The compliance layer for the agent economy

AI agents move money.We make that safe.

TavSin is a policy-enforced smart wallet for autonomous AI agents on Solana. Spending limits, vendor allowlists, and daily budgets are enforced on-chain— agents can’t bypass them. Every transaction emits a tamper-proof audit entry. Plugs into Claude Desktop, Cursor, and any MCP client. The regulatory unlock for enterprises deploying agent fleets.

Live LLM Demo

Plug into Claude Desktop.Watch policy enforce in real time.

TavSin ships as an MCP server with 7 tools. Connect it to Claude, Cursor, or any MCP client. Ask the LLM to spend USDC. Watch the program approve small payments, deny oversized ones, and hit the daily budget — every decision logged on devnet.

Protocol Model

Designed like infrastructure, not marketing theatre.

The best crypto protocol homepages feel like they are exposing an operating model. TavSin should do the same: clear system design, visible risk posture, and credible execution language.

01

Capital sits in protocol-controlled wallets

Funds do not live in the agent. TavSin holds custody in a PDA wallet derived from owner and agent identity.

02

The agent requests execution, not custody

The model can initiate spend requests, but the protocol enforces amount, budget, time, program, and freeze status.

03

Every decision becomes visible state

Approved and denied transactions are logged as protocol records, turning agent behavior into auditable infrastructure.

Control Modules

Every wallet behaves like a programmable mandate.

Instead of selling abstract “AI safety”, TavSin defines concrete financial controls at the wallet layer. That is what makes the product feel credible in a crypto context.

POLICY RAILS

Spending Policies

Per-transaction ceilings, rolling budgets, allowlists, and time windows enforced directly by the program.

AGENT OPS

Agent Autonomy

Agents move capital inside hard constraints instead of waiting for manual approvals or multisig babysitting.

RISK CONTROL

Kill Switch

Freeze a wallet instantly when model behavior, market conditions, or integrations stop looking safe.

VERIFIABILITY

On-Chain Audit Trail

Every approval and every denial is logged on-chain so operators can inspect real behavior, not promises.

EXECUTION

Solana Speed

Sub-second rule checks keep agent execution fast enough for real on-chain workflows and payment loops.

LIVE GOVERNANCE

Live Policy Updates

Adjust limits and permissions in production without replacing wallets or redeploying core infrastructure.

Start Here

Build agent finance with the visual language of a serious protocol.

TavSin is not another AI wrapper. It is wallet infrastructure for teams that need autonomous execution without surrendering financial control.

The Missing Layer

Squads is for human multisig. TavSin is for autonomous agents.

Squads protects against bad humans. TavSin protects against bad inference. Different threat model, different primitives — agent identity, MCP-native tooling, shared blocklist registry, on-chain reputation graph.

325+ Solana AI projects. Thousands of MCP tool servers. x402 standardizing agent payments. Zero projects built the wallet governance layer — until now.

Competitive Landscape

Everyone built the rails. Nobody built the controls.

We studied every project in the Solana AI agent stack. Payment rails exist. Wallet governance does not. TavSin fills the gap.
