Celer Network and Web3 Foundation partnered to integrate Celer's State Channel Network technology into Polkadot, aiming for near-zero cost and real-time
Celer Network is partnering with the Web3 Foundation to integrate its layer-2 scaling solutions into Polkadot, an upcoming blockchain network developed by Parity Technologies [1]. The collaboration, announced recently, aims to enhance Polkadot's performance by enabling faster, lower-cost transactions through Celer's State Channel Network technology [1].

Celer Network specializes in blockchain-agnostic layer-2 scaling solutions, similar to projects like Plasma or the Lightning Network, but with broader functionality [1]. Its core technology, State Channel Networks, is designed to reduce transaction latency and costs to "almost zero," enabling real-time transactions [1]. Co-founder Mo Dong likened Celer's relationship to the Lightning Network as "Celer is to Lightning what Ethereum is to Bitcoin," highlighting its support for full smart contract functionality beyond just payments [1].
The system operates through virtual smart contracts, where participants mutually sign transaction proposals to progress the state of a program off-chain [1]. This approach mitigates the delays and costs associated with confirming every state change directly on the main blockchain [1]. Dong noted that while layer-1 scaling solutions like Ethereum's sharding are being developed, layer-2 solutions will "always be better" for throughput, cost, and latency due to fundamental limitations of decentralized blockchains [1].
Celer will develop a "Pallet" on Substrate, Polkadot's blockchain framework [1]. Unlike traditional smart contracts, Pallets allow developers to build custom chains with basic abstractions for accounts and balances, offering a lower-level, more flexible development environment [1]. Polkadot itself is designed as a sharded blockchain platform focused on interoperability and advanced development capabilities [1].
The integration is expected to optimize communication between layer-1 and layer-2, particularly for dispute resolution [1]. Dong explained that Polkadot's Rust-based environment, with its native ProtoBuf decoder, simplifies the parsing of data structures compared to needing a Solidity parser on Ethereum [1]. This flexibility is crucial for maintaining an interoperable environment where custom chains communicate via the Polkadot protocol [1]. While the partnership has been announced, no estimates are available for when the integration will be live [1].
The partnership between Celer Network and Web3 Foundation aims to enhance Polkadot's scalability and transaction efficiency, positioning it for advanced decentralized applications, though the timeline for full implementation remains unspecified.

Layer 2 Scaling is necessary because Bitcoin and similar blockchains cannot facilitate global-scale transactions without sacrificing decentralization and verifiability. By utilizing a settlement layer on top of the mainchain, Layer 2 Scaling allows for high-frequency transactions while keeping the primary network secure.
Layer 2 Scaling solutions significantly lower costs for users, with the 2024 Dencun upgrade reducing transaction fees on Ethereum Layer 2 networks by over 90%. This shift has moved costs from several dollars per transaction to a range of $0.01 to $0.10.
The primary risk associated with Layer 2 Scaling for Ethereum is the potential siphoning of value and fee revenue away from the main chain. As of November 2025, this migration of activity has caused a slowdown in token burns and fee returns to ETH holders, leading to market volatility.
Layer 2 Scaling designs vary in their reliance on third parties, with early sidechain models often requiring some form of trust. Newer schemes like the Lightning Network and Ark aim to enable Layer 2 Scaling while allowing end users to unilaterally exit back to the mainchain without permission from an operator.
