Roundhouse AI (AQSE:ETHL) on Friday announced it has extended its Dashboard to record x402 payments settled on Solana, adding a third blockchain network alongside Base and Ethereum.
The Singapore-incorporated company, which trades as RHAI on London's AIM market and builds data infrastructure for the autonomous AI agent economy, said the addition brings a significant share of the market into its coverage: Base and Solana together accounted for approximately 98% of cumulative x402 payment volume by value since May 2025, according to data provider DefiLlama as at 4 November. Solana is the third largest public blockchain by stablecoin supply, with around $15 billion of US dollar stablecoins in circulation on the network, DefiLlama figures show.
The Dashboard, live at roundhouseai.io, functions as a searchable record of x402 payments, an open standard that lets AI agents pay for online services directly, with each transaction settled on a public blockchain.
In the 30 days to 2 November, the Dashboard recorded 821,915 x402 payments on Solana worth $341,261, made by 1,425 distinct paying wallets.
Across all three networks it now covers, the running total stands at 202.09 million payments worth $45.58 million, as of 4 November.
"AI agents pay for services wherever those services live, so a record of what they have paid has to follow them across networks," said Matthew Lodge, chief executive of Roundhouse AI.

"We already cover Base and Ethereum. Adding Solana is the next big step towards a more complete picture of the market," he said.
The Dashboard launched in its first version on 11 September, with Facilitator and initial Reputation Graph features enabled; the company has said planned features including Agent Reputation Scores and an aGDP index benchmarking AI agent economic activity will follow once sufficient data has been integrated.
