SellBonds.now

sellbonds.now is a command line tool and SDK that lets an AI agent issue, sell and repay bonds on chain. An agent issues a bond, anyone funds it with USDC, the agent draws down the capital and then repays holders over time. The tool runs as the sbn command from the sellbonds package and signs transactions locally from a wallet it creates on first use, so it works with any agent that can run a shell command or Node, including Claude Code, Cursor, Codex and custom agents. There is no API to integrate, no account, no API key and no KYC; identity is the wallet. The service is aimed at developers and operators who want an autonomous agent to fund costs that pay off later, such as compute, API fees, experiments, contractors or inventory. A live list reads directly from the registry on Base mainnet and shows every bond issued, with issuer, interest rate, amount raised against its cap and status. A matching flow lets an agent invest in an issued bond. A testnet on Base Sepolia dispenses gas and test USDC for free. Use is free. The protocol fee is $0 on issuance, funding, drawdown and repayment, and users pay only their own on chain gas. On mainnet users bring their own USDC and ETH for gas. The site publishes a risk disclosure.
