Astar’s ASTR Becomes First Native SuperchainERC20 Token via Chainlink CCIP

Japan’s Astar Network has just broken new ground: its ASTR token is now the first asset to fully implement the SuperchainERC20 (ERC-7802) standard and Chainlink’s Cross-Chain Interoperability Protocol (CCIP)—opening seamless transfers across the fledgling Optimism Superchain collective.

“This marks the first real-world example of a secure, standards-based architecture for native cross-chain interoperability,” said Maarten Henskens, Head of Astar Foundation. “With ASTR upgraded to a CCIP-SuperchainERC20 token, users can soon move assets across networks in just a couple of clicks.” prnewswire.com

Why It Matters

• Bridge Between Ecosystems
  ASTR can now flow between Astar’s Polkadot-based Layer 1, Sony’s Soneium, and eventually any OP Superchain chain (think Base, OP Mainnet, World Chain, etc.).
• No Wrapped Tokens Needed
  By using burn-and-mint hooks defined in ERC-7802 plus CCIP’s decentralized oracle validation, transfers occur without side-chain liquidity pools or wrapped assets—reducing common bridge exploits.
• Institutional-Grade Security
  Chainlink’s CCIP is backed by its independent Risk Management Network, adding extra monitoring and anomaly detection on every cross-chain call astar.network.

How It Works

1. ERC-7802 Smart Contract
   Astar deployed a new ASTR contract on Soneium implementing crosschainMint and crosschainBurn.
2. CCIP Messaging Layer
   Chainlink validators relay authenticated transfer requests between origin and destination chains.
3. Role-Based Controls
   Only designated CCIP gateways can trigger mints/burns, ensuring rogue actors can’t siphon tokens.

This integration is part of Astar Evolution Phase 1.5, the project’s roadmap for multichain growth.

Tokenomics Tune-Up

ASTR’s supply has felt inflationary pressure—its staking reward was trimmed from 25% to 10%, dropping projected annual inflation from 4.86% to 4.32% in April 2025. That cut alone slices yearly emissions by about 11%, or roughly 360 million fewer tokens. Expect these dynamics to shape ASTR’s liquidity as cross-chain demand grows.

What’s Next?

• Superchain Launch
  Once OP Labs flips the switch on Superchain interoperability, moving ASTR to any connected network will be as easy as transferring between wallets on the same chain.
• DeFi Expansion
  With native cross-chain rails, DeFi protocols on different Superchains can tap ASTR liquidity without relying on third-party bridges.
• Ecosystem Collaboration
  Astar encourages developers to build new cross-chain apps—everything from yield aggregators to NFT marketplaces—using the upgraded ASTR token as their backbone.

This dual integration cements ASTR’s position as one of the first true “multichain” tokens, tying together Polkadot, Ethereum Layer 2s, and beyond.
