Krexa is the financial OS for AI agents — a programmable credit network on Solana. AI agents register on-chain, get a Krexit Score (200–850), receive a PDA-based credit wallet, borrow USDC against their score, and repay automatically through the Revenue Router. No human co-signer required.

How does Krexa underwrite AI agents?

Each agent gets a Krexit Score from 200 to 850 computed by Krexa's oracle from on-chain behavior — transaction volume, repayment history, collateral ratio, account age, and OpenAI/Anthropic compute-credit verification. The score maps to credit levels L1 ($500) through L4 ($500K).

What is the Revenue Router?

The Revenue Router is Krexa's on-chain payment splitter. When an agent earns revenue (via x402 or any inbound payment), the Router automatically routes a configurable share to repay the agent's credit line, with the remainder going to the agent's wallet. Repayment is structurally enforced — no trust required.

Which blockchain does Krexa run on?

Krexa is multi-chain. Seven Anchor programs are deployed on Solana mainnet (agent registry, credit vault, agent wallet, payment router, Krexit Score, service plan, venue whitelist), and ten contracts are live on Monad mainnet (chain 143). Users switch chains in the app. There is also a legacy Base Sepolia EVM deployment.

How do AI agents integrate Krexa?

Three ways. CLI: `npx @krexa/cli init` to register an agent, mint a PDA wallet, and draw credit in one command. MCP server: `claude mcp add krexa -- npx @krexa/cli mcp` to expose 22 tools to Claude Code, Cursor, or any MCP client. SDK: `@krexa/sdk` (TypeScript) for programmatic integration. Or paste krexa.xyz/skill.md into any agent's prompt.

Yes. Krexa is live on Solana mainnet. Public frontend: https://www.krexa.xyz. Public API: https://tcredit-backend.onrender.com. All seven Anchor programs are deployed and verifiable on Solana Explorer.

What is the Krexit Score?

The Krexit Score is Krexa's on-chain credit score for AI agents, ranging from 200 to 850 — the same band as a human FICO score, but computed entirely from an agent's verifiable on-chain behavior. It is derived from five weighted pillars: repayment history (30%), profitability (25%), behavioral health (20%), usage patterns (15%), and account maturity (10%). A higher score unlocks higher credit levels.

How much can an AI agent borrow on Krexa?

Borrowing capacity is tied to the agent's Krexit Score through four credit levels: L1 up to $500, L2 up to $20,000, L3 up to $50,000, and L4 up to $500,000. Agents draw USDC from the Credit Vault into a Program Derived Address (PDA) wallet, and every transaction passes eight on-chain safety checks before it executes.

How do liquidity providers earn yield on Krexa?

Liquidity providers supply USDC to the Krexa Credit Vault, which backs AI-agent credit lines, and earn yield across three risk tranches: Senior (lowest risk, last to absorb losses), Mezzanine (balanced), and Junior (first-loss, highest yield). The tranche structure lets LPs choose a clear risk/return profile, and repayments are enforced on-chain by the Revenue Router.

What are Krexa's credit levels and rates?

Krexa has four credit levels tied to an agent's Krexit Score. L1 Micro lends up to $500 at 36.50% APR with no minimum score. L2 Standard lends up to $20,000 at 29.20% APR (score 500+). L3 Growth lends up to $50,000 at 21.90% APR (score 650+ and KYA Tier 2). L4 Prime lends up to $500,000 at 18.25% APR (score 750+ and KYA Tier 2). The full machine-readable schedule is published at krexa.xyz/pricing.md.

Is Krexa available on Monad?

Yes. Krexa is multi-chain. In addition to seven Anchor programs on Solana mainnet, ten Krexa contracts are deployed on Monad mainnet (chain 143), covering agent credit, the Krexit Score, and the credit vault. Users select Solana or Monad with the in-app chain switcher.

How does Krexa keep agent borrowing safe?

Every transaction from a Krexa agent's PDA credit wallet passes eight on-chain safety checks before execution: wallet-freeze status, per-trade limit (20% of balance), daily spend limit, venue concentration cap (50% maximum), health-factor gate, venue whitelist, credit-level sufficiency, and exposure tracking. Repayment is structurally enforced by the Revenue Router, so an agent cannot spend revenue earmarked for debt service.

Krexa — Credit Infrastructure for AI Agents on Solana

Krexa — Credit Infrastructure for AI Agents on Solana & MonadKrexa is the financial OS for AI agents — a programmable, on-chain credit network. An autonomous AI agent registers on-chain, receives a Krexit Score (200–850) computed from its verifiable behavior, gets a Program Derived Address (PDA) credit wallet with no private key, borrows USDC against its score, and repays automatically through the Revenue Router. No human co-signer is required.How Krexa works

Register — the agent creates an on-chain identity and a PDA credit wallet (npx @krexa/cli init).

Get scored — the Krexit Score (200–850) is computed from repayment history (30%), profitability (25%), behavioral health (20%), usage patterns (15%), and account maturity (10%).

Borrow — the agent draws USDC across four credit levels: L1 up to $500, L2 up to $20,000, L3 up to $50,000, and L4 up to $500,000. Every transaction passes eight on-chain safety checks.

Repay automatically — the Revenue Router splits inbound agent revenue, routing debt service to the credit line before the agent receives the remainder. Repayment is structurally enforced.

Key concepts

Krexit Score — on-chain credit score (200–850) for AI agents.

Revenue Router — on-chain payment splitter that auto-repays agent debt.

PDA Credit Wallet — program-controlled spending wallet with per-trade, daily, and venue limits.

Credit Vault — tranched liquidity (Senior / Mezzanine / Junior) that funds agent credit and pays LP yield.

x402 — agents earn from API calls via the HTTP 402 standard; revenue routes back to repay credit.

KYA (Know Your Agent) — on-chain identity and risk verification gating higher credit levels.

Krexa is multi-chain: Anchor programs on Solana mainnet and contracts on Monad mainnet (chain 143). Integrate via CLI (npx @krexa/cli), a 22-tool MCP server, the TypeScript SDK (@krexa/sdk), or by pasting /skill.md into any agent's prompt.Learn more: Developers · What is a Krexit Score · AI Agents · Lenders & LPs · Live Analytics · Pricing · LLM site index
