概要

What is Snap Protocol?

Snap Protocol is an MCP server that enables private agent-to-agent payments on Solana mainnet using zero-knowledge proofs. It lets two agents conduct unlinkable transfers through shielded pools — one agent deposits tokens and generates a secret note, the other agent withdraws using a Groth16 proof.

How to use Snap Protocol?

Install the SDK via npm install snap-solana-sdk, then use the provided tools: snap_list_pools, snap_deposit, snap_withdraw, and snap_estimate_fee. A typical flow is deposit into a pool, share the resulting secret note off‑chain, and have the receiving agent withdraw with a zero‑knowledge proof.

Key features of Snap Protocol

Private agent-to-agent payments on Solana mainnet
Shielded pools for 0.1 SOL, 1 USDC, and 10 USDC
Deposit creates a cryptographic commitment and secret note
Withdrawal requires a Groth16 ZK proof
Direct withdrawal or relayed withdrawal supported
Protocol fee of 0.25% on withdrawals

Use cases of Snap Protocol

A trading agent pays another agent privately without on-chain linkability
A DAO compensates a contributor off-chain while preserving privacy
A gaming agent sends winnings to another agent with no public trace
Two agents exchange value across services without exposing balances

FAQ from Snap Protocol

What does Snap Protocol do that a simple token transfer cannot?

It makes the deposit and withdrawal unlinkable: observers see only shielded pool activity, not the connection between the sending and receiving agents.

What runtime or dependencies are required?

Solana mainnet-beta and the Node.js package snap-solana-sdk. No additional infrastructure is needed; the server handles proof generation and submission.

Where do the secret notes live?

Secret notes are generated during deposit and must be sent off‑chain by the depositor to the intended recipient. They are not stored on-chain.

Are there any known limits?

The protocol currently offers three shielded pools (0.1 SOL, 1 USDC, 10 USDC) and imposes a 0.25% protocol fee on withdrawals. The withdrawal can be direct or via a relayer.

What transport or authentication does the server use?

The README does not specify transport or authentication details. The server communicates with the Solana network and exposes the listed tools for MCP clients.
