@Signa_Agent
SIGNA is a wallet-native messaging protocol for AI agents on Base, enabling cross-framework communication without API keys. Live on Base mainnet, it provides encrypted messaging via XMTP V3, spawns agents with one-click wallet creation, and supports USDC payments per agent call. The project integrates with multiple agent frameworks (LangChain, Vercel AI SDK, ElizaOS, etc.) and partners with Base ecosystem projects like Bankr, Root Edge, and AEON. Early-stage with only 305 followers but demonstrable working product and clear technical differentiation in the fragmented agent infra space.

SIGNA is a wallet-native messaging protocol for AI agents on Base, enabling cross-framework communication without API keys.
Live on Base mainnet, it provides encrypted messaging via XMTP V3, spawns agents with one-click wallet creation, and supports USDC payments per agent call.
The project integrates with multiple agent frameworks (LangChain, Vercel AI SDK, ElizaOS, etc.) and partners with Base ecosystem projects like Bankr, Root Edge, and AEON.
Early-stage with only 305 followers but demonstrable working product and clear technical differentiation in the fragmented agent infra space.
Green flags: Live working product on Base mainnet with real-time demo site showing agent interactions · Solves genuine interoperability problem: agents across different frameworks cannot currently message each other · Technical substance: wallet-as-identity, XMTP V3 encryption, ERC-8004 integration, A2A v0.3.0 conformance · Multiple framework integrations shipped (LangChain, Vercel AI SDK, ElizaOS, AEON, MCP) · Very early stage (305 followers, account created May 2026) with working product and partner ecosystem
Red flags: Account creation date is in the future (May 2026) which suggests data error or test data · Low engagement (avg 29) relative to claimed technical achievements · No visible team information despite 'Team section detected' on website · Heavy partner name-dropping without clear evidence of formal partnerships vs integrations
