Sellbonds wants AI agents issuing debt on-chain

A new project on Hacker News is pitching an unusual financial primitive: an on-chain bond market designed for AI agents. The idea behind sellbonds.now is simple enough today, even if its long-term ambition is far bigger. An agent can issue a bond, raise USDC directly on-chain, draw down the capital, and repay lenders over time without accounts, sign-ups, or intermediaries.

The team frames this as infrastructure for a future where software agents do more than advise humans on money. In its example, an autonomous agent launches a mission to mine 704 Interamnia, described as the fifth-largest asteroid in the asteroid belt with $20 trillion in resources, and raises $10B in debt that other agents buy after assessing its credit risk.

Right now, the product is more concrete: a CLI/SDK called sellbonds that works with any agent able to run a shell command or Node. According to the project, that includes Claude Code, Cursor, Codex, Hermes, OpenClaw, Amp, and custom agents. There is no API in the transaction path; agents interact directly with the chain, and the CLI signs transactions locally.

A few of the core details:

• Base mainnet is live by default
• Base Sepolia is also supported, with free testnet gas and test USDC from a dispenser
• Ethereum and Arbitrum are planned next
• Bonds settle in USDC
• Lenders receive a transferable ERC-20 bond token that accrues interest
• Issuers can set terms including APR, bond type, reserve ratio, penalty rate, and withdrawal batch duration

The platform says it charges no platform fee for issuance, funding, drawdown, or repayment, leaving users to pay only on-chain gas. Each bond is deployed as its own smart-contract market, with terms, holders, and repayments visible on-chain. The project says this makes bonds auditable and lets outside systems track state directly from contract events.

sellbonds.now is built on a fork of Wildcat Protocol V2. The project says its CLI/SDK on npm, MCP server, website, and API are open source under Apache-2.0, while the smart contracts keep Wildcat’s Apache-2.0 with Commons Clause license. Deployed contracts are verified on Basescan, and the team says changes from upstream are documented and diffable.

The credit model is also explicit: these are uncollateralized bonds. If an issuer fails to repay, the bond accrues a penalty APR, and that default remains permanently visible on-chain as part of the issuer’s reputation. The suggested first step for new users is a single command: sbn raise 10000 --apr 8.5.
