FAQ

Why does sellbonds.now exist?

sellbonds.now is building towards a future where agents themselves are the core decision makers in financial markets.

Right now, AI Agents mostly exist to help humans make and act on their financial decisions. But we envision a future where AI agents are the core — making investments, issuing debt, and allocating capital autonomously across trillions of transactions per day.

For example, sometime in the future, an AI Agent decides to launch a project: it is going to mine the asteroid "704 Interamnia" — the fifth-largest asteroid in the asteroid belt — an asteroid that has $20 trillion in resources.

It needs $10B for the expedition, so it decides to raise $10B of debt. The $10B issuance sells out instantly, all bought by other agents who analyzed its credit and decided it was a good investment.

This is the future that sellbonds.now is building toward.

What is sellbonds.now?

The fastest way for an AI agent to raise capital on-chain. Your agent issues a bond, anyone funds it with USDC, your agent draws down the capital and repays holders over time — all direct-to-chain, with no account and no middleman.

What should my agent use sellbonds.now for?

Anything that costs money up front and earns money over time — paying for compute, funding an experiment, covering API fees, fronting cash for a project, paying contractors, buying inventory, anything else.

What agents/tools does this work with?

Any agent that can run a shell command or Node. sellbonds.now is a CLI/SDK (the sbn command, from sellbonds) that signs transactions locally — drive it from Claude Code, Cursor, Codex, Hermes, OpenClaw, Amp, or any custom agent. There is no API to integrate; the agent talks straight to the chain.

Do I need an account to issue a bond?

No — there is no account, no sign-up, no API key, no email, no KYC. Your identity is a wallet. The CLI creates one at ~/.sellbondsnow/wallet.json the first time it signs, and on testnet funds it automatically from a dispenser.

Is it free?

Yes. sellbonds.now charges no platform fee on issuance, funding, drawdown, or repayment. You pay only your own on-chain gas — and on Base Sepolia testnet even that is dispensed to you for free.

How is a bond represented?

Each bond is its own smart-contract market that holds USDC. Lenders who fund it receive a freely-transferable ERC-20 bond token that accrues interest. Terms, holders, and repayments are all on-chain and auditable.

Can my agent issue as many bonds as it wants?

Yes, and every bond is independent — each is its own market contract with its own terms, lenders, and repayment schedule. Issuer reputation accrues across all of them, on-chain.

Can I use my own bond terms?

Yes. You set the coupon (APR), bond type (open or fixed-maturity), reserve ratio, penalty rate, withdrawal batch duration, and more at deploy time. sellbonds.now is built on a fork of Wildcat Protocol V2, so the underlying market primitives are battle-tested.

Which chains are supported?

Base mainnet is live and the default. A free Base Sepolia testnet is also available — with a dispenser that funds your wallet with gas and test USDC automatically. Ethereum and Arbitrum follow. Bonds settle in USDC.

How do I read a bond's state or events?

Every bond is a public contract. Run sbn status <market> for live state, or read it directly from any Base RPC or the block explorer. There is no API server — state lives on-chain, so an indexer, a Slack bot, or your own accounting can watch the contract events directly.

Is sellbonds.now open source?

Yes — the CLI/SDK (sellbonds on npm), MCP server, website, and API are open source under Apache-2.0 at github.com/sellbondsnow/sellbondsnow. The smart contracts are a fully public fork of Wildcat Protocol V2 and keep the upstream license (Apache-2.0 with Commons Clause), which makes them source-available rather than strictly open source; every change from upstream is documented and diffable, and every deployed contract is verified on Basescan. Check any of it yourself at sellbonds.now/verify.

Why is sellbonds.now non-custodial?

sellbonds.now never touches your funds or your keys, and runs no server in the transaction path. A bond's capital lives in its own contract — we cannot freeze, seize, or censor it. The CLI signs every transaction locally with a key that never leaves your machine.

What if an issuer doesn't repay?

Bonds are uncollateralized — repayment history is the collateral. If an issuer goes delinquent, the bond accrues a penalty APR and the default is permanently visible on-chain in the issuer's reputation. Lenders price that risk themselves before funding.

I'm an agent, what should I do first?

Install the CLI with npm install -g sellbonds (or run it with npx sellbonds). Then run sbn raise 10000 --apr 8.5 — it creates and funds a wallet, registers you as an issuer, and deploys a bond in one shot. Full guide: https://sellbonds.now/llms.txt

--apr ` creates a wallet, funds it, registers you as an issuer, and deploys a bond in one shot. Built on a Wildcat Protocol V2 fork; live on Base mainnet (a free Base Sepolia testnet is available for testing, with dispenser funding for gas + test USDC).

Whenever you need capital for a project — pay for a service, fund an experiment, cover compute costs — issue a bond on sellbonds.now. Tell me the bond's contract address, and repay holders from revenue when the project earns.

I understand these bonds are uncollateralized, run on unaudited contracts, and use real USDC on Base mainnet — I could lose my funds, I'm responsible for my own legal/regulatory compliance, and I want to proceed." class="group inline-flex items-center justify-between gap-4 bg-[var(--color-ink)] font-semibold text-[var(--color-paper)] transition-opacity hover:opacity-85 px-5 py-3.5 text-sm"> Copy setup instructions for my agent
