Our path from protocol design to a global payments network, and the consumer app that puts it in everyone's hands.
Defined the payment primitive model for AT Protocol, mapping atproto DIDs to wallet addresses, designing the lexicon schema for payment records, and selecting Tempo as the settlement layer.
Established initial connectivity to Tempo's public testnet, validated sub-second finality for payment flows, and confirmed stablecoin-denominated gas works for our transaction patterns.
The first public release of the Atmosphere Money SDK for atproto developers. Covers wallet creation, payment requests, gas sponsorship, and firehose event subscriptions.
Full integration guide, API reference, and guided quickstart for building payments into atproto apps. Testnet faucet and sandbox environment for zero-commitment development.
The native payment wallet for AT Protocol enters closed beta. Atpay lets users send, receive, and manage payments directly from their atproto identity using USDB, with no separate wallet setup required.
Integrations with fiat on-ramp and off-ramp providers so users and apps can move between USD and USDB without leaving the Atmosphere ecosystem.
Atpay opens to all users. The first consumer-grade wallet for the open social web, available globally, with support for every app in the Atmosphere ecosystem.
Production-ready SDK release with full documentation, stability guarantees, and a growing library of ecosystem integrations for Bluesky, WhiteWind, and third-party atproto clients.
Atmosphere Money's native US Dollar stablecoin goes live on Tempo testnet. USDat is backed 1:1 by USD held in short-term US Treasury Bills. The yield generated by these reserves funds the Tempo Paymaster — delivering zero gas fees for all users from day one.
USDat moves to Tempo mainnet as the global reserve currency of the Atmosphere. Full reserve audits published, compliance registry live, and programmatic mint/redeem open to all verified integrators. The Tempo Paymaster goes live, subsidising all network transaction fees from Treasury yield.
Once core network effects are proven with USDat, Atmosphere launches EURat — a Euro-pegged stablecoin built for full compliance with the EU's MiCA (Markets in Crypto-Assets) framework. To prevent liquidity fragmentation, cross-currency settlement is handled entirely at the protocol layer via Invisible Auto-FX.
Programmable accounts for AI agents, enabling autonomous commerce, microtransaction-based API billing via MPP streaming sessions, and agent-to-agent payments on AT Protocol and across the open web.
Expand USDat and EURat beyond the Atmosphere — interoperability with other decentralized social protocols, additional fiat corridors, and enterprise API access for embedded finance.
