## Key takeaways

- Lightning Labs opened its Wavelength payment toolkit to all users on Bitcoin mainnet, letting AI agents send and receive Lightning Network payments without human approval.
- Agents pay through the L402 protocol with a 0.25% service fee on sending and receiving, on top of normal Lightning routing fees.
- Each mainnet account can hold up to 300,000 satoshis, and users keep self-custody with an exit to the Bitcoin blockchain at any time.

Lightning Labs said its Wavelength payment toolkit is now live on Bitcoin mainnet and open to all users, letting AI agents send and receive Lightning Network payments without a human approving each transfer. [CoinMarketCap](https://coinmarketcap.com/academy/article/lightning-labs-wavelength-ai-agents-bitcoin-mainnet) reported the release. Each mainnet account can hold up to 300,000 satoshis, and the toolkit remains in alpha.

## How Wavelength Agents Pay Over L402

Wavelength agents pay through the L402 protocol, which lets a service charge for an API call or a micropayment-sized data request the way an invoice would, rather than requiring a signup or an API key, according to akta.pro [company records](https://akta.pro/company-data). A group of agents can settle up with each other for services as they go, according to [Lightning Labs](https://akta.pro/company-profiles/00006lk/lightning-labs), without a human approving individual transfers.

Lightning payments carry a 0.25% service fee on both sending and receiving, on top of normal Lightning routing fees, the company said. Moving funds on-chain into or out of Wavelength carries a separate fee that is dynamic but typically minimal, the company said. The toolkit requires no Lightning node to run, no payment channels to manage, and no liquidity to source, Lightning Labs said.

Users retain self-custody of their funds and can move their balance back to the Bitcoin blockchain at any time through an exit command, without approval from Wavelength's settlement coordination service, which the company said never has unilateral control of funds. "This is still an alpha, so tell us what works, what doesn't, and what's missing," Lightning Labs' Michael Levin wrote in the announcement. Stablecoin support is coming soon, the company said; for now, Wavelength moves only Bitcoin.

## Lightning Labs' Earlier Wavelength Releases

Lightning Labs released the alpha version of Wavelength on July 22, 2026, a non-custodial API for integrating self-custodial Bitcoin payments into applications, according to The Defiant. The toolkit supports Lightning payments via atomic swaps and an Ark-like settlement layer, with minimal 1 basis point service fees.

On July 30, 2026, Lightning Labs announced the launch of a dedicated website for L402, a protocol enabling AI agents to pay Lightning invoices to access API endpoints, The Defiant reported. On September 25, 2026, Lightning Labs disclosed two bugs in older Lightning Terminal and lnd versions that could mark canceled Bitcoin Lightning invoices as settled, risking free product delivery, CryptoSlate reported.

## Wavelength's Next Steps

Stablecoin support is coming soon, the company said, without a date. Wavelength remains in alpha, and Lightning Labs asked users to report what works, what does not, and what is missing.
