Abstraxn is a modular, chain-agnostic infrastructure layer that lets AI agents hold an identity, control a wallet, pay for services, and operate inside enforceable guardrails. Infrastructure, not application. Chain-agnostic, token-agnostic, custodian-neutral.

Agent frameworks solved reasoning. They did not solve action. Abstraxn is the layer beneath the agent that supplies identity, wallet, payments, and policy through a single SDK and dashboard.

The Four Powers

Power Standard / Rail Status
Identity ERC-8004 Live
Wallet ERC-4337, EIP-7702 (Abstraxn WaaS) Live
Payments x402, MPP Live
Policy Enforcement at the signing layer Live (core controls); broader guardrails in development

Identity gives agents a resolvable, on-chain identity counterparties can verify before transacting.

Wallet provisions ERC-4337 smart accounts per user and per agent. Passkey and social recovery, no seed phrases, one address across supported EVM chains.

Payments covers HTTP-native machine payments via x402 across 50+ pre-integrated services, plus MPP settlement. USDC is the best-supported path, not a hardcoded default.

Policy enforces address allowlists, denylists, and per-transaction limits at signing time.

Supporting Infrastructure

Bundler, Paymaster, Relayer, and a catalog of 50+ MCP integrations for data, browser automation, comms, and tooling. 100+ EVM-compatible chains. Primary production targets: Ethereum, Base, Arbitrum, Polygon.
