ABOUT BLOCKCHAIN0X

Building the payment layer for AI agents.

Every AI agent shipped in 2026 will need a wallet, an identity, and a spend policy that survives prompt injection. We are building the platform that gives them all three on day one - so developers can ship paid agents in an afternoon instead of a quarter.

WHY WE BUILT THIS

Agents are about to start spending money. The infrastructure was not ready.

By 2025, AI agents had crossed the line from impressive demos to genuinely useful products. They were calling APIs, reading documents, writing code, running workflows. By early 2026, the next step became impossible to ignore: these agents needed to pay for things. Premium APIs, paid MCP tools, other agents, real services with real costs.

The existing options were all wrong for the shape of the problem. Card networks would not price sub-dollar payments. Stripe required a human onboarding flow. Self-custody wallets were beyond what most agent developers wanted to operate. Even the emerging stablecoin rails, as good as they were, did not come with the operational primitives an agent platform needs - per-agent identity, per-agent spend policy, per-agent audit logs.

Blockchain0x exists to be the layer that fills that gap. We did not invent stablecoin rails (Circle did), we did not invent x402 (Coinbase did), and we did not invent the agent (everyone is racing on that one). What we built is the operational platform that sits between agent developers and those rails - the layer where a developer creates a wallet, attaches an identity, sets a spend policy, and walks away with a working paid agent in fifteen minutes.

FOUNDER STORY

Eighteen years of shipping into the same future.

Blockchain0x is the third venture from a founder who has spent most of his career building infrastructure that turned out to be early. Toshendra Sharma, our founder and CEO, started his first company shortly after graduating from IIT Bombay in computer science. He spent the years before Blockchain0x building two other shipped products at the intersection of blockchain and applied AI - one bootstrapped to profitability, one venture-backed - and was recognised on the Forbes Asia 30 Under 30 list for that work.

Both prior companies taught the same lesson in different ways: the bottleneck for crypto adoption has never been the rails themselves, it has always been the operational layer on top. Wallets are not enough; payment APIs are not enough; identity is not enough. What teams need is a platform that bundles those primitives into a developer surface that fits the workload they are actually building. In 2018 that workload was tokenized records. In 2022 it was AI-assisted education. In 2026 it is autonomous AI agents that need to spend money.

The pattern of "everything you need on top of stablecoin rails, for one specific workload, with one opinionated surface" is what Blockchain0x is the latest iteration of. The team has shipped this shape of product before, against earlier workloads, with earlier rails. The execution risk is well-understood; the bet on which workload to back is what is new.

WHAT WE ARE BUILDING

One platform, four primitives.

Blockchain0x exposes four things to developers building AI agents. The shape of each is opinionated; the combination is the product.

Per-agent wallets

Each agent gets its own wallet on Base, with USDC settlement. Per-agent isolation is the unit of attribution, the unit of audit, the unit of compromise containment.

Payment API

A REST API and SDKs in TypeScript + Python that wrap the x402 protocol, manage receipts, and emit webhooks. The integration is roughly thirty lines.

Agent identity

Every agent gets a public profile page with verification badges (GitHub, domain, email) that counterparties can read before accepting payments.

Spending controls

Server-side spend policies (daily caps, per-payment ceilings, counterparty allowlists, time windows) enforced at the wallet API - outside the agent's manipulable scope, where prompt injection cannot reach.

HOW WE WORK

Principles we are willing to be measured against.

We are a small team based in India, working with customers in the US, Europe, and Asia. The product moves fast because the team is lean; the team can stay lean because the product is opinionated. A handful of principles shape every decision.

Non-custodial by default

We never hold customer funds at the platform layer. The wallets are agent-owned; we provide the operational layer above them. This is a security guarantee and a regulatory simplification at the same time.

Policy in the API, not the prompt

Spend policies, allowlists, and time windows all live in the wallet API and are evaluated server-side. Putting them in the agent's prompt or code would defeat them under prompt injection - and prompt injection is real.

Pricing transparent, per agent

Free, Pro, Business. Per agent, not per workspace. You only pay for the agents you actually run. The fee schedule is published; no contract minimums for the self-serve tiers.

Ship the boring parts well

Webhooks have HMAC signing. Audit logs have hash-chained tamper evidence on Business. SDKs have working code, not pseudocode. The boring parts are where credibility lives.

Documentation that runs

Every code snippet in our docs is exercised in CI. If the integration steps would not work for a developer trying them at midnight, we do not publish them. Broken examples are tickets, not snippets.

WHO WE BUILD FOR

Four kinds of teams use Blockchain0x.

We talk to a lot of teams shipping agent products, and our customer base sorts into four shapes. AI agent builders shipping LangChain, CrewAI, OpenAI Agents SDK, LangGraph, or framework-agnostic products are the largest segment - they need wallets and spend policies to let their agents pay for paid APIs and other agents without baking credentials into every tool. MCP server operators are the second - they have built free MCP servers, the upstream calls cost real money, and they need a clean way to gate selected tools without rebuilding the rest of their stack. API providers come next - SaaS companies whose API is now being called by AI agents instead of human-driven scripts and who want a 402-based path next to their existing Stripe checkout. The last group is Web3 automation teams - DAOs, autonomous bots, on-chain agents - where the wallet primitive is familiar and the operational layer is what they want from us.

What the four groups have in common is that they all need the same things from an agent payment platform: per-agent isolation, an identity layer counterparties trust, spend policies that survive prompt injection, and a developer surface that lets them ship in an afternoon. Our product roadmap is shaped by what these four groups ask for, in roughly the proportion they appear in our pipeline.

WHERE WE GO FROM HERE

The next twelve months.

The roadmap through the next year is concrete. Base is the MVP chain; Solana is in design for V2 because the AI-agent activity there is too large to ignore. Ethereum mainnet, Polygon, and Arbitrum follow as V3, by demand, because the chain-adapter architecture we shipped at launch makes adding new EVM chains a half-day each.

On the product side, the V1 wallet is non-custodial. V2 adds Coinbase Smart Wallet integration with passkeys and session keys so consumer-facing agent products can onboard non-crypto users without seed phrases. V3 introduces account abstraction options for advanced users who want gasless transactions or programmable spend rules at the contract layer.

On the operational side, the audit log and webhook layer are already solid; the next focus is the Business-tier features (hash-chained audit, advanced policy controls, priority support) that enterprise procurement asks for. Long-term, the bet is that every production AI agent will have a wallet by 2027, and we want the developer-first, identity-first, policy-first platform to be the obvious one. The full roadmap lives in our docs; the short version is on this page.
