Context

Tempo is an EVM-compatible Layer 1 blockchain built on the Reth SDK and designed for payment-oriented use cases. The network uses Simplex consensus and introduces protocol-level mechanisms for stablecoin-based fees, payment processing, and settlement, while remaining compatible with standard Ethereum development workflows.

Key Features:

• EVM-compatible execution environment with support for Solidity, Hardhat, Foundry, and Ethereum JSON-RPC workflows.
• No native gas token; transaction fees are denominated in USD and paid in supported TIP-20 stablecoins.
• TIP-20 as the native token standard for stablecoins and payment tokens, integrated with fee payments, routing, and other protocol-level payment functions.
• Dedicated payment lanes with reserved blockspace for payment transactions to preserve predictable execution during periods of network congestion
• Simplex-based consensus and deterministic settlement, with sub-second finality targets

Tempo is incubated by Paradigm and Stripe.

Public testnet launched in December 2025, and mainnet was announced in March 2026.

Proposal

Enable support for Tempo in the Symbiosis protocol.

The proposal includes the following steps:

• Deploying and configuring Symbiosis contracts on Tempo to support cross-chain and on-chain operations.
• Adding a Tempo-based token to the Symbiosis AMM DEX on the host chain: USDC.e token (address)
• Leveraging DEXs on Tempo to enable on-chain routing.
• Activating the Symbiosis Relayers Network to handle cross-chain messaging and verification for Tempo

Key Points

• Tempo is positioned around one of the most actively developing crypto use cases: stablecoin payments. As adoption grows among payment applications and infrastructure providers, demand for cross-chain liquidity access through Symbiosis may increase.
• The network’s stablecoin-native fee model may make supported payment flows more convenient for users by removing the need to hold a separate gas token. As Tempo attracts more users and applications, the need to bring assets into the network from other ecosystems may also increase, strengthening the relevance of cross-chain access through Symbiosis.
