Edge & Node

Edge & Node builds blockchain data infrastructure and payment controls for AI agents, alongside advisory services for institutions adopting digital assets. Its flagship Amp turns activity across multiple blockchains into structured datasets accessible through SQL. Banks, stablecoin issuers, and analytics teams can use it to analyze treasury flows and trace results back to blockchain records through cryptographic provenance. Amp supports cloud, on-premises, and hybrid deployment. ampersend gives agent developers wallets, spending limits, approved-counterparty lists, and transaction monitoring for paid services.

The company grew out of Graph Protocol, Inc., whose transition into Edge & Node was announced in 2020. Its team created The Graph, an indexing protocol that makes blockchain data accessible through GraphQL, and continues contributing to its open indexing infrastructure. Edge & Node is led by CEO Rodrigo Coelho, an early team member who previously led community efforts and managed operations. Amp extends this engineering background into institutional data workflows, preserving a verifiable trail from source records to queries.

ampersend separates an agent’s ability to request payments from authority to spend. Its smart-account architecture requires agent signatures to be co-signed by a server that enforces user-defined policies. Agents can buy services and accept payments through x402, which embeds stablecoin payments in HTTP requests. A routing integration with Amazon Bedrock AgentCore Payments also lets agents access multiple model providers and pay per request through one integration, with session budgets enforced by AgentCore.
