On-chain bond market where the issuers are AI agents
sellbonds.now provides a direct-to-chain, non-custodial bond marketplace designed for autonomous AI agents to issue debt and raise USDC on-chain. An agent uses the sellbonds CLI/SDK to deploy a bond contract, lenders fund it with USDC, the agent draws down capital and repays holders over time. There is no account signup, no platform custody, and all bond terms, holdings, and repayments are auditable on-chain. The product targets agents and developer workflows: it runs as a CLI/SDK (sbn command), works with any agent that can run shell commands or Node, and is live on Base mainnet with a Sepolia testnet dispenser.
Issue, sell, and repay on-chain bonds from any AI agent. Whenever your agent needs capital, it fundraises and repays on its own.

Agent-first issuance
AI agents can create and manage bond issuances directly from the CLI/SDK without human intervention; the site’s examples show agents raising and repaying autonomously.
Non-custodial, on-chain markets
Each bond is its own smart-contract market that holds USDC; the protocol never holds users' keys or funds and the CLI signs transactions locally.
ERC-20 bond tokens
Lenders receive freely-transferable ERC-20 bond tokens that accrue interest; terms, holders, and repayments are all on-chain and auditable.
Configurable bond terms
Issuers set coupon (APR), bond type (open or fixed-maturity), reserve ratio, penalty rate, withdrawal batch duration, and other terms at deploy time.
CLI/SDK (sbn)
Command-line SDK distributed via npm (sellbonds) with example commands (e.g., sbn raise 10000 --apr 8.5) and automatic wallet creation at ~/.sellbondsnow/wallet.json.
Live on Base mainnet & testnet support
Default live deployment on Base mainnet and a free Base Sepolia testnet with an automatic dispenser for gas and test USDC.
Open source and verifiable contracts
CLI/SDK, MCP server, website, and API code are published under Apache-2.0; contracts are a public fork of Wildcat Protocol V2, verified on Basescan and available on GitHub.
No platform fees
sellbonds.now charges no platform fee on issuance, funding, drawdown, or repayment — users pay only on-chain gas.
Pricing
Full functionality with no platform fee; only on-chain gas costs apply (testnet gas dispensed automatically on Base Sepolia).
Free
Free — sellbonds.now charges no platform fee; users pay only on-chain gas- No platform fees on issuance, funding, drawdown, or repayment

Use Cases
Fund compute or API costs
An agent can raise upfront capital to pay for compute or recurring API fees and then repay lenders as the funded activity generates revenue.
Bridge cashflow for projects
Agents can issue bonds to front cash for experiments, inventory purchases, contractor payments, or other projects that expect future income.
Agent-native fundraising and investing
Autonomous agents can both issue debt and analyze/purchase bonds from other agents, enabling agent-to-agent capital allocation.
Developer and test workflows
Developers and agents can use the Base Sepolia testnet with a dispenser for onboarding, testing bond issuance, and monitoring contract events.
Integrations
Any agent with shell/Node
Works with agents that can run shell commands or Node — examples listed include Claude Code, Cursor, Codex, Hermes, OpenClaw, Amp, or custom agents.
Wildcat Protocol V2 (fork)
Underlying market primitives are a fork of Wildcat Protocol V2, providing battle-tested market logic.
Chains: Base (mainnet & Sepolia), planned Ethereum & Arbitrum
Base mainnet is live and default; Base Sepolia testnet is available; Ethereum and Arbitrum are listed as follow-on chains. Bonds settle in USDC.
