How to do your Astar taxes with Koinly
Astar Network is a Polkadot parachain that supports both EVM and WASM smart contracts, rewards developers through dApp staking, and enables cross-chain interoperability with ecosystems like Ethereum and beyond. But if you have Astar transactions, you may have a tax bill. Koinly can help calculate Astar gains, losses, income, and more. All it needs is your Astar transaction history. Here's how to import it.
Follow these steps to sync your Astar (ASTR) data automatically to Koinly:
- Open your Astar (ASTR) wallet app
- Locate and copy your public address or key
On Koinly:
- Create a free account on Koinly
- Complete onboarding until you get to the Wallets page and find Astar (ASTR) in the list
- Select API > Paste the public address/key you copied above in the appropriate box
- Hit Import and wait for Koinly to sync your data. This can take a few minutes
- Review your transactions on the Transactions page to ensure everything is tagged correctly and no missing data
- Go to the Tax Reports page to view your tax liability!
Some transactions may be missing, since the block explorer does not index all transactions. These are mostly rewards and other balances being claimed from dApp contracts

FAQs
What is Astar?
Astar Network is a Polkadot parachain designed for multi-chain smart contracts, supporting both Ethereum’s EVM and WebAssembly (WASM) to make it easier for developers to build dApps across ecosystems. It uses its native token, ASTR, for governance, fees, and staking, and introduces unique models like dApp staking and Build2Earn to reward developers and users who support projects. With growing interoperability, Astar connects Polkadot with Ethereum and other ecosystems, recently expanding through standards like Chainlink CCIP and ERC-7802 to enable seamless cross-chain token transfers and broader adoption.
Is Astar safe?
Astar invests heavily in security, but, like all public blockchains and their DeFi ecosystems, it isn’t risk-free. The core network has undergone third-party reviews (e.g., a Quantstamp audit) and runs an ongoing bug bounty on Immunefi (initially advertised up to $1M; currently listed with a $250k max), which has led to real issues being found and fixed (such as an integer-truncation vulnerability responsibly disclosed and remediated in 2023).
Still, recent events show ecosystem risk: in July 2025, Neemo, a third-party liquid-staking dApp integrated with Astar, was exploited after an admin key was compromised, prompting Astar to pause dApp Staking and coordinate mitigation and reimbursement plans.
Does Astar provide tax documents?
Astar doesn’t provide investors with tax documentation. To figure out your taxes from Astar activity, it’s easiest to use a crypto tax service like Koinly. Once you link your Astar wallet address, Koinly can automatically import your transactions, calculate gains, losses, and income, and create the reports you need for your tax return.
