Payments-First Blockchain Tempo Launched Its Testnet

The Tempo team launched a testnet designed specifically for processing payment operations. The network provides transaction finality in roughly 0.5 seconds, a fixed fee of one-tenth of a cent, and the ability to pay for gas in stablecoins. According to the project team, leading global banks, FinTech companies, and technology corporations already joined the testing, evaluating the network using real payment scenarios.

The testnet offers key features of the infrastructure focused on financial operations:

1. Dedicated payment lanes. The protocol reserves blockspace for transfers, preventing competition with other types of blockchain operations.
2. Gas payments in stablecoins. Transactions fully avoid volatile tokens; all payments and accounting can be conducted in dollar-denominated assets.
3. Built-in decentralized exchange (DEX). The protocol automatically converts stablecoins for fee payments, ensuring a unified liquidity pool and simplifying swaps.
4. Payment metadata. Each transaction can contain structured fields, for example, account numbers or cost centers, which simplifies integration with ERP, TMS, and accounting systems.
5. Deterministic finality. Four validators operating in the testnet confirm blocks in roughly half a second. Future versions are expected to add partner validators.
6. Modern signing mechanisms (passkeys). The protocol supports batch transactions, delayed payments, gas payment logic, and authorization via cryptographic keys.

Tempo’s ecosystem already includes over 40 infrastructure partners providing developer tools, FX solutions, DeFi services, and other integrations.

The network is currently used to test several categories of payment scenarios, including cross-border transfers, global mass payouts, embedded in-app payments, microtransactions, and the use of agent systems and tokenized deposits. The Tempo team emphasizes that low and predictable fees make micro-payment models economically viable, including API billing, content platforms, and IoT services.

Meanwhile, the team is preparing to transition to a fully permissionless architecture. The client code is already open under the Apache license, and independent validators will be able to join the network in the future. The testnet will continue to scale, gaining new developer tools and throughput optimizations for real-world payment loads.

Recently, Stable announced the launch of the mainnet for StableChain, built for stablecoin operations. A month earlier, the Inveniam Chain L2 protocol, focused entirely on tokenization and management of private commercial real-estate assets, began operating in test mode within the MANTRA blockchain ecosystem.
