Swap cACU to ACU
Without Gas Fees
Convert your cACU tokens from the Acurast Canary network (Kusama parachain) to ACU on Acurast Mainnet (Polkadot parachain) at a fixed 2:1 rate. ACU is drawn from an admin-funded liquidity pool. Connect your Polkadot wallet (polkadot.js, Talisman, or SubWallet) to get started.

Smart Contracts
Four Solidity contracts power AcuSwap. Built on OpenZeppelin v5 with ERC-2771 meta-transaction support and ERC-20 Permit for off-chain approvals. The admin funds the ACU liquidity pool, and the bridge relayer handles cross-chain settlement.
Canary network token (Kusama parachain) with gasless approval via EIP-2612
Mainnet token (Polkadot parachain) — admin-funded liquidity pool for swaps
Core swap logic: cACU (Canary) to ACU (Mainnet) at 2:1 with 2% fee
Cross-chain bridge: ACU (Mainnet) to EVM chains at 1:1 with 2% fee
Network Architecture: cACU lives on the Acurast Canary network (Kusama parachain) and ACU lives on Acurast Mainnet (Polkadot parachain). Both are Substrate-based chains. The EVM contracts handle wrapped ACU representations on destination chains like Ethereum, Base, BSC, and Peak.
