George Town, Cayman Islands, 14th May 2025, Chainwire – As RWA platforms, DeFi protocols, and enterprises prepare to handle real-world volume and complexity, the limitations of RaaS platforms are becoming harder to ignore: shared sequencers, inherited governance, and rigid upgrade paths are making it harder for teams to deploy infrastructure that adapts to their needs.

Tanssi changes that—by collapsing the cost and complexity of launching a dedicated blockchain from 6–12 months (and $200k+) into a process that takes minutes.

Today, the infrastructure protocol has launched its final testnet before mainnet, marking the start of the staging phase ahead of full availability later this year.

“Tanssi is quickly becoming the go-to infrastructure for RWA projects—especially in Latam, where we’ve secured key partnerships with leading initiatives in Brazil. You can think of it as a convenience layer on top of restaking protocols like Symbiotic and EigenLayer: they introduced the primitives, but access remains complex. Tanssi streamlines that experience for both builders and operators. We’re already seeing teams in RWA, gaming, and AI launch dedicated chains to meet demands for performance, governance, and execution that shared stacks can’t support. This testnet shows that Ethereum-aligned chains can now go live in minutes—not months—and sets the stage for mainnet at scale.” —Thiago Rudiger, CEO of the Tanssi Foundation

Live in the Testnet

  • Symbiotic middleware contracts on Sepolia for permissionless validator onboarding, delegation, and slashing
  • Snowbridge, a trust-minimized Ethereum Tanssi bridge with on-chain light clients—no multisigs or custodians
  • Live sovereign chain, testing runtime logic, validator lifecycle, and cross-chain orchestration
  • Dedicated infra stack (validators, sequencers, RPCs, indexers, explorers) provisioned automatically for every test chain

Why It Matters

App-specific infrastructure is no longer niche. RWAs, DeFi, and coordination platforms now demand fast finality, deterministic execution, and runtime control. Shared RaaS platforms often break down under compliance or latency constraints.

Tanssi abstracts infrastructure overhead—provisioning chains with Ethereum-backed security, isolated sequencing, and customizable runtimes in minutes.

Ecosystem Already Building

  • BLOCKBR, BRX, and Scenium: Launching RWA chains with compliance-grade security.
  • Trexx: Real-time gaming on latency-sensitive infrastructure.
  • Gotas: Social coordination layer that uses NFTs and AI to enhance influencer interactions with their audience.

By the Numbers

  • 57M+ testnet transactions
  • 18,000+ registered chains
  • 150+ ecosystem projects, leading industries include RWA, DeFi, and gaming.
  • $10M raised (Arrington, HashKey, Fenbushi, Borderless, Gavin Wood)
  • 200,000+ community members across 100+ countries

What’s Next

The testnet now serves as the canonical staging environment for:

  • Final validator coordination
  • Staking and governance rollout
  • Developer onboarding at scale

Mainnet is on track for June 2025.

About Tanssi

Tanssi equips developers to launch appchains with Ethereum-backed security—without infrastructure overhead. Built for use cases like RWAs, stablecoins, and coordination protocols, Tanssi automates the full stack: validator orchestration, decentralized sequencing, RPCs, indexers, and explorers—all provisioned out of the box. Teams can launch with a prebuilt EVM chain or customize a Substrate runtime, gaining deterministic performance, fast finality, and full control over governance, fees, and upgrade logic. The result: a sovereign chain, live fast—with no shared bottlenecks or external dependencies.
