic) using the Noir language. It uses client-side proof generation to keep sensitive data off centralized servers, enabling institutions and users to conduct confidential DeFi operations on Ethereum.
