ACTIVATING BITCOIN'S IDLE CAPITAL

Bitcoin's Agentic Execution Layer

Tachi enables institutions and AI agents to run smart contracts and earn yield on self-custodial Bitcoin - without bridges, wrapped tokens, or custodians.

Core Capabilities
for Bitcoin's Next Era

Post-Quantum Safety

Cryptographic primitives built for the post-quantum era. Threshold signatures and quantum-resistant cryptography at the protocol layer.

Programmable DeFi Primitives

Native yield, lending, trading, and smart contracts on Bitcoin - making sats programmable without bridges, wrappers, or custody tradeoffs.

AI Centricity

Infra for autonomous agents to transact, optimize, and settle on Bitcoin natively. AI-native architecture from the ground up.

Building Bitcoin's Agentic Economy
Across Three Horizons

Horizon 1

TVL Repatriation

Agentic yield aggregation across native Bitcoin protocols with self-custodial vaults.

Tachi becomes the single interface for optimized BTC yield.

TVL Repatriation
Horizon 2

Capital Efficiency

BTCfi SDK for custom institutional yield strategies.

DeFi primitives (lending, trading, structured products) running on Bitcoin's own security model.

Capital Efficiency
Horizon 3

Universal Programmability

Full SatVM on Bitcoin Mainnet.

Any smart contract, any runtime, any agent running on actual Satoshis. The BTC-native economy goes live.

Cryptographic Breakthroughs

After 18+ months of R&D, we arrived at these breakthroughs that enable Tachi to power programmability for agents natively on Bitcoin.

TAURUS Signature Scheme

Secure onboarding with distributed trust and full self-custody: no bridges, no custodians.

SatVM Modular Runtime

Multi-runtime programmability (EVM, Wasm, Script) natively secured by Bitcoin.

Hash Accumulated Txn Proofs (HAT)

Verifiable receipts for every offchain Bitcoin transaction, ensuring integrity and instant settlement.

Recursive Inclusion Proofs (RIPs)

Aggregated proofs anchored to Bitcoin L1, enabling finality, auditability, and trustless verification.

Architecture

The Tachi Flow

Tachi's n-tier architecture is designed to derive maximum utility from Satoshis

Tachi architecture diagram

Your Sats are securely onboarded onto Tachi via TAURUS — no bridges or custodians.

1

Onboarded Sats are virtualized into VTXOs (Virtual UTXOs), activating them for programmable use.

2

Your Bitcoin becomes seamlessly usable across native, high speed BTC apps — each txn generating verifiable proofs.

3

These proofs are aggregated into a Recursive Inclusion Proof, creating a single verifiable state of all activity on Tachi.

4

The validated state is immutably anchored back to the Bitcoin mainnet for final settlement, preserving security & ensuring full auditability.
