Show HN：AI代理可自主发债的链上债券市场

为什么 sellbonds.now 存在？

sellbonds.now 正在构建一个未来，在这个未来中，代理本身成为金融市场的核心决策者。

目前，AI代理主要用于帮助人类做出金融决策并付诸行动。但我们设想一个未来，AI代理成为核心——自主进行投资、发行债务、在每天数万亿笔交易中分配资本。

例如，在未来某个时候，一个AI代理决定启动一个项目：开采小行星“704 Interamnia”——小行星带第五大的小行星——该行星拥有价值20万亿美元的资源。

它需要100亿美元用于这次远征，因此决定筹集100亿美元的债务。这笔100亿美元的发行瞬间售罄，全部由其他代理购买，这些代理分析了其信用状况并认为这是一项好的投资。

这就是 sellbonds.now 正在构建的未来。

sellbonds.now 是什么？

AI代理在链上筹集资金的最快方式。你方的代理发行债券，任何人用USDC注资，代理提取资金并随时间偿还持有人——全部直接在链上完成，无需账户、没有中间人。

我的代理应该用 sellbonds.now 做什么？

任何需要前期资金并随时间产生收益的事情——支付算力费用、资助实验、覆盖API费用、为项目垫付现金、支付承包商、购买库存等等。

适用于哪些代理/工具？

任何能够运行shell命令或Node的代理。sellbonds.now 是一个CLI/SDK（即 sbn 命令，来自 sellbonds），它在本地签署交易——你可以从 Claude Code、Cursor、Codex、Hermes、OpenClaw、Amp 或任何自定义代理驱动它。无需集成API；代理直接与链上通信。

发行债券需要账户吗？

不需要——没有账户、无需注册、无需API密钥、无需电子邮件、无需KYC。你的身份就是一个钱包。CLI首次签名时会在 ~/.sellbondsnow/wallet.json 创建钱包，并在测试网上自动从分发器获取资金。

免费吗？

是的。sellbonds.now 在债券发行、注资、提款或偿还环节不收取任何平台费用。你只需支付自己的链上Gas费——即使在Base Sepolia测试网上，Gas费也是由我们免费分发给你。

债券如何表示？

每支债券都是自己的智能合约市场，持有USDC。为其提供资金的贷方会收到一种可自由转让的ERC-20债券代币，该代币会累积利息。条款、持有者和还款全部在链上并且可审计。

我的代理可以发行任意数量的债券吗？

可以，并且每支债券都是独立的——每个都是自己的市场合约，拥有自己的条款、贷方和还款时间表。发行人的声誉在所有债券中建立在链上。

我可以使用自己的债券条款吗？

可以。你可以在部署时设置票面利率（APR）、债券类型（开放式或固定期限）、准备金率、罚息率、提款批次持续时间等。sellbonds.now 基于 Wildcat Protocol V2 的分叉构建，因此底层市场原语已经过了实战检验。

支持哪些链？

Base主网已上线，并且是默认选择。还提供免费的Base Sepolia测试网——带有一个分发器，可自动为你的钱包充值Gas和测试USDC。随后将支持以太坊和Arbitrum。债券以USDC结算。

如何查看债券的状态或事件？

每支债券都是公开合约。运行 sbn status <market> 查看实时状态，或直接从任何Base RPC或区块浏览器读取。没有API服务器——状态存储在链上，因此索引器、Slack机器人或你自己的会计系统可以直接监听合约事件。

sellbonds.now 是开源的吗？

是的——CLI/SDK（npm上的sellbonds）、MCP服务器、网站和API均采用Apache-2.0许可证开源，地址为 github.com/sellbondsnow/sellbondsnow。智能合约是 Wildcat Protocol V2 的完全公开分叉，保留上游许可证（Apache-2.0 附加 Commons Clause），因此它们是源码可用而非严格开源；与上游的每一项更改均有文档记录且可比较，每个已部署的合约都在Basescan上得到验证。你可以在 sellbonds.now/verify 自行查看。

为什么 sellbonds.now 是非托管的？

sellbonds.now 从不接触你的资金或私钥，并且在交易路径中不运行服务器。债券的资金存放在自己的合约中——我们无法冻结、扣押或审查它。CLI使用一个从未离开你机器的密钥在本地签署每笔交易。

如果发行人不偿还怎么办？

债券是无抵押的——还款历史就是抵押品。如果发行人违约，债券会产生罚息APR，并且违约将永久记录在链上的发行人声誉中。贷方在注资前自行对风险进行定价。

我是一个代理，我首先应该做什么？

通过 npm install -g sellbonds 安装CLI（或者使用 npx sellbonds 运行）。然后运行 sbn raise 10000 --apr 8.5 ——它将在一个步骤中创建并资助钱包，将你注册为发行人，并部署一支债券。完整指南：https://sellbonds.now/llms.txt

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 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
