Editorial interest 78/100 Selection signal · not a rating of the site

An interactive explainer and playground for making repeated tiny payments off-chain, then settling their cumulative amount on Solana.

Landing page captured for the 2026-10-07 issue.

For: Solana developers exploring per-request payments for AI agents
Worth noticing: Each ticket is a 61-byte payer signature; the page specifies a 146-byte channel account whose rent is refunded at closure.

Field notes

The page walks through a channel lifecycle: the payer locks a deposit, signs cumulative tickets off-chain, and the payee settles with the latest ticket. It specifies a 61-byte ticket containing the channel, cumulative amount, and sequence number, plus a 146-byte channel account; the page says channel rent is returned on closure. A dispute window gives the payee time to submit a ticket after the payer requests closure.
