402T Labs builds the foundational infrastructure for autonomous systems, seamless value exchange, and large-scale distributed commerce. We create open protocols and reference implementations that enable software agents, organizations, and networks to transact and verify value in a decentralized way—without centralized intermediaries.

A layered system that enables reliable, ordered transaction records over networks with long delays. PoTT gives participants a way to verify the sequence and validity of exchanges where immediate consensus isn't possible.
A cryptographic audit framework that enforces policy-driven transparency for organizational treasuries. TPL makes it feasible to publish verifiable proofs of financial state and compliance while keeping operational details secure.
A practical standard for interface-driven services that goes beyond plain text or data. MCP Apps let services expose structured, secure interaction surfaces, making complex workflows easier to navigate and verify.
An HTTP-native payment and settlement layer that supports instant, low-cost microtransactions between services and agents. x402 turns the web itself into a machine-accessible transaction layer.
Our work makes programmable, auditable, and resilient value exchange possible across a wide range of environments, from high-latency space links to real-time internet services.
Groundbreaking protocols for decentralized transaction systems.

Space-based data centers (SBDCs) place compute and storage in orbit. Recent demonstrations show server-class hardware and GPU payloads can support early edge cloud services. This report reviews the December 2025 state of compute payloads, power, thermal design, and communications, using a quantitative "cost-per-watt" lens to compare orbital and terrestrial deployments.
Novel primitives and architectures for decentralized transactions at scale.
A transport-layer receipt primitive that cryptographically chains hop-timed custody attestations to Bitcoin payload hashes. Each relay appends a signed receipt with ingress/egress timestamps, creating tamper-evident propagation histories for dispute resolution.
An optimization strategy that prioritizes block headers for efficient chain synchronization across intermittent, high-latency links. Headers enable timely fork choice decisions while deferring transaction and filter data to opportunistic transfers.
Lightning Network channels parameterized for interplanetary delays, incorporating one-way light time and jitter allowances into CLTV/CSV timelocks. Channels maintain capital efficiency while accounting for physics-based settlement delays.
A rigorous security profile requiring multi-path, multi-domain evidence with independent time-beacon audits. Ensures administrative diversity and OWLT envelope compliance for high-stakes dispute resolution.
Treasury Proof Ledger (TPL) models a Bitcoin treasury as a conserved state machine over multiple domains, tracking on-chain and off-chain exposures with an explicit fee sink for miner payouts and slippage.
TPL creates cryptographic logs that support stakeholder-specific views: regulators, auditors, boards and the public each see only the policy-allowed slice of treasury exposure, anchored on Bitcoin for non-equivocation.
A cryptographic audit framework that enforces policy-driven transparency for organizational treasuries.
Transaction architectures that maintain verifiability across extreme network conditions, from Earth to off-planet domains. Our work enables reliable value exchange across AU-scale, intermittently connected links.
An HTTP-native payment and settlement layer that supports instant, low-cost microtransactions between services and agents.
At 402T Labs, we develop solutions and conduct research about this protocol.
We work with enterprise partners, institutions, and open-source communities to prototype the infrastructure for the next generation of value systems—designed first for autonomous services, built for the web, and capable of extending beyond Earth.
