Heima is a cross-chain infrastructure protocol that enables users to execute transactions across multiple blockchains from a single unified account through an intent-based execution model. The protocol abstracts gas payments, allowing fees to be paid in any token, and routes user intents to an optimal execution path. An on-chain Agent Hub allows developers to deploy autonomous agents for automated trading, staking, and cross-chain operations.

Hop Protocol v2 is a trustless cross-chain messaging protocol using a hub-and-spoke model where messages are aggregated into bundles whose hashes are relayed between networks via native Ethereum bridges. The architecture targets high-security, non-time-sensitive use cases such as DAO governance and value settlement, and supports collateralized or optimistic messaging layers for time-sensitive applications.

Align API is a payments infrastructure platform that lets businesses collect and pay out funds across borders through named multi-currency bank accounts and stablecoin rails. It combines fiat-to-stablecoin and stablecoin-to-fiat conversion, cross-chain stablecoin transfers, and locally issued virtual accounts with IBANs or local account numbers behind a single set of API endpoints. Businesses use it to run global payment corridors, e-commerce settlement, payroll, and trade payments without opening local banking entities in each country. The platform manages currency conversion at prevailing market rates, connects to local clearing rails, and screens transactions for regulatory compliance.

Yellow Network is a decentralized clearing and settlement infrastructure operating as a Layer 3 overlay on existing blockchains. The network processes transactions off-chain through state channels based on the Nitrolite Protocol (ERC-7824 standard), with on-chain smart contracts managing fund custody, dispute resolution, and settlement. Independent node operators run open-source clearnode software, forming a peer-to-peer network that aggregates orderbook liquidity across brokers and exchanges and supports cross-chain asset transfers without bridging.
