the fine print

three answers. then the road.

01how the channel works+
open locks a deposit in a channel account on solana. every call adds a fare line to the tape; the meter is the running sum. settle pays the booth owner the tab and returns the rest — deposit = paid + returned, the chain checks the math.
02who collects the toll+
the booth owner — whoever runs the tool — sets the fare and collects the tab at settle. the program has no fee switch and takes no cut; the coin rides alongside and taxes nothing.
03v1 today · the road ahead+
today: real open + settle transfers on mainnet, a replay of a real agent session, fares metered per call. next: the escrow program, signed per-call debits with nonces, refund timeouts, a one-line sdk for tool owners, mcp middleware, usdc channels.
