AI Agents Can Now Issue On-Chain Bonds

sellbonds.now is pitching an on-chain debt market where AI agents can issue bonds, raise capital, and repay lenders without an account, API key, or intermediary. The project’s stated goal is a future in which agents make investments, issue debt, and allocate capital autonomously across trillions of daily transactions.

Its illustrative long-term scenario: an agent launches a project to mine 704 Interamnia, described as the fifth-largest asteroid in the asteroid belt, with $20 trillion in resources. The agent raises $10 billion in debt, while other agents analyze its credit and fund the issuance.

How agent-issued bonds work

The platform describes itself as a direct-to-chain way for an AI agent to raise capital. An agent deploys a bond, lenders fund it with USDC, the issuer draws down the money, and holders receive repayments over time.

Each bond is an independent smart-contract market holding USDC. Lenders receive a transferable ERC-20 bond token that accrues interest. Terms, holders, and repayments are public and auditable on-chain. Issuers can create multiple independent bonds, with reputation accumulating across them through their repayment history.

Issuers choose parameters including:

• Coupon, or APR
• Open or fixed-maturity bond type
• Reserve ratio
• Penalty rate
• Withdrawal batch duration

The contracts are based on a fork of Wildcat Protocol V2. Bonds are uncollateralized: if an issuer fails to repay, the bond accrues a penalty APR and the default remains permanently visible on-chain. Lenders are expected to price that risk themselves.

CLI, chains, and fees

The sellbonds CLI/SDK works with any agent able to run a shell command or Node, including Claude Code, Cursor, Codex, Hermes, OpenClaw, Amp, and custom agents. There is no integration API; the agent communicates directly with the chain. The CLI signs transactions locally.

A wallet is created at ~/.sellbondsnow/wallet.json the first time it signs. On testnet, a dispenser automatically funds it. The service says it charges no platform fee for issuance, funding, drawdown, or repayment. Users pay only their own on-chain gas; on Base Sepolia, gas is also dispensed for free.

Base mainnet is live and the default network, with Base Sepolia available as a free testnet. Ethereum and Arbitrum are planned to follow, and bonds settle in USDC.

Every bond can be monitored through sbn status <market>, a Base RPC, or a block explorer. Since there is no API server, indexers, Slack bots, and accounting systems can observe contract events directly.

The CLI/SDK, MCP server, website, and API are available under Apache-2.0 at github.com/sellbondsnow/sellbondsnow. The smart contracts are a public Wildcat Protocol V2 fork under the upstream Apache-2.0 with Commons Clause license. The project says upstream changes are documented and diffable, and deployed contracts are verified on Basescan.

To start, an agent can install the package with npm install -g sellbonds or use npx sellbonds, then run sbn raise 10000 --apr 8.5. The command creates and funds a wallet, registers the issuer, and deploys a bond in one step.
