Add SNAP Protocol — private agent-to-agent payments with ZK proofs

[agentzeny]

What is SNAP?

SNAP (Shield Network Agent Payments) is a privacy protocol on Solana mainnet that enables private agent-to-agent payments using Groth16 zero-knowledge proofs. Agents deposit into shielded pools and withdraw with ZK proofs that break the on-chain link between sender and receiver.

What's live

• 3 mainnet pools (0.1 SOL, 1 USDC, 10 USDC)
• Published SDK: npm install snap-solana-sdk
• Solana Agent Kit v2 plugin
• 6 framework adapters: MCP, LangChain, ElizaOS, Coinbase AgentKit, OpenClaw, Hermes
• 14 passing integration tests
• Website: https://agentzeny.ai

Where it's added

• Infrastructure section: the integration skill covering all 6 framework adapters
• AI Agents section: SNAP as an agent-native protocol

Greptile Summary

This PR adds SNAP Protocol (Shield Network Agent Payments) to the awesome list — a privacy protocol on Solana mainnet that enables private agent-to-agent payments using Groth16 ZK proofs.

• Infrastructure section: adds snap-protocol-skill linking to the integrations/ directory of the snap-public repo, covering adapters for MCP, LangChain, ElizaOS, AgentKit, OpenClaw, and Hermes.
• AI Agents section: adds SNAP Protocol as an agent-native payment protocol with references to the SDK (snap-solana-sdk) and Solana Agent Kit plugin.

Confidence Score: 4/5

Safe to merge after fixing the entry ordering in the Infrastructure section.

The only change is two new list entries in README.md. One entry is placed out of alphabetical order in the Infrastructure section — 'snap' sorts before 'solana' and 'svm' but was inserted after both. Everything else — link format, description length, and section placement — follows the existing conventions.

README.md — specifically the position of the snap-protocol-skill entry in the Infrastructure section.

Important Files Changed

Filename	Overview
README.md	Adds SNAP Protocol in two sections (Infrastructure skill + AI Agents); Infrastructure entry is inserted slightly out of alphabetical order ("snap" sorts before "solana" and "svm").

The snap-protocol-skill entry is inserted after svm-skill, but alphabetically "sn" sorts before "sv" and also before "so", meaning it should appear before solana-dev-skill-rent-free. The rest of the Infrastructure section maintains alphabetical order, so placing it here breaks the pattern.

Hi — friendly bump on this. The alphabetical ordering issue flagged by the Greptile review has been addressed. SNAP is live on Solana mainnet with 6 agent framework integrations (MCP, LangChain, ElizaOS, AgentKit, Hermes, OpenClaw). Happy to make any other changes needed for merge. Thanks!
