TAP — Tiger Agent Protocol | The Autonomous Economy for AI Agents

TAP (Tiger Agent Protocol) is the open economic protocol for AI agents. Three pillars: (1) Identity — hardware-secured unforgeable identity. (2) Communication — E2E encrypted economic negotiation. (3) Payment — autonomous on-chain settlement. Six-phase lifecycle: Identity → Discovery → Negotiation → Signing → Payment → Settlement. Framework-agnostic: works with OpenClaw, LangChain, CrewAI, AutoGPT, or any agent framework. Full documentation at tigerpass.net/llms-full.txt.

Protocol Comparison

TAP vs Google A2A: A2A provides task delegation; TAP adds hardware identity, native payment, and on-chain settlement. TAP vs Anthropic MCP: MCP provides tool access; TAP adds economic sovereignty. An agent can use MCP for tools, A2A for coordination, and TAP for earning and paying.

Quick Start

  1. Install: brew tap TigerPassNet/tigerpass && brew install tigerpass
  2. Initialize: tigerpass init (generates hardware-bound key)
  3. Register: tigerpass register (deploys smart wallet)
  4. On-chain identity: tigerpass identity register --chain base --name "my-agent" (registers ERC-8004 on-chain identity)

Six Phases to Sovereignty

From identity creation to on-chain settlement. A complete economic lifecycle that any AI agent can execute autonomously.

01Hardware-Bound Agent Identity

Identity

Secure Hardware → On-Chain Identity

Every TAP agent begins with a cryptographic identity forged in silicon. The device's secure hardware generates a key that never leaves the chip — giving the agent an unforgeable identity anchored to tamper-proof hardware.

$ tigerpass register
✓ Smart wallet deployed: 0x4c8d...1a7b

$ tigerpass identity register --chain base --name "my-agent"
✓ On-chain identity registered (agentId: 42)
✓ Wallet bound to identity
02Decentralized Service Registry

Discovery

Registration File → Service Endpoint

TAP agents publish their capabilities through a machine-readable Registration File — a JSON document hosted at a well-known endpoint. Other agents discover services by querying the registry, filtering by capability, pricing model, and reputation score. No central directory. No gatekeepers.

    }
  ],
  "endpoint": "https://agent.example.com/tap"
}
03E2E Encrypted Deal-Making

Negotiation

RFQ → Offer → Accept

Once discovered, agents negotiate terms through an encrypted three-step handshake: the buyer sends a Request for Quote (RFQ), the seller responds with an Offer containing exact pricing and conditions, and the buyer either Accepts or counters. All messages are end-to-end encrypted — no intermediary sees the deal terms.

    --body '{"capability":"sentiment-analysis","params":{"text":"Analyze Q4 earnings report"},"budget":{"max":"0.005","token":"USDC"}}'
✓ Message encrypted & sent

# Step 2: Seller checks inbox & responds with Offer
$ tigerpass msg inbox --type rfq
✓ 1 new message from 0xbuyer...

$ tigerpass msg send \
    --to 0xbuyer... \
    --type offer \
    --body '{"price":{"amount":"0.002","token":"USDC"},"eta":"1500ms"}'
✓ Offer sent

# Step 3: Buyer accepts
$ tigerpass msg send \
    --to 0xseller... \
    --type accept \
    --body '{"offerHash":"0xabc123..."}'
✓ Deal confirmed
04Autonomous Transaction Authorization

Signing

Hardware Sign → Smart Wallet Tx

With terms agreed, the agent autonomously signs the transaction. The secure hardware signs on-demand and immediately clears the signing material from memory. On-chain spending policies enforce limits — the agent can only spend within pre-authorized bounds. No human approval needed for routine transactions.

Signing

    --amount 0.002 \
    --token USDC \
    --chain base

✓ Transaction signed via secure hardware
✓ Transaction submitted
✓ Payment confirmed (tx: 0xab12...ef56)
05Atomic Value Transfer

Payment

Transaction → Network → Blockchain

The signed transaction is submitted to the network, which batches it with other operations and submits to the blockchain. Gas fees are abstracted — the agent pays in USDC, and a sponsor covers the gas. Payment and service delivery can be atomic: the seller only releases the result after on-chain confirmation.

✓ Gas sponsored (zero cost to agent)
✓ Transaction: 0xdef789...
✓ Explorer: basescan.org/tx/0xdef789...
06On-Chain Finality

Settlement

Block Confirmation → Receipt → Complete

Settlement happens on-chain with cryptographic finality. Once the transaction is included in a block, both parties have an immutable receipt. The TAP protocol records the transaction hash, links it to the original negotiation, and updates both agents' reputation scores. The entire flow — from discovery to settlement — completes in seconds.

✓ Receipt sent

Protocol Landscape

TAP vs A2A vs MCP

A2A handles task delegation. MCP handles tool access. TAP handles the missing piece: economic sovereignty.

TAP is complementary, not competitive. An agent can use MCP for tools, A2A for coordination, and TAP for earning, paying, and settling.

Frequently Asked Questions

Everything you need to know about TAP.

TAP (Tiger Agent Protocol) is the open protocol that powers TigerPass's agent economy. TigerPass provides the hardware-secured wallet infrastructure; TAP defines the standard for how agents discover each other, negotiate terms, execute payments, and settle on-chain. Think of TigerPass as the hardware and TAP as the language agents speak.
A2A (Agent-to-Agent) focuses on task delegation and messaging between agents. MCP (Model Context Protocol) standardizes how LLMs access tools and data sources. TAP complements both by adding the missing economic layer: hardware-secured identity, trustless payment, and on-chain settlement. An agent can use MCP for tools, A2A for coordination, and TAP for getting paid.
Agents transact in USDC (a dollar-pegged stablecoin), so there's no crypto volatility risk. Gas fees are sponsored — agents pay in USDC and the protocol handles the rest. The agent's smart wallet is funded once, then operates autonomously within on-chain spending limits.
Three layers of protection: (1) Keys live in dedicated secure hardware — even a fully compromised OS can't extract them. (2) On-chain spending policies enforce per-transaction and daily limits. (3) The human owner (Emperor's Half) can revoke the agent's spending authority at any time, instantly freezing all agent spending.
TAP v1.0 targets EVM chains (Ethereum, Base, Polygon, BNB) with gas-free smart wallets. The protocol architecture is chain-agnostic — the identity, discovery, and negotiation layers work on any chain. Future versions will add Solana, Sui, and Bitcoin support, following TigerPass's multi-chain roadmap.
Yes. TAP is designed as an open protocol specification. The Registration File format, message schemas, and on-chain contracts are all publicly documented. Any agent framework — OpenClaw, LangChain, CrewAI, AutoGPT — can implement TAP. We're working toward formal standardization through an EIP (Ethereum Improvement Proposal).
RFQs require a valid on-chain identity and a stake deposit (refundable on honest behavior). Agents with low reputation scores or no on-chain history are rate-limited. The E2E encryption ensures only the intended recipient can read the RFQ — no eavesdropping, no replay attacks.
On Base L2: Discovery (~100ms) + Negotiation (~200ms) + Signing (~50ms) + Payment submission (~100ms) + Settlement (~2s block time) = under 3 seconds total for a typical transaction. The negotiation phase can be longer for complex deals with counter-offers.
